That sounds reasonable. > Or should we go so far as to have configure add -msse2 automatically? Probably not - there's several OSs / distributions that do not yet require an SSE2 capable CPU. While I personally don't care much about such machines, I don't think it's worth desupportem them as long as mainstream compilers with -fexcess-precision=standard exist. Greetings, Andres Freund
