[PATCH] D120337: [InstCombine] Remove one-use limitation from X-Y==0 fold

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

It looks like this also causes a 7% code-size regression on tramp3d-v4: https://llvm-compile-time-tracker.com/compare.php?from=79353f940cf441e69f32af0a78a48baee89e8517&to=65dc78d63ee2eb20fbed54401091f08a685ef8c1&stat=size-text

So yeah, this clearly has some negative interactions that need to be addressed.
