hi there,
i tried compiling gsl with the flags
-march=pentium4 -mfpmath=sse -msse2
on gcc-3.2.1, and all seemed to work, the make checks all passed also
and my programs have no difference in their outputs
i think this is something which would really benefit people if they have
a P4 (and therefore sse2), as my own tests show that on double
arithmetic the performance is increased by 33% moving up to the sse2
instructions from the older 387 chip. maybe this could be encorporated
into the configure script to add these flags if a P4 is detected?
cheers,
Sam
