[Aldy Hernandez]

hullo.

here is a patch to add new altivec triplets for native linux ppc +
altivec and eabi + altivec.

ok?

2001-12-12  Aldy Hernandez  <aldyh@redhat.com>

	* rs6000.c (rs6000_override_options): Add
	SUBSUBTARGET_OVERRIDE_OPTIONS.

	* eabialtivec.h: New file.
	
	* linuxaltivec.h: New file.

	* config.gcc: Add powerpc-*-eabialtivec and
	powerpc-*-linux-gnualtivec.
