My platform is AMD x86-64. Does anyone know what's the option in gcc can only use the general registers not the media registers?
AFAIK, there are some switches you can use with GCC: -march:SSE2 and so on. What exactly do you mean "media registers": MMX or SSE ones?
But I want compiler only to use the general purpose registers. Don't use any XMM or MMX registers.
well compiling only for i386 should work. but why do you want that it donot use that registers? if you inline assembly you can specify which register you will use.
