iadd (sm4 - asm)
|iadd dest[.mask], [-]src0[.swizzle], [-]src1[.swizzle]|
[in] The address of the result of the operation.
[in] The number to be added to src1.
[in] The number to be added to src0.
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:
|Vertex Shader||Geometry Shader||Pixel Shader|
