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 learn the history, it's all in the mail
git clone git://fedorapeople.org/~djdelorie/bootstrap.git
Since I am still very "arm noob" :-) and just yesterday did
the thumb build to learn about thumb, so far, my impression
is that the best approach should be to use thumb+softfp.
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
I am kind of trying to figure what "The Industry" says
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.
