[Bug target/25765] New: gfortran.dg/assign_2.f90 -O0 fails

[pinskia at gcc dot gnu dot org]

gfortran.dg/assign_2.f90 at -O0 fails because the subtraction between labels in
different sections cannot be done, well it is really the last label is not in
the same section when it should be as there is no nop after the last label.

we get something like:
"L00000000001$pb":
L6:
        popl    %ebx
        leal    _j.0.799-"L00000000001$pb"(%ebx), %eax
        movl    $-1, (%eax)
        leal    _j.1.800-"L00000000001$pb"(%ebx), %edx
        leal    L2-"L00000000001$pb"(%ebx), %eax
....

        leave
        ret
L2:  // <--- there should be a nop here.
        .data
        .align 2
_j.0.799:

A patch like the rs6000 one:
http://gcc.gnu.org/ml/gcc-patches/2003-07/msg02517.html

Should work.

The rs6000 patch (attached) does appear to work, at least on assign_2.f90. 
I'll do a full bootstrap and regression-test, then submit the fix.

4.1 does not support that much of x86-darwin anyways.  So closing as fixed.
