Re: PROPOSAL: targetm.expand_tree_builtin hook


Something akin to this I proposed for re-doing Altivec builtins.

http://gcc.gnu.org/ml/gcc-patches/2004-04/msg00791.html

I'm doing something very similar but based on a fold_builtin hook, only because I started my AltiVec work about at the same time as Richard prepared that RFC.


fold_builtin seems to be not too late in the game, and anyway it would be easy to convert to something like the expand_tree_builtin hook you propose.

Aside from that, I think it would be great if you could commit
this functionality!  Can you? :-)

It is not complete, it should be extracted from the patch, and renamed as you suggested.


Or, I can send you my patch for a fold_builtin target hook.
