Needs test.



================
Comment at: llvm/lib/Target/AMDGPU/GCNSubtarget.h:594
   bool d16PreservesUnusedBits() const {
-    return hasD16LoadStore() && !TargetID.isSramEccOnOrAny();
+    // gff90a's d16 loads don't preserve unused bits
+    return hasD16LoadStore() && !TargetID.isSramEccOnOrAny() &&
----------------
Typo gff90a.
