Deprecated SSE Builtins?

[Balint Joo]

Dear All,
	I note from a comment on bug ID 20049

(link: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20049 )

that certain SSE related builtin functions have been removed
from GCC as of version 4.0. I quote from the comments on the bug report
which merely noted that loadss was spelled loadsss in the documentation.

We have some code, which uses these builtins, especially the
loadaps, loadss and storeaps. Not being able to find the builtins is
stopping us from moving from gcc-3.x series to the gcc-4.x series.

Could anyone suggest alternative functionality that we could use?
Should we be considering inline assembler, ro rewrite these
routines or is there a better way? I tried to RTFM, but
as the very same bug report shows, it has not been updated
to cover the deprecation. Googling didn't help me much either.

If there is a new way, is it backward compatible with gcc-3.x series? The
best would be a way that is also portable to a recent Intel C++ compiler too.
  That would really help us.

I would appreciate any help on this issue.
	With best wishes,
