testsuite, fortran: make mixed-lang-stack less compiler dependent
In the gdb.fortran/mixed-lang-stack.exp test when somewhere deep in a
bunch of nested function calls we issue and test a 'info args' command
for the mixed_func_1b function (when in that function's frame).
The signature of the function looks like
subroutine mixed_func_1b(a, b, c, d, e, g)
use type_module
implicit none
integer :: a
real(kind=4) :: b
real(kind=8) :: c
complex(kind=4) :: d
character(len=*) :: e
character(len=:), allocatable :: f
TYPE(MyType) :: g
and usually one would expect arguments a, b, c, d, e, and g to be
emitted here. However, due to some compiler dependent treatment of the
e array the actual output in the test (with gfortran/ifx) is
(gdb) info args
a = 1
b = 2
c = 3
d = (4,5)
e = 'abcdef'
g = ( a = 1.5, b = 2.5 )
_e = 6
where the compiler generated '_e' is emitted as the length of e. While
ifort also generates an additional length argument, the naming (which is
up to the compilers here I think, I could not find anything in the
Fortran standard about this) is different and we see
(gdb) info args
a = 1
b = 2
c = 3
d = (4,5)
e = 'abcdef'
g = ( a = 1.5, b = 2.5 )
.tmp.E.len_V$4a = 6
To make both outputs pass the test, I kept the additional argument for now and
made the regex for the emitted name of the last variable match any
arbitrary name.
