Description Kirk Korver 2005-02-18 04:32:36 UTC 
If you look at http://www.dis.com/gnu/gcc/X86-Built-in-Functions.html, you will
find the following statement:

......
The following built-in functions are available when -msse is used.

v4sf __builtin_ia32_loadaps (float *)
    Generates the movaps machine instruction as a load from memory.
void __builtin_ia32_storeaps (float *, v4sf)
    Generates the movaps machine instruction as a store to memory.
v4sf __builtin_ia32_loadups (float *)
    Generates the movups machine instruction as a load from memory.
void __builtin_ia32_storeups (float *, v4sf)
    Generates the movups machine instruction as a store to memory.
v4sf __builtin_ia32_loadsss (float *)
    Generates the movss machine instruction as a load from memory. 
.......

This last line is incorrect. The correct function would be

v4sf __builtin_ia32_loadss (float *)

Notice that there are only 2 's' at the end, while the incorrect documentation
has 3 's'

Thank you for your time.
Sincerely,
Kirk Korver

Well this builtin function now has been removed.
Comment 2 Kelley Cook 2005-04-20 18:03:12 UTC 
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
