[PATCH] D78268: [Attributor] Deduce load/store alignment only in CGSCC passes

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Sorry for hijacking: Do you have any more information on where we make use of alignment information? Is it just in the backend, or also before that? (I'm wondering because one of the most expensive parts of InstCombine is known bits based alignment computation, maybe that should be moved from there into something like CGP, if it's not actually needed early...)
