Add Quadword with Overflow (addqv)

Syntax

addqv $s_reg1, $s_reg2, $d_reg

addqv $d_reg/$s_reg1, $s_reg2

addqv $s_reg1, val_immed, $d_reg

addqv $d_reg/$s_reg1, val_immed

Description

Add Quadword (with overflow) computes the sum of two signed 64-bit values. This instruction adds the contents of $s_reg1 to the contents of $s_reg2 or the immediate value and then puts the result in the destination register. If the result cannot be represented as a signed 64-bit number, an integer overflow exception is signaled.
