[PATCH] D130076: [llvm/CodeGen] Enable the ExpandLargeDivRem pass for X86, Arm and AArch64

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/include/llvm/Analysis/TargetTransformInfo.h:690-691
 
+  /// Returns the maximum bitwidth of legal div and rem instructions.
+  unsigned maxLegalDivRemBitWidth() const;
+
----------------
TargetTransformInfo isn't really the appropriate place to put something for a lowering decision. TargetLowering would make more sense
