[PATCH] D49362: [ThinLTO] Internalize read only globals

[Eugene Leviant via Phabricator via llvm-commits]

evgeny777 updated this revision to Diff 170611.
evgeny777 added a comment.

- ReadOnly attribute's been moved to `GlobalVarSummary` and is calculated on analysis phase
- Added flag to `ValueInfo` which indicates "constantness" instead of using constant reference counter in `FunctionSummary`
- Fixed few issues including GV to GV references
- Fixed bitcode tests and added extra test cases
