Comment(by dterei):
I know this is closed but just thought I would add the results these days:
{{{
ghc -O2 -optlo-O3 -fllvm Hash c_hash.c
}}}
{{{
Hash h 10: 0.29s | Hash c 10: 0.38s
Hash h 50: 0.97s | Hash c 50: 1.02s
Hash h 100: 1.94s | Hash h 100: 2.04s
}}}
I guess we could change this to fixed now instead of wontfix :).
