[PATCH] D60690: [AArch64] Skip mask checks for masks with an odd number of elements.

[Gerolf Hoflehner via Phabricator via llvm-commits]

Gerolf added a comment.

Could you separate size one checks are OK vs. checks that require even powers of 2? That smells like an inconsistency worth calling out explicitly.

Thanks
Gerolf



================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:7553
 
+  if (NumElts > 1 && NumElts % 2 != 0)
+    return false;
----------------
This check could be the early exit at the start of the function.
