Hi Diego,
Several months ago, you mentioned that the alias analysis in gcc would be overhauled. Has this happened yet? If not, I am thinking about working on alias.c and tree-ssa-alias.c as there are only a handful of VARRAY uses left.It's happening in the mem-ssa branch. But switching from VARRAY to VEC will probably not affect my work, so go ahead. I guess that's what you have in mind? Switching VARRAY to VEC?
Yes, thanks! Kazu Hirata
