I have no idea, so just assumed gcc does whatever it does when no -march is supplied, which i guess is just generic x86-64 stuff.
I figured that just -march=amdfam10 was a good start, since it implies MMX, SSE, SSE2, SSE3, SSE4A, 3DNow!, enhanced 3DNow! and ABM, but i may add the rest of my make.conf CFLAGs since I dont have any issues with any other software on this system. Is that fair reasoning?
