Diego Novillo - Re: TREE_ADDRESSABLE and trivial dead stores before inlining (original) (raw)

This is the mail archive of the gcc-patches@gcc.gnu.orgmailing list for the GCC project.

Well, it depends if we decide that aliasing with VOPS at IPA is what we want, that don't seem quite clear to me still, but lets give it a try. (my view of those two passes is to allow fast cleanup before we go to full aliasing so the unnecesary datastructures don't need to be built. It seems to pay back in compile times as we tested tonight on C++ tester. It is however possible that doing aliasing early will help too since we don't need to duplicate effort after inlining).
