IR canonicalization: shufflevector or vector trunc?
Right - I think that case looks like this for little endian:
define <2 x i32> @zextshuffle(<2 x i16> %x) {
%zext_shuffle = shufflevector <2 x i16> %x, <2 x i16> zeroinitializer, <4
x i32> <i32 0, i32 2, i32 1, i32 2>
%bc = bitcast <4 x i16> %zext_shuffle to <2 x i32>
ret <2 x i32> %bc
}
define <2 x i32> @zextvec(<2 x i16>...
