Neonint32_tvminvq_s32(int32x4_t a)Vector arithmetic / Across vector arithmetic / Minimum across vector
Description
Signed Minimum across Vector. This instruction compares all the vector elements in the source SIMD&FP register, and writes the smallest of the values as a scalar to the destination SIMD&FP register. All the values in this instruction are signed integer values.
