[PATCH] D81728: [InstCombine] Add target-specific inst combining

[Jay Foad via Phabricator via cfe-commits]

foad added inline comments.


================
Comment at: llvm/include/llvm/Analysis/TargetTransformInfo.h:552-555
+  /// \returns false to not do anything target specific or true to return the
+  /// value in \p ResultI from the InstCombiner. It is possible to return null
+  /// and stop further processing of the intrinsic by writing nullptr into
+  /// \p ResultI and returning true.
----------------
Did you consider returning `std::pair<bool,Instruction*>`?
