CAS being a compare and swap? Which is the atomic function they want to use? > To me that sounds reasonable enough as to why we should be building > 0ad with -march=i686. Anyway, I have no idea if g++ supports those new atomic functions without -march=i686, but I at least hope so. > >> > It wasn't using -march=athlon64 on amd64 before either as far as I > >> > know but had problem running on at least one of the buildds. > >> > >> The original issue was that nvidia-texture-tools was compiled with > >> -march=athlon64, which caused one of the amd64 buildds to complain > >> about an "Illegal instruction" when trying to run 0ad's test suite > >> when building 0ad.

I've triggerd that it gets build on barber, you should have a log about that in half an hour I guess.
