I assume this needs a full rebuild of the world ? Might be worth pointing that out in 'Scope' - mclasen
- Added.
this will break the XO the geode CPU is i586 + cmov extention. rpm correctly refuses to install i686 rpms onto the system. currently the os shipped by OLPC has i686 glibc and openssl rpms installed but you can not update them. they only get on because the host that builds images is capable of installing them. - ausil (dgilmore)
- cjb says that i686 should work on the XO
If you are dropping support for i586 CPUs, why is the default -march for 32-bit i586 instead of i686?
- So people can build code for lower CPUs if they require... i686 rpms will be built by explicitly passing -march=i686
