Обсуждение: pgsql: Use native CRC instructions on 64-bit LoongArch
Use native CRC instructions on 64-bit LoongArch As with the Intel and Arm CRC instructions, compiler intrinsics for them must be supported by the compiler. In contrast, no runtime check is needed. Aligned memory access is faster, so use the Arm coding as a model.
