< 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.

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.

Known incompatibilities and issues in LuaJIT 2.0:

There are some differences in < b > implementation-defined< / b > behavior.
These either have a good reason, are arbitrary design choices
2009-12-08 18:46:35 +00:00
or are due to quirks in the VM. The latter cases may get fixed if a
demonstrable need is shown.

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).

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.

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

2012-10-24 11:09:06 +00:00
< tt > lua_atpanic< / tt > on x64. This issue will be fixed with the new
garbage collector.
