Tom Lane c3dc311ffd pg_attribute_no_sanitize_alignment() macro ... Modern gcc and clang compilers offer alignment sanitizers, which help to detect pointer misalignment. However, our codebase already contains x86-specific crc32 computation code, which uses unalignment access. Thankfully, those compilers also support the attribute, which disables alignment sanitizers at the function level. This commit adds pg_attribute_no_sanitize_alignment(), which wraps this attribute, and applies it to pg_comp_crc32c_sse42() function. Back-patch of commits 993bdb9f9 and ad2ad698a, to enable doing alignment testing in all supported branches.
