Purpose:
Compute the square root of packed half-precision (16-bit) floating-point elements in "a", and store the results in "dst".
Result:
__m128h
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m128h a = _mm_setr_ph(1.0, 4.0, 9.0, 16.0, 25.0, 36.0, 49.0, 64.0);
__m128h result = _mm_sqrt_ph(a);
_Float16* res = (_Float16*)&result;
for (int i = 0; i < 8; i++)
printf("%f\n", (float)res[i]);
