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

[Alexey Lapshin via Phabricator via llvm-commits]

alexey.lapshin added a comment.

Michael, I evaluated what should be done to implement warnings about missed transformations for pragma clang loop pipeine. It requires modifications for WarnMissedTransformations pass or creating another one which will work after MIR generated, it would also be neccessary to change metadata handling in MachinePipeliner.cpp. I am OK to do all of these. Though I would prefer to do it as a separate patch.

Would it be OK to integrate this patch in it`s current state and create another patch for warning about missed transformation for #pragma clang loop pipeline ?
