1c06515d92 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.

This is a revised version of

a97cf1fae5 This patch prepares for ELFv2, where sizes of these areas change. It 
also makes some minor changes to improve code efficiency.

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..

77f823e31f stop trying to assing vfp regs once we are done with the registers 2013-11-13 14:26:57 +01:00
David Schneider
37067ec503 mark all vfp registers as used when done. 
To avoid assigning registers the would fit, once arguments have been on
the stack, we mark all registers as used once we do not find a free
register for the first time.
