> What I am trying to understand now is about choice of float abi. Not much to understand - each project chooses the abi that best meets their goals.

If you want to do that, you don't need my bootstrap scripts. The whole *point* of a bootstrap was to bring up an *incompatible* abi from scratch. If you want to use a compatible abi, just keep using the armv5 version of Fedora instead. It was decided long ago that the armv7 version of Fedora would use the hardfp abi (hence the project name "hardfp bootstrap"), but you can't build hardfp binaries on a softfp platform, so we had to start from scratch to do hardfp. It's also a fun exercise in bootstrapping, to make sure we still can do it. > I am kind of trying to figure what "The Industry" says about it, If you need someone else's approval, you've missed the point of Free Software. Each project has their own goals, and there is no "The Industry" to tell us what to do. If you want to be part of a project, find the one that has the same goals as you do, and join them. > If I understand correctly, neon will have better support for > simd instructions right? There are still some armv7 chips that don't have neon, though, so we (Fedora) chose to avoid neon for now. _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
