================
Comment at: llvm/lib/Target/AVR/AVRISelLowering.cpp:1878
+  // zero the bottom registers.
+  while (ShiftLeft && ShiftAmt >= 8) {
+    // Move all registers one to the left.
----------------
This can be `for (; ShiftLeft && ShiftAmt >= 8; ShiftAmt -= 8)` as you did in the next loop.

You can change that while committing.
