The default assembler does not, and Atlas's build process outputs a note to that respect in the beginning of the log file ("disabling AVX" or similar). However, I replaced /opt/local/bin/as with a script that calls a different assembler, so that AVX instructions work fine on my system. Maybe there is a configure check for AVX that unexpectedly succeeds? -- Ticket URL: <https://trac.macports.org/ticket/44533#comment:3> MacPorts <http://www.macports.org/> Ports system for OS X
