Where is the built-in functions for SSE2 ?

[Jiang Alan]

I find the built-in functions for Intel SSE and MMX instruction set in GCC 
3.2.2 from 
http://gcc.gnu.org/onlinedocs/gcc-3.2.2/gcc/X86-Built-in-Functions.html#X86%20Built-in%20Functions.

But I cannot find the built-in functions for Intel SSE2 instruction set. 
Where is it? Why does it not appear in the formal document? Just lack of 
time to write the document or has not been implemented just? If the answer 
is the latter, when will them been implemented? In GCC 3.3 or 3.4 ?
