-#CC= $(DEFAULT_CC) -m32
-#
-# Since the assembler part does NOT maintain a frame pointer, it's pointless
-# to slow down the C part by not omitting it. Debugging, tracebacks and
-# unwinding are not affected -- the assembler part has frame unwind
-# information and GCC emits it where needed (x64) or with -g (see CCDEBUG).
-CCOPT= -O2 -fomit-frame-pointer
-# Use this if you want to generate a smaller binary (but it's slower):
-#CCOPT= -Os -fomit-frame-pointer
-# Note: it's no longer recommended to use -O3 with GCC 4.x.
-# The I-Cache bloat usually outweighs the benefits from aggressive inlining.
-#
-# Target-specific compiler options:
-#
-# x86/x64 only: For GCC 4.2 or higher and if you don't intend to distribute
-# the binaries to a different machine you could also use: -march=native

-# Permanently disable the FFI extension to reduce the size of the LuaJIT

-# but NOT loaded by default. It only allocates any memory, if you actually
-# make use of it.
-#XCFLAGS+= -DLUAJIT_DISABLE_FFI
-#
-# Features from Lua 5.2 that are unlikely to break existing code are
-# enabled by default. Some other features that *might* break some existing
-# code (e.g. __pairs or os.execute() return values) can be enabled here.
-# Note: this does not provide full compatibility with Lua 5.2 at this time.
-#XCFLAGS+= -DLUAJIT_ENABLE_LUA52COMPAT
-#
-# Disable the JIT compiler, i.e. turn LuaJIT into a pure interpreter.
-#XCFLAGS+= -DLUAJIT_DISABLE_JIT
-#
-# Some architectures (e.g. PPC) can use either single-number (1) or
-# dual-number (2) mode. Uncomment one of these lines to override the
-# default mode. Please see LJ_ARCH_NUMMODE in lj_arch.h for details.
-#XCFLAGS+= -DLUAJIT_NUMMODE=1

-############################  DEBUGGING SUPPORT  #############################
-##############################################################################
-# Enable these options as needed, but make sure you force a full recompile
-# with "make clean", followed by "make".
-# Note that most of these are NOT suitable for benchmarking or release mode!
-#
-# Use the system provided memory allocator (realloc) instead of the
-# bundled memory allocator. This is slower, but sometimes helpful for
-# debugging. This option cannot be enabled on x64 without GC64, since
-# realloc usually doesn't return addresses in the right address range.
-# OTOH this option is mandatory for Valgrind's memcheck tool on x64 and
-# the only way to get useful results from it for all other architectures.
-#XCFLAGS+= -DLUAJIT_USE_SYSMALLOC
-#
-# This define is required to run LuaJIT under Valgrind. The Valgrind
-# header files must be installed. You should enable debug information, too.
-# Use --suppressions=lj.supp to avoid some false positives.
-#XCFLAGS+= -DLUAJIT_USE_VALGRIND
-#
-# This is the client for the GDB JIT API. GDB 7.0 or higher is required
-# to make use of it. See lj_gdbjit.c for details. Enabling this causes
-# a non-negligible overhead, even when not running under GDB.
-#XCFLAGS+= -DLUAJIT_USE_GDBJIT
-#
-# Turn on assertions for the Lua/C API to debug problems with lua_* calls.
-# This is rather slow -- use only while developing C libraries/embeddings.
-#XCFLAGS+= -DLUA_USE_APICHECK
-#
-# Turn on assertions for the whole LuaJIT VM. This significantly slows down
-# everything. Use only if you suspect a problem with LuaJIT itself.

+LuaJIT adds some extensions to the standard Lua/C API. The LuaJIT include
+directory must be in the compiler search path (<tt>-I<i>path</i></tt>)
+to be able to include the required header for C code:
+</p>
+<pre class="code">
+#include "luajit.h"
+</pre>
+<p>
+Or for C++ code:
+</p>
+<pre class="code">
+#include "lua.hpp"
+</pre>
+
+<h2 id="luaJIT_setmode"><tt>luaJIT_setmode(L, idx, mode)</tt>
+&mdash; Control VM</h2>
+<p>
+This is a C API extension to allow control of the VM from C code. The
+full prototype of <tt>LuaJIT_setmode</tt> is:
+</p>
+<pre class="code">
+LUA_API int luaJIT_setmode(lua_State *L, int idx, int mode);
+</pre>
+<p>
+The returned status is either success (<tt>1</tt>) or failure (<tt>0</tt>).
+The second argument is either <tt>0</tt> or a stack index (similar to the
+other Lua/C API functions).
+</p>
+<p>
+The third argument specifies the mode, which is 'or'ed with a flag.
+The flag can be <tt>LUAJIT_MODE_OFF</tt> to turn a feature off,
+<tt>LUAJIT_MODE_ON</tt> to turn a feature on, or
+<tt>LUAJIT_MODE_FLUSH</tt> to flush cached code.
+</p>
+<p>
+The following modes are defined:
+</p>
+
+<h3 id="mode_engine"><tt>luaJIT_setmode(L, 0, LUAJIT_MODE_ENGINE|flag)</tt></h3>
+<p>
+Turn the whole JIT compiler on or off or flush the whole cache of compiled code.
+</p>
+
+<h3 id="mode_func"><tt>luaJIT_setmode(L, idx, LUAJIT_MODE_FUNC|flag)</tt><br>
+<tt>luaJIT_setmode(L, idx, LUAJIT_MODE_ALLFUNC|flag)</tt><br>
+<tt>luaJIT_setmode(L, idx, LUAJIT_MODE_ALLSUBFUNC|flag)</tt></h3>
+<p>
+This sets the mode for the function at the stack index <tt>idx</tt> or
+the parent of the calling function (<tt>idx = 0</tt>). It either
+enables JIT compilation for a function, disables it and flushes any
+already compiled code or only flushes already compiled code. This
+applies recursively to all sub-functions of the function with
+<tt>LUAJIT_MODE_ALLFUNC</tt> or only to the sub-functions with
+<tt>LUAJIT_MODE_ALLSUBFUNC</tt>.
+</p>
+
+<h3 id="mode_trace"><tt>luaJIT_setmode(L, trace,<br>
+&nbsp;&nbsp;LUAJIT_MODE_TRACE|LUAJIT_MODE_FLUSH)</tt></h3>
+<p>
+Flushes the specified root trace and all of its side traces from the cache.
+The code for the trace will be retained as long as there are any other
+traces which link to it.
+</p>
+
+<h3 id="mode_wrapcfunc"><tt>luaJIT_setmode(L, idx, LUAJIT_MODE_WRAPCFUNC|flag)</tt></h3>
+<p>
+This mode defines a wrapper function for calls to C functions. If
+called with <tt>LUAJIT_MODE_ON</tt>, the stack index at <tt>idx</tt>
+must be a <tt>lightuserdata</tt> object holding a pointer to the wrapper
+function. From now on all C functions are called through the wrapper
+function. If called with <tt>LUAJIT_MODE_OFF</tt> this mode is turned
+off and all C functions are directly called.
+</p>
+<p>
+The wrapper function can be used for debugging purposes or to catch
+and convert foreign exceptions. But please read the section on
+<a href="extensions.html#exceptions">C++&nbsp;exception interoperability</a>
+first. Recommended usage can be seen in this C++ code excerpt:
+</p>
+<pre class="code">
+#include &lt;exception&gt;
+#include "lua.hpp"
+
+// Catch C++ exceptions and convert them to Lua error messages.
+// Customize as needed for your own exception classes.
+static int wrap_exceptions(lua_State *L, lua_CFunction f)
+{
+  try {
+    return f(L);  // Call wrapped function and return result.
+  } catch (const char *s) {  // Catch and convert exceptions.
+    lua_pushstring(L, s);
+  } catch (std::exception& e) {
+    lua_pushstring(L, e.what());
+  } catch (...) {
+    lua_pushliteral(L, "caught (...)");
+  }
+  return lua_error(L);  // Rethrow as a Lua error.
+}
+
+static int myinit(lua_State *L)
+{
+  ...
+  // Define wrapper function and enable it.
+  lua_pushlightuserdata(L, (void *)wrap_exceptions);
+  luaJIT_setmode(L, -1, LUAJIT_MODE_WRAPCFUNC|LUAJIT_MODE_ON);
+  lua_pop(L, 1);
+  ...
+}
+</pre>
+<p>
+Note that you can only define <b>a single global wrapper function</b>,
+so be careful when using this mechanism from multiple C++ modules.
+Also note that this mechanism is not without overhead.

+
+The FFI library allows <b>calling external C&nbsp;functions</b> and
+<b>using C&nbsp;data structures</b> from pure Lua code.
+
+</p>
+<p>
+
+The FFI library largely obviates the need to write tedious manual
+Lua/C bindings in C. No need to learn a separate binding language
+&mdash; <b>it parses plain C&nbsp;declarations!</b> These can be
+cut-n-pasted from C&nbsp;header files or reference manuals. It's up to
+the task of binding large libraries without the need for dealing with
+fragile binding generators.
+
+</p>
+<p>
+The FFI library is tightly integrated into LuaJIT (it's not available
+as a separate module). The code generated by the JIT-compiler for
+accesses to C&nbsp;data structures from Lua code is on par with the
+code a C&nbsp;compiler would generate. Calls to C&nbsp;functions can
+be inlined in JIT-compiled code, unlike calls to functions bound via
+the classic Lua/C API.
+</p>
+<p>
+This page gives a short introduction to the usage of the FFI library.
+<em>Please use the FFI sub-topics in the navigation bar to learn more.</em>
+</p>
+
+<h2 id="call">Motivating Example: Calling External C Functions</h2>
+<p>
+It's really easy to call an external C&nbsp;library function:

+<span class="codemark">&#9312;
+&#9313;
+
+
+&#9314;</span>local ffi = require("ffi")
+ffi.cdef[[
+<span style="color:#00a000;">int printf(const char *fmt, ...);</span>
+]]
+ffi.C.printf("Hello %s!", "world")
+</pre>
+<p>
+So, let's pick that apart:
+</p>
+<p>
+<span class="mark">&#9312;</span> Load the FFI library.
+</p>
+<p>
+<span class="mark">&#9313;</span> Add a C&nbsp;declaration
+for the function. The part inside the double-brackets (in green) is
+just standard C&nbsp;syntax.
+</p>
+<p>
+<span class="mark">&#9314;</span> Call the named
+C&nbsp;function &mdash; Yes, it's that simple!
+</p>
+<p style="font-size: 8pt;">
+Actually, what goes on behind the scenes is far from simple: <span
+style="color:#4040c0;">&#9314;</span> makes use of the standard
+C&nbsp;library namespace <tt>ffi.C</tt>. Indexing this namespace with
+a symbol name (<tt>"printf"</tt>) automatically binds it to the
+standard C&nbsp;library. The result is a special kind of object which,
+when called, runs the <tt>printf</tt> function. The arguments passed
+to this function are automatically converted from Lua objects to the
+corresponding C&nbsp;types.
+</p>
+<p>
+Ok, so maybe the use of <tt>printf()</tt> wasn't such a spectacular
+example. You could have done that with <tt>io.write()</tt> and
+<tt>string.format()</tt>, too. But you get the idea ...
+</p>
+<p>
+So here's something to pop up a message box on Windows:
+</p>
+<pre class="code">
+local ffi = require("ffi")
+ffi.cdef[[
+<span style="color:#00a000;">int MessageBoxA(void *w, const char *txt, const char *cap, int type);</span>
+]]
+ffi.C.MessageBoxA(nil, "Hello world!", "Test", 0)
+</pre>
+<p>
+Bing! Again, that was far too easy, no?
+</p>
+<p style="font-size: 8pt;">
+Compare this with the effort required to bind that function using the
+classic Lua/C API: create an extra C&nbsp;file, add a C&nbsp;function
+that retrieves and checks the argument types passed from Lua and calls
+the actual C&nbsp;function, add a list of module functions and their
+names, add a <tt>luaopen_*</tt> function and register all module
+functions, compile and link it into a shared library (DLL), move it to
+the proper path, add Lua code that loads the module aaaand ... finally
+call the binding function. Phew!
+</p>
+
+<h2 id="cdata">Motivating Example: Using C Data Structures</h2>
+<p>
+The FFI library allows you to create and access C&nbsp;data
+structures. Of course the main use for this is for interfacing with
+C&nbsp;functions. But they can be used stand-alone, too.
+</p>
+<p>
+Lua is built upon high-level data types. They are flexible, extensible
+and dynamic. That's why we all love Lua so much. Alas, this can be
+inefficient for certain tasks, where you'd really want a low-level
+data type. E.g. a large array of a fixed structure needs to be
+implemented with a big table holding lots of tiny tables. This imposes
+both a substantial memory overhead as well as a performance overhead.
+</p>
+<p>
+Here's a sketch of a library that operates on color images plus a
+simple benchmark. First, the plain Lua version:
+</p>
+<pre class="code">
+local floor = math.floor
+
+local function image_ramp_green(n)
+  local img = {}
+  local f = 255/(n-1)
+  for i=1,n do
+    img[i] = { red = 0, green = floor((i-1)*f), blue = 0, alpha = 255 }
+  end
+  return img
+end
+
+local function image_to_grey(img, n)
+  for i=1,n do
+    local y = floor(0.3*img[i].red + 0.59*img[i].green + 0.11*img[i].blue)
+    img[i].red = y; img[i].green = y; img[i].blue = y
+  end
+end
+
+local N = 400*400
+local img = image_ramp_green(N)
+for i=1,1000 do
+  image_to_grey(img, N)
+end
+</pre>
+<p>
+This creates a table with 160.000 pixels, each of which is a table
+holding four number values in the range of 0-255. First an image with
+a green ramp is created (1D for simplicity), then the image is
+converted to greyscale 1000 times. Yes, that's silly, but I was in
+need of a simple example ...
+</p>
+<p>
+And here's the FFI version. The modified parts have been marked in
+bold:
+</p>
+<pre class="code mark">
+<span class="codemark">&#9312;
+
+
+
+
+
+&#9313;
+
+&#9314;
+&#9315;
+
+
+
+
+
+
+&#9314;
+&#9316;</span><b>local ffi = require("ffi")
+ffi.cdef[[
+</b><span style="color:#00a000;">typedef struct { uint8_t red, green, blue, alpha; } rgba_pixel;</span><b>
+]]</b>
+
+local function image_ramp_green(n)
+  <b>local img = ffi.new("rgba_pixel[?]", n)</b>
+  local f = 255/(n-1)
+  for i=<b>0,n-1</b> do
+    <b>img[i].green = i*f</b>
+    <b>img[i].alpha = 255</b>
+  end
+  return img
+end
+
+local function image_to_grey(img, n)
+  for i=<b>0,n-1</b> do
+    local y = <b>0.3*img[i].red + 0.59*img[i].green + 0.11*img[i].blue</b>
+    img[i].red = y; img[i].green = y; img[i].blue = y
+  end
+end
+
+local N = 400*400
+local img = image_ramp_green(N)
+for i=1,1000 do
+  image_to_grey(img, N)
+end
+</pre>
+<p>
+Ok, so that wasn't too difficult:
+</p>
+<p>
+<span class="mark">&#9312;</span> First, load the FFI
+library and declare the low-level data type. Here we choose a
+<tt>struct</tt> which holds four byte fields, one for each component
+of a 4x8&nbsp;bit RGBA pixel.
+</p>
+<p>
+<span class="mark">&#9313;</span> Creating the data
+structure with <tt>ffi.new()</tt> is straightforward &mdash; the
+<tt>'?'</tt> is a placeholder for the number of elements of a
+variable-length array.
+</p>
+<p>
+<span class="mark">&#9314;</span> C&nbsp;arrays are
+zero-based, so the indexes have to run from <tt>0</tt> to
+<tt>n-1</tt>. One might want to allocate one more element instead to
+simplify converting legacy code.
+</p>
+<p>
+<span class="mark">&#9315;</span> Since <tt>ffi.new()</tt>
+zero-fills the array by default, we only need to set the green and the
+alpha fields.
+</p>
+<p>
+<span class="mark">&#9316;</span> The calls to
+<tt>math.floor()</tt> can be omitted here, because floating-point
+numbers are already truncated towards zero when converting them to an
+integer. This happens implicitly when the number is stored in the
+fields of each pixel.
+</p>
+<p>
+Now let's have a look at the impact of the changes: first, memory
+consumption for the image is down from 22&nbsp;Megabytes to
+640&nbsp;Kilobytes (400*400*4 bytes). That's a factor of 35x less! So,
+yes, tables do have a noticeable overhead. BTW: The original program
+would consume 40&nbsp;Megabytes in plain Lua (on x64).
+</p>
+<p>
+Next, performance: the pure Lua version runs in 9.57 seconds (52.9
+seconds with the Lua interpreter) and the FFI version runs in 0.48
+seconds on my machine (YMMV). That's a factor of 20x faster (110x
+faster than the Lua interpreter).
+</p>
+<p style="font-size: 8pt;">
+The avid reader may notice that converting the pure Lua version over
+to use array indexes for the colors (<tt>[1]</tt> instead of
+<tt>.red</tt>, <tt>[2]</tt> instead of <tt>.green</tt> etc.) ought to
+be more compact and faster. This is certainly true (by a factor of
+~1.7x). Switching to a struct-of-arrays would help, too.
+</p>
+<p style="font-size: 8pt;">
+However the resulting code would be less idiomatic and rather
+error-prone. And it still doesn't get even close to the performance of
+the FFI version of the code. Also, high-level data structures cannot
+be easily passed to other C&nbsp;functions, especially I/O functions,
+without undue conversion penalties.

