Re: [Haskell-cafe] Re: Haskell version of ray tracer code is much slower than the original ML

-fvia-C -fexcess-precision -optc-mfpmath=sse2

is there, or should there be a way to define -O "profiles" for ghc? so that -O would refer to the standard profile, -Ofp would refer to the combination above as a floating point optiimisation profile, other profiles might include things like -funbox-strict-fields, and -Omy42 would refer to my own favourite combination of flags.. perhaps this should be generalised to ghc flag profiles, to cover things like '-fno-monomorphism-restriction -fno-mono-pat-binds' or '-fglasgow-exts -fallow-undecidable-instances; and the like? just a thought, claus
