/* This group of functions allows a caller to evaluate an expression from
|
|
the callee's interface. It establishes a mapping between the interface's
|
|
dummy arguments and the caller's actual arguments, then applies that
|
|
mapping to a given gfc_expr.
|
|
|
|
You can initialize a mapping structure like so:
|
|
|
|
gfc_interface_mapping mapping;
|
|
...
|
|
gfc_init_interface_mapping (&mapping);
|
|
|
|
You should then evaluate each actual argument into a temporary
|
|
gfc_se structure, here called "se", and map the result to the
|
|
dummy argument's symbol, here called "sym":
|
|
|
|
gfc_add_interface_mapping (&mapping, sym, &se);
|
|
|
|
After adding all mappings, you should call:
|
|
|
|
gfc_finish_interface_mapping (&mapping, pre, post);
|
|
|
|
where "pre" and "post" are statement blocks for initialization
|
|
and finalization code respectively. You can then evaluate an
|
|
interface expression "expr" as follows:
|
|
|
|
gfc_apply_interface_mapping (&mapping, se, expr);
|
|
|
|
Once you've evaluated all expressions, you should free
|
|
the mapping structure with:
|
|
|
|
gfc_free_interface_mapping (&mapping); */