+This page describes the API functions provided by the FFI library in
+detail. It's recommended to read through the
+<a href="ext_ffi.html">introduction</a> and the
+<a href="ext_ffi_tutorial.html">FFI tutorial</a> first.
+</p>
+
+<h2 id="glossary">Glossary</h2>
+<ul>
+<li><b>cdecl</b> &mdash; An abstract C&nbsp;type declaration (a Lua
+string).</li>
+<li><b>ctype</b> &mdash; A C&nbsp;type object. This is a special kind of
+<b>cdata</b> returned by <tt>ffi.typeof()</tt>. It serves as a
+<b>cdata</b> <a href="#ffi_new">constructor</a> when called.</li>
+<li><b>cdata</b> &mdash; A C&nbsp;data object. It holds a value of the
+corresponding <b>ctype</b>.</li>
+<li><b>ct</b> &mdash; A C&nbsp;type specification which can be used for
+most of the API functions. Either a <b>cdecl</b>, a <b>ctype</b> or a
+<b>cdata</b> serving as a template type.</li>
+<li><b>cb</b> &mdash; A callback object. This is a C&nbsp;data object
+holding a special function pointer. Calling this function from
+C&nbsp;code runs an associated Lua function.</li>
+<li><b>VLA</b> &mdash; A variable-length array is declared with a
+<tt>?</tt> instead of the number of elements, e.g. <tt>"int[?]"</tt>.
+The number of elements (<tt>nelem</tt>) must be given when it's
+<a href="#ffi_new">created</a>.</li>
+<li><b>VLS</b> &mdash; A variable-length struct is a <tt>struct</tt> C
+type where the last element is a <b>VLA</b>. The same rules for
+declaration and creation apply.</li>
+</ul>
+
+<h2 id="decl">Declaring and Accessing External Symbols</h2>
+<p>
+External symbols must be declared first and can then be accessed by
+indexing a <a href="ext_ffi_semantics.html#clib">C&nbsp;library
+namespace</a>, which automatically binds the symbol to a specific
+library.
+</p>
+
+<h3 id="ffi_cdef"><tt>ffi.cdef(def)</tt></h3>
+<p>
+Adds multiple C&nbsp;declarations for types or external symbols (named
+variables or functions). <tt>def</tt> must be a Lua string. It's
+recommended to use the syntactic sugar for string arguments as
+follows:
+</p>
+<pre class="code">
+ffi.cdef[[
+<span style="color:#00a000;">typedef struct foo { int a, b; } foo_t;  // Declare a struct and typedef.
+int dofoo(foo_t *f, int n);  /* Declare an external C function. */</span>
+]]
+</pre>
+<p>
+The contents of the string (the part in green above) must be a
+sequence of
+<a href="ext_ffi_semantics.html#clang">C&nbsp;declarations</a>,
+separated by semicolons. The trailing semicolon for a single
+declaration may be omitted.
+</p>
+<p>
+Please note that external symbols are only <em>declared</em>, but they
+are <em>not bound</em> to any specific address, yet. Binding is
+achieved with C&nbsp;library namespaces (see below).
+</p>
+<p style="color: #c00000;">
+C&nbsp;declarations are not passed through a C&nbsp;pre-processor,
+yet. No pre-processor tokens are allowed, except for
+<tt>#pragma&nbsp;pack</tt>. Replace <tt>#define</tt> in existing
+C&nbsp;header files with <tt>enum</tt>, <tt>static&nbsp;const</tt>
+or <tt>typedef</tt> and/or pass the files through an external
+C&nbsp;pre-processor (once). Be careful not to include unneeded or
+redundant declarations from unrelated header files.
+</p>
+
+<h3 id="ffi_C"><tt>ffi.C</tt></h3>
+<p>
+This is the default C&nbsp;library namespace &mdash; note the
+uppercase <tt>'C'</tt>. It binds to the default set of symbols or
+libraries on the target system. These are more or less the same as a
+C&nbsp;compiler would offer by default, without specifying extra link
+libraries.
+</p>
+<p>
+On POSIX systems, this binds to symbols in the default or global
+namespace. This includes all exported symbols from the executable and
+any libraries loaded into the global namespace. This includes at least
+<tt>libc</tt>, <tt>libm</tt>, <tt>libdl</tt> (on Linux),
+<tt>libgcc</tt> (if compiled with GCC), as well as any exported
+symbols from the Lua/C&nbsp;API provided by LuaJIT itself.
+</p>
+<p>
+On Windows systems, this binds to symbols exported from the
+<tt>*.exe</tt>, the <tt>lua51.dll</tt> (i.e. the Lua/C&nbsp;API
+provided by LuaJIT itself), the C&nbsp;runtime library LuaJIT was linked
+with (<tt>msvcrt*.dll</tt>), <tt>kernel32.dll</tt>,
+<tt>user32.dll</tt> and <tt>gdi32.dll</tt>.
+</p>
+
+<h3 id="ffi_load"><tt>clib = ffi.load(name [,global])</tt></h3>
+<p>
+This loads the dynamic library given by <tt>name</tt> and returns
+a new C&nbsp;library namespace which binds to its symbols. On POSIX
+systems, if <tt>global</tt> is <tt>true</tt>, the library symbols are
+loaded into the global namespace, too.
+</p>
+<p>
+If <tt>name</tt> is a path, the library is loaded from this path.
+Otherwise <tt>name</tt> is canonicalized in a system-dependent way and
+searched in the default search path for dynamic libraries:
+</p>
+<p>
+On POSIX systems, if the name contains no dot, the extension
+<tt>.so</tt> is appended. Also, the <tt>lib</tt> prefix is prepended
+if necessary. So <tt>ffi.load("z")</tt> looks for <tt>"libz.so"</tt>
+in the default shared library search path.
+</p>
+<p>
+On Windows systems, if the name contains no dot, the extension
+<tt>.dll</tt> is appended. So <tt>ffi.load("ws2_32")</tt> looks for
+<tt>"ws2_32.dll"</tt> in the default DLL search path.
+</p>
+
+<h2 id="create">Creating cdata Objects</h2>
+<p>
+The following API functions create cdata objects (<tt>type()</tt>
+returns <tt>"cdata"</tt>). All created cdata objects are
+<a href="ext_ffi_semantics.html#gc">garbage collected</a>.
+</p>
+
+<h3 id="ffi_new"><tt>cdata = ffi.new(ct [,nelem] [,init...])<br>
+cdata = <em>ctype</em>([nelem,] [init...])</tt></h3>
+<p>
+Creates a cdata object for the given <tt>ct</tt>. VLA/VLS types
+require the <tt>nelem</tt> argument. The second syntax uses a ctype as
+a constructor and is otherwise fully equivalent.
+</p>
+<p>
+The cdata object is initialized according to the
+<a href="ext_ffi_semantics.html#init">rules for initializers</a>,
+using the optional <tt>init</tt> arguments. Excess initializers cause
+an error.
+</p>
+<p>
+Performance notice: if you want to create many objects of one kind,
+parse the cdecl only once and get its ctype with
+<tt>ffi.typeof()</tt>. Then use the ctype as a constructor repeatedly.
+</p>
+<p style="font-size: 8pt;">
+Please note that an anonymous <tt>struct</tt> declaration implicitly
+creates a new and distinguished ctype every time you use it for
+<tt>ffi.new()</tt>. This is probably <b>not</b> what you want,
+especially if you create more than one cdata object. Different anonymous
+<tt>structs</tt> are not considered assignment-compatible by the
+C&nbsp;standard, even though they may have the same fields! Also, they
+are considered different types by the JIT-compiler, which may cause an
+excessive number of traces. It's strongly suggested to either declare
+a named <tt>struct</tt> or <tt>typedef</tt> with <tt>ffi.cdef()</tt>
+or to create a single ctype object for an anonymous <tt>struct</tt>
+with <tt>ffi.typeof()</tt>.
+</p>
+
+<h3 id="ffi_typeof"><tt>ctype = ffi.typeof(ct)</tt></h3>
+<p>
+Creates a ctype object for the given <tt>ct</tt>.
+</p>
+<p>
+This function is especially useful to parse a cdecl only once and then
+use the resulting ctype object as a <a href="#ffi_new">constructor</a>.
+</p>
+
+<h3 id="ffi_cast"><tt>cdata = ffi.cast(ct, init)</tt></h3>
+<p>
+Creates a scalar cdata object for the given <tt>ct</tt>. The cdata
+object is initialized with <tt>init</tt> using the "cast" variant of
+the <a href="ext_ffi_semantics.html#convert">C&nbsp;type conversion
+rules</a>.
+</p>
+<p>
+This functions is mainly useful to override the pointer compatibility
+checks or to convert pointers to addresses or vice versa.
+</p>
+
+<h3 id="ffi_metatype"><tt>ctype = ffi.metatype(ct, metatable)</tt></h3>
+<p>
+Creates a ctype object for the given <tt>ct</tt> and associates it with
+a metatable. Only <tt>struct</tt>/<tt>union</tt> types, complex numbers
+and vectors are allowed. Other types may be wrapped in a
+<tt>struct</tt>, if needed.
+</p>
+<p>
+The association with a metatable is permanent and cannot be changed
+afterwards. Neither the contents of the <tt>metatable</tt> nor the
+contents of an <tt>__index</tt> table (if any) may be modified
+afterwards. The associated metatable automatically applies to all uses
+of this type, no matter how the objects are created or where they
+originate from. Note that pre-defined operations on types have
+precedence (e.g. declared field names cannot be overriden).
+</p>
+<p>
+All standard Lua metamethods are implemented. These are called directly,
+without shortcuts and on any mix of types. For binary operations, the
+left operand is checked first for a valid ctype metamethod. The
+<tt>__gc</tt> metamethod only applies to <tt>struct</tt>/<tt>union</tt>
+types and performs an implicit <a href="#ffi_gc"><tt>ffi.gc()</tt></a>
+call during creation of an instance.
+</p>
+
+<h3 id="ffi_gc"><tt>cdata = ffi.gc(cdata, finalizer)</tt></h3>
+<p>
+Associates a finalizer with a pointer or aggregate cdata object. The
+cdata object is returned unchanged.
+</p>
+<p>
+This function allows safe integration of unmanaged resources into the
+automatic memory management of the LuaJIT garbage collector. Typical
+usage:
+</p>
+<pre class="code">
+local p = ffi.gc(ffi.C.malloc(n), ffi.C.free)
+...
+p = nil -- Last reference to p is gone.
+-- GC will eventually run finalizer: ffi.C.free(p)
+</pre>
+<p>
+A cdata finalizer works like the <tt>__gc</tt> metamethod for userdata
+objects: when the last reference to a cdata object is gone, the
+associated finalizer is called with the cdata object as an argument. The
+finalizer can be a Lua function or a cdata function or cdata function
+pointer. An existing finalizer can be removed by setting a <tt>nil</tt>
+finalizer, e.g. right before explicitly deleting a resource:
+</p>
+<pre class="code">
+ffi.C.free(ffi.gc(p, nil)) -- Manually free the memory.
+</pre>
+
+<h2 id="info">C&nbsp;Type Information</h2>
+<p>
+The following API functions return information about C&nbsp;types.
+They are most useful for inspecting cdata objects.
+</p>
+
+<h3 id="ffi_sizeof"><tt>size = ffi.sizeof(ct [,nelem])</tt></h3>
+<p>
+Returns the size of <tt>ct</tt> in bytes. Returns <tt>nil</tt> if
+the size is not known (e.g. for <tt>"void"</tt> or function types).
+Requires <tt>nelem</tt> for VLA/VLS types, except for cdata objects.
+</p>
+
+<h3 id="ffi_alignof"><tt>align = ffi.alignof(ct)</tt></h3>
+<p>
+Returns the minimum required alignment for <tt>ct</tt> in bytes.
+</p>
+
+<h3 id="ffi_offsetof"><tt>ofs [,bpos,bsize] = ffi.offsetof(ct, field)</tt></h3>
+<p>
+Returns the offset (in bytes) of <tt>field</tt> relative to the start
+of <tt>ct</tt>, which must be a <tt>struct</tt>. Additionally returns
+the position and the field size (in bits) for bit fields.
+</p>
+
+<h3 id="ffi_istype"><tt>status = ffi.istype(ct, obj)</tt></h3>
+<p>
+Returns <tt>true</tt> if <tt>obj</tt> has the C&nbsp;type given by
+<tt>ct</tt>. Returns <tt>false</tt> otherwise.
+</p>
+<p>
+C&nbsp;type qualifiers (<tt>const</tt> etc.) are ignored. Pointers are
+checked with the standard pointer compatibility rules, but without any
+special treatment for <tt>void&nbsp;*</tt>. If <tt>ct</tt> specifies a
+<tt>struct</tt>/<tt>union</tt>, then a pointer to this type is accepted,
+too. Otherwise the types must match exactly.
+</p>
+<p>
+Note: this function accepts all kinds of Lua objects for the
+<tt>obj</tt> argument, but always returns <tt>false</tt> for non-cdata
+objects.

+
+<h2 id="util">Utility Functions</h2>
+
+<h3 id="ffi_errno"><tt>err = ffi.errno([newerr])</tt></h3>
+<p>
+Returns the error number set by the last C&nbsp;function call which
+indicated an error condition. If the optional <tt>newerr</tt> argument
+is present, the error number is set to the new value and the previous
+value is returned.
+</p>
+<p>
+This function offers a portable and OS-independent way to get and set the
+error number. Note that only <em>some</em> C&nbsp;functions set the error
+number. And it's only significant if the function actually indicated an
+error condition (e.g. with a return value of <tt>-1</tt> or
+<tt>NULL</tt>). Otherwise, it may or may not contain any previously set
+value.
+</p>
+<p>
+You're advised to call this function only when needed and as close as
+possible after the return of the related C&nbsp;function. The
+<tt>errno</tt> value is preserved across hooks, memory allocations,
+invocations of the JIT compiler and other internal VM activity. The same
+applies to the value returned by <tt>GetLastError()</tt> on Windows, but
+you need to declare and call it yourself.
+</p>
+
+<h3 id="ffi_string"><tt>str = ffi.string(ptr [,len])</tt></h3>
+<p>
+Creates an interned Lua string from the data pointed to by
+<tt>ptr</tt>.
+</p>
+<p>
+If the optional argument <tt>len</tt> is missing, <tt>ptr</tt> is
+converted to a <tt>"char&nbsp;*"</tt> and the data is assumed to be
+zero-terminated. The length of the string is computed with
+<tt>strlen()</tt>.
+</p>
+<p>
+Otherwise <tt>ptr</tt> is converted to a <tt>"void&nbsp;*"</tt> and
+<tt>len</tt> gives the length of the data. The data may contain
+embedded zeros and need not be byte-oriented (though this may cause
+endianess issues).
+</p>
+<p>
+This function is mainly useful to convert (temporary)
+<tt>"const&nbsp;char&nbsp;*"</tt> pointers returned by
+C&nbsp;functions to Lua strings and store them or pass them to other
+functions expecting a Lua string. The Lua string is an (interned) copy
+of the data and bears no relation to the original data area anymore.
+Lua strings are 8&nbsp;bit clean and may be used to hold arbitrary,
+non-character data.
+</p>
+<p>
+Performance notice: it's faster to pass the length of the string, if
+it's known. E.g. when the length is returned by a C&nbsp;call like
+<tt>sprintf()</tt>.
+</p>
+
+<h3 id="ffi_copy"><tt>ffi.copy(dst, src, len)<br>
+ffi.copy(dst, str)</tt></h3>
+<p>
+Copies the data pointed to by <tt>src</tt> to <tt>dst</tt>.
+<tt>dst</tt> is converted to a <tt>"void&nbsp;*"</tt> and <tt>src</tt>
+is converted to a <tt>"const void&nbsp;*"</tt>.
+</p>
+<p>
+In the first syntax, <tt>len</tt> gives the number of bytes to copy.
+Caveat: if <tt>src</tt> is a Lua string, then <tt>len</tt> must not
+exceed <tt>#src+1</tt>.
+</p>
+<p>
+In the second syntax, the source of the copy must be a Lua string. All
+bytes of the string <em>plus a zero-terminator</em> are copied to
+<tt>dst</tt> (i.e. <tt>#src+1</tt> bytes).
+</p>
+<p>
+Performance notice: <tt>ffi.copy()</tt> may be used as a faster
+(inlinable) replacement for the C&nbsp;library functions
+<tt>memcpy()</tt>, <tt>strcpy()</tt> and <tt>strncpy()</tt>.
+</p>
+
+<h3 id="ffi_fill"><tt>ffi.fill(dst, len [,c])</tt></h3>
+<p>
+Fills the data pointed to by <tt>dst</tt> with <tt>len</tt> constant
+bytes, given by <tt>c</tt>. If <tt>c</tt> is omitted, the data is
+zero-filled.
+</p>
+<p>
+Performance notice: <tt>ffi.fill()</tt> may be used as a faster
+(inlinable) replacement for the C&nbsp;library function
+<tt>memset(dst,&nbsp;c,&nbsp;len)</tt>. Please note the different
+order of arguments!
+</p>
+
+<h2 id="target">Target-specific Information</h2>
+
+<h3 id="ffi_abi"><tt>status = ffi.abi(param)</tt></h3>
+<p>
+Returns <tt>true</tt> if <tt>param</tt> (a Lua string) applies for the
+target ABI (Application Binary Interface). Returns <tt>false</tt>
+otherwise. The following parameters are currently defined:

+<h2 id="callback">Methods for Callbacks</h2>
+<p>
+The C&nbsp;types for <a href="ext_ffi_semantics.html#callback">callbacks</a>
+have some extra methods:
+</p>
+
+<h3 id="callback_free"><tt>cb:free()</tt></h3>
+<p>
+Free the resources associated with a callback. The associated Lua
+function is unanchored and may be garbage collected. The callback
+function pointer is no longer valid and must not be called anymore
+(it may be reused by a subsequently created callback).
+</p>
+
+<h3 id="callback_set"><tt>cb:set(func)</tt></h3>
+<p>
+Associate a new Lua function with a callback. The C&nbsp;type of the
+callback and the callback function pointer are unchanged.
+</p>
+<p>
+This method is useful to dynamically switch the receiver of callbacks
+without creating a new callback each time and registering it again (e.g.
+with a GUI library).
+</p>
+
+<h2 id="extended">Extended Standard Library Functions</h2>
+<p>
+The following standard library functions have been extended to work
+with cdata objects:
+</p>
+
+<h3 id="tonumber"><tt>n = tonumber(cdata)</tt></h3>
+<p>
+Converts a number cdata object to a <tt>double</tt> and returns it as
+a Lua number. This is particularly useful for boxed 64&nbsp;bit
+integer values. Caveat: this conversion may incur a precision loss.
+</p>
+
+<h3 id="tostring"><tt>s = tostring(cdata)</tt></h3>
+<p>
+Returns a string representation of the value of 64&nbsp;bit integers
+(<tt><b>"</b>nnn<b>LL"</b></tt> or <tt><b>"</b>nnn<b>ULL"</b></tt>) or
+complex numbers (<tt><b>"</b>re&plusmn;im<b>i"</b></tt>). Otherwise
+returns a string representation of the C&nbsp;type of a ctype object
+(<tt><b>"ctype&lt;</b>type<b>&gt;"</b></tt>) or a cdata object
+(<tt><b>"cdata&lt;</b>type<b>&gt;:&nbsp;</b>address"</tt>), unless you
+override it with a <tt>__tostring</tt> metamethod (see
+<a href="#ffi_metatype"><tt>ffi.metatype()</tt></a>).
+</p>
+
+<h3 id="pairs"><tt>iter, obj, start = pairs(cdata)<br>
+iter, obj, start = ipairs(cdata)<br></tt></h3>
+<p>
+Calls the <tt>__pairs</tt> or <tt>__ipairs</tt> metamethod of the
+corresponding ctype.
+</p>
+
+<h2 id="literals">Extensions to the Lua Parser</h2>
+<p>
+The parser for Lua source code treats numeric literals with the
+suffixes <tt>LL</tt> or <tt>ULL</tt> as signed or unsigned 64&nbsp;bit
+integers. Case doesn't matter, but uppercase is recommended for
+readability. It handles decimal (<tt>42LL</tt>), hexadecimal
+(<tt>0x2aLL</tt>) and binary (<tt>0b101010LL</tt>) literals.
+</p>
+<p>
+The imaginary part of complex numbers can be specified by suffixing
+number literals with <tt>i</tt> or <tt>I</tt>, e.g. <tt>12.5i</tt>.
+Caveat: you'll need to use <tt>1i</tt> to get an imaginary part with
+the value one, since <tt>i</tt> itself still refers to a variable
+named <tt>i</tt>.

