[PATCH] D108741: [IR][GlobalDCE] Extend !vcall_visibility to be able to specify an offset range that it applies to

[John McCall via Phabricator via llvm-commits]

rjmccall added a comment.

I think Peter is saying that if you can make Clang emit correct ranges for v-tables — specifically so that the ranges don't cover the type_info pointer, which we don't emit enough metadata to safely remove — then you can also go ahead and remove the special case where we only eliminate loads of function pointers.  That's assuming we don't need to support old bitcode.
