Re: L2: Lua compiler in the works

["Humberto S. N. dos Anjos" <h.anjos@...>]

Right now:

- constant folding (already present) and propagation, dead code elimination, copy propagation and inlining;
- some loop optimizations (fusion, unrolling, invariant code motion);
- and some SSA-based optimizations.

There aren't much static optimizations to do at the bytecode level, other than write a decent code generator.

What kind of optimizations are you planning on?

My interest would be comparing this to LuaJIT and on the other hand
to what token filters / macros would allow.
