[PATCH] D85197: GlobalISel: Implement fewerElementsVector for G_CONCAT_VECTORS sources

[Amara Emerson via Phabricator via llvm-commits]

aemerson added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/LegalizerHelper.cpp:253
   for (int I = 0; I != NumResults; ++I)
-    Regs[I] = MI.getOperand(I).getReg();
+    Regs[StartIdx + I] = MI.getOperand(I).getReg();
 }
----------------
Why these changes to this function? The new behavior doesn't match the comment for it.
