Assuming we can't just do away with i486 support for now, did anyone track

libgomp assumes 586; there were some GFortran/OMP issues on i386.

Hi,
I just found out that gcc is compiled with --with-arch-32=i586, which
effectively means it builds with -march=i586 by default (and that it
still claims an i486-linux-gnu target).
I'm wondering. Is the project at large aware that we're not building for
i486, but for i586 ? That even the

With -march=i586, code will be generated that runs on a Pentium without

There are a few new instructions on the Pentium that can be used in ring

Well, nobody is running regular kernel regression testing on 486-class
hardware AFAIK, and that
