You are right they should go into LIB2FUNCS_STATIC_EXTRA, I did not know
about that variable, I should have looked more, I had looked a little 
but
only found LIB2ADDEH which was definitely wrong.

Yes they are accepted by all Darwin assemblers from 1.0 (Mac OS X 10.0) 
to
7.2.0 (Mac OS X 10.3.2).  There is only one assembler for Darwin right 
now
a heavy modified gas 1.38.  Also the FSF GCC uses private_extern for 
attribute
hidden and -force_cpusubtype_ALL when you supply -maltivec respectively 
already.

I had forgot about this as I was used to making patches without cvs 
commit
access and that was hard to do a "cvs add".

Ok, here is the patch which I am testing right now.

Thanks,
Andrew Pinski

	* config/rs6000/t-darwin (LIB2FUNCS_STATIC_EXTRA): Add 
darwin-fpsave.asm,
	darwin-vecsave.asm, and darwin-world.asm.
	(TARGET_LIBGCC2_CFLAGS): Add -Wa,-force_cpusubtype_ALL as the asm files
	contain altivec instructions.
	* config/rs6000/darwin-fpsave.asm: New file.
	* config/rs6000/darwin-vecsave.asm: New file.
	* config/rs6000/darwin-world.asm: New file.
