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.
------- Comment #1 From Andrew Pinski 2005-02-18 04:50 [reply] ------- Well this builtin function now has been removed. ------- Comment #2 From Kelley Cook 2005-04-20 18:03 [reply] ------- The obvious typo in the docs would still apply to 3.x though. 4.x has the seperate issue that the following functions are no longer available (I assume intentionally, though it really wasn't announced) yet still documented: __builtin_ia32_loadaps __builtin_ia32_loadddup __builtin_ia32_loadsss [__builtin_ia32_loadss] __builtin_ia32_movddup __builtin_ia32_pextrw __builtin_ia32_pfrsqrtit1 __builtin_ia32_pinsrw __builtin_ia32_storeaps __builtin_ia32_storess
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.
