This tests OK on my Debian buster aarch64 system (the machine that runs "eelpout" in the buildfarm), configure tests as expected and I confirmed that pg_comp_crc32c_armv8 is reached at runtime. I hope we can figure out a more portable way to detect the instructions, or failing that a way to detect them on FreeBSD in userspace. I'll try to send a patch for PG12 if I get a chance. No opinion on the unaligned memory access question. -- Thomas Munro http://www.enterprisedb.com
