mad24(3) Fast integer function to multiply 24-bit integers and add a 32-bit value.

gentype mad24(gentype x, gentype y, gentype z);



multiplies two 24-bit integer values x and y and adds the 32-bit integer result to the 32-bit integer z. See mul24(3clc) to see how the 24-bit integer multiplication is performed.


Fast integer functions can be used for optimizing performance of kernels. We use the generic type name gentype to indicate that the function can take int, int2, int3, int4, int8, int16, uint, uint2, uint4, uint8, or uint16 as the type for the arguments.
