[PATCH] D108699: [LAA] Analyze pointers forked by a select

[Graham Hunter via Phabricator via llvm-commits]

huntergr updated this revision to Diff 388889.
huntergr added a comment.

Rebased, disabled by default, added a couple of different instructions into the tests to ensure those paths are at least covered even if they aren't in a positive case right now; I'm still planning to leave those cases (known strides, g/s, uniform) for a followup patch; I suppose I could start a patch series if people want to see those earlier.

I've run the LNT nightly suite with this enabled, along with a few HPC benchmarks I have access to and they all pass.
