Comment (by vbraun):
popcnt is SSE4.2, so Core 2 Duo don't have it. Btw on Linux I can do
{{{
[~]$ objdump -d sage/local/lib/libmpir.so | grep popcnt
45200: f3 4c 0f b8 04 cf popcnt (%rdi,%rcx,8),%r8
45206: f3 4c 0f b8 4c cf 08 popcnt 0x8(%rdi,%rcx,8),%r9
[...]
}}}
and I believe the equivalent command on OSX would be `otool -tV`.
Shouldn't we add some script to `sage -bdist` that checks for the absence
of, say, SSE >= 4 instructions?
