[Discuss-gnuradio] Question on processor micro-architecture and GNU Radio

[Ali Dormiani]

Hello all,

I was wondering how the compiler option "-march=native" effects large FOOS projects like GNU Radio.

There seems to be conflicting opinions online, ranging from "it's does nothing" to "it can break code".

Would GNU Radio (and VOLK by extension) benefit from this compiler option for AVX512 (or other advanced x68-64 ISA) compliant chips?

Thank you for your time,

Ali
