[PATCH] D100095: [InstCombine] Conditionally emitting nsw/nuw flags when combining two add operations

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

These transforms appear to be untested, so I pushed the tests here:
6fccfd7cbdca <https://reviews.llvm.org/rG6fccfd7cbdca0c1184cdb77f92329534ffde544c>

So now you can rebase, run llvm/utils/update_test_checks.py on that file, and we'll see the diffs.
It would also be good to use Alive2 to confirm that the current results are buggy and the updated results are as expected. For example:
