speculable  exu stream  exu block  compute phase   operation   in the signed integer value domain   using widening overflow behavior   that produces condition codes

native on: all

Widening signed integer vector subtraction. If any of the result values in the vector overflows, the vector is widened as with widenuv.

subswv(s x, s y) → s r0, s r1

operands: like Widenv XX:2X2X
