Should this be the default on linux and BSDs?
I personally think -march=native is not the right default, but I see the arguments for it. I guess the argument for making it the default on Linux/BSDs is that many users build their own software? What do modern GCC's do? IIRC, you brought this up before and I don't think I was the only opponent. We also need to finish off some of the feature detection before this feature works solidly. - Daniel > -Chris > > _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
