[PATCH] D132555: [instcombine] Optimise for zero initialisation of integer product

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

Note that "-ipsccp" already simplifies this example:

So I'm not sure if there's any practical benefit. It makes instcombine more uniform, so I don't object. We might also go in the other direction, but I don't know what it would take to make sccp FP-aware.
