Evgeniy Stepanov a340589458 [asan] Fix dead stripping of globals on Linux. ... Use a combination of !associated, comdat, @llvm.compiler.used and custom sections to allow dead stripping of globals and their asan metadata. Sometimes. Currently this works on LLD, which supports SHF_LINK_ORDER with sh_link pointing to the associated section. This also works on BFD, which seems to treat comdats as all-or-nothing with respect to linker GC. There is a weird quirk where the "first" global in each link is never GC-ed because of the section symbols. At this moment it does not work on Gold (as in the globals are never stripped). This is a re-land of r298158 rebased on D31358. This time, asan.module_ctor is put in a comdat as well to avoid quadratic behavior in Gold. llvm-svn: 299697		2017-04-06 19:55:17 +00:00
