[Bug fortran/32600] [ISO Bind C] C_LOC/C_FUNLOC should not be library functions

[burnus at gcc dot gnu dot org]

Analogously for c_f_pointer (without SHAPE) and c_f_funpointer:

use iso_c_binding
implicit none
integer, target :: tgt
type(c_ptr) :: cptr
integer, pointer :: ptr
 cptr = c_loc(tgt)
 call c_f_pointer(cptr,ptr)
end


gfortran:
  c_f_pointer_i4 (cptr, &ptr, 0B);
g95:
  ptr = cptr;;
NAG f95:
  ptr_ = cptr_;


For shape, one can also consider generate the code directly.
gfortran and g95 call a library function but NAG f95 generates the C code
directly:

use iso_c_binding
implicit none
integer, target :: tgt(10)
type(c_ptr) :: cptr
integer, pointer :: ptr(:)
 cptr = c_loc(tgt)
 call c_f_pointer(cptr,ptr, (/ 10 /))
end
