[PATCH] D88684: llvm-reduce: Don't replace intrinsic calls with undef

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

what sort of problems manifest from this issue? Does it lead to slower reductions because they spend more time creating a lot of broken reductions?

I worry a bit about using heuristics "some intrinsics have these properties, so let's ignore all intrinsics" - other intrinsics represent normal instruction operations, right? (for target intrinsic instructions, for instance) so some cases might benefit from such reductions.