+<p>
+This page describes the detailed semantics underlying the FFI library
+and its interaction with both Lua and C&nbsp;code.
+</p>
+<p>
+Given that the FFI library is designed to interface with C&nbsp;code
+and that declarations can be written in plain C&nbsp;syntax, <b>it
+closely follows the C&nbsp;language semantics</b>, wherever possible.
+Some minor concessions are needed for smoother interoperation with Lua
+language semantics.
+</p>
+<p>
+Please don't be overwhelmed by the contents of this page &mdash; this
+is a reference and you may need to consult it, if in doubt. It doesn't
+hurt to skim this page, but most of the semantics "just work" as you'd
+expect them to work. It should be straightforward to write
+applications using the LuaJIT FFI for developers with a C or C++
+background.
+</p>
+
+<h2 id="clang">C Language Support</h2>
+<p>
+The FFI library has a built-in C&nbsp;parser with a minimal memory
+footprint. It's used by the <a href="ext_ffi_api.html">ffi.* library
+functions</a> to declare C&nbsp;types or external symbols.
+</p>
+<p>
+It's only purpose is to parse C&nbsp;declarations, as found e.g. in
+C&nbsp;header files. Although it does evaluate constant expressions,
+it's <em>not</em> a C&nbsp;compiler. The body of <tt>inline</tt>
+C&nbsp;function definitions is simply ignored.
+</p>
+<p>
+Also, this is <em>not</em> a validating C&nbsp;parser. It expects and
+accepts correctly formed C&nbsp;declarations, but it may choose to
+ignore bad declarations or show rather generic error messages. If in
+doubt, please check the input against your favorite C&nbsp;compiler.
+</p>
+<p>
+The C&nbsp;parser complies to the <b>C99 language standard</b> plus
+the following extensions:
+</p>
+<ul>
+
+<li>The <tt>'\e'</tt> escape in character and string literals.</li>
+
+<li>The C99/C++ boolean type, declared with the keywords <tt>bool</tt>
+or <tt>_Bool</tt>.</li>
+
+<li>Complex numbers, declared with the keywords <tt>complex</tt> or
+<tt>_Complex</tt>.</li>
+
+<li>Two complex number types: <tt>complex</tt> (aka
+<tt>complex&nbsp;double</tt>) and <tt>complex&nbsp;float</tt>.</li>
+
+<li>Vector types, declared with the GCC <tt>mode</tt> or
+<tt>vector_size</tt> attribute.</li>
+
+<li>Unnamed ('transparent') <tt>struct</tt>/<tt>union</tt> fields
+inside a <tt>struct</tt>/<tt>union</tt>.</li>
+
+<li>Incomplete <tt>enum</tt> declarations, handled like incomplete
+<tt>struct</tt> declarations.</li>
+
+<li>Unnamed <tt>enum</tt> fields inside a
+<tt>struct</tt>/<tt>union</tt>. This is similar to a scoped C++
+<tt>enum</tt>, except that declared constants are visible in the
+global namespace, too.</li>
+
+<li>Scoped <tt>static&nbsp;const</tt> declarations inside a
+<tt>struct</tt>/<tt>union</tt> (from C++).</li>
+
+<li>Zero-length arrays (<tt>[0]</tt>), empty
+<tt>struct</tt>/<tt>union</tt>, variable-length arrays (VLA,
+<tt>[?]</tt>) and variable-length structs (VLS, with a trailing
+VLA).</li>
+
+<li>C++ reference types (<tt>int&nbsp;&amp;x</tt>).</li>
+
+<li>Alternate GCC keywords with '<tt>__</tt>', e.g.
+<tt>__const__</tt>.</li>
+
+<li>GCC <tt>__attribute__</tt> with the following attributes:
+<tt>aligned</tt>, <tt>packed</tt>, <tt>mode</tt>,
+<tt>vector_size</tt>, <tt>cdecl</tt>, <tt>fastcall</tt>,
+<tt>stdcall</tt>, <tt>thiscall</tt>.</li>
+
+<li>The GCC <tt>__extension__</tt> keyword and the GCC
+<tt>__alignof__</tt> operator.</li>
+
+<li>GCC <tt>__asm__("symname")</tt> symbol name redirection for
+function declarations.</li>
+
+<li>MSVC keywords for fixed-length types: <tt>__int8</tt>,
+<tt>__int16</tt>, <tt>__int32</tt> and <tt>__int64</tt>.</li>
+
+<li>MSVC <tt>__cdecl</tt>, <tt>__fastcall</tt>, <tt>__stdcall</tt>,
+<tt>__thiscall</tt>, <tt>__ptr32</tt>, <tt>__ptr64</tt>,
+<tt>__declspec(align(n))</tt> and <tt>#pragma&nbsp;pack</tt>.</li>
+
+<li>All other GCC/MSVC-specific attributes are ignored.</li>
+
+</ul>
+<p>
+The following C&nbsp;types are pre-defined by the C&nbsp;parser (like
+a <tt>typedef</tt>, except re-declarations will be ignored):
+</p>
+<ul>
+
+<li>Vararg handling: <tt>va_list</tt>, <tt>__builtin_va_list</tt>,
+<tt>__gnuc_va_list</tt>.</li>
+
+<li>From <tt>&lt;stddef.h&gt;</tt>: <tt>ptrdiff_t</tt>,
+<tt>size_t</tt>, <tt>wchar_t</tt>.</li>
+
+<li>From <tt>&lt;stdint.h&gt;</tt>: <tt>int8_t</tt>, <tt>int16_t</tt>,
+<tt>int32_t</tt>, <tt>int64_t</tt>, <tt>uint8_t</tt>,
+<tt>uint16_t</tt>, <tt>uint32_t</tt>, <tt>uint64_t</tt>,
+<tt>intptr_t</tt>, <tt>uintptr_t</tt>.</li>
+
+<li>From <tt>&lt;unistd.h&gt;</tt> (POSIX): <tt>ssize_t</tt>.</li>
+
+</ul>
+<p>
+You're encouraged to use these types in preference to
+compiler-specific extensions or target-dependent standard types.
+E.g. <tt>char</tt> differs in signedness and <tt>long</tt> differs in
+size, depending on the target architecture and platform ABI.
+</p>
+<p>
+The following C&nbsp;features are <b>not</b> supported:
+</p>
+<ul>
+
+<li>A declaration must always have a type specifier; it doesn't
+default to an <tt>int</tt> type.</li>
+
+<li>Old-style empty function declarations (K&amp;R) are not allowed.
+All C&nbsp;functions must have a proper prototype declaration. A
+function declared without parameters (<tt>int&nbsp;foo();</tt>) is
+treated as a function taking zero arguments, like in C++.</li>
+
+<li>The <tt>long double</tt> C&nbsp;type is parsed correctly, but
+there's no support for the related conversions, accesses or arithmetic
+operations.</li>
+
+<li>Wide character strings and character literals are not
+supported.</li>
+
+<li><a href="#status">See below</a> for features that are currently
+not implemented.</li>

+To pass a Lua object, other than a cdata object, as a specific type,
+you need to override the conversion rules: create a temporary cdata
+object with a constructor or a cast and initialize it with the value
+to pass:
+</p>
+<p>
+Assuming <tt>x</tt> is a Lua number, here's how to pass it as an
+integer to a vararg function:
+</p>
+<pre class="code">
+ffi.cdef[[
+int printf(const char *fmt, ...);
+]]
+ffi.C.printf("integer value: %d\n", ffi.new("int", x))
+</pre>
+<p>
+If you don't do this, the default Lua number &rarr; <tt>double</tt>
+conversion rule applies. A vararg C&nbsp;function expecting an integer
+will see a garbled or uninitialized value.
+</p>
+
+<h2 id="init">Initializers</h2>
+<p>
+Creating a cdata object with
+<a href="ext_ffi_api.html#ffi_new"><tt>ffi.new()</tt></a> or the
+equivalent constructor syntax always initializes its contents, too.
+Different rules apply, depending on the number of optional
+initializers and the C&nbsp;types involved:
+</p>
+<ul>
+<li>If no initializers are given, the object is filled with zero bytes.</li>
+
+<li>Scalar types (numbers and pointers) accept a single initializer.
+The Lua object is <a href="#convert_fromlua">converted to the scalar
+C&nbsp;type</a>.</li>
+
+<li>Valarrays (complex numbers and vectors) are treated like scalars
+when a single initializer is given. Otherwise they are treated like
+regular arrays.</li>
+
+<li>Aggregate types (arrays and structs) accept either a single cdata
+initializer of the same type (copy constructor), a single
+<a href="#init_table">table initializer</a>, or a flat list of
+initializers.</li>
+
+<li>The elements of an array are initialized, starting at index zero.
+If a single initializer is given for an array, it's repeated for all
+remaining elements. This doesn't happen if two or more initializers
+are given: all remaining uninitialized elements are filled with zero
+bytes.</li>
+
+<li>Byte arrays may also be initialized with a Lua string. This copies
+the whole string plus a terminating zero-byte. The copy stops early only
+if the array has a known, fixed size.</li>
+
+<li>The fields of a <tt>struct</tt> are initialized in the order of
+their declaration. Uninitialized fields are filled with zero
+bytes.</li>
+
+<li>Only the first field of a <tt>union</tt> can be initialized with a
+flat initializer.</li>
+
+<li>Elements or fields which are aggregates themselves are initialized
+with a <em>single</em> initializer, but this may be a table
+initializer or a compatible aggregate.</li>
+
+<li>Excess initializers cause an error.</li>
+
+</ul>
+
+<h2 id="init_table">Table Initializers</h2>
+<p>
+The following rules apply if a Lua table is used to initialize an
+Array or a <tt>struct</tt>/<tt>union</tt>:
+</p>
+<ul>
+
+<li>If the table index <tt>[0]</tt> is non-<tt>nil</tt>, then the
+table is assumed to be zero-based. Otherwise it's assumed to be
+one-based.</li>
+
+<li>Array elements, starting at index zero, are initialized one-by-one
+with the consecutive table elements, starting at either index
+<tt>[0]</tt> or <tt>[1]</tt>. This process stops at the first
+<tt>nil</tt> table element.</li>
+
+<li>If exactly one array element was initialized, it's repeated for
+all the remaining elements. Otherwise all remaining uninitialized
+elements are filled with zero bytes.</li>
+
+<li>The above logic only applies to arrays with a known fixed size.
+A VLA is only initialized with the element(s) given in the table.
+Depending on the use case, you may need to explicitly add a
+<tt>NULL</tt> or <tt>0</tt> terminator to a VLA.</li>
+
+<li>A <tt>struct</tt>/<tt>union</tt> can be initialized in the
+order of the declaration of its fields. Each field is initialized with
+consecutive table elements, starting at either index <tt>[0]</tt>
+or <tt>[1]</tt>. This process stops at the first <tt>nil</tt> table
+element.</li>
+
+<li>Otherwise, if neither index <tt>[0]</tt> nor <tt>[1]</tt> is present,
+a <tt>struct</tt>/<tt>union</tt> is initialized by looking up each field
+name (as a string key) in the table. Each non-<tt>nil</tt> value is
+used to initialize the corresponding field.</li>
+
+<li>Uninitialized fields of a <tt>struct</tt> are filled with zero
+bytes, except for the trailing VLA of a VLS.</li>
+
+<li>Initialization of a <tt>union</tt> stops after one field has been
+initialized. If no field has been initialized, the <tt>union</tt> is
+filled with zero bytes.</li>
+
+<li>Elements or fields which are aggregates themselves are initialized
+with a <em>single</em> initializer, but this may be a nested table
+initializer (or a compatible aggregate).</li>
+
+<li>Excess initializers for an array cause an error. Excess
+initializers for a <tt>struct</tt>/<tt>union</tt> are ignored.
+Unrelated table entries are ignored, too.</li>
+
+</ul>

