Delete the setModule method from the Linker.

It was only used from LTO for a debug feature, and LTO can just create
another linker.

It is pretty odd to have a method to reset the module in the middle of a
link. It would make IdentifiedStructTypes inconsistent with the Module

Rafael Espindola [Tue, 1 Dec 2015 17:17:04 +0000 (17:17 +0000)]
Make appending var linking less of a special case.

It has to be a bit special because:
* materializeInitFor is not really supposed to call replaceAllUsesWith.
  The caller has a plain variable with Dst and expects just the
  initializer to be set, not for it to be removed.
* Calling mutateType as we used to do before gets some type
  inconsistency which breaks the bitcode writer.
* If linkAppendingVarProto create a dest decl with the correct type to
  avoid the above problems, it needs to put the original dst init in
  some side table for materializeInitFor to use.

In the end the simplest solution seems to be to just have
linkAppendingVarProto do all the work and set ValueMap[SrcGV to avoid

Bring r254336 back:

The difference is that now we don't error on out-of-comdat access to
internal global values. We copy them instead. This seems to match the
expectation of COFF linkers (see pr25686).

Original message:

    Start deciding earlier what to link.

    A traditional linker is roughly split in symbol resolution and

    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.
