[PATCH] D93039: Introduce llvm.noalias.decl intrinsic

[Jeroen Dobbelaere via Phabricator via llvm-commits]

jeroen.dobbelaere added a comment.

Another observation/question I have is about possible optimizations for omitting the `@llvm.experimental.noalias.scope.decl`: In the full restrict patches, the declarations are thrown away when there are no users any more. The equivalent with the implementation here, is that we can throw away the declaration if the scope it declares is not used in any `!alias.scope` metadata. Would this be something that is easy (and fast) to check ?