+<h2 id="cdata_ops">Operations on cdata Objects</h2>
+<p>
+All of the standard Lua operators can be applied to cdata objects or a
+mix of a cdata object and another Lua object. The following list shows
+the pre-defined operations.
+</p>
+<p>
+Reference types are dereferenced <em>before</em> performing each of
+the operations below &mdash; the operation is applied to the
+C&nbsp;type pointed to by the reference.
+</p>
+<p>
+The pre-defined operations are always tried first before deferring to a
+metamethod or index table (if any) for the corresponding ctype (except
+for <tt>__new</tt>). An error is raised if the metamethod lookup or
+index table lookup fails.
+</p>
+
+<h3 id="cdata_array">Indexing a cdata object</h3>
+<ul>
+
+<li><b>Indexing a pointer/array</b>: a cdata pointer/array can be
+indexed by a cdata number or a Lua number. The element address is
+computed as the base address plus the number value multiplied by the
+element size in bytes. A read access loads the element value and
+<a href="#convert_tolua">converts it to a Lua object</a>. A write
+access <a href="#convert_fromlua">converts a Lua object to the element
+type</a> and stores the converted value to the element. An error is
+raised if the element size is undefined or a write access to a
+constant element is attempted.</li>
+
+<li><b>Dereferencing a <tt>struct</tt>/<tt>union</tt> field</b>: a
+cdata <tt>struct</tt>/<tt>union</tt> or a pointer to a
+<tt>struct</tt>/<tt>union</tt> can be dereferenced by a string key,
+giving the field name. The field address is computed as the base
+address plus the relative offset of the field. A read access loads the
+field value and <a href="#convert_tolua">converts it to a Lua
+object</a>. A write access <a href="#convert_fromlua">converts a Lua
+object to the field type</a> and stores the converted value to the
+field. An error is raised if a write access to a constant
+<tt>struct</tt>/<tt>union</tt> or a constant field is attempted.
+Scoped enum constants or static constants are treated like a constant
+field.</li>
+
+<li><b>Indexing a complex number</b>: a complex number can be indexed
+either by a cdata number or a Lua number with the values 0 or 1, or by
+the strings <tt>"re"</tt> or <tt>"im"</tt>. A read access loads the
+real part (<tt>[0]</tt>, <tt>.re</tt>) or the imaginary part
+(<tt>[1]</tt>, <tt>.im</tt>) part of a complex number and
+<a href="#convert_tolua">converts it to a Lua number</a>. The
+sub-parts of a complex number are immutable &mdash; assigning to an
+index of a complex number raises an error. Accessing out-of-bound
+indexes returns unspecified results, but is guaranteed not to trigger
+memory access violations.</li>
+
+<li><b>Indexing a vector</b>: a vector is treated like an array for
+indexing purposes, except the vector elements are immutable &mdash;
+assigning to an index of a vector raises an error.</li>
+
+</ul>
+<p>
+A ctype object can be indexed with a string key, too. The only
+pre-defined operation is reading scoped constants of
+<tt>struct</tt>/<tt>union</tt> types. All other accesses defer
+to the corresponding metamethods or index tables (if any).
+</p>
+<p>
+Note: since there's (deliberately) no address-of operator, a cdata
+object holding a value type is effectively immutable after
+initialization. The JIT compiler benefits from this fact when applying
+certain optimizations.
+</p>
+<p>
+As a consequence, the <em>elements</em> of complex numbers and
+vectors are immutable. But the elements of an aggregate holding these
+types <em>may</em> be modified of course. I.e. you cannot assign to
+<tt>foo.c.im</tt>, but you can assign a (newly created) complex number
+to <tt>foo.c</tt>.
+</p>
+<p>
+The JIT compiler implements strict aliasing rules: accesses to different
+types do <b>not</b> alias, except for differences in signedness (this
+applies even to <tt>char</tt> pointers, unlike C99). Type punning
+through unions is explicitly detected and allowed.
+</p>
+
+<h3 id="cdata_call">Calling a cdata object</h3>
+<ul>
+
+<li><b>Constructor</b>: a ctype object can be called and used as a
+<a href="ext_ffi_api.html#ffi_new">constructor</a>. This is equivalent
+to <tt>ffi.new(ct, ...)</tt>, unless a <tt>__new</tt> metamethod is
+defined. The <tt>__new</tt> metamethod is called with the ctype object
+plus any other arguments passed to the contructor. Note that you have to
+use <tt>ffi.new</tt> inside of it, since calling <tt>ct(...)</tt> would
+cause infinite recursion.</li>
+
+<li><b>C&nbsp;function call</b>: a cdata function or cdata function
+pointer can be called. The passed arguments are
+<a href="#convert_fromlua">converted to the C&nbsp;types</a> of the
+parameters given by the function declaration. Arguments passed to the
+variable argument part of vararg C&nbsp;function use
+<a href="#convert_vararg">special conversion rules</a>. This
+C&nbsp;function is called and the return value (if any) is
+<a href="#convert_tolua">converted to a Lua object</a>.<br>
+On Windows/x86 systems, <tt>__stdcall</tt> functions are automatically
+detected and a function declared as <tt>__cdecl</tt> (the default) is
+silently fixed up after the first call.</li>
+
+</ul>
+
+<h3 id="cdata_arith">Arithmetic on cdata objects</h3>
+<ul>
+
+<li><b>Pointer arithmetic</b>: a cdata pointer/array and a cdata
+number or a Lua number can be added or subtracted. The number must be
+on the right hand side for a subtraction. The result is a pointer of
+the same type with an address plus or minus the number value
+multiplied by the element size in bytes. An error is raised if the
+element size is undefined.</li>
+
+<li><b>Pointer difference</b>: two compatible cdata pointers/arrays
+can be subtracted. The result is the difference between their
+addresses, divided by the element size in bytes. An error is raised if
+the element size is undefined or zero.</li>
+
+<li><b>64&nbsp;bit integer arithmetic</b>: the standard arithmetic
+operators (<tt>+&nbsp;-&nbsp;*&nbsp;/&nbsp;%&nbsp;^</tt> and unary
+minus) can be applied to two cdata numbers, or a cdata number and a
+Lua number. If one of them is an <tt>uint64_t</tt>, the other side is
+converted to an <tt>uint64_t</tt> and an unsigned arithmetic operation
+is performed. Otherwise both sides are converted to an
+<tt>int64_t</tt> and a signed arithmetic operation is performed. The
+result is a boxed 64&nbsp;bit cdata object.<br>
+
+If one of the operands is an <tt>enum</tt> and the other operand is a
+string, the string is converted to the value of a matching <tt>enum</tt>
+constant before the above conversion.<br>
+
+These rules ensure that 64&nbsp;bit integers are "sticky". Any
+expression involving at least one 64&nbsp;bit integer operand results
+in another one. The undefined cases for the division, modulo and power
+operators return <tt>2LL&nbsp;^&nbsp;63</tt> or
+<tt>2ULL&nbsp;^&nbsp;63</tt>.<br>
+
+You'll have to explicitly convert a 64&nbsp;bit integer to a Lua
+number (e.g. for regular floating-point calculations) with
+<tt>tonumber()</tt>. But note this may incur a precision loss.</li>
+
+<li><b>64&nbsp;bit bitwise operations</b>: the rules for 64&nbsp;bit
+arithmetic operators apply analogously.<br>
+
+Unlike the other <tt>bit.*</tt> operations, <tt>bit.tobit()</tt>
+converts a cdata number via <tt>int64_t</tt> to <tt>int32_t</tt> and
+returns a Lua number.<br>
+
+For <tt>bit.band()</tt>, <tt>bit.bor()</tt> and <tt>bit.bxor()</tt>, the
+conversion to <tt>int64_t</tt> or <tt>uint64_t</tt> applies to
+<em>all</em> arguments, if <em>any</em> argument is a cdata number.<br>
+
+For all other operations, only the first argument is used to determine
+the output type. This implies that a cdata number as a shift count for
+shifts and rotates is accepted, but that alone does <em>not</em> cause
+a cdata number output.
+
+</ul>
+
+<h3 id="cdata_comp">Comparisons of cdata objects</h3>
+<ul>
+
+<li><b>Pointer comparison</b>: two compatible cdata pointers/arrays
+can be compared. The result is the same as an unsigned comparison of
+their addresses. <tt>nil</tt> is treated like a <tt>NULL</tt> pointer,
+which is compatible with any other pointer type.</li>
+
+<li><b>64&nbsp;bit integer comparison</b>: two cdata numbers, or a
+cdata number and a Lua number can be compared with each other. If one
+of them is an <tt>uint64_t</tt>, the other side is converted to an
+<tt>uint64_t</tt> and an unsigned comparison is performed. Otherwise
+both sides are converted to an <tt>int64_t</tt> and a signed
+comparison is performed.<br>
+
+If one of the operands is an <tt>enum</tt> and the other operand is a
+string, the string is converted to the value of a matching <tt>enum</tt>
+constant before the above conversion.<br>
+
+<li><b>Comparisons for equality/inequality</b> never raise an error.
+Even incompatible pointers can be compared for equality by address. Any
+other incompatible comparison (also with non-cdata objects) treats the
+two sides as unequal.</li>
+
+</ul>
+
+<h3 id="cdata_key">cdata objects as table keys</h3>
+<p>
+Lua tables may be indexed by cdata objects, but this doesn't provide
+any useful semantics &mdash; <b>cdata objects are unsuitable as table
+keys!</b>
+</p>
+<p>
+A cdata object is treated like any other garbage-collected object and
+is hashed and compared by its address for table indexing. Since
+there's no interning for cdata value types, the same value may be
+boxed in different cdata objects with different addresses. Thus
+<tt>t[1LL+1LL]</tt> and <tt>t[2LL]</tt> usually <b>do not</b> point to
+the same hash slot and they certainly <b>do not</b> point to the same
+hash slot as <tt>t[2]</tt>.
+</p>
+<p>
+It would seriously drive up implementation complexity and slow down
+the common case, if one were to add extra handling for by-value
+hashing and comparisons to Lua tables. Given the ubiquity of their use
+inside the VM, this is not acceptable.
+</p>
+<p>
+There are three viable alternatives, if you really need to use cdata
+objects as keys:
+</p>
+<ul>
+
+<li>If you can get by with the precision of Lua numbers
+(52&nbsp;bits), then use <tt>tonumber()</tt> on a cdata number or
+combine multiple fields of a cdata aggregate to a Lua number. Then use
+the resulting Lua number as a key when indexing tables.<br>
+One obvious benefit: <tt>t[tonumber(2LL)]</tt> <b>does</b> point to
+the same slot as <tt>t[2]</tt>.</li>
+
+<li>Otherwise use either <tt>tostring()</tt> on 64&nbsp;bit integers
+or complex numbers or combine multiple fields of a cdata aggregate to
+a Lua string (e.g. with
+<a href="ext_ffi_api.html#ffi_string"><tt>ffi.string()</tt></a>). Then
+use the resulting Lua string as a key when indexing tables.</li>
+
+<li>Create your own specialized hash table implementation using the
+C&nbsp;types provided by the FFI library, just like you would in
+C&nbsp;code. Ultimately this may give much better performance than the
+other alternatives or what a generic by-value hash table could
+possibly provide.</li>
+
+</ul>
+
+<h2 id="param">Parameterized Types</h2>
+<p>
+To facilitate some abstractions, the two functions
+<a href="ext_ffi_api.html#ffi_typeof"><tt>ffi.typeof</tt></a> and
+<a href="ext_ffi_api.html#ffi_cdef"><tt>ffi.cdef</tt></a> support
+parameterized types in C&nbsp;declarations. Note: none of the other API
+functions taking a cdecl allow this.
+</p>
+<p>
+Any place you can write a <b><tt>typedef</tt> name</b>, an
+<b>identifier</b> or a <b>number</b> in a declaration, you can write
+<tt>$</tt> (the dollar sign) instead. These placeholders are replaced in
+order of appearance with the arguments following the cdecl string:
+</p>
+<pre class="code">
+-- Declare a struct with a parameterized field type and name:
+ffi.cdef([[
+typedef struct { $ $; } foo_t;
+]], type1, name1)
+
+-- Anonymous struct with dynamic names:
+local bar_t = ffi.typeof("struct { int $, $; }", name1, name2)
+-- Derived pointer type:
+local bar_ptr_t = ffi.typeof("$ *", bar_t)
+
+-- Parameterized dimensions work even where a VLA won't work:
+local matrix_t = ffi.typeof("uint8_t[$][$]", width, height)
+</pre>
+<p>
+Caveat: this is <em>not</em> simple text substitution! A passed ctype or
+cdata object is treated like the underlying type, a passed string is
+considered an identifier and a number is considered a number. You must
+not mix this up: e.g. passing <tt>"int"</tt> as a string doesn't work in
+place of a type, you'd need to use <tt>ffi.typeof("int")</tt> instead.
+</p>
+<p>
+The main use for parameterized types are libraries implementing abstract
+data types
+(<a href="https://www.freelists.org/post/luajit/ffi-type-of-pointer-to,8">example</a>),
+similar to what can be achieved with C++ template metaprogramming.
+Another use case are derived types of anonymous structs, which avoids
+pollution of the global struct namespace.
+</p>
+<p>
+Please note that parameterized types are a nice tool and indispensable
+for certain use cases. But you'll want to use them sparingly in regular
+code, e.g. when all types are actually fixed.
+</p>
+
+<h2 id="gc">Garbage Collection of cdata Objects</h2>
+<p>
+All explicitly (<tt>ffi.new()</tt>, <tt>ffi.cast()</tt> etc.) or
+implicitly (accessors) created cdata objects are garbage collected.
+You need to ensure to retain valid references to cdata objects
+somewhere on a Lua stack, an upvalue or in a Lua table while they are
+still in use. Once the last reference to a cdata object is gone, the
+garbage collector will automatically free the memory used by it (at
+the end of the next GC cycle).
+</p>
+<p>
+Please note that pointers themselves are cdata objects, however they
+are <b>not</b> followed by the garbage collector. So e.g. if you
+assign a cdata array to a pointer, you must keep the cdata object
+holding the array alive as long as the pointer is still in use:
+</p>
+<pre class="code">
+ffi.cdef[[
+typedef struct { int *a; } foo_t;
+]]
+
+local s = ffi.new("foo_t", ffi.new("int[10]")) -- <span style="color:#c00000;">WRONG!</span>
+
+local a = ffi.new("int[10]") -- <span style="color:#00a000;">OK</span>
+local s = ffi.new("foo_t", a)
+-- Now do something with 's', but keep 'a' alive until you're done.
+</pre>
+<p>
+Similar rules apply for Lua strings which are implicitly converted to
+<tt>"const&nbsp;char&nbsp;*"</tt>: the string object itself must be
+referenced somewhere or it'll be garbage collected eventually. The
+pointer will then point to stale data, which may have already been
+overwritten. Note that <em>string literals</em> are automatically kept
+alive as long as the function containing it (actually its prototype)
+is not garbage collected.
+</p>
+<p>
+Objects which are passed as an argument to an external C&nbsp;function
+are kept alive until the call returns. So it's generally safe to
+create temporary cdata objects in argument lists. This is a common
+idiom for <a href="#convert_vararg">passing specific C&nbsp;types to
+vararg functions</a>.
+</p>
+<p>
+Memory areas returned by C functions (e.g. from <tt>malloc()</tt>)
+must be manually managed, of course (or use
+<a href="ext_ffi_api.html#ffi_gc"><tt>ffi.gc()</tt></a>). Pointers to
+cdata objects are indistinguishable from pointers returned by C
+functions (which is one of the reasons why the GC cannot follow them).
+</p>
+
+<h2 id="callback">Callbacks</h2>
+<p>
+The LuaJIT FFI automatically generates special callback functions
+whenever a Lua function is converted to a C&nbsp;function pointer. This
+associates the generated callback function pointer with the C&nbsp;type
+of the function pointer and the Lua function object (closure).
+</p>
+<p>
+This can happen implicitly due to the usual conversions, e.g. when
+passing a Lua function to a function pointer argument. Or you can use
+<tt>ffi.cast()</tt> to explicitly cast a Lua function to a
+C&nbsp;function pointer.
+</p>
+<p>
+Currently only certain C&nbsp;function types can be used as callback
+functions. Neither C&nbsp;vararg functions nor functions with
+pass-by-value aggregate argument or result types are supported. There
+are no restrictions for the kind of Lua functions that can be called
+from the callback &mdash; no checks for the proper number of arguments
+are made. The return value of the Lua function will be converted to the
+result type and an error will be thrown for invalid conversions.
+</p>
+<p>
+It's allowed to throw errors across a callback invocation, but it's not
+advisable in general. Do this only if you know the C&nbsp;function, that
+called the callback, copes with the forced stack unwinding and doesn't
+leak resources.
+</p>
+<p>
+One thing that's not allowed, is to let an FFI call into a C&nbsp;function
+get JIT-compiled, which in turn calls a callback, calling into Lua again.
+Usually this attempt is caught by the interpreter first and the
+C&nbsp;function is blacklisted for compilation.
+</p>
+<p>
+However, this heuristic may fail under specific circumstances: e.g. a
+message polling function might not run Lua callbacks right away and the call
+gets JIT-compiled. If it later happens to call back into Lua (e.g. a rarely
+invoked error callback), you'll get a VM PANIC with the message
+<tt>"bad callback"</tt>. Then you'll need to manually turn off
+JIT-compilation with
+<a href="ext_jit.html#jit_onoff_func"><tt>jit.off()</tt></a> for the
+surrounding Lua function that invokes such a message polling function (or
+similar).
+</p>
+
+<h3 id="callback_resources">Callback resource handling</h3>
+<p>
+Callbacks take up resources &mdash; you can only have a limited number
+of them at the same time (500&nbsp;-&nbsp;1000, depending on the
+architecture). The associated Lua functions are anchored to prevent
+garbage collection, too.
+</p>
+<p>
+<b>Callbacks due to implicit conversions are permanent!</b> There is no
+way to guess their lifetime, since the C&nbsp;side might store the
+function pointer for later use (typical for GUI toolkits). The associated
+resources cannot be reclaimed until termination:
+</p>
+<pre class="code">
+ffi.cdef[[
+typedef int (__stdcall *WNDENUMPROC)(void *hwnd, intptr_t l);
+int EnumWindows(WNDENUMPROC func, intptr_t l);
+]]
+
+-- Implicit conversion to a callback via function pointer argument.
+local count = 0
+ffi.C.EnumWindows(function(hwnd, l)
+  count = count + 1
+  return true
+end, 0)
+-- The callback is permanent and its resources cannot be reclaimed!
+-- Ok, so this may not be a problem, if you do this only once.
+</pre>
+<p>
+Note: this example shows that you <em>must</em> properly declare
+<tt>__stdcall</tt> callbacks on Windows/x86 systems. The calling
+convention cannot be automatically detected, unlike for
+<tt>__stdcall</tt> calls <em>to</em> Windows functions.
+</p>
+<p>
+For some use cases it's necessary to free up the resources or to
+dynamically redirect callbacks. Use an explicit cast to a
+C&nbsp;function pointer and keep the resulting cdata object. Then use
+the <a href="ext_ffi_api.html#callback_free"><tt>cb:free()</tt></a>
+or <a href="ext_ffi_api.html#callback_set"><tt>cb:set()</tt></a> methods
+on the cdata object:
+</p>
+<pre class="code">
+-- Explicitly convert to a callback via cast.
+local count = 0
+local cb = ffi.cast("WNDENUMPROC", function(hwnd, l)
+  count = count + 1
+  return true
+end)
+
+-- Pass it to a C function.
+ffi.C.EnumWindows(cb, 0)
+-- EnumWindows doesn't need the callback after it returns, so free it.
+
+cb:free()
+-- The callback function pointer is no longer valid and its resources
+-- will be reclaimed. The created Lua closure will be garbage collected.
+</pre>
+
+<h3 id="callback_performance">Callback performance</h3>
+<p>
+<b>Callbacks are slow!</b> First, the C&nbsp;to Lua transition itself
+has an unavoidable cost, similar to a <tt>lua_call()</tt> or
+<tt>lua_pcall()</tt>. Argument and result marshalling add to that cost.
+And finally, neither the C&nbsp;compiler nor LuaJIT can inline or
+optimize across the language barrier and hoist repeated computations out
+of a callback function.
+</p>
+<p>
+Do not use callbacks for performance-sensitive work: e.g. consider a
+numerical integration routine which takes a user-defined function to
+integrate over. It's a bad idea to call a user-defined Lua function from
+C&nbsp;code millions of times. The callback overhead will be absolutely
+detrimental for performance.
+</p>
+<p>
+It's considerably faster to write the numerical integration routine
+itself in Lua &mdash; the JIT compiler will be able to inline the
+user-defined function and optimize it together with its calling context,
+with very competitive performance.
+</p>
+<p>
+As a general guideline: <b>use callbacks only when you must</b>, because
+of existing C&nbsp;APIs. E.g. callback performance is irrelevant for a
+GUI application, which waits for user input most of the time, anyway.
+</p>
+<p>
+For new designs <b>avoid push-style APIs</b>: a C&nbsp;function repeatedly
+calling a callback for each result. Instead <b>use pull-style APIs</b>:
+call a C&nbsp;function repeatedly to get a new result. Calls from Lua
+to C via the FFI are much faster than the other way round. Most well-designed
+libraries already use pull-style APIs (read/write, get/put).
+</p>
+
+<h2 id="clib">C Library Namespaces</h2>
+<p>
+A C&nbsp;library namespace is a special kind of object which allows
+access to the symbols contained in shared libraries or the default
+symbol namespace. The default
+<a href="ext_ffi_api.html#ffi_C"><tt>ffi.C</tt></a> namespace is
+automatically created when the FFI library is loaded. C&nbsp;library
+namespaces for specific shared libraries may be created with the
+<a href="ext_ffi_api.html#ffi_load"><tt>ffi.load()</tt></a> API
+function.
+</p>
+<p>
+Indexing a C&nbsp;library namespace object with a symbol name (a Lua
+string) automatically binds it to the library. First the symbol type
+is resolved &mdash; it must have been declared with
+<a href="ext_ffi_api.html#ffi_cdef"><tt>ffi.cdef</tt></a>. Then the
+symbol address is resolved by searching for the symbol name in the
+associated shared libraries or the default symbol namespace. Finally,
+the resulting binding between the symbol name, the symbol type and its
+address is cached. Missing symbol declarations or nonexistent symbol
+names cause an error.
+</p>
+<p>
+This is what happens on a <b>read access</b> for the different kinds of
+symbols:
+</p>
+<ul>
+
+<li>External functions: a cdata object with the type of the function
+and its address is returned.</li>
+
+<li>External variables: the symbol address is dereferenced and the
+loaded value is <a href="#convert_tolua">converted to a Lua object</a>
+and returned.</li>
+
+<li>Constant values (<tt>static&nbsp;const</tt> or <tt>enum</tt>
+constants): the constant is <a href="#convert_tolua">converted to a
+Lua object</a> and returned.</li>
+
+</ul>
+<p>
+This is what happens on a <b>write access</b>:
+</p>
+<ul>
+
+<li>External variables: the value to be written is
+<a href="#convert_fromlua">converted to the C&nbsp;type</a> of the
+variable and then stored at the symbol address.</li>
+
+<li>Writing to constant variables or to any other symbol type causes
+an error, like any other attempted write to a constant location.</li>
+
+</ul>
+<p>
+C&nbsp;library namespaces themselves are garbage collected objects. If
+the last reference to the namespace object is gone, the garbage
+collector will eventually release the shared library reference and
+remove all memory associated with the namespace. Since this may
+trigger the removal of the shared library from the memory of the
+running process, it's generally <em>not safe</em> to use function
+cdata objects obtained from a library if the namespace object may be
+unreferenced.
+</p>
+<p>
+Performance notice: the JIT compiler specializes to the identity of
+namespace objects and to the strings used to index it. This
+effectively turns function cdata objects into constants. It's not
+useful and actually counter-productive to explicitly cache these
+function objects, e.g. <tt>local strlen = ffi.C.strlen</tt>. OTOH it
+<em>is</em> useful to cache the namespace itself, e.g. <tt>local C =
+ffi.C</tt>.
+</p>
+
+<h2 id="policy">No Hand-holding!</h2>
+<p>
+The FFI library has been designed as <b>a low-level library</b>. The
+goal is to interface with C&nbsp;code and C&nbsp;data types with a
+minimum of overhead. This means <b>you can do anything you can do
+from&nbsp;C</b>: access all memory, overwrite anything in memory, call
+machine code at any memory address and so on.
+</p>
+<p>
+The FFI library provides <b>no memory safety</b>, unlike regular Lua
+code. It will happily allow you to dereference a <tt>NULL</tt>
+pointer, to access arrays out of bounds or to misdeclare
+C&nbsp;functions. If you make a mistake, your application might crash,
+just like equivalent C&nbsp;code would.
+</p>
+<p>
+This behavior is inevitable, since the goal is to provide full
+interoperability with C&nbsp;code. Adding extra safety measures, like
+bounds checks, would be futile. There's no way to detect
+misdeclarations of C&nbsp;functions, since shared libraries only
+provide symbol names, but no type information. Likewise there's no way
+to infer the valid range of indexes for a returned pointer.
+</p>
+<p>
+Again: the FFI library is a low-level library. This implies it needs
+to be used with care, but it's flexibility and performance often
+outweigh this concern. If you're a C or C++ developer, it'll be easy
+to apply your existing knowledge. OTOH writing code for the FFI
+library is not for the faint of heart and probably shouldn't be the
+first exercise for someone with little experience in Lua, C or C++.
+</p>
+<p>
+As a corollary of the above, the FFI library is <b>not safe for use by
+untrusted Lua code</b>. If you're sandboxing untrusted Lua code, you
+definitely don't want to give this code access to the FFI library or
+to <em>any</em> cdata object (except 64&nbsp;bit integers or complex
+numbers). Any properly engineered Lua sandbox needs to provide safety
+wrappers for many of the standard Lua library functions &mdash;
+similar wrappers need to be written for high-level operations on FFI
+data types, too.
+</p>
+
+<h2 id="status">Current Status</h2>
+<p>
+The initial release of the FFI library has some limitations and is
+missing some features. Most of these will be fixed in future releases.
+</p>
+<p>
+<a href="#clang">C language support</a> is
+currently incomplete:
+</p>
+<ul>
+<li>C&nbsp;declarations are not passed through a C&nbsp;pre-processor,
+yet.</li>
+<li>The C&nbsp;parser is able to evaluate most constant expressions
+commonly found in C&nbsp;header files. However it doesn't handle the
+full range of C&nbsp;expression semantics and may fail for some
+obscure constructs.</li>
+<li><tt>static const</tt> declarations only work for integer types
+up to 32&nbsp;bits. Neither declaring string constants nor
+floating-point constants is supported.</li>
+<li>Packed <tt>struct</tt> bitfields that cross container boundaries
+are not implemented.</li>
+<li>Native vector types may be defined with the GCC <tt>mode</tt> or
+<tt>vector_size</tt> attribute. But no operations other than loading,
+storing and initializing them are supported, yet.</li>
+<li>The <tt>volatile</tt> type qualifier is currently ignored by
+compiled code.</li>
+<li><a href="ext_ffi_api.html#ffi_cdef"><tt>ffi.cdef</tt></a> silently
+ignores most re-declarations. Note: avoid re-declarations which do not
+conform to C99. The implementation will eventually be changed to
+perform strict checks.</li>
+</ul>
+<p>
+The JIT compiler already handles a large subset of all FFI operations.
+It automatically falls back to the interpreter for unimplemented
+operations (you can check for this with the
+<a href="running.html#opt_j"><tt>-jv</tt></a> command line option).
+The following operations are currently not compiled and may exhibit
+suboptimal performance, especially when used in inner loops:
+</p>
+<ul>
+<li>Vector operations.</li>
+<li>Table initializers.</li>
+<li>Initialization of nested <tt>struct</tt>/<tt>union</tt> types.</li>
+<li>Non-default initialization of VLA/VLS or large C&nbsp;types
+(&gt; 128&nbsp;bytes or &gt; 16 array elements.</li>
+<li>Bitfield initializations.</li>
+<li>Pointer differences for element sizes that are not a power of
+two.</li>
+<li>Calls to C&nbsp;functions with aggregates passed or returned by
+value.</li>
+<li>Calls to ctype metamethods which are not plain functions.</li>
+<li>ctype <tt>__newindex</tt> tables and non-string lookups in ctype
+<tt>__index</tt> tables.</li>
+<li><tt>tostring()</tt> for cdata types.</li>
+<li>Calls to <tt>ffi.cdef()</tt>, <tt>ffi.load()</tt> and
+<tt>ffi.metatype()</tt>.</li>
+</ul>
+<p>
+Other missing features:
+</p>
+<ul>
+<li>Arithmetic for <tt>complex</tt> numbers.</li>
+<li>Passing structs by value to vararg C&nbsp;functions.</li>

+This page is intended to give you an overview of the features of the FFI
+library by presenting a few use cases and guidelines.
+</p>
+<p>
+This page makes no attempt to explain all of the FFI library, though.
+You'll want to have a look at the <a href="ext_ffi_api.html">ffi.* API
+function reference</a> and the <a href="ext_ffi_semantics.html">FFI
+semantics</a> to learn more.
+</p>
+
+<h2 id="load">Loading the FFI Library</h2>
+<p>
+The FFI library is built into LuaJIT by default, but it's not loaded
+and initialized by default. The suggested way to use the FFI library
+is to add the following to the start of every Lua file that needs one
+of its functions:
+</p>
+<pre class="code">
+local ffi = require("ffi")
+</pre>
+<p>
+Please note this doesn't define an <tt>ffi</tt> variable in the table
+of globals &mdash; you really need to use the local variable. The
+<tt>require</tt> function ensures the library is only loaded once.
+</p>
+<p style="font-size: 8pt;">
+Note: If you want to experiment with the FFI from the interactive prompt
+of the command line executable, omit the <tt>local</tt>, as it doesn't
+preserve local variables across lines.
+</p>
+
+<h2 id="sleep">Accessing Standard System Functions</h2>
+<p>
+The following code explains how to access standard system functions.
+We slowly print two lines of dots by sleeping for 10&nbsp;milliseconds
+after each dot:
+</p>
+<pre class="code mark">
+<span class="codemark">&nbsp;

