/* Does the specified function use the "struct returning" convention
or the "value returning" convention? The "value returning" convention
almost invariably returns the entire value in registers. The
"struct returning" convention often returns the entire value in
memory, and passes a pointer (out of or into the function) saying
where the value (is or should go).
Since this sometimes depends on whether it was compiled with GCC,
this is also an argument. This is used in call_function to build a
stack, and in value_being_returned to print return values.
On sparc64, all structs are returned via a pointer. */
