[PATCH] D56403: add pragmas to control Software Pipelining optimisation

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added a comment.

I recently added a WarnMissedTransformationsPass (lib/Transforms/Scalar/WarnMissedTransformations.cpp) which emits a warning if a `#pragma clang loop` has not been applied, for any reason. It would be nince if it would work for `#pragma clang loop` as well. For instance, if the target backend does not support yet. My implementation is located after the midend loop  passes, so it cannot be adapted directly.
