[PATCH] D106891: [AMDGPU] [Remarks] Emit optimization remarks when an FP atomic instruction is converted into a CAS loop or unsafe hardware instruction for GFX90A

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

If you insist on making this a target remark (which I don't think it should be, and don't think it should be too specific about why the expansion happened), you have to pass through the ORE to the callback