+

+&#9313;
+&#9314;
+&#9315;
+
+
+
+&#9316;
+
+
+
+
+
+&#9317;</span>local ffi = require("ffi")
+ffi.cdef[[
+<span style="color:#00a000;">void Sleep(int ms);
+int poll(struct pollfd *fds, unsigned long nfds, int timeout);</span>
+]]
+
+local sleep
+if ffi.os == "Windows" then
+  function sleep(s)
+    ffi.C.Sleep(s*1000)
+  end
+else
+  function sleep(s)
+    ffi.C.poll(nil, 0, s*1000)
+  end
+end
+
+for i=1,160 do
+  io.write("."); io.flush()
+  sleep(0.01)
+end
+io.write("\n")
+</pre>
+<p>
+Here's the step-by-step explanation:
+</p>
+<p>
+<span class="mark">&#9312;</span> This defines the
+C&nbsp;library functions we're going to use. The part inside the
+double-brackets (in green) is just standard C&nbsp;syntax. You can
+usually get this info from the C&nbsp;header files or the
+documentation provided by each C&nbsp;library or C&nbsp;compiler.
+</p>
+<p>
+<span class="mark">&#9313;</span> The difficulty we're
+facing here, is that there are different standards to choose from.
+Windows has a simple <tt>Sleep()</tt> function. On other systems there
+are a variety of functions available to achieve sub-second sleeps, but
+with no clear consensus. Thankfully <tt>poll()</tt> can be used for
+this task, too, and it's present on most non-Windows systems. The
+check for <tt>ffi.os</tt> makes sure we use the Windows-specific
+function only on Windows systems.
+</p>
+<p>
+<span class="mark">&#9314;</span> Here we're wrapping the
+call to the C&nbsp;function in a Lua function. This isn't strictly
+necessary, but it's helpful to deal with system-specific issues only
+in one part of the code. The way we're wrapping it ensures the check
+for the OS is only done during initialization and not for every call.
+</p>
+<p>
+<span class="mark">&#9315;</span> A more subtle point is
+that we defined our <tt>sleep()</tt> function (for the sake of this
+example) as taking the number of seconds, but accepting fractional
+seconds. Multiplying this by 1000 gets us milliseconds, but that still
+leaves it a Lua number, which is a floating-point value. Alas, the
+<tt>Sleep()</tt> function only accepts an integer value. Luckily for
+us, the FFI library automatically performs the conversion when calling
+the function (truncating the FP value towards zero, like in C).
+</p>
+<p style="font-size: 8pt;">
+Some readers will notice that <tt>Sleep()</tt> is part of
+<tt>KERNEL32.DLL</tt> and is also a <tt>stdcall</tt> function. So how
+can this possibly work? The FFI library provides the <tt>ffi.C</tt>
+default C&nbsp;library namespace, which allows calling functions from
+the default set of libraries, like a C&nbsp;compiler would. Also, the
+FFI library automatically detects <tt>stdcall</tt> functions, so you
+don't need to declare them as such.
+</p>
+<p>
+<span class="mark">&#9316;</span> The <tt>poll()</tt>
+function takes a couple more arguments we're not going to use. You can
+simply use <tt>nil</tt> to pass a <tt>NULL</tt> pointer and <tt>0</tt>
+for the <tt>nfds</tt> parameter. Please note that the
+number&nbsp;<tt>0</tt> <em>does not convert to a pointer value</em>,
+unlike in C++. You really have to pass pointers to pointer arguments
+and numbers to number arguments.
+</p>
+<p style="font-size: 8pt;">
+The page on <a href="ext_ffi_semantics.html">FFI semantics</a> has all
+of the gory details about
+<a href="ext_ffi_semantics.html#convert">conversions between Lua
+objects and C&nbsp;types</a>. For the most part you don't have to deal
+with this, as it's performed automatically and it's carefully designed
+to bridge the semantic differences between Lua and C.
+</p>
+<p>
+<span class="mark">&#9317;</span> Now that we have defined
+our own <tt>sleep()</tt> function, we can just call it from plain Lua
+code. That wasn't so bad, huh? Turning these boring animated dots into
+a fascinating best-selling game is left as an exercise for the reader.

+]]
+local zlib = ffi.load(ffi.os == "Windows" and "zlib1" or "z")
+
+local function compress(txt)
+  local n = zlib.compressBound(#txt)
+  local buf = ffi.new("uint8_t[?]", n)
+  local buflen = ffi.new("unsigned long[1]", n)

+print("Uncompressed size: ", #txt)
+local c = compress(txt)
+print("Compressed size: ", #c)
+local txt2 = uncompress(c, #txt)
+assert(txt2 == txt)
+</pre>
+<p>
+Here's the step-by-step explanation:
+</p>
+<p>
+<span class="mark">&#9312;</span> This defines some of the
+C&nbsp;functions provided by zlib. For the sake of this example, some
+type indirections have been reduced and it uses the pre-defined
+fixed-size integer types, while still adhering to the zlib API/ABI.
+</p>
+<p>
+<span class="mark">&#9313;</span> This loads the zlib shared
+library. On POSIX systems it's named <tt>libz.so</tt> and usually
+comes pre-installed. Since <tt>ffi.load()</tt> automatically adds any
+missing standard prefixes/suffixes, we can simply load the
+<tt>"z"</tt> library. On Windows it's named <tt>zlib1.dll</tt> and
+you'll have to download it first from the
+<a href="http://zlib.net/"><span class="ext">&raquo;</span>&nbsp;zlib site</a>. The check for
+<tt>ffi.os</tt> makes sure we pass the right name to
+<tt>ffi.load()</tt>.
+</p>
+<p>
+<span class="mark">&#9314;</span> First, the maximum size of
+the compression buffer is obtained by calling the
+<tt>zlib.compressBound</tt> function with the length of the
+uncompressed string. The next line allocates a byte buffer of this
+size. The <tt>[?]</tt> in the type specification indicates a
+variable-length array (VLA). The actual number of elements of this
+array is given as the 2nd argument to <tt>ffi.new()</tt>.
+</p>
+<p>
+<span class="mark">&#9315;</span> This may look strange at
+first, but have a look at the declaration of the <tt>compress2</tt>
+function from zlib: the destination length is defined as a pointer!
+This is because you pass in the maximum buffer size and get back the
+actual length that was used.
+</p>
+<p>
+In C you'd pass in the address of a local variable
+(<tt>&amp;buflen</tt>). But since there's no address-of operator in
+Lua, we'll just pass in a one-element array. Conveniently it can be
+initialized with the maximum buffer size in one step. Calling the
+actual <tt>zlib.compress2</tt> function is then straightforward.
+</p>
+<p>
+<span class="mark">&#9316;</span> We want to return the
+compressed data as a Lua string, so we'll use <tt>ffi.string()</tt>.
+It needs a pointer to the start of the data and the actual length. The
+length has been returned in the <tt>buflen</tt> array, so we'll just
+get it from there.
+</p>
+<p style="font-size: 8pt;">
+Note that since the function returns now, the <tt>buf</tt> and
+<tt>buflen</tt> variables will eventually be garbage collected. This
+is fine, because <tt>ffi.string()</tt> has copied the contents to a
+newly created (interned) Lua string. If you plan to call this function
+lots of times, consider reusing the buffers and/or handing back the
+results in buffers instead of strings. This will reduce the overhead
+for garbage collection and string interning.
+</p>
+<p>
+<span class="mark">&#9317;</span> The <tt>uncompress</tt>
+functions does the exact opposite of the <tt>compress</tt> function.
+The compressed data doesn't include the size of the original string,
+so this needs to be passed in. Otherwise no surprises here.
+</p>
+<p>
+<span class="mark">&#9318;</span> The code, that makes use
+of the functions we just defined, is just plain Lua code. It doesn't
+need to know anything about the LuaJIT FFI &mdash; the convenience
+wrapper functions completely hide it.
+</p>
+<p>
+One major advantage of the LuaJIT FFI is that you are now able to
+write those wrappers <em>in Lua</em>. And at a fraction of the time it
+would cost you to create an extra C&nbsp;module using the Lua/C API.
+Many of the simpler C&nbsp;functions can probably be used directly
+from your Lua code, without any wrappers.
+</p>
+<p style="font-size: 8pt;">
+Side note: the zlib API uses the <tt>long</tt> type for passing
+lengths and sizes around. But all those zlib functions actually only
+deal with 32&nbsp;bit values. This is an unfortunate choice for a
+public API, but may be explained by zlib's history &mdash; we'll just
+have to deal with it.
+</p>
+<p style="font-size: 8pt;">
+First, you should know that a <tt>long</tt> is a 64&nbsp;bit type e.g.
+on POSIX/x64 systems, but a 32&nbsp;bit type on Windows/x64 and on
+32&nbsp;bit systems. Thus a <tt>long</tt> result can be either a plain
+Lua number or a boxed 64&nbsp;bit integer cdata object, depending on
+the target system.
+</p>
+<p style="font-size: 8pt;">
+Ok, so the <tt>ffi.*</tt> functions generally accept cdata objects
+wherever you'd want to use a number. That's why we get a away with
+passing <tt>n</tt> to <tt>ffi.string()</tt> above. But other Lua
+library functions or modules don't know how to deal with this. So for
+maximum portability one needs to use <tt>tonumber()</tt> on returned
+<tt>long</tt> results before passing them on. Otherwise the
+application might work on some systems, but would fail in a POSIX/x64
+environment.
+</p>
+
+<h2 id="metatype">Defining Metamethods for a C&nbsp;Type</h2>
+<p>
+The following code explains how to define metamethods for a C type.
+We define a simple point type and add some operations to it:
+</p>
+<pre class="code mark">
+<span class="codemark">&nbsp;
+&#9312;
+
+
+
+&#9313;
+
+&#9314;
+
+&#9315;
+
+
+
+&#9316;
+
+&#9317;</span>local ffi = require("ffi")
+ffi.cdef[[
+<span style="color:#00a000;">typedef struct { double x, y; } point_t;</span>
+]]
+
+local point
+local mt = {
+  __add = function(a, b) return point(a.x+b.x, a.y+b.y) end,
+  __len = function(a) return math.sqrt(a.x*a.x + a.y*a.y) end,
+  __index = {
+    area = function(a) return a.x*a.x + a.y*a.y end,
+  },
+}
+point = ffi.metatype("point_t", mt)
+
+local a = point(3, 4)
+print(a.x, a.y)  --> 3  4
+print(#a)        --> 5
+print(a:area())  --> 25
+local b = a + point(0.5, 8)
+print(#b)        --> 12.5
+</pre>
+<p>
+Here's the step-by-step explanation:
+</p>
+<p>
+<span class="mark">&#9312;</span> This defines the C&nbsp;type for a
+two-dimensional point object.
+</p>
+<p>
+<span class="mark">&#9313;</span> We have to declare the variable
+holding the point constructor first, because it's used inside of a
+metamethod.
+</p>
+<p>
+<span class="mark">&#9314;</span> Let's define an <tt>__add</tt>
+metamethod which adds the coordinates of two points and creates a new
+point object. For simplicity, this function assumes that both arguments
+are points. But it could be any mix of objects, if at least one operand
+is of the required type (e.g. adding a point plus a number or vice
+versa). Our <tt>__len</tt> metamethod returns the distance of a point to
+the origin.
+</p>
+<p>
+<span class="mark">&#9315;</span> If we run out of operators, we can
+define named methods, too. Here the <tt>__index</tt> table defines an
+<tt>area</tt> function. For custom indexing needs, one might want to
+define <tt>__index</tt> and <tt>__newindex</tt> <em>functions</em> instead.
+</p>
+<p>
+<span class="mark">&#9316;</span> This associates the metamethods with
+our C&nbsp;type. This only needs to be done once. For convenience, a
+constructor is returned by
+<a href="ext_ffi_api.html#ffi_metatype"><tt>ffi.metatype()</tt></a>.
+We're not required to use it, though. The original C&nbsp;type can still
+be used e.g. to create an array of points. The metamethods automatically
+apply to any and all uses of this type.
+</p>
+<p>
+Please note that the association with a metatable is permanent and
+<b>the metatable must not be modified afterwards!</b> Ditto for the
+<tt>__index</tt> table.
+</p>
+<p>
+<span class="mark">&#9317;</span> Here are some simple usage examples
+for the point type and their expected results. The pre-defined
+operations (such as <tt>a.x</tt>) can be freely mixed with the newly
+defined metamethods. Note that <tt>area</tt> is a method and must be
+called with the Lua syntax for methods: <tt>a:area()</tt>, not
+<tt>a.area()</tt>.
+</p>
+<p>
+The C&nbsp;type metamethod mechanism is most useful when used in
+conjunction with C&nbsp;libraries that are written in an object-oriented
+style. Creators return a pointer to a new instance and methods take an
+instance pointer as the first argument. Sometimes you can just point
+<tt>__index</tt> to the library namespace and <tt>__gc</tt> to the
+destructor and you're done. But often enough you'll want to add
+convenience wrappers, e.g. to return actual Lua strings or when
+returning multiple values.
+</p>
+<p>
+Some C libraries only declare instance pointers as an opaque
+<tt>void&nbsp;*</tt> type. In this case you can use a fake type for all
+declarations, e.g. a pointer to a named (incomplete) struct will do:
+<tt>typedef struct foo_type *foo_handle</tt>. The C&nbsp;side doesn't
+know what you declare with the LuaJIT FFI, but as long as the underlying
+types are compatible, everything still works.

+</table>
+
+<h2 id="cache">To Cache or Not to Cache</h2>
+<p>
+It's a common Lua idiom to cache library functions in local variables
+or upvalues, e.g.:
+</p>
+<pre class="code">
+local byte, char = string.byte, string.char
+local function foo(x)
+  return char(byte(x)+1)
+end
+</pre>
+<p>
+This replaces several hash-table lookups with a (faster) direct use of
+a local or an upvalue. This is less important with LuaJIT, since the
+JIT compiler optimizes hash-table lookups a lot and is even able to
+hoist most of them out of the inner loops. It can't eliminate
+<em>all</em> of them, though, and it saves some typing for often-used
+functions. So there's still a place for this, even with LuaJIT.
+</p>
+<p>
+The situation is a bit different with C&nbsp;function calls via the
+FFI library. The JIT compiler has special logic to eliminate <em>all
+of the lookup overhead</em> for functions resolved from a
+<a href="ext_ffi_semantics.html#clib">C&nbsp;library namespace</a>!
+Thus it's not helpful and actually counter-productive to cache
+individual C&nbsp;functions like this:
+</p>
+<pre class="code">
+local <b>funca</b>, <b>funcb</b> = ffi.C.funca, ffi.C.funcb -- <span style="color:#c00000;">Not helpful!</span>
+local function foo(x, n)
+  for i=1,n do <b>funcb</b>(<b>funca</b>(x, i), 1) end
+end
+</pre>
+<p>
+This turns them into indirect calls and generates bigger and slower
+machine code. Instead you'll want to cache the namespace itself and
+rely on the JIT compiler to eliminate the lookups:
+</p>
+<pre class="code">
+local <b>C</b> = ffi.C          -- <span style="color:#00a000;">Instead use this!</span>
+local function foo(x, n)
+  for i=1,n do <b>C.funcb</b>(<b>C.funca</b>(x, i), 1) end
+end
+</pre>
+<p>
+This generates both shorter and faster code. So <b>don't cache
+C&nbsp;functions</b>, but <b>do</b> cache namespaces! Most often the
+namespace is already in a local variable at an outer scope, e.g. from
+<tt>local&nbsp;lib&nbsp;=&nbsp;ffi.load(...)</tt>. Note that copying
+it to a local variable in the function scope is unnecessary.

+jit.flush(func|true [,true|false])</tt></h3>
+<p>
+<tt>jit.on</tt> enables JIT compilation for a Lua function (this is
+the default).
+</p>
+<p>
+<tt>jit.off</tt> disables JIT compilation for a Lua function and
+flushes any already compiled code from the code cache.
+</p>
+<p>
+<tt>jit.flush</tt> flushes the code, but doesn't affect the
+enable/disable status.
+</p>
+<p>
+The current function, i.e. the Lua function calling this library
+function, can also be specified by passing <tt>true</tt> as the first
+argument.
+</p>
+<p>
+If the second argument is <tt>true</tt>, JIT compilation is also
+enabled, disabled or flushed recursively for all sub-functions of a
+function. With <tt>false</tt> only the sub-functions are affected.
+</p>
+<p>
+The <tt>jit.on</tt> and <tt>jit.off</tt> functions only set a flag
+which is checked when the function is about to be compiled. They do
+not trigger immediate compilation.
+</p>
+<p>
+Typical usage is <tt>jit.off(true, true)</tt> in the main chunk
+of a module to turn off JIT compilation for the whole module for
+debugging purposes.
+</p>
+
+<h3 id="jit_flush_tr"><tt>jit.flush(tr)</tt></h3>
+<p>
+Flushes the root trace, specified by its number, and all of its side
+traces from the cache. The code for the trace will be retained as long
+as there are any other traces which link to it.
+</p>
+
+<h3 id="jit_status"><tt>status, ... = jit.status()</tt></h3>
+<p>
+Returns the current status of the JIT compiler. The first result is
+either <tt>true</tt> or <tt>false</tt> if the JIT compiler is turned
+on or off. The remaining results are strings for CPU-specific features
+and enabled optimizations.
+</p>
+
+<h3 id="jit_version"><tt>jit.version</tt></h3>
+<p>
+Contains the LuaJIT version string.
+</p>
+
+<h3 id="jit_version_num"><tt>jit.version_num</tt></h3>
+<p>
+Contains the version number of the LuaJIT core. Version xx.yy.zz
+is represented by the decimal number xxyyzz.
+</p>
+
+<h3 id="jit_os"><tt>jit.os</tt></h3>
+<p>
+Contains the target OS name:
+"Windows", "Linux", "OSX", "BSD", "POSIX" or "Other".
+</p>
+
+<h3 id="jit_arch"><tt>jit.arch</tt></h3>
+<p>
+Contains the target architecture name:
+"x86", "x64", "arm", "arm64", "ppc", "mips" or "mips64".
+</p>
+
+<h2 id="jit_opt"><tt>jit.opt.*</tt> &mdash; JIT compiler optimization control</h2>
+<p>
+This sub-module provides the backend for the <tt>-O</tt> command line
+option.
+</p>
+<p>
+You can also use it programmatically, e.g.:
+</p>
+<pre class="code">
+jit.opt.start(2) -- same as -O2
+jit.opt.start("-dce")
+jit.opt.start("hotloop=10", "hotexit=2")
+</pre>
+<p>
+Unlike in LuaJIT 1.x, the module is built-in and
+<b>optimization is turned on by default!</b>
+It's no longer necessary to run <tt>require("jit.opt").start()</tt>,
+which was one of the ways to enable optimization.
+</p>
+
+<h2 id="jit_util"><tt>jit.util.*</tt> &mdash; JIT compiler introspection</h2>
+<p>
+This sub-module holds functions to introspect the bytecode, generated
+traces, the IR and the generated machine code. The functionality
+provided by this module is still in flux and therefore undocumented.
+</p>
+<p>
+The debug modules <tt>-jbc</tt>, <tt>-jv</tt> and <tt>-jdump</tt> make
+extensive use of these functions. Please check out their source code,
+if you want to know more.

