Vector Add
Purpose:
Floating-point Add (vector). This instruction adds corresponding vector elements in the two source SIMD&FP registers, writes the result into a vector, and writes the vector to the destination SIMD&FP register. All the values in this instruction are floating-point values.
Result:
float64x1_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float64_t a_data[1] = {
3.5
};
float64_t b_data[1] = {
2.5
};
float64x1_t a = vld1_f64(a_data);
float64x1_t b = vld1_f64(b_data);
float64x1_t r = vadd_f64(a, b);
float64_t result[1];
vst1_f64(result, r);
printf("%f\n", result[0]);

Assembly Instruction:
FADD
Usage:
float64x1_t result =
vadd_f64(
float64x1_t a, float64x1_t b
)
