For some reason, the pshufb instruction does not work on my
AMD Athlon 64. I tried it in 32 bit mode, and I get an illegal
instruction message from Windows.
According to this:

it should support SSE3.
Any ideas why pshufb doesn't work?
Can you post the binary or hex encoding of the pshufb instruction that is
causing the illegal instruction exception?

It is the following five bytes:
0x66
0x0F
0x38
0x00
0xC1
All the google searches I've done on pshufb indicate that this instruction is SSE4.
