minimum to be done: -march=x86-64 i think x86 64 bits have minimum sse2 -mfpmath=sse2 -msse2 -funroll-all-loops -fomit-frame-pointer -ffast-math could be nice if more optimization can be done --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
