Rafael Espindola 6f1b2852fc Produce .weak_def_can_be_hidden for some linkonce_odr values ... With this patch llvm produces a weak_def_can_be_hidden for linkonce_odr if they are also unnamed_addr or don't have their address taken. There is not a lot of documentation about .weak_def_can_be_hidden, but from the old discussion about linkonce_odr_auto_hide and the name of the directive this looks correct: these symbols can be hidden. Testing this with the ld64 in Xcode 5 linking clang reduces the number of exported symbols from 21053 to 19049. llvm-svn: 193718		2013-10-30 22:08:11 +00:00
