I am going to look into this some more since well PPC/Cell/PS3 is my thing now.

I have a start to this patch and it works nicely, I just have to finish up
marking which builtins should be pure and which should be const and which are
neither.

My patch for this needs to be rewritten, not because it was wrong but because
it can be cleaned up.

Note this patch does not fully work as it marks vec_mtvscr as being constant
which it is not.

------- Comment #7 from pinskia at gcc dot gnu dot org 2008-03-12 20:42 -------
So what is happening is we don't model the SAT bit of VSCR on the tree level
(in the builtins) so the saturated builtins cannot be marked as const. They
are modeled correctly at the RTL level though.

Patches checked in on October 15th, 2009 to properly set pure/const.