+<p>
+LuaJIT has an integrated statistical profiler with very low overhead. It
+allows sampling the currently executing stack and other parameters in
+regular intervals.
+</p>
+<p>
+The integrated profiler can be accessed from three levels:
+</p>
+<ul>
+<li>The <a href="#hl_profiler">bundled high-level profiler</a>, invoked by the
+<a href="#j_p"><tt>-jp</tt></a> command line option.</li>
+<li>A <a href="#ll_lua_api">low-level Lua API</a> to control the profiler.</li>
+<li>A <a href="#ll_c_api">low-level C API</a> to control the profiler.</li>
+</ul>
+
+<h2 id="hl_profiler">High-Level Profiler</h2>
+<p>
+The bundled high-level profiler offers basic profiling functionality. It
+generates simple textual summaries or source code annotations. It can be
+accessed with the <a href="#j_p"><tt>-jp</tt></a> command line option
+or from Lua code by loading the underlying <tt>jit.p</tt> module.
+</p>
+<p>
+To cut to the chase &mdash; run this to get a CPU usage profile by
+function name:
+</p>
+<pre class="code">
+luajit -jp myapp.lua
+</pre>
+<p>
+It's <em>not</em> a stated goal of the bundled profiler to add every
+possible option or to cater for special profiling needs. The low-level
+profiler APIs are documented below. They may be used by third-party
+authors to implement advanced functionality, e.g. IDE integration or
+graphical profilers.
+</p>
+<p>
+Note: Sampling works for both interpreted and JIT-compiled code. The
+results for JIT-compiled code may sometimes be surprising. LuaJIT
+heavily optimizes and inlines Lua code &mdash; there's no simple
+one-to-one correspondence between source code lines and the sampled
+machine code.
+</p>
+
+<h3 id="j_p"><tt>-jp=[options[,output]]</tt></h3>
+<p>
+The <tt>-jp</tt> command line option starts the high-level profiler.
+When the application run by the command line terminates, the profiler
+stops and writes the results to <tt>stdout</tt> or to the specified
+<tt>output</tt> file.
+</p>
+<p>
+The <tt>options</tt> argument specifies how the profiling is to be
+performed:
+</p>
+<ul>
+<li><tt>f</tt> &mdash; Stack dump: function name, otherwise module:line.
+This is the default mode.</li>
+<li><tt>F</tt> &mdash; Stack dump: ditto, but dump module:name.</li>
+<li><tt>l</tt> &mdash; Stack dump: module:line.</li>
+<li><tt>&lt;number&gt;</tt> &mdash; stack dump depth (callee &larr;
+caller). Default: 1.</li>
+<li><tt>-&lt;number&gt;</tt> &mdash; Inverse stack dump depth (caller
+&rarr; callee).</li>
+<li><tt>s</tt> &mdash; Split stack dump after first stack level. Implies
+depth&nbsp;&ge;&nbsp;2 or depth&nbsp;&le;&nbsp;-2.</li>
+<li><tt>p</tt> &mdash; Show full path for module names.</li>
+<li><tt>v</tt> &mdash; Show VM states.</li>
+<li><tt>z</tt> &mdash; Show <a href="#jit_zone">zones</a>.</li>
+<li><tt>r</tt> &mdash; Show raw sample counts. Default: show percentages.</li>
+<li><tt>a</tt> &mdash; Annotate excerpts from source code files.</li>
+<li><tt>A</tt> &mdash; Annotate complete source code files.</li>
+<li><tt>G</tt> &mdash; Produce raw output suitable for graphical tools.</li>
+<li><tt>m&lt;number&gt;</tt> &mdash; Minimum sample percentage to be shown.
+Default: 3%.</li>
+<li><tt>i&lt;number&gt;</tt> &mdash; Sampling interval in milliseconds.
+Default: 10ms.<br>
+Note: The actual sampling precision is OS-dependent.</li>
+</ul>
+<p>
+The default output for <tt>-jp</tt> is a list of the most CPU consuming
+spots in the application. Increasing the stack dump depth with (say)
+<tt>-jp=2</tt> may help to point out the main callers or callees of
+hotspots. But sample aggregation is still flat per unique stack dump.
+</p>
+<p>
+To get a two-level view (split view) of callers/callees, use
+<tt>-jp=s</tt> or <tt>-jp=-s</tt>. The percentages shown for the second
+level are relative to the first level.
+</p>
+<p>
+To see how much time is spent in each line relative to a function, use
+<tt>-jp=fl</tt>.
+</p>
+<p>
+To see how much time is spent in different VM states or
+<a href="#jit_zone">zones</a>, use <tt>-jp=v</tt> or <tt>-jp=z</tt>.
+</p>
+<p>
+Combinations of <tt>v/z</tt> with <tt>f/F/l</tt> produce two-level
+views, e.g. <tt>-jp=vf</tt> or <tt>-jp=fv</tt>. This shows the time
+spent in a VM state or zone vs. hotspots. This can be used to answer
+questions like "Which time consuming functions are only interpreted?" or
+"What's the garbage collector overhead for a specific function?".
+</p>
+<p>
+Multiple options can be combined &mdash; but not all combinations make
+sense, see above. E.g. <tt>-jp=3si4m1</tt> samples three stack levels
+deep in 4ms intervals and shows a split view of the CPU consuming
+functions and their callers with a 1% threshold.
+</p>
+<p>
+Source code annotations produced by <tt>-jp=a</tt> or <tt>-jp=A</tt> are
+always flat and at the line level. Obviously, the source code files need
+to be readable by the profiler script.
+</p>
+<p>
+The high-level profiler can also be started and stopped from Lua code with:
+</p>
+<pre class="code">
+require("jit.p").start(options, output)
+...
+require("jit.p").stop()
+</pre>
+
+<h3 id="jit_zone"><tt>jit.zone</tt> &mdash; Zones</h3>
+<p>
+Zones can be used to provide information about different parts of an
+application to the high-level profiler. E.g. a game could make use of an
+<tt>"AI"</tt> zone, a <tt>"PHYS"</tt> zone, etc. Zones are hierarchical,
+organized as a stack.
+</p>
+<p>
+The <tt>jit.zone</tt> module needs to be loaded explicitly:
+</p>
+<pre class="code">
+local zone = require("jit.zone")
+</pre>
+<ul>
+<li><tt>zone("name")</tt> pushes a named zone to the zone stack.</li>
+<li><tt>zone()</tt> pops the current zone from the zone stack and
+returns its name.</li>
+<li><tt>zone:get()</tt> returns the current zone name or <tt>nil</tt>.</li>
+<li><tt>zone:flush()</tt> flushes the zone stack.</li>
+</ul>
+<p>
+To show the time spent in each zone use <tt>-jp=z</tt>. To show the time
+spent relative to hotspots use e.g. <tt>-jp=zf</tt> or <tt>-jp=fz</tt>.
+</p>
+
+<h2 id="ll_lua_api">Low-level Lua API</h2>
+<p>
+The <tt>jit.profile</tt> module gives access to the low-level API of the
+profiler from Lua code. This module needs to be loaded explicitly:
+<pre class="code">
+local profile = require("jit.profile")
+</pre>
+<p>
+This module can be used to implement your own higher-level profiler.
+A typical profiling run starts the profiler, captures stack dumps in
+the profiler callback, adds them to a hash table to aggregate the number
+of samples, stops the profiler and then analyzes all of the captured
+stack dumps. Other parameters can be sampled in the profiler callback,
+too. But it's important not to spend too much time in the callback,
+since this may skew the statistics.
+</p>
+
+<h3 id="profile_start"><tt>profile.start(mode, cb)</tt>
+&mdash; Start profiler</h3>
+<p>
+This function starts the profiler. The <tt>mode</tt> argument is a
+string holding options:
+</p>
+<ul>
+<li><tt>f</tt> &mdash; Profile with precision down to the function level.</li>
+<li><tt>l</tt> &mdash; Profile with precision down to the line level.</li>
+<li><tt>i&lt;number&gt;</tt> &mdash; Sampling interval in milliseconds (default
+10ms).</br>
+Note: The actual sampling precision is OS-dependent.
+</li>
+</ul>
+<p>
+The <tt>cb</tt> argument is a callback function which is called with
+three arguments: <tt>(thread, samples, vmstate)</tt>. The callback is
+called on a separate coroutine, the <tt>thread</tt> argument is the
+state that holds the stack to sample for profiling. Note: do
+<em>not</em> modify the stack of that state or call functions on it.
+</p>
+<p>
+<tt>samples</tt> gives the number of accumulated samples since the last
+callback (usually 1).
+</p>
+<p>
+<tt>vmstate</tt> holds the VM state at the time the profiling timer
+triggered. This may or may not correspond to the state of the VM when
+the profiling callback is called. The state is either <tt>'N'</tt>
+native (compiled) code, <tt>'I'</tt> interpreted code, <tt>'C'</tt>
+C&nbsp;code, <tt>'G'</tt> the garbage collector, or <tt>'J'</tt> the JIT
+compiler.
+</p>
+
+<h3 id="profile_stop"><tt>profile.stop()</tt>
+&mdash; Stop profiler</h3>
+<p>
+This function stops the profiler.
+</p>
+
+<h3 id="profile_dump"><tt>dump = profile.dumpstack([thread,] fmt, depth)</tt>
+&mdash; Dump stack </h3>
+<p>
+This function allows taking stack dumps in an efficient manner. It
+returns a string with a stack dump for the <tt>thread</tt> (coroutine),
+formatted according to the <tt>fmt</tt> argument:
+</p>
+<ul>
+<li><tt>p</tt> &mdash; Preserve the full path for module names. Otherwise
+only the file name is used.</li>
+<li><tt>f</tt> &mdash; Dump the function name if it can be derived. Otherwise
+use module:line.</li>
+<li><tt>F</tt> &mdash; Ditto, but dump module:name.</li>
+<li><tt>l</tt> &mdash; Dump module:line.</li>
+<li><tt>Z</tt> &mdash; Zap the following characters for the last dumped
+frame.</li>
+<li>All other characters are added verbatim to the output string.</li>
+</ul>
+<p>
+The <tt>depth</tt> argument gives the number of frames to dump, starting
+at the topmost frame of the thread. A negative number dumps the frames in
+inverse order.
+</p>
+<p>
+The first example prints a list of the current module names and line
+numbers of up to 10 frames in separate lines. The second example prints
+semicolon-separated function names for all frames (up to 100) in inverse
+order:
+</p>
+<pre class="code">
+print(profile.dumpstack(thread, "l\n", 10))
+print(profile.dumpstack(thread, "lZ;", -100))
+</pre>
+
+<h2 id="ll_c_api">Low-level C API</h2>
+<p>
+The profiler can be controlled directly from C&nbsp;code, e.g. for
+use by IDEs. The declarations are in <tt>"luajit.h"</tt> (see
+<a href="ext_c_api.html">Lua/C API</a> extensions).
+</p>
+
+<h3 id="luaJIT_profile_start"><tt>luaJIT_profile_start(L, mode, cb, data)</tt>
+&mdash; Start profiler</h3>
+<p>
+This function starts the profiler. <a href="#profile_start">See
+above</a> for a description of the <tt>mode</tt> argument.
+</p>
+<p>
+The <tt>cb</tt> argument is a callback function with the following
+declaration:
+</p>
+<pre class="code">
+typedef void (*luaJIT_profile_callback)(void *data, lua_State *L,
+                                        int samples, int vmstate);
+</pre>
+<p>
+<tt>data</tt> is available for use by the callback. <tt>L</tt> is the
+state that holds the stack to sample for profiling. Note: do
+<em>not</em> modify this stack or call functions on this stack &mdash;
+use a separate coroutine for this purpose. <a href="#profile_start">See
+above</a> for a description of <tt>samples</tt> and <tt>vmstate</tt>.
+</p>
+
+<h3 id="luaJIT_profile_stop"><tt>luaJIT_profile_stop(L)</tt>
+&mdash; Stop profiler</h3>
+<p>
+This function stops the profiler.
+</p>
+
+<h3 id="luaJIT_profile_dumpstack"><tt>p = luaJIT_profile_dumpstack(L, fmt, depth, len)</tt>
+&mdash; Dump stack </h3>
+<p>
+This function allows taking stack dumps in an efficient manner.
+<a href="#profile_dump">See above</a> for a description of <tt>fmt</tt>
+and <tt>depth</tt>.
+</p>
+<p>
+This function returns a <tt>const&nbsp;char&nbsp;*</tt> pointing to a
+private string buffer of the profiler. The <tt>int&nbsp;*len</tt>
+argument returns the length of the output string. The buffer is
+overwritten on the next call and deallocated when the profiler stops.
+You either need to consume the content immediately or copy it for later
+use.

+</p>
+<p>
+LuaJIT is also fully ABI-compatible to Lua 5.1 at the linker/dynamic

+</p>
+<p>
+LuaJIT extends the standard Lua VM with new functionality and adds

+This module is a LuaJIT built-in &mdash; you don't need to download or
+install Lua BitOp. The Lua BitOp site has full documentation for all
+<a href="http://bitop.luajit.org/api.html"><span class="ext">&raquo;</span>&nbsp;Lua BitOp API functions</a>.
+The FFI adds support for
+<a href="ext_ffi_semantics.html#cdata_arith">64&nbsp;bit bitwise operations</a>,
+using the same API functions.
+</p>
+<p>
+Please make sure to <tt>require</tt> the module before using any of
+its functions:
+</p>
+<pre class="code">
+local bit = require("bit")
+</pre>
+<p>
+An already installed Lua BitOp module is ignored by LuaJIT.
+This way you can use bit operations from both Lua and LuaJIT on a
+shared installation.
+</p>
+
+<h3 id="ffi"><tt>ffi.*</tt> &mdash; FFI library</h3>
+<p>
+The <a href="ext_ffi.html">FFI library</a> allows calling external
+C&nbsp;functions and the use of C&nbsp;data structures from pure Lua
+code.
+</p>
+
+<h3 id="jit"><tt>jit.*</tt> &mdash; JIT compiler control</h3>
+<p>
+The functions in this module
+<a href="ext_jit.html">control the behavior of the JIT compiler engine</a>.
+</p>
+
+<h3 id="c_api">C API extensions</h3>
+<p>
+LuaJIT adds some
+<a href="ext_c_api.html">extra functions to the Lua/C API</a>.
+</p>
+
+<h3 id="profiler">Profiler</h3>
+<p>
+LuaJIT has an <a href="ext_profiler.html">integrated profiler</a>.
+</p>
+
+<h2 id="library">Enhanced Standard Library Functions</h2>
+
+<h3 id="xpcall"><tt>xpcall(f, err [,args...])</tt> passes arguments</h3>
+<p>
+Unlike the standard implementation in Lua 5.1, <tt>xpcall()</tt>
+passes any arguments after the error function to the function
+which is called in a protected context.
+</p>
+
+<h3 id="load"><tt>loadfile()</tt> etc. handle UTF-8 source code</h3>
+<p>
+Non-ASCII characters are handled transparently by the Lua source code parser.
+This allows the use of UTF-8 characters in identifiers and strings.
+A UTF-8 BOM is skipped at the start of the source code.
+</p>
+
+<h3 id="tostring"><tt>tostring()</tt> etc. canonicalize NaN and &plusmn;Inf</h3>
+<p>
+All number-to-string conversions consistently convert non-finite numbers
+to the same strings on all platforms. NaN results in <tt>"nan"</tt>,
+positive infinity results in <tt>"inf"</tt> and negative infinity results
+in <tt>"-inf"</tt>.
+</p>
+
+<h3 id="tonumber"><tt>tonumber()</tt> etc. use builtin string to number conversion</h3>
+<p>
+All string-to-number conversions consistently convert integer and
+floating-point inputs in decimal, hexadecimal and binary on all platforms.
+<tt>strtod()</tt> is <em>not</em> used anymore, which avoids numerous
+problems with poor C library implementations. The builtin conversion
+function provides full precision according to the IEEE-754 standard, it
+works independently of the current locale and it supports hex floating-point
+numbers (e.g. <tt>0x1.5p-3</tt>).
+</p>
+
+<h3 id="string_dump"><tt>string.dump(f [,strip])</tt> generates portable bytecode</h3>
+<p>
+An extra argument has been added to <tt>string.dump()</tt>. If set to
+<tt>true</tt>, 'stripped' bytecode without debug information is
+generated. This speeds up later bytecode loading and reduces memory
+usage. See also the
+<a href="running.html#opt_b"><tt>-b</tt> command line option</a>.
+</p>
+<p>
+The generated bytecode is portable and can be loaded on any architecture
+that LuaJIT supports, independent of word size or endianess. However the
+bytecode compatibility versions must match. Bytecode stays compatible
+for dot releases (x.y.0 &rarr; x.y.1), but may change with major or
+minor releases (2.0 &rarr; 2.1) or between any beta release. Foreign
+bytecode (e.g. from Lua 5.1) is incompatible and cannot be loaded.
+</p>
+<p>
+Note: <tt>LJ_GC64</tt> mode requires a different frame layout, which implies
+a different, incompatible bytecode format for ports that use this mode (e.g.
+ARM64 or MIPS64) or when explicitly enabled for x64. This may be rectified
+in the future.
+</p>
+
+<h3 id="table_new"><tt>table.new(narray, nhash)</tt> allocates a pre-sized table</h3>
+<p>
+An extra library function <tt>table.new()</tt> can be made available via
+<tt>require("table.new")</tt>. This creates a pre-sized table, just like
+the C API equivalent <tt>lua_createtable()</tt>. This is useful for big
+tables if the final table size is known and automatic table resizing is
+too expensive.
+</p>
+
+<h3 id="table_clear"><tt>table.clear(tab)</tt> clears a table</h3>
+<p>
+An extra library function <tt>table.clear()</tt> can be made available
+via <tt>require("table.clear")</tt>. This clears all keys and values
+from a table, but preserves the allocated array/hash sizes. This is
+useful when a table, which is linked from multiple places, needs to be
+cleared and/or when recycling a table for use by the same context. This
+avoids managing backlinks, saves an allocation and the overhead of
+incremental array/hash part growth.
+</p>
+<p>
+Please note this function is meant for very specific situations. In most
+cases it's better to replace the (usually single) link with a new table
+and let the GC do its work.
+</p>
+
+<h3 id="math_random">Enhanced PRNG for <tt>math.random()</tt></h3>
+<p>
+LuaJIT uses a Tausworthe PRNG with period 2^223 to implement
+<tt>math.random()</tt> and <tt>math.randomseed()</tt>. The quality of
+the PRNG results is much superior compared to the standard Lua
+implementation which uses the platform-specific ANSI rand().
+</p>
+<p>
+The PRNG generates the same sequences from the same seeds on all
+platforms and makes use of all bits in the seed argument.
+<tt>math.random()</tt> without arguments generates 52 pseudo-random bits
+for every call. The result is uniformly distributed between 0.0 and 1.0.
+It's correctly scaled up and rounded for <tt>math.random(n&nbsp;[,m])</tt> to
+preserve uniformity.
+</p>
+
+<h3 id="io"><tt>io.*</tt> functions handle 64&nbsp;bit file offsets</h3>
+<p>
+The file I/O functions in the standard <tt>io.*</tt> library handle
+64&nbsp;bit file offsets. In particular this means it's possible
+to open files larger than 2&nbsp;Gigabytes and to reposition or obtain
+the current file position for offsets beyond 2&nbsp;GB
+(<tt>fp:seek()</tt> method).
+</p>
+
+<h3 id="debug_meta"><tt>debug.*</tt> functions identify metamethods</h3>
+<p>
+<tt>debug.getinfo()</tt> and <tt>lua_getinfo()</tt> also return information
+about invoked metamethods. The <tt>namewhat</tt> field is set to
+<tt>"metamethod"</tt> and the <tt>name</tt> field has the name of
+the corresponding metamethod (e.g. <tt>"__index"</tt>).
+</p>
+
+<h2 id="resumable">Fully Resumable VM</h2>
+<p>
+The LuaJIT VM is fully resumable. This means you can yield from a
+coroutine even across contexts, where this would not possible with
+the standard Lua&nbsp;5.1 VM: e.g. you can yield across <tt>pcall()</tt>
+and <tt>xpcall()</tt>, across iterators and across metamethods.
+</p>
+
+<h2 id="lua52">Extensions from Lua 5.2</h2>
+<p>
+LuaJIT supports some language and library extensions from Lua&nbsp;5.2.
+Features that are unlikely to break existing code are unconditionally
+enabled:
+</p>
+<ul>
+<li><tt>goto</tt> and <tt>::labels::</tt>.</li>
+<li>Hex escapes <tt>'\x3F'</tt> and <tt>'\*'</tt> escape in strings.</li>

+<li><tt>debug.getlocal()</tt> accepts function instead of level.</li>
+<li><tt>debug.getlocal()</tt> and <tt>debug.setlocal()</tt> accept negative
+indexes for varargs.</li>
+<li><tt>debug.getupvalue()</tt> and <tt>debug.setupvalue()</tt> handle
+C&nbsp;functions.</li>
+<li><tt>debug.upvalueid()</tt> and <tt>debug.upvaluejoin()</tt>.</li>
+<li>Lua/C API extensions:

+</li>
+<li>Command line option <tt>-E</tt>.</li>
+<li>Command line checks <tt>__tostring</tt> for errors.</li>
+</ul>
+<p>
+Other features are only enabled, if LuaJIT is built with
+<tt>-DLUAJIT_ENABLE_LUA52COMPAT</tt>:
+</p>
+<ul>
+<li><tt>goto</tt> is a keyword and not a valid variable name anymore.</li>
+<li><tt>break</tt> can be placed anywhere. Empty statements (<tt>;;</tt>)

