I decided to rebuild my Julia installation, and in the process try to optimize the build to my machine. As a first attempt, I just added a file Make.user to the Julia directory, with the single line "MARCH=native" in it. No other changes to the current master.
Is there any way to inspect what options were actually used when building, other than digging around in the build scripts and try to deduce it myself? For example, I have a SandyBridge CPU, but if I understand the docs correctly the default arch is Nehalem. Is there a (simple) way to check that this was taken into account in my build? // Tomas
