vcgtq_s64ADD TO COMPARE ADDED TO COMPARE
Arm 64-bit (64 bits)/ NEON
View official documentation
Purpose:
Compare signed Greater than (vector). This instruction compares each vector element in the first source SIMD&FP register with the corresponding vector element in the second source SIMD&FP register and if the first signed integer value is greater than the second signed integer value sets every bit of the corresponding vector element in the destination SIMD&FP register to one, otherwise sets every bit of the corresponding vector element in the destination SIMD&FP register to zero.
Result:
uint64x2_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
int64x2_t a = vdupq_n_s64(5);
int64x2_t b = vdupq_n_s64(3);
uint64x2_t result = vcgtq_s64(a, b);
uint64_t *res = (uint64_t*)&result;
for(int i = 0; i < 2; i++)
printf("%llu ", res[i]);
return 0;
