* ThinLTO: Do not import debug info for imported global constantsDavid Blaikie2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | It looks like this isn't necessary (in any tests I've done, it results in the global being described with no location or value in the imported side - while it's still fully described in the place it's imported from) & results in significant/pathological debug info growth to home these location-less global variable descriptions on the import side. This is a rather pressing/important issue to address - this regressed executable size for one example I'm looking at by 15%, object size is probably similar though I haven't measured it, and a 22x increase in the number of CUs in the cu_index in split DWARF DWP files, creating a similarly large regression in the time it takes llvm-symbolizer to run on such binaries.

* [ThinLTO] Add some stats for read only variable internalizationTeresa Johnson2018-11-171-1/+10
| | | | | | | | | | | | | | | Summary: Follow up to D49362 ([ThinLTO] Internalize read only globals). Add a statistic on the number of read only variables (only counting live variables since dead variables will be dropped anyway).

* [ThinLTO] Internalize readonly globalsEugene Leviant2018-11-101-0/+40
This patch allows internalising globals if all accesses to them (from live functions) are from non-volatile load instructions Differential revision: https://reviews.llvm.org/D49362 llvm-svn: 346584
