[PATCH] D106891: [AMDGPU] [Remarks] Emit optimization remarks for FP atomics

[Stanislav Mekhanoshin via Phabricator via cfe-commits]

rampitec added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIISelLowering.cpp:12146
+        OptimizationRemark Remark(DEBUG_TYPE, "Passed", RMW->getFunction());
+        Remark << "A floating-point atomic instruction will generate an unsafe"
+                  " hardware instruction";
----------------
It would not necessarily generate a HW instruction. There are still cases where we return CmpXChg.
