I looked into this, and I don't think my patch changes the situation for value profiling. PGO instrumentation is performed early. Before my patch it would see a call to `@llvm.coro.resume`, and now it will see `@llvm.coro.await.suspend.handle`. In neither case does it see the lowered indirect call to the resumed function, and so no `@llvm.instrprof.value.profile` call gets inserted. Supporting that would be a nice future improvement. https://github.com/llvm/llvm-project/pull/89751 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
