This separates the 32-bit sysv/linux/bsd code from the 64-bit linux
code, and makes it possible to link code compiled with different
options to those used to compile libffi. For example, a
-mlong-double-128 libffi can be used with -mlong-double-64 code.
Using the return value area as a place to pass parameters wasn't such
a good idea, causing a failure of cls_ulonglong.c. I didn't see this
when running the mainline gcc libffi testsuite because that version of
the test is inferior to the upstreamm libffi test.
Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant
that a parameter save area could be allocated before it was strictly
necessary. Wrong but harmless. Found when splitting apart ffi.c
into 32-bit and 64-bit support.

The powerpc64 ABIs align structs passed by value, a fact ignored by
gcc for quite some time. Since gcc now does the correct alignment,
libffi needs to follow suit. This ought to be made selectable via
a new abi value, and the #ifdefs removed from ffi.c along with many
other #ifdefs present there and in assembly. I'll do that with a
followup patch sometime.

Alan Modra [Sat, 16 Nov 2013 11:38:55 +0000 (06:38 -0500)]
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..

This enshrines the current testsuite practice of using ffi_arg for

return argument type as passed to ffi_prep_cif, but this would mean
