Peter Collingbourne 6bf7e6c622 ThinLTO: Correctly follow aliasee references when dead stripping. ... We were previously handling aliases during dead stripping by adding the aliased global's "original name" GUID to the worklist. This will lead to incorrect behaviour if the global has local linkage because the original name GUID will not correspond to the global's GUID in the summary. Because an alias is just another name for the global that it references, there is no need to mark the referenced global as used, or to follow references from any other copies of the global. So all we need to do is to follow references from the aliasee's summary instead of the alias. Differential Revision: https://reviews.llvm.org/D37789 llvm-svn: 313157		2017-09-13 17:09:20 +00:00
