Andrea Di Biagio 98dd66445e [X86] Improve the lowering of BITCAST from MVT::f64 to MVT::v4i16/MVT::v8i8. ... This patch teaches the x86 backend how to efficiently lower ISD::BITCAST dag nodes from MVT::f64 to MVT::v4i16 (and vice versa), and from MVT::f64 to MVT::v8i8 (and vice versa). This patch extends the logic from revision 208107 to also handle MVT::v4i16 and MVT::v8i8. Also, this patch correctly propagates Undef values when performing the widening of a vector (example: when widening from v2i32 to v4i32, the upper 64bits of the resulting vector are 'undef'). llvm-svn: 209451		2014-05-22 16:21:39 +00:00
