--- Comment #12 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
In libgfortran, we have
#define GFC_ARRAY_DESCRIPTOR(type) \
struct {\
type *base_addr;\
size_t offset;\
dtype_type dtype;\
index_type span;\
descriptor_dimension dim[];\
}
and then later
typedef GFC_ARRAY_DESCRIPTOR (GFC_INTEGER_4) gfc_array_i4;
so the array descriptors expected by the libgfotran routines
have a flexible array members.
If, in the front end, we have the equivalent of (the type name
isn't exactly what the front end generates)
typedef struct {
GFC_INTEGER_4 *base_addr;\
size_t offset;\
dtype_type dtype;\
index_type span;\
descriptor_dimension dim[3];\
} _array03_integer_4_descriptor;
_array03_integer_4_descriptor my_descriptor;
and a pointer type that corresponds to what the library
expects, we should then be able to call
minloc_... ((gfc_array_i4 *) &my_descriptor, ..)
right?
I think this should probably be restricted to calling the
library, I would feel nervous touching use code with this.
