disabling sse3/sse4 in libc

[Akanksha Jain]

Hi,

I would like to disable all SSE3/4 versions of functions in glibc. I
am doing some experiments with a micro-architectural simulator which
does not have support for SSE3 and 4. In order for my simulator to
execute the program, the executable should be devoid of any SSE3/4
instructions.  My understanding is that the functions are chosen in
the library based on the CPUID. Is there a way I can disable SSE3/4 or
pass a non-native CPUID?

Thanks in advance!