+<li><tt>coroutine.running()</tt> returns two results.</li>

+<li><tt>package.searchers</tt>.</li>
+<li><tt>module()</tt> returns the module table.</li>
+</ul>
+<p>
+Note: this provides only partial compatibility with Lua 5.2 at the
+language and Lua library level. LuaJIT is API+ABI-compatible with
+Lua&nbsp;5.1, which prevents implementing features that would otherwise
+break the Lua/C API and ABI (e.g. <tt>_ENV</tt>).
+</p>
+
+<h2 id="lua53">Extensions from Lua 5.3</h2>
+<p>
+LuaJIT supports some extensions from Lua&nbsp;5.3:
+<ul>
+<li>Unicode escape <tt>'\u{XX...}'</tt> embeds the UTF-8 encoding in string literals.</li>
+<li>The argument table <tt>arg</tt> can be read (and modified) by <tt>LUA_INIT</tt> and <tt>-e</tt> chunks.</li>
+<li><tt>io.read()</tt> and <tt>file:read()</tt> accept formats with or without a leading <tt>*</tt>.</li>
+<li><tt>assert()</tt> accepts any type of error object.</li>
+<li><tt>table.move(a1, f, e, t [,a2])</tt>.</li>
+<li><tt>coroutine.isyieldable()</tt>.</li>
+<li>Lua/C API extensions:
+<tt>lua_isyieldable()</tt>
+</li>
+</ul>
+
+<h2 id="exceptions">C++ Exception Interoperability</h2>
+<p>
+LuaJIT has built-in support for interoperating with C++&nbsp;exceptions.
+The available range of features depends on the target platform and
+the toolchain used to compile LuaJIT:

+<dt>Q: Why do I get this error: "attempt to index global 'arg' (a nil value)"?<br>
+Q: My vararg functions fail after switching to LuaJIT!</dt>
+<dd>LuaJIT is compatible to the Lua 5.1 language standard. It doesn't
+support the implicit <tt>arg</tt> parameter for old-style vararg
+functions from Lua 5.0.<br>Please convert your code to the
+<a href="http://www.lua.org/manual/5.1/manual.html#2.5.9"><span class="ext">&raquo;</span>&nbsp;Lua 5.1
+vararg syntax</a>.</dd>
+</dl>
+
+<dl>
+<dt>Q: Why do I get this error: "bad FPU precision"?<br>
+<dt>Q: I get weird behavior after initializing Direct3D.<br>
+<dt>Q: Some FPU operations crash after I load a Delphi DLL.<br>
+</dt>
+<dd>
+
+DirectX/Direct3D (up to version 9) sets the x87 FPU to single-precision
+mode by default. This violates the Windows ABI and interferes with the
+operation of many programs &mdash; LuaJIT is affected, too. Please make
+sure you always use the <tt>D3DCREATE_FPU_PRESERVE</tt> flag when
+initializing Direct3D.<br>
+
+Direct3D version 10 or higher do not show this behavior anymore.
+Consider testing your application with older versions, too.<br>
+
+Similarly, the Borland/Delphi runtime modifies the FPU control word and
+enables FP exceptions. Of course this violates the Windows ABI, too.
+Please check the Delphi docs for the Set8087CW method.
+
+</dl>
+
+<dl>
+<dt>Q: Sometimes Ctrl-C fails to stop my Lua program. Why?</dt>
+<dd>The interrupt signal handler sets a Lua debug hook. But this is
+currently ignored by compiled code (this will eventually be fixed). If
+your program is running in a tight loop and never falls back to the
+interpreter, the debug hook never runs and can't throw the
+"interrupted!" error.<br> In the meantime you have to press Ctrl-C
+twice to get stop your program. That's similar to when it's stuck
+running inside a C function under the Lua interpreter.</dd>
+</dl>
+
+<dl>
+<dt>Q: Why doesn't my favorite power-patch for Lua apply against LuaJIT?</dt>
+<dd>Because it's a completely redesigned VM and has very little code
+in common with Lua anymore. Also, if the patch introduces changes to
+the Lua semantics, these would need to be reflected everywhere in the
+VM, from the interpreter up to all stages of the compiler.<br> Please
+use only standard Lua language constructs. For many common needs you
+can use source transformations or use wrapper or proxy functions.
+The compiler will happily optimize away such indirections.</dd>
+</dl>
+
+<dl>
+<dt>Q: Lua runs everywhere. Why doesn't LuaJIT support my CPU?</dt>
+<dd>Because it's a compiler &mdash; it needs to generate native
+machine code. This means the code generator must be ported to each
+architecture. And the fast interpreter is written in assembler and
+must be ported, too. This is quite an undertaking.<br>
+The <a href="install.html">install documentation</a> shows the supported
+architectures. Other architectures will follow based on sufficient user
+demand and/or sponsoring.</dd>

+<dl>
+<dt>Q: When will feature X be added? When will the next version be released?</dt>
+<dd>When it's ready.<br>
+C'mon, it's open source &mdash; I'm doing it on my own time and you're
+getting it for free. You can either contribute a patch or sponsor
+the development of certain features, if they are important to you.

+<h2>Configuring LuaJIT</h2>
+<p>
+The standard configuration should work fine for most installations.
+Usually there is no need to tweak the settings. The following files
+hold all user-configurable settings:
+</p>
+<ul>
+<li><tt>src/luaconf.h</tt> sets some configuration variables.</li>
+<li><tt>Makefile</tt> has settings for <b>installing</b> LuaJIT (POSIX
+only).</li>
+<li><tt>src/Makefile</tt> has settings for <b>compiling</b> LuaJIT
+under POSIX, MinGW or Cygwin.</li>
+<li><tt>src/msvcbuild.bat</tt> has settings for compiling LuaJIT with
+MSVC or WinSDK.</li>
+</ul>
+<p>
+Please read the instructions given in these files, before changing
+any settings.
+</p>
+<p>
+LuaJIT on x64 currently uses 32 bit GC objects by default.
+<tt>LJ_GC64</tt> mode may be explicitly enabled:
+add <tt>XCFLAGS=-DLUAJIT_ENABLE_GC64</tt> to the make command or run
+<tt>msvcbuild gc64</tt> for MSVC/WinSDK. Please check the note
+about the <a href="extensions.html#string_dump">bytecode format</a>
+differences, too.
+</p>
+
+<h2 id="posix">POSIX Systems (Linux, OSX, *BSD etc.)</h2>
+<h3>Prerequisites</h3>
+<p>
+Depending on your distribution, you may need to install a package for
+GCC, the development headers and/or a complete SDK. E.g. on a current
+Debian/Ubuntu, install <tt>libc6-dev</tt> with the package manager.
+</p>
+<p>
+Download the current source package of LuaJIT (pick the .tar.gz),
+if you haven't already done so. Move it to a directory of your choice,
+open a terminal window and change to this directory. Now unpack the archive
+and change to the newly created directory:
+</p>
+<pre class="code">
+tar zxf LuaJIT-2.0.5.tar.gz
+cd LuaJIT-2.0.5</pre>
+<h3>Building LuaJIT</h3>
+<p>
+The supplied Makefiles try to auto-detect the settings needed for your
+operating system and your compiler. They need to be run with GNU Make,
+which is probably the default on your system, anyway. Simply run:
+</p>
+<pre class="code">
+make
+</pre>
+<p>
+This always builds a native binary, depending on the host OS
+you're running this command on. Check the section on
+<a href="#cross">cross-compilation</a> for more options.
+</p>
+<p>
+By default, modules are only searched under the prefix <tt>/usr/local</tt>.
+You can add an extra prefix to the search paths by appending the
+<tt>PREFIX</tt> option, e.g.:
+</p>
+<pre class="code">
+make PREFIX=/home/myself/lj2
+</pre>
+<p>
+Note for OSX: if the <tt>MACOSX_DEPLOYMENT_TARGET</tt> environment
+variable is not set, then it's forced to <tt>10.4</tt>.
+</p>
+<h3>Installing LuaJIT</h3>
+<p>
+The top-level Makefile installs LuaJIT by default under
+<tt>/usr/local</tt>, i.e. the executable ends up in
+<tt>/usr/local/bin</tt> and so on. You need root privileges
+to write to this path. So, assuming sudo is installed on your system,
+run the following command and enter your sudo password:
+</p>
+<pre class="code">
+sudo make install
+</pre>
+<p>
+Otherwise specify the directory prefix as an absolute path, e.g.:
+</p>
+<pre class="code">
+make install PREFIX=/home/myself/lj2
+</pre>
+<p>
+Obviously the prefixes given during build and installation need to be the same.
+</p>
+
+<h2 id="windows">Windows Systems</h2>
+<h3>Prerequisites</h3>
+<p>
+Either install one of the open source SDKs
+(<a href="http://mingw.org/"><span class="ext">&raquo;</span>&nbsp;MinGW</a> or
+<a href="http://www.cygwin.com/"><span class="ext">&raquo;</span>&nbsp;Cygwin</a>), which come with a modified
+GCC plus the required development headers.
+</p>
+<p>
+Or install Microsoft's Visual C++ (MSVC). The freely downloadable
+<a href="http://www.microsoft.com/Express/VC/"><span class="ext">&raquo;</span>&nbsp;Express Edition</a>
+works just fine, but only contains an x86 compiler.
+</p>
+<p>
+The freely downloadable
+<a href="http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx"><span class="ext">&raquo;</span>&nbsp;Windows SDK</a>
+only comes with command line tools, but this is all you need to build LuaJIT.
+It contains x86 and x64 compilers.
+</p>
+<p>
+Next, download the source package and unpack it using an archive manager
+(e.g. the Windows Explorer) to a directory of your choice.
+</p>
+<h3>Building with MSVC</h3>
+<p>
+Open a "Visual Studio .NET Command Prompt", <tt>cd</tt> to the
+directory where you've unpacked the sources and run these commands:
+</p>
+<pre class="code">
+cd src
+msvcbuild
+</pre>
+<p>
+Then follow the installation instructions below.
+</p>
+<h3>Building with the Windows SDK</h3>
+<p>
+Open a "Windows SDK Command Shell" and select the x86 compiler:
+</p>
+<pre class="code">
+setenv /release /x86
+</pre>
+<p>
+Or select the x64 compiler:
+</p>
+<pre class="code">
+setenv /release /x64
+</pre>
+<p>
+Then <tt>cd</tt> to the directory where you've unpacked the sources
+and run these commands:
+</p>
+<pre class="code">
+cd src
+msvcbuild
+</pre>
+<p>
+Then follow the installation instructions below.
+</p>
+<h3>Building with MinGW or Cygwin</h3>
+<p>
+Open a command prompt window and make sure the MinGW or Cygwin programs
+are in your path. Then <tt>cd</tt> to the directory where
+you've unpacked the sources and run this command for MinGW:
+</p>
+<pre class="code">
+mingw32-make
+</pre>
+<p>
+Or this command for Cygwin:
+</p>
+<pre class="code">
+make
+</pre>
+<p>
+Then follow the installation instructions below.
+</p>
+<h3>Installing LuaJIT</h3>
+<p>
+Copy <tt>luajit.exe</tt> and <tt>lua51.dll</tt> (built in the <tt>src</tt>
+directory) to a newly created directory (any location is ok).
+Add <tt>lua</tt> and <tt>lua\jit</tt> directories below it and copy
+all Lua files from the <tt>src\jit</tt> directory of the distribution
+to the latter directory.
+</p>
+<p>
+There are no hardcoded
+absolute path names &mdash; all modules are loaded relative to the
+directory where <tt>luajit.exe</tt> is installed
+(see <tt>src/luaconf.h</tt>).
+</p>
+
+<h2 id="cross">Cross-compiling LuaJIT</h2>
+<p>
+First, let's clear up some terminology:
+</p>
+<ul>
+<li>Host: This is your development system, usually based on a x64 or x86 CPU.</li>
+<li>Target: This is the target system you want LuaJIT to run on, e.g. Android/ARM.</li>
+<li>Toolchain: This comprises a C compiler, linker, assembler and a matching C library.</li>
+<li>Host (or system) toolchain: This is the toolchain used to build native binaries for your host system.</li>
+<li>Cross-compile toolchain: This is the toolchain used to build binaries for the target system. They can only be run on the target system.</li>
+</ul>
+<p>
+The GNU Makefile-based build system allows cross-compiling on any host
+for any supported target:
+</p>
+<ul>
+<li>Yes, you need a toolchain for both your host <em>and</em> your target!</li>
+<li>Both host and target architectures must have the same pointer size.</li>
+<li>E.g. if you want to cross-compile to a 32 bit target on a 64 bit host, you need to install the multilib development package (e.g. <tt>libc6-dev-i386</tt> on Debian/Ubuntu) and build a 32 bit host part (<tt>HOST_CC="gcc -m32"</tt>).</li>
+<li>64 bit targets always require compilation on a 64 bit host.</li>
+</ul>
+<p>
+You need to specify <tt>TARGET_SYS</tt> whenever the host OS and the
+target OS differ, or you'll get assembler or linker errors:
+</p>
+<ul>
+<li>E.g. if you're compiling on a Windows or OSX host for embedded Linux or Android, you need to add <tt>TARGET_SYS=Linux</tt> to the examples below.</li>
+<li>For a minimal target OS, you may need to disable the built-in allocator in <tt>src/Makefile</tt> and use <tt>TARGET_SYS=Other</tt>.</li>
+<li>Don't forget to specify the same <tt>TARGET_SYS</tt> for the install step, too.</li>
+</ul>
+<p>
+Here are some examples where host and target have the same CPU:
+</p>
+<pre class="code">
+# Cross-compile to a 32 bit binary on a multilib x64 OS
+make CC="gcc -m32"
+
+# Cross-compile on Debian/Ubuntu for Windows (mingw32 package)
+make HOST_CC="gcc -m32" CROSS=i586-mingw32msvc- TARGET_SYS=Windows
+</pre>
+<p id="cross2">
+The <tt>CROSS</tt> prefix allows specifying a standard GNU cross-compile
+toolchain (Binutils, GCC and a matching libc). The prefix may vary
+depending on the <tt>--target</tt> the toolchain was built for (note the
+<tt>CROSS</tt> prefix has a trailing <tt>"-"</tt>). The examples below
+use the canonical toolchain triplets for Linux.
+</p>
+<p>
+Since there's often no easy way to detect CPU features at runtime, it's
+important to compile with the proper CPU or architecture settings:
+</o>
+<ul>
+<li>The best way to get consistent results is to specify the correct settings when building the toolchain yourself.</li>
+<li>For a pre-built, generic toolchain add <tt>-mcpu=...</tt> or <tt>-march=...</tt> and other necessary flags to <tt>TARGET_CFLAGS</tt>.</li>
+<li>For ARM it's important to have the correct <tt>-mfloat-abi=...</tt> setting, too. Otherwise LuaJIT may not run at the full performance of your target CPU.</li>
+<li>For MIPS it's important to select a supported ABI (o32 on MIPS32, n64 on MIPS64) and consistently compile your project either with hard-float or soft-float compiler settings.</li>
+</ul>
+<p>
+Here are some examples for targets with a different CPU than the host:
+</p>
+<pre class="code">
+# ARM soft-float
+make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabi- \
+     TARGET_CFLAGS="-mfloat-abi=soft"
+
+# ARM soft-float ABI with VFP (example for Cortex-A9)
+make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabi- \
+     TARGET_CFLAGS="-mcpu=cortex-a9 -mfloat-abi=softfp"
+
+# ARM hard-float ABI with VFP (armhf, most modern toolchains)
+make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabihf-
+
+# ARM64
+make CROSS=aarch64-linux-
+
+# PPC
+make HOST_CC="gcc -m32" CROSS=powerpc-linux-gnu-
+
+# MIPS32 big-endian
+make HOST_CC="gcc -m32" CROSS=mips-linux-
+# MIPS32 little-endian
+make HOST_CC="gcc -m32" CROSS=mipsel-linux-
+
+# MIPS64 big-endian
+make CROSS=mips-linux- TARGET_CFLAGS="-mips64r2 -mabi=64"
+# MIPS64 little-endian
+make CROSS=mipsel-linux- TARGET_CFLAGS="-mips64r2 -mabi=64"
+</pre>
+<p>
+You can cross-compile for <b id="android">Android</b> using the <a href="https://developer.android.com/ndk/index.html">Android NDK</a>.
+The environment variables need to match the install locations and the
+desired target platform. E.g. Android&nbsp;4.0 corresponds to ABI level&nbsp;14.
+For details check the folder <tt>docs</tt> in the NDK directory.
+</p>
+<p>
+Only a few common variations for the different CPUs, ABIs and platforms
+are listed. Please use your own judgement for which combination you want
+to build/deploy or which lowest common denominator you want to pick:

+<h3 id="consoles">Cross-compiling for consoles</h3>
+<p>
+Building LuaJIT for consoles requires both a supported host compiler
+(x86 or x64) and a cross-compiler (to PPC or ARM) from the official
+console SDK.
+</p>
+<p>
+Due to restrictions on consoles, the JIT compiler is disabled and only
+the fast interpreter is built. This is still faster than plain Lua,
+but much slower than the JIT compiler. The FFI is disabled, too, since
+it's not very useful in such an environment.
+</p>
+<p>
+The following commands build a static library <tt>libluajit.a</tt>,
+which can be linked against your game, just like the Lua library.

+<p>
+To cross-compile for <b id="ps3">PS3</b> from a Linux host (requires

+
+<h2 id="embed">Embedding LuaJIT</h2>
+<p>
+LuaJIT is API-compatible with Lua 5.1. If you've already embedded Lua
+into your application, you probably don't need to do anything to switch
+to LuaJIT, except link with a different library:
+</p>
+<ul>
+<li>It's strongly suggested to build LuaJIT separately using the supplied
+build system. Please do <em>not</em> attempt to integrate the individual
+source files into your build tree. You'll most likely get the internal build
+dependencies wrong or mess up the compiler flags. Treat LuaJIT like any
+other external library and link your application with either the dynamic
+or static library, depending on your needs.</li>
+<li>If you want to load C modules compiled for plain Lua
+with <tt>require()</tt>, you need to make sure the public symbols
+(e.g. <tt>lua_pushnumber</tt>) are exported, too:
+<ul><li>On POSIX systems you can either link to the shared library
+or link the static library into your application. In the latter case
+you'll need to export all public symbols from your main executable
+(e.g. <tt>-Wl,-E</tt> on Linux) and add the external dependencies
+(e.g. <tt>-lm -ldl</tt> on Linux).</li>
+<li>Since Windows symbols are bound to a specific DLL name, you need to
+link to the <tt>lua51.dll</tt> created by the LuaJIT build (do not rename
+the DLL). You may link LuaJIT statically on Windows only if you don't
+intend to load Lua/C modules at runtime.
+</li></ul>
+</li>
+<li>
+If you're building a 64 bit application on OSX which links directly or
+indirectly against LuaJIT which is not built for <tt>LJ_GC64</tt> mode,
+you need to link your main executable with these flags:
+<pre class="code">
+-pagezero_size 10000 -image_base 100000000
+</pre>
+</li>
+</ul>
+<p>Additional hints for initializing LuaJIT using the C API functions:</p>
+<ul>
+<li>Here's a
+<a href="http://lua-users.org/wiki/SimpleLuaApiExample"><span class="ext">&raquo;</span>&nbsp;simple example</a>
+for embedding Lua or LuaJIT into your application.</li>
+<li>Make sure you use <tt>luaL_newstate</tt>. Avoid using
+<tt>lua_newstate</tt>, since this uses the (slower) default memory
+allocator from your system (no support for this on x64).</li>
+<li>Make sure you use <tt>luaL_openlibs</tt> and not the old Lua 5.0 style
+of calling <tt>luaopen_base</tt> etc. directly.</li>
+<li>To change or extend the list of standard libraries to load, copy
+<tt>src/lib_init.c</tt> to your project and modify it accordingly.
+Make sure the <tt>jit</tt> library is loaded or the JIT compiler
+will not be activated.</li>
+<li>The <tt>bit.*</tt> module for bitwise operations
+is already built-in. There's no need to statically link
+<a href="http://bitop.luajit.org/"><span class="ext">&raquo;</span>&nbsp;Lua BitOp</a> to your application.</li>
+</ul>
+
+<h2 id="distro">Hints for Distribution Maintainers</h2>
+<p>
+The LuaJIT build system has extra provisions for the needs of most
+POSIX-based distributions. If you're a package maintainer for
+a distribution, <em>please</em> make use of these features and
+avoid patching, subverting, autotoolizing or messing up the build system
+in unspeakable ways.
+</p>
+<p>
+There should be absolutely no need to patch <tt>luaconf.h</tt> or any
+of the Makefiles. And please do not hand-pick files for your packages &mdash;
+simply use whatever <tt>make install</tt> creates. There's a reason
+for all of the files <em>and</em> directories it creates.
+</p>
+<p>
+The build system uses GNU make and auto-detects most settings based on
+the host you're building it on. This should work fine for native builds,
+even when sandboxed. You may need to pass some of the following flags to
+<em>both</em> the <tt>make</tt> and the <tt>make install</tt> command lines
+for a regular distribution build:
+</p>
+<ul>
+<li><tt>PREFIX</tt> overrides the installation path and should usually
+be set to <tt>/usr</tt>. Setting this also changes the module paths and
+the paths needed to locate the shared library.</li>
+<li><tt>DESTDIR</tt> is an absolute path which allows you to install
+to a shadow tree instead of the root tree of the build system.</li>
+<li><tt>MULTILIB</tt> sets the architecture-specific library path component
+for multilib systems. The default is <tt>lib</tt>.</li>
+<li>Have a look at the top-level <tt>Makefile</tt> and <tt>src/Makefile</tt>
+for additional variables to tweak. The following variables <em>may</em> be
+overridden, but it's <em>not</em> recommended, except for special needs
+like cross-builds:
+<tt>BUILDMODE, CC, HOST_CC, STATIC_CC, DYNAMIC_CC, CFLAGS, HOST_CFLAGS,
+TARGET_CFLAGS, LDFLAGS, HOST_LDFLAGS, TARGET_LDFLAGS, TARGET_SHLDFLAGS,
+TARGET_FLAGS, LIBS, HOST_LIBS, TARGET_LIBS, CROSS, HOST_SYS, TARGET_SYS
+</tt></li>
+</ul>
+<p>
+The build system has a special target for an amalgamated build, i.e.
+<tt>make amalg</tt>. This compiles the LuaJIT core as one huge C file
+and allows GCC to generate faster and shorter code. Alas, this requires
+lots of memory during the build. This may be a problem for some users,
+that's why it's not enabled by default. But it shouldn't be a problem for
+most build farms. It's recommended that binary distributions use this
+target for their LuaJIT builds.
+</p>
+<p>
+The tl;dr version of the above:
+</p>
+<pre class="code">
+make amalg PREFIX=/usr && \
+make install PREFIX=/usr DESTDIR=/tmp/buildroot
+</pre>
+<p>
+Finally, if you encounter any difficulties, please
+<a href="contact.html">contact me</a> first, instead of releasing a broken
+package onto unsuspecting users. Because they'll usually gonna complain
+to me (the upstream) and not you (the package maintainer), anyway.

