Hi, Because of my work, I need to prevent glibc from using SSE3 routine such as __strncpy_ssse3 even though the machine supports those features. My current solution is to recompile glibc from source rpm. However, I am not sure if there is a flag that I add into the spec to do what I want. There seems to be --host option of 32-bit that allow me to target specific CPU (i[345]86) but I don't see if there is a similar option for x86_64 machine.
