Rafael Espindola a586fd2c56 Start deciding earlier what to link. ... A traditional linker is roughly split in symbol resolution and "copying stuff". The two tasks are badly mixed in lib/Linker. This starts splitting them apart. With this patch there are no direct call to linkGlobalValueBody or linkGlobalValueProto. Everything is linked via WapValue. This also includes a few fixes: * A GV goes undefined if the comdat is dropped (comdat11.ll). * We error if an internal GV goes undefined (comdat13.ll). * We don't link an unused comdat. The first two match the behavior of an ELF linker. The second one is equivalent to running globaldce on the input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@254336 91177308-0d34-0410-b5e6-96231b3b80d8		2015-11-30 22:01:43 +00:00
