To me, a sign extension from i32 to i16 makes no sense. >From the .td file, it looks as if src and dest types have been swapped: class XSHWVecInst<ValueType in_vectype, ValueType out_vectype>: XSHWInst<(outs VECREG:$rDest), (ins VECREG:$rSrc), [(set (out_vectype VECREG:$rDest), (sext (in_vectype VECREG:$rSrc)))]>; multiclass ExtendHalfwordWord { def v4i32: XSHWVecInst<v4i32, v8i16>; The multiclass name leads me to believe this was...

Looks like a bug to me. xshw (extend signed half-word(16bits) to word(32bits)) takes a v8i16 and produces a v4i32. This has likely gone unnoticed as there is only one type of...
