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

aliases: addus2
native on: all

Saturating unsigned integer addition. When a result value overflows for the width, it flats out at the biggest value.


addus(u x, u y) → u r0

operands: like Identity [xx:x]

addus(u x, imm y) → u r0

operands: like Identity [xx:x]
