Renamed lib to deps so github will ignore it for language stats

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> +</ul> +<br class="flush"> +</div> +<div id="foot"> +<hr class="hide"> +Copyright © 2005-2018 +<span class="noprint"> +· +<a href="contact.html">Contact</a> +</span> +</div> +</body> +</html> |
