            Bug ID: 63893
           Summary: gcc.dg/pr61599-1.c fails on darwin, due to
                    -mcmodel=medium
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fxcoudert at gcc dot gnu.org

$ ./bin/gcc pr61599-1.c pr61599-2.c -mcmodel=medium -fdata-sections
Undefined symbols for architecture x86_64:
  "_GLOBAL_OFFSET_TABLE_", referenced from:
      _main in ccHQCqNA.o
      _bar in cckQelee.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status

I get that -mcmodel=medium is not working well for darwin at the moment, but
didn't know whether there is already a bug tracking that in general at the
moment. So I open this one.

gcc.target/i386/pr63538.c also fails, also due to -mcmodel=medium

pr63793 also is -mcmodel=medium bug on darwin which is detected by the linker.

Another sequel of r216154.

Note that tests with -mcmodel=* are compiled on darwin, but produce codes that
are not accepted by as (see also pr50077).
