[PATCH] D64595: [Debuginfo][SROA] Need to handle dbg.value in SROA pass.

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

There's a lot of text here, I'm sorry I haven't read it all, but I think we should try to avoid getting in this situation where dbg.value points to an alloca in the first place. In Chromium, we use -instcombine-lower-dbg-declare to prevent instcombine from conservatively demoting from the "high availability" dbg.declare to the "always accurate but often missing" dbg.value. I don't really have time to work on this or participate in the discussion, so I'll just drop my two cents in and run away... =S
