[PATCH] D28694: Hexagon-specific loop idiom recognition

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added inline comments.


================
Comment at: lib/Transforms/IPO/PassManagerBuilder.cpp:320
+  addExtensionsToPM(EP_LoopIdiom, MPM);
+
   MPM.add(createLoopIdiomPass());             // Recognize idioms like memset.
----------------
This extension point could get its own separate patch.

It seems very targeted, if the only point is to have TargetSpecific loop idiom recognition, then why aren't some TTI implemented and used in LoopIdiomPass?
