I only have MIPSPro documentation, but I wasn't aware of GCC's -march options for MIPS since I've barely used GCC by comparison. The mipspro flags are documented in places like: http://fy.chalmers.se/UNICC/perf_tuning/...roc=r10000

I also have some info on the mipspro wiki article: https://wiki.irixnet.org/MIPSPro

Considering how esoteric GCC documentation is by comparison. I'd have to really have someone whose more familiar with GCC and can actually sit and find all of the flag equivalents that MIPSPro has to GCC, then maybe more scientific tests can be performed regarding codegen for the two. But I don't really have the motivation to sit and dig through a compiler's documentation that much for something I'm not that passionate about. We have a long history of showing that MIPSPro can in many circumstances produce better results. I think that anything beyond that is semantical.
