[LLVMdev] [llvmlinux] [LLVMLinux] Regression since r209049/r209065

[Renato Golin]

Could this have unearthed a latent bug?

       for (unsigned J = 0, F = Op1->getNumOperands(); J != F; ++J) {
+        if (Op1->getOperand(J)->getType() != Op2->getOperand(J)->getType())
+          return nullptr;

cheers,
