ADD

Operation

Adds the source operand to the destination operand.

Repeat eligibility

REP eligible; REPcc observes dst

ADD reads the source and destination operands at the selected integer width, adds their values modulo that width, and writes the low result bits to the destination. The common integer result-extension rule defines the upper bits of an Rn destination. The operation leaves FLAGS unchanged.
