+/* 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 i960, a structure is returned in registers g0-g3, if it will fit.
+   If it's more than 16 bytes long, g13 pointed to it on entry.  */
