Integer addition.
iadd dest[.mask], [-]src0[.swizzle], [-]src1[.swizzle] |

Item | Description |
---|---|
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.
