I am trying to do a bitwise &
between elements of two arrays of uint64_t
integers and then store the result in another array. This is my program:
#include <emmintrin.h>
#include <nmmintrin.h>
#include <chrono>
int main()
{
uint64_t data[200];
uint64_t data2[200];
uint64_t data3[200];
__m128i* ptr = (__m128i*) data;
__m128i* ptr2 = (__m128i*) data2;
uint64_t* ptr3 = data3;
for (int i = 0; i < 200; ++i, ++ptr, ++ptr2, ptr3 += 2)
_mm_store_ps(ptr3, _mm_and_si128(*ptr, *ptr2));
}
However, I get this error:
test.cpp:17:50: error: cannot convert ‘uint64_t* {aka long unsigned int*}’ to ‘float*’ for argument ‘1’ to ‘void _mm_store_ps(float*, __m128)’
_mm_store_ps(ptr3, _mm_and_si128(*ptr, *ptr2));
For some reason, the compiler thinks I'm copying to an array of floats. Is it possible to do what I am trying to do with arrays of uint64_t
?
