Bruno Cardoso Lopes	d23709b18c	Add v8i32 and v4i64 vpermil patterns ... llvm-svn: 136451	2011-07-29 01:31:07 +00:00
Bruno Cardoso Lopes	27a30a7792	The vpermilps and vpermilpd have different behaviour regarding the ... usage of the shuffle bitmask. Both work in 128-bit lanes without crossing, but in the former the mask of the high part is the same used by the low part while in the later both lanes have independent masks. Handle this properly and and add support for vpermilpd. llvm-svn: 136200	2011-07-27 00:56:34 +00:00
