See comment #1, which points at patch written by HJ, which needs some
more work, and probably also a formal review.
As far as I know, the intrinsics are only defined in the Intel compiler
documentation. That is the list HJ is working from. As I understand
it, there is an intrinsic defined for every IA-64 instruction. Thus any
gcc extended asm can be converted into intrinsic calls. If you know the
naming scheme, you can probably generate your own list from IA-64
architecture documentation.
There was also two threads in the gcc list started by Jan Beulich here
http://gcc.gnu.org/ml/gcc/2005-01/msg00204.html
http://gcc.gnu.org/ml/gcc/2005-01/msg00276.html
I don't think he was volunteering to do the work, but he did point out
some issues that need to be considered, such as how vectors should be
treated as arguments and parameters.
