RolandF added inline comments.
================
Comment at: llvm/lib/Target/PowerPC/PPC.td:320
+def FeatureCheapMFLR :
+ SubtargetFeature<"cheap-MFLR", "CheapMFLR", "true", "Enable cheap MFLR">;
+
----------------
I would suggest fast-MFLR rather than cheap-MFLR, and for the description I would suggest "MFLR is a fast instruction"
================
Comment at: llvm/lib/Target/PowerPC/PPCSubtarget.h:442
+ bool isCheapMFLR() const {
+ return CheapMFLR;
+ }
----------------
As this function has only a return, it can be a one line function and be put with the other one line functions.
