           Summary: gfrtran DECL issues in function declaration
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org


Split off from 48286. Richard writes there:

Btw, fndecl issue - if you build at least cray_pointers_8.f90 with
-fwhole-program
I get

/tmp/ccBnfOGf.o: In function `main':
cray_pointers_8.f90:(.text.startup+0x76): undefined reference to `euler_'
collect2: ld returned 1 exit status

which means the euler fn has a different decl than the one called from main.


I can reproduce this with:
  gfortran -fcray-pointer -O2 -fwhole-program cray_pointers_8.f90

The reason for the issue can be found in trans-decl.c:

gfc_get_extern_function_decl (gfc_symbol * sym)
[...]
  /* Do not use procedures that have a procedure argument because this
     can result in problems of multiple decls during inlining.  */
  proc_formal_arg = false;
  if (gsym && gsym->ns && gsym->ns->proc_name)

Patch: http://gcc.gnu.org/ml/fortran/2011-04/msg00166.html

The initial code was introduced for PR 45743 but does not seem to be needed any
more.
