target-ppc: Altivec 2.07: Doubleword Compares
This patch adds the Vector Compare Doubleword instructions introduced by Power ISA Version 2.07: - Vector Compare Equal to Unsigned Doubleword (vcmpequd) - Vector Compare Greater Than Signed Doubleword (vcmpgtsd) - Vector Compare Greater Than Unsigned Doubleword (vcmpgtud) These instructions are encoded with bit 31 set to 1 and so are duals with vcmpeqfp, vcmpgtfp and vcmpbfp respectively. The helper macro for integer compares is enhanced to account for 64-bit operands. Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
