abs | |`x`|
abs-diff | |`x`-`y`| without modulo overflow
add_sat | `x`+`y` and saturate result
hadd | (`x`+`y`) >> 1 without modulo overflow
rhadd | (`x`+`y`+1) >> 1. The intermediate sum does not modulo overflow.
clz | Number of leading 0-bits in `x`
clamp | `min`(`max`( `x`, `minval`), `maxval`)
mad_hi | `mul_hi`(`a`,`b`)+`c`
mad24 | (Fast integer function.) Multiply 24-bit integer then add the 32-bit result to 32-bit integer
mad_sat | `a`*`b`+`c` and saturate the result
max | The greater of `x` or `y`
min | The lessor of `x` or `y`
mul_hi | High half of the product of `x` and `y`
mul24 | (Fast integer function.) Multiply 24-bit integer values `a` and `b`
rotate | result[`indx`]=`v`[`indx`]<<`i`[`indx`]
sub_sat | `x` - `y` and saturate the result
upsample | `result`[i] = ((gentype)`hi`[i] << 8|16|32) | `lo`[i]
popcount | Returns the number of non-zero bits in `x`.