+LuaJIT has been successfully used as a <b>scripting middleware</b> in
+games, appliances, network and graphics apps, numerical simulations,
+trading platforms and many other specialty applications. It scales from
+embedded devices, smartphones, desktops up to server farms. It combines
+high flexibility with <a href="http://luajit.org/performance.html"><span class="ext">&raquo;</span>&nbsp;high performance</a>
+and an unmatched <b>low memory footprint</b>.
+</p>
+<p>
+LuaJIT has been in continuous development since 2005. It's widely
+considered to be <b>one of the fastest dynamic language
+implementations</b>. It has outperformed other dynamic languages on many
+cross-language benchmarks since its first release &mdash; often by a
+substantial margin.
+</p>
+<p>
+For <b>LuaJIT 2.0</b>, the whole VM has been rewritten from the ground up
+and relentlessly optimized for performance. It combines a <b>high-speed
+interpreter</b>, written in assembler, with a <b>state-of-the-art JIT
+compiler</b>.
+</p>
+<p>
+An innovative <b>trace compiler</b> is integrated with advanced,
+SSA-based optimizations and highly tuned code generation backends.
+A substantial reduction of the overhead associated with dynamic languages
+allows it to break into the performance range traditionally reserved for
+offline, static language compilers.

+LuaJIT has only a single stand-alone executable, called <tt>luajit</tt> on
+POSIX systems or <tt>luajit.exe</tt> on Windows. It can be used to run simple
+Lua statements or whole Lua applications from the command line. It has an
+interactive mode, too.
+</p>
+
+<h2 id="options">Command Line Options</h2>
+<p>
+The <tt>luajit</tt> stand-alone executable is just a slightly modified
+version of the regular <tt>lua</tt> stand-alone executable.
+It supports the same basic options, too. <tt>luajit&nbsp;-h</tt>
+prints a short list of the available options. Please have a look at the
+<a href="http://www.lua.org/manual/5.1/manual.html#6"><span class="ext">&raquo;</span>&nbsp;Lua manual</a>
+for details.
+</p>
+<p>
+LuaJIT has some additional options:
+</p>
+
+<h3 id="opt_b"><tt>-b[options] input output</tt></h3>
+<p>
+This option saves or lists bytecode. The following additional options
+are accepted:
+</p>
+<ul>
+<li><tt>-l</tt> &mdash; Only list bytecode.</li>
+<li><tt>-s</tt> &mdash; Strip debug info (this is the default).</li>
+<li><tt>-g</tt> &mdash; Keep debug info.</li>
+<li><tt>-n name</tt> &mdash; Set module name (default: auto-detect from input name)</li>
+<li><tt>-t type</tt> &mdash; Set output file type (default: auto-detect from output name).</li>
+<li><tt>-a arch</tt> &mdash; Override architecture for object files (default: native).</li>
+<li><tt>-o os</tt> &mdash; Override OS for object files (default: native).</li>
+<li><tt>-e chunk</tt> &mdash; Use chunk string as input.</li>
+<li><tt>-</tt> (a single minus sign) &mdash; Use stdin as input and/or stdout as output.</li>
+</ul>
+<p>
+The output file type is auto-detected from the extension of the output
+file name:
+</p>
+<ul>
+<li><tt>c</tt> &mdash; C source file, exported bytecode data.</li>
+<li><tt>h</tt> &mdash; C header file, static bytecode data.</li>
+<li><tt>obj</tt> or <tt>o</tt> &mdash; Object file, exported bytecode data
+(OS- and architecture-specific).</li>
+<li><tt>raw</tt> or any other extension &mdash; Raw bytecode file (portable).
+</ul>
+<p>
+Notes:
+</p>
+<ul>
+<li>See also <a href="extensions.html#string_dump">string.dump()</a>
+for information on bytecode portability and compatibility.</li>
+<li>A file in raw bytecode format is auto-detected and can be loaded like
+any Lua source file. E.g. directly from the command line or with
+<tt>loadfile()</tt>, <tt>dofile()</tt> etc.</li>
+<li>To statically embed the bytecode of a module in your application,
+generate an object file and just link it with your application.</li>
+<li>On most ELF-based systems (e.g. Linux) you need to explicitly export the
+global symbols when linking your application, e.g. with: <tt>-Wl,-E</tt></li>
+<li><tt>require()</tt> tries to load embedded bytecode data from exported
+symbols (in <tt>*.exe</tt> or <tt>lua51.dll</tt> on Windows) and from
+shared libraries in <tt>package.cpath</tt>.</li>
+</ul>

+<h3 id="opt_j"><tt>-j cmd[=arg[,arg...]]</tt></h3>
+<p>
+This option performs a LuaJIT control command or activates one of the
+loadable extension modules. The command is first looked up in the
+<tt>jit.*</tt> library. If no matching function is found, a module
+named <tt>jit.&lt;cmd&gt;</tt> is loaded and the <tt>start()</tt>
+function of the module is called with the specified arguments (if
+any). The space between <tt>-j</tt> and <tt>cmd</tt> is optional.
+</p>
+<p>
+Here are the available LuaJIT control commands:
+</p>
+<ul>
+<li id="j_on"><tt>-jon</tt> &mdash; Turns the JIT compiler on (default).</li>
+<li id="j_off"><tt>-joff</tt> &mdash; Turns the JIT compiler off (only use the interpreter).</li>
+<li id="j_flush"><tt>-jflush</tt> &mdash; Flushes the whole cache of compiled code.</li>
+<li id="j_v"><tt>-jv</tt> &mdash; Shows verbose information about the progress of the JIT compiler.</li>
+<li id="j_dump"><tt>-jdump</tt> &mdash; Dumps the code and structures used in various compiler stages.</li>
+<li id="j_p"><tt>-jp</tt> &mdash; Start the <a href="ext_profiler.html">integrated profiler</a>.</li>
+</ul>
+<p>
+The <tt>-jv</tt> and <tt>-jdump</tt> commands are extension modules
+written in Lua. They are mainly used for debugging the JIT compiler
+itself. For a description of their options and output format, please
+read the comment block at the start of their source.
+They can be found in the <tt>lib</tt> directory of the source
+distribution or installed under the <tt>jit</tt> directory. By default
+this is <tt>/usr/local/share/luajit-2.0.5/jit</tt> on POSIX
+systems.
+</p>
+
+<h3 id="opt_O"><tt>-O[level]</tt><br>
+<tt>-O[+]flag</tt>&nbsp;&nbsp;&nbsp;<tt>-O-flag</tt><br>
+<tt>-Oparam=value</tt></h3>
+<p>
+This options allows fine-tuned control of the optimizations used by
+the JIT compiler. This is mainly intended for debugging LuaJIT itself.
+Please note that the JIT compiler is extremely fast (we are talking
+about the microsecond to millisecond range). Disabling optimizations
+doesn't have any visible impact on its overhead, but usually generates
+code that runs slower.
+</p>
+<p>
+The first form sets an optimization level &mdash; this enables a
+specific mix of optimization flags. <tt>-O0</tt> turns off all
+optimizations and higher numbers enable more optimizations. Omitting
+the level (i.e. just <tt>-O</tt>) sets the default optimization level,
+which is <tt>-O3</tt> in the current version.
+</p>
+<p>
+The second form adds or removes individual optimization flags.
+The third form sets a parameter for the VM or the JIT compiler
+to a specific value.
+</p>
+<p>
+You can either use this option multiple times (like <tt>-Ocse
+-O-dce -Ohotloop=10</tt>) or separate several settings with a comma
+(like <tt>-O+cse,-dce,hotloop=10</tt>). The settings are applied from
+left to right and later settings override earlier ones. You can freely
+mix the three forms, but note that setting an optimization level
+overrides all earlier flags.

+are enabled:

+<span style="color: #0000c0;">LuaJIT&nbsp;2.0</span> is the current
+<span style="color: #0000c0;">stable branch</span>. This branch is in
+feature-freeze &mdash; new features will only be added to LuaJIT&nbsp;2.1.
+</p>
+
+<h2>Current Status</h2>
+<p>
+LuaJIT ought to run all Lua&nbsp;5.1-compatible source code just fine.
+It's considered a serious bug if the VM crashes or produces unexpected
+results &mdash; please report this.
+</p>
+<p>
+Known incompatibilities and issues in LuaJIT&nbsp;2.0:
+</p>
+<ul>
+<li>
+There are some differences in <b>implementation-defined</b> behavior.
+These either have a good reason, are arbitrary design choices
+or are due to quirks in the VM. The latter cases may get fixed if a
+demonstrable need is shown.
+</li>
+<li>
+The Lua <b>debug API</b> is missing a couple of features (return
+hooks for non-Lua functions) and shows slightly different behavior
+in LuaJIT (no per-coroutine hooks, no tail call counting).
+</li>
+<li>
+Currently some <b>out-of-memory</b> errors from <b>on-trace code</b> are not
+handled correctly. The error may fall through an on-trace
+<tt>pcall</tt> or it may be passed on to the function set with
+<tt>lua_atpanic</tt> on x64. This issue will be fixed with the new
+garbage collector.
+</li>
+<li>
+LuaJIT on 64 bit systems provides a <b>limited range</b> of 47 bits for the
+<b>legacy <tt>lightuserdata</tt></b> data type.
+This is only relevant on x64 systems which use the negative part of the
+virtual address space in user mode, e.g. Solaris/x64, and on ARM64 systems
+configured with a 48 bit or 52 bit VA.
+Avoid using <tt>lightuserdata</tt> to hold pointers that may point outside
+of that range, e.g. variables on the stack. In general, avoid this data
+type for new code and replace it with (much more performant) FFI bindings.
+FFI cdata pointers can address the full 64 bit range.
+</li>

+-- x86 Template String Description
+-- ===============================
+--
+-- Each template string is a list of [match:]pattern pairs,
+-- separated by "|". The first match wins. No match means a
+-- bad or unsupported combination of operand modes or sizes.
+--
+-- The match part and the ":" is omitted if the operation has
+-- no operands. Otherwise the first N characters are matched
+-- against the mode strings of each of the N operands.
+--
+-- The mode string for each operand type is (see parseoperand()):
+--   Integer register: "rm", +"R" for eax, ax, al, +"C" for cl
+--   FP register:      "f",  +"F" for st0
+--   Index operand:    "xm", +"O" for [disp] (pure offset)
+--   Immediate:        "i",  +"S" for signed 8 bit, +"1" for 1,
+--                     +"I" for arg, +"P" for pointer
+--   Any:              +"J" for valid jump targets
+--
+-- So a match character "m" (mixed) matches both an integer register
+-- and an index operand (to be encoded with the ModRM/SIB scheme).
+-- But "r" matches only a register and "x" only an index operand
+-- (e.g. for FP memory access operations).
+--
+-- The operand size match string starts right after the mode match
+-- characters and ends before the ":". "dwb" or "qdwb" is assumed, if empty.
+-- The effective data size of the operation is matched against this list.
+--
+-- If only the regular "b", "w", "d", "q", "t" operand sizes are
+-- present, then all operands must be the same size. Unspecified sizes
+-- are ignored, but at least one operand must have a size or the pattern
+-- won't match (use the "byte", "word", "dword", "qword", "tword"
+-- operand size overrides. E.g.: mov dword [eax], 1).
+--
+-- If the list has a "1" or "2" prefix, the operand size is taken
+-- from the respective operand and any other operand sizes are ignored.
+-- If the list contains only ".", all operand sizes are ignored.
+-- If the list has a "/" prefix, the concatenated (mixed) operand sizes
+-- are compared to the match.
+--
+-- E.g. "rrdw" matches for either two dword registers or two word
+-- registers. "Fx2dq" matches an st0 operand plus an index operand
+-- pointing to a dword (float) or qword (double).
+--
+-- Every character after the ":" is part of the pattern string:
+--   Hex chars are accumulated to form the opcode (left to right).
+--   "n"       disables the standard opcode mods
+--             (otherwise: -1 for "b", o16 prefix for "w", rex.w for "q")
+--   "X"       Force REX.W.
+--   "r"/"R"   adds the reg. number from the 1st/2nd operand to the opcode.
+--   "m"/"M"   generates ModRM/SIB from the 1st/2nd operand.
+--             The spare 3 bits are either filled with the last hex digit or
+--             the result from a previous "r"/"R". The opcode is restored.
+--   "u"       Use VEX encoding, vvvv unused.
+--   "v"/"V"   Use VEX encoding, vvvv from 1st/2nd operand (the operand is
+--             removed from the list used by future characters).
+--   "w"       Use VEX encoding, vvvv from 3rd operand.
+--   "L"       Force VEX.L
+--
+-- All of the following characters force a flush of the opcode:
+--   "o"/"O"   stores a pure 32 bit disp (offset) from the 1st/2nd operand.
+--   "s"       stores a 4 bit immediate from the last register operand,
+--             followed by 4 zero bits.
+--   "S"       stores a signed 8 bit immediate from the last operand.
+--   "U"       stores an unsigned 8 bit immediate from the last operand.
+--   "W"       stores an unsigned 16 bit immediate from the last operand.
+--   "i"       stores an operand sized immediate from the last operand.
+--   "I"       dito, but generates an action code to optionally modify
+--             the opcode (+2) for a signed 8 bit immediate.
+--   "J"       generates one of the REL action codes from the last operand.

+.SH NAME
+luajit \- Just-In-Time Compiler for the Lua Language
+\fB
+.SH SYNOPSIS
+.B luajit
+[\fIoptions\fR]... [\fIscript\fR [\fIargs\fR]...]
+.SH "WEB SITE"
+.IR http://luajit.org
+.SH DESCRIPTION
+.PP
+This is the command-line program to run Lua programs with \fBLuaJIT\fR.
+.PP
+\fBLuaJIT\fR is a just-in-time (JIT) compiler for the Lua language.
+The virtual machine (VM) is based on a fast interpreter combined with
+a trace compiler. It can significantly improve the performance of Lua programs.
+.PP
+\fBLuaJIT\fR is API\- and ABI-compatible with the VM of the standard
+Lua\ 5.1 interpreter. When embedding the VM into an application,
+the built library can be used as a drop-in replacement.
+.SH OPTIONS
+.TP
+.BI "\-e " chunk
+Run the given chunk of Lua code.
+.TP
+.BI "\-l " library
+Load the named library, just like \fBrequire("\fR\fIlibrary\fR\fB")\fR.
+.TP
+.BI "\-b " ...
+Save or list bytecode. Run without arguments to get help on options.
+.TP
+.BI "\-j " command
+Perform LuaJIT control command (optional space after \fB\-j\fR).
+.TP
+.BI "\-O" [opt]
+Control LuaJIT optimizations.
+.TP
+.B "\-i"
+Run in interactive mode.
+.TP
+.B "\-v"
+Show \fBLuaJIT\fR version.
+.TP
+.B "\-E"
+Ignore environment variables.
+.TP
+.B "\-\-"
+Stop processing options.
+.TP
+.B "\-"
+Read script from stdin instead.
+.PP
+After all options are processed, the given \fIscript\fR is run.
+The arguments are passed in the global \fIarg\fR table.
+.PP
+Interactive mode is only entered, if no \fIscript\fR and no \fB\-e\fR
+option is given. Interactive mode can be left with EOF (\fICtrl\-Z\fB).
+.SH EXAMPLES
+.TP
+luajit hello.lua world
+
+Prints "Hello world", assuming \fIhello.lua\fR contains:
+.br
+  print("Hello", arg[1])
+.TP
+luajit \-e "local x=0; for i=1,1e9 do x=x+i end; print(x)"
+
+Calculates the sum of the numbers from 1 to 1000000000.
+.br
+And finishes in a reasonable amount of time, too.
+.TP
+luajit \-jv \-e "for i=1,10 do for j=1,10 do for k=1,100 do end end end"
+
+Runs some nested loops and shows the resulting traces.

+#
+# Since the assembler part does NOT maintain a frame pointer, it's pointless

+#XCFLAGS+= -DLUAJIT_DISABLE_FFI
+#
+# Features from Lua 5.2 that are unlikely to break existing code are

+############################  DEBUGGING SUPPORT  #############################
+##############################################################################
+# Enable these options as needed, but make sure you force a full recompile
+# with "make clean", followed by "make".
+# Note that most of these are NOT suitable for benchmarking or release mode!
+#
+# Use the system provided memory allocator (realloc) instead of the
+# bundled memory allocator. This is slower, but sometimes helpful for
+# debugging. This option cannot be enabled on x64 without GC64, since
+# realloc usually doesn't return addresses in the right address range.
+# OTOH this option is mandatory for Valgrind's memcheck tool on x64 and
+# the only way to get useful results from it for all other architectures.
+#XCFLAGS+= -DLUAJIT_USE_SYSMALLOC
+#
+# This define is required to run LuaJIT under Valgrind. The Valgrind
+# header files must be installed. You should enable debug information, too.
+# Use --suppressions=lj.supp to avoid some false positives.
+#XCFLAGS+= -DLUAJIT_USE_VALGRIND
+#
+# This is the client for the GDB JIT API. GDB 7.0 or higher is required
+# to make use of it. See lj_gdbjit.c for details. Enabling this causes
+# a non-negligible overhead, even when not running under GDB.
+#XCFLAGS+= -DLUAJIT_USE_GDBJIT
+#
+# Turn on assertions for the Lua/C API to debug problems with lua_* calls.
+# This is rather slow -- use only while developing C libraries/embeddings.
+#XCFLAGS+= -DLUA_USE_APICHECK
+#
+# Turn on assertions for the whole LuaJIT VM. This significantly slows down
+# everything. Use only if you suspect a problem with LuaJIT itself.
