iadd (sm4 - asm)

Integer addition.

iadd dest[.mask], [-]src0[.swizzle], [-]src1[.swizzle]

 

ItemDescription

dest

[in] The address of the result of the operation.

src0

[in] The number to be added to src1.

src1

[in] The number to be added to src0.

 

Remarks

Component-wise add of 32-bit operands src0 and src1, placing the correct 32-bit result in dest. No carry or borrow beyond the 32-bit values of each component is performed, so this instruction is not sensitive to the signed-ness of its operands.

Optional negate modifier on source operands takes 2's complement before performing operation.

This instruction applies to the following shader stages:
