[PATCH] D98899: [DAE] Adjust param/arg attributes when changing parameter to undef

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

This looks reasonable to me. Dropping nonnull is not strictly necessary (because it has no immediate UB), but doesn't hurt either.

I was going to suggest using AttrBuilder to drop all attributes at once, but I'm not sure that works with dereferenceable attributes.
