Rafael Espindola bdb4d2f2db Add support for comdats to the gold plugin. ... There are two parts to this. First, the plugin needs to tell gold the comdat by setting comdat_key. What gets things a bit more complicated is that gold only seems symbols. In particular, if A is an alias to B, it only sees the symbols A and B. It can then ask us to keep symbol A but drop symbol B. What we have to do instead is to create an internal version of B and make A an alias to that. At some point some of this logic should be moved to lib/Linker so that we don't map a Constant to an internal version just to have lib/Linker map that again to the destination module. The reason for implementing this in tools/gold for now is simplicity. With it in place it should be possible to update clang to use comdats for constructors and destructors on ELF without breaking the LTO bootstrap. Once that is done I intend to come back and improve the interface lib/Linker exposes. llvm-svn: 216302		2014-08-22 23:26:10 +00:00
