[PATCH] D45378: [InstCombine] Propagate null values from conditions to other basic blocks

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Note that such a transform (`null` propagation) is already being done somewhere. https://godbolt.org/g/ow79c8
I'd recommend to first look where that is happening, and extend that, not introduce a duplicate-but-better fold elsewhere.
