[julia-users] cflags

[Samuele Carcagno]

Hi,

when compiling Julia from master, does specifying cflags help get better 
performance for Julia and dependencies, or these are already set at the 
maximum safe optimization levels (or it doesn't matter for other reasons)?

For example for an Ivy Bridge Xeon I was thinking of setting the following:

    export CFLAGS="-march=corei7-avx -O2 -pipe"
    export CXXFLAGS="${CFLAGS}"

btw I'm already setting `OPENBLAS_TARGET_ARCH=SANDYBRIDGE` in 
`Make.user` to optimize openblas.

Cheers,

Sam
