<span style="color: #0000c0;">LuaJIT 2.0</span> is the current
|
|
<span style="color: #0000c0;">stable branch</span>. This branch is in
|
|
feature-freeze — new features will only be added to LuaJIT 2.1.
|
|
</p>
|
|
|
|
<h2>Current Status</h2>
|
|
<p>
|
|
LuaJIT ought to run all Lua 5.1-compatible source code just fine.
|
|
It's considered a serious bug if the VM crashes or produces unexpected
|
|
results — please report this.
|
|
</p>
|
|
<p>
|
|
Known incompatibilities and issues in LuaJIT 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>
|
|
Some checks are missing in the JIT-compiled code for obscure situations
|
|
with <b>open upvalues aliasing</b> one of the SSA slots later on (or
|
|
vice versa). Bonus points, if you can find a real world test case for
|
|
this.
|
|
</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>
|
|
</ul>
|
|
