[PATCH] D80458: [AArch64][GlobalISel] Enable extending loads combines post-legalization.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/GlobalISel/CombinerHelper.h:99-103
+  bool matchCombineExtendingLoads(MachineInstr &MI, PreferredTuple &MatchInfo,
+                                  bool EnableAnyExt = true);
+  bool matchCombineExtendingLoadsNoAnyExt(MachineInstr &MI,
+                                          PreferredTuple &MatchInfo);
   void applyCombineExtendingLoads(MachineInstr &MI, PreferredTuple &MatchInfo);
----------------
This should just fix the combiner to understand checking for legal loads rather than special casing anyext?
