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.
