Operation

Writes the signed greater of source and destination to the destination.

Assembler Syntax

MAXS.{B|W|L|Q}(z) <ea>(e), Rn(d)

Repeat eligibility

REP eligible; REPcc observes dst

Compares the selected-width operands as signed integers and writes the greater value to the destination. A sub-Q Rn result is sign-extended to 64 bits.
