Neonint8x8_tvabs_s8(int8x8_t a)Vector arithmetic / Absolute / Absolute value
Description
Absolute value (vector). This instruction calculates the absolute value of each vector element in the source SIMD&FP register, puts the result into a vector, and writes the vector to the destination SIMD&FP register.
