[PATCH] D66762: DAG: computeNumSignBits for MUL

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added a comment.

Not sure if we need it for this patch, but I remember that last time I did something with computeNumSignBits in SelectionDAG I was informed that it is possible to add unittests in llvm/unittests/CodeGen/AArch64SelectionDAGTest.cpp. In case you for example want to make more detailed tests.
