> Hi t.p.northover,
> Hi Tim,
> This patch is to fix a pattern match failure when handling IR like,
> %tmp2 = fptosi <4 x double> %tmp1 to <4 x i16>
> Failure reason is, ReconstructShuffle() wrongly created a CONCAT_VECTOR
> trying to concat 2 of v2i32 into v4i16. This patch can fix this issue and
> try to generate UZP1 instead of lots of MOV and INS. Please review.
