[PATCH] D27855: try to extend nonnull-ness of arguments from a callsite back to its parent function

[Sanjay Patel via Phabricator via llvm-commits]

spatel retitled this revision from "[InstCombine] try to extend nonnull-ness of arguments from a callsite back to its parent function" to "try to extend nonnull-ness of arguments from a callsite back to its parent function".
spatel updated this revision to Diff 82030.
spatel added a comment.

Patch updated:
Move the logic and test cases from InstCombine to FuncAttrs to avoid sensitivity to function visit ordering, but this exposes a different ordering problem: -functionattrs is currently run after -inline, so this doesn't appear to help the motivating case at all.
