It wasn't actually compiling code, it was more a scheme-like assembly language which got far enough to run useful bits of code. We also had a lightning interface before the LLVM thing. > > But Matthew's effort on jitting via gnu lightning was better and > > so the llvm project was abandoned. Matthew actually wrote a jitter for bytecode, and lightning turned out fine for that. LLVM has a nice interface and lots of optimizations (some tied to how it represents assembly code) -- but the system itself is pretty big, which made it much less appealing as a target for jitting. (It's roughly like swallowing GCC into Racket.) > Interesting; I wasn't aware of GNU lightning. > > Does that mean that mzc currently targets lightning, or is that just > used in the JIT? Both of these are unrelated to mzc -- and the current use of lightning is only for jitting. If you're talking about using the LLVM C compiler, then that's a different issue (and I think that some people have tried that, but I don't remember who or whether it was successful). -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
