I’ve been excited about LLVM being low enough to model any system,
and saw it as promising that Apple was adopting it; but then again Apple doesn’t specifically support Haskell;
And, some think that Haskell would be better off with C–:
That LLVM’ers haven’t solved the problem of zero-overhead garbage collection
isn’t too surprising.
Solving this while staying agnostic of the data model
is an open question in computer science.
Well, there is a project at UNSW to translate GHC Core to LLVM
Remember: it wasn’t clear 10 years ago that LLVM would build up all the infrastructure C– wasn’t able to. Unfortunately, LLVM has the infrastructure for portable, optimized code, but not the infrastructure for nice high level language support, that C– ha(s)d.
An interesting project would be to target LLVM from C– …
Update, as of GHC 7, GHC uses LLVM for code generation. Use the
-fllvmflag. This has improved numerical performance for some low level programs. Otherwise, performance is similar to the old GCC backend.
