It may not be an issue w/ the compiler as much as w/  gas. (I may be wrong, I
don't do asm programming, the only asm I ever learned was a piece of machine
code for rebooting a computer when in virtual or real mode). Still, if gas
doesn't recognize the SSE instructions, then it won't like it. AFAIK, gcc
simply copies(emits??) the inline assembly into the resultant .S file fed into
as.

GAS is a separate pkg from gcc, IIRC it's part of binutils. The current
version is 2.91.xx (not sure what the xx is, it may even be a 2.91.xx.xx).
Other asm gurus will be able to give a more complete answer to your q then I
can.
