[PATCH] D62604: [CodeGen] Generic Hardware Loop Support

[Sam Parker via Phabricator via llvm-commits]

samparker updated this revision to Diff 202702.
samparker added a comment.

- Added comments describing the intrinsics.
- loop_decrement now just returns an i1, instead of being declared anyint. This allowed removing some changes from PPC backend.
