Alan Modra	164283f4ac	The powerpc64 support opted to pass floating point values both in the ... fpr area and the parameter save area, necessary when the backend doesn't know if a function argument corresponds to the ellipsis arguments of a variadic function. This patch adds powerpc support for variadic functions, and changes the code to only pass fp in the ABI mandated area. ELFv2 needs this change since the parameter save area may not exist there. This also fixes two faulty tests that used a non-variadic function cast to call a variadic function, and spuriously reasoned that this is somehow necessary for static functions..	2013-11-16 06:38:55 -05:00
Alan Modra	58c2577a3f	This enshrines the current testsuite practice of using ffi_arg for ... returned values. It would be reasonable and logical to use the actual return argument type as passed to ffi_prep_cif, but this would mean changing a large number of tests that use ffi_arg and all backends that write results to an ffi_arg.	2013-11-13 16:55:36 -05:00
