Thread: pgsql: Use ARM Advanced SIMD (NEON) intrinsics where available
Use ARM Advanced SIMD (NEON) intrinsics where available NEON support is required on the Aarch64 architecture for standard implementations. Hardware designers for specialized markets can choose not to support it, but that's true of floating point as well, which we assume is supported. As with x86, some SIMD support is available on 32-bit platforms, but those are not interesting from a performance standpoint and would require an inconvenient runtime check.
