Can not disable sse in gcc

Question

I am trying to disable sse and sse2 instructions. I am cross compiling for x86 in a x64 system. I am also using -static to statically link with libc. Although I use -mno-sse and -mno-sse2, when I disassemble the binary I still see a call to strcpy_sse2, any solution?

Answer 1

It is highly possible that your library still contains sse instructions. You will have to build the library for your cross system as well and do that without sse instructions.

Answer 2

For 64 bit Use -mno-sse gcc option
