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

native on: all

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


subuwv(u x, u y) → u r0, u r1

operands: like Widenv XX:2X2X
