For some reason, the pshufb instruction does not work on my

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
Sandpile.org says pshufb is *Supplemental* SSE3 (SSSE3) which is a follow-on to
SSE3.

Okay. It looks like it is SSSE3.
