Is there a way to get gcc to output the available -march=arch options? I'm getting build errors (tried -march=x86_64) and I don't know what my options are.
The compiler I'm using is a proprietary wrapper around gcc that doesn't seem to like -march=skylake. The flags should be the same so I assume whatever options I'd send to gcc to dump architectures would be the same for this wrapper.
I managed to cause gcc to error with a bogus parameter and it dumped a list, but I'm not seeing that now that I'm going through a wrapper.
How can I get gcc to tell me what it supports?
