arsenm added inline comments.
================
Comment at: llvm/tools/clang/lib/Basic/Targets.cpp:2114-2116
+ static bool hasFullSpeedFP32Denorms(StringRef GPUName) {
+ return parseAMDGCNName(GPUName) >= GK_GFX9;
+ }
----------------
This is misleading since it was true on VI as well. I think just FMA rate changed
