Question about gcc's x86 builtin functions

Hi again,

I know this is a bit off-topic *sorry* - however I hope I don't bother
anybody with this question here since its almost exclusivly a gcc
C-backend question.

Gcc does provide access to SSE/3Dnow operations through so called
x86-buitin functions, however by reading the documentation I found out
that a lot operations are missing.
(e.g. the "packed shift right logical doubleword" called psrld).
Is just the documentation incomplete or is this functionality not
accesibly be gcc?

Seems I simply don't get it ;-)

Thank you in advance, lg Clemens
