           CE->getOpcode() == Instruction::PtrToInt)
-        if (Q.DL.getTypeSizeInBits(CE->getOperand(0)->getType()) <=
-            Q.DL.getTypeSizeInBits(CE->getType()))
+        if (Q.DL.getTypeSizeInBits(CE->getOperand(0)->getType())
+                .getFixedSize() <=
----------------
In general I think IntToPtr instructions could take scalable vectors as operands, at least looking at InstCombinerImpl::visitIntToPtr suggests that. This is probably ok for now because we bail out for scalable vectors at the top of the function.
