            Bug ID: 63997
           Summary: gcc.dg/lto/pr61526 failing on darwin
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fxcoudert at gcc dot gnu.org

This testcase fails with the following error:

Undefined symbols for architecture x86_64:
  "_master", referenced from:
      _bar in cccerobh.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status


I don't think it's lto-related: even without the lto flags, the same error
message is issued. In fact, even with the system compiler, the same error is
issued.

--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The testcase uses -shared at link time which is supposed to build a shared
object and generate an external (unresolved) reference to _master.  Why is
that (/* { dg-extra-ld-options { -shared } } */) not working on darwin?

Adding -Wl,-undefined,dynamic_lookup makes it pass. (And the -shared is
correctly passed, as far as I can see.)

Does this testcase still fail?
