Re: L2: Lua compiler in the works

["Fabio Mascarenhas" <mascarenhas@...>]

Humberto, not to mention that LLVM's target is native code and yours is the Lua VM. :) An Lua-to-LLVM JIT is a lot of work, even if you reuse some parts of the Lua interpreter (garbage collector, layout of values, most of the standard library). 

A simpler application of LLVM is dynamically generating native code from Lua, like Javier's binding to TinyCC. LLVM is pretty easy to embed, and the native code it generates is comparable to gcc's -O3.

Maybe, but this is for my master's, so I'm supposed to do the optimizations myself :)

Would writing a front end to LLVM accomplish what you want?  Its a
compiler that can do both compile time and run time optimization
through running its 'bytecode' in a jit.  I have never used it, only
looked at it, but it seems interesting enough.

http://www.llvm.org is the URL.
