* [ThinLTO] Internalize readonly globalsEugene Leviant2018-11-161-1/+1
| | | | | | | | An attempt to recommit r346584 after failure on OSX build bot. Fixed cache key computation in ThinLTOCodeGenerator and added test case llvm-svn: 347033

* [ThinLTO] Internalize readonly globalsEugene Leviant2018-11-101-1/+1
| | | | | | | | | 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
* [ThinLTO] Add FunctionAttrs to ThinLTO indexCharles Saternos2017-08-041-1/+1
| | | | | | Adds function attributes to index: ReadNone, ReadOnly, NoRecurse, NoAlias. This attributes will be used for future ThinLTO optimizations that will propagate function attributes across modules. llvm-svn: 310061
* [ThinLTO] Record calls to aliasesTeresa Johnson2016-10-081-0/+28
Summary: When there is a call to an alias in the same module, we were not adding a call edge. So we could incorrectly think that the alias was dead if it was inlined in that function, despite having a reference imported elsewhere. This resulted in unsats at link time. Add a call edge when the call is to an alias. Reviewers: davide, mehdi_amini Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D25384 llvm-svn: 283664
