[PATCH] D152059: [AVR] Replace shift-to-loop IR pass with common shift code

[Ben Shi via Phabricator via llvm-commits]

benshi001 added inline comments.


================
Comment at: llvm/lib/Target/AVR/AVRISelLowering.cpp:2219
+  // Shift the registers by one.
+  insertMultibyteShift(LoopBB->end(), LoopBB, dl, PhiRegPairs, Opc, 1);
+
----------------
Will the field `second` of `PhiRegPairs` be over written to `sub_lo` or `sub_hi` by `insertMultibyteShift` ?
