================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:23177-23178
 
+  if (Subtarget->hasSVE2p1() && isREVMask(ShuffleMask, VT, 128) &&
+      VT.getScalarSizeInBits() == 64) {
+    if (!VT.isFloatingPoint())
----------------
Perhaps worth putting `VT.getScalarSizeInBits() == 64` before the called to `isREVMask` so we bail out earlier.
