I didn't see any mentioning about it here so i thought I'd suggest making some benchmarks with llvmc/llvm-gcc/clang
llvm is really turning out great, and works for alot
I was going to test it myself, but i ran into some issues. Some of the tests even ignore the CC variable, making it very tricky to change the compiler, the others met with some issues with llvm itself.
Also, running things through lli, requires both compilation flags to be added (-emit-llvm -c -o foo.bc), and execution through lli foo.bc
