Toolchain rework, call for testing

Toolchain rework, call for testing

[Khem Raj]

Hi All

Recently glibc build has been simplified upstream. It has dropped the
dependency on libgcc_s and libgcc_eh for building glibc itself.
This means that we can simplify our toolchain bootstrap a bit by
dropping 1 of the 3 cross gcc build stages. We do not need
gcc-cross-intermediate
anymore. This should bring some build time reduction and simplify the
bootstrap. I have a series of patches which I have tested
by building core-image-minimal and meta-toolchain for all supported
qemu architectures and also uclibc/eglibc both
but it needs a lot more testing therefore I am calling out wider
audience for help in testing it out.

The branch is

http://git.openembedded.org/openembedded-core-contrib/log/?h=kraj/toolchain-rework

Thanks

Hi Khem,

I successfully built core-image-minimal for qemuarm and tested it in 
qemu with a completely fresh clone.

hmm, Add libgcc to DEPENDS of gmp-4.2.1 and see if that fixes this issue

Please adapt also toolchain-layer in meta-oe for those stuck with gcc 4.6.

Why is it that gcc-4.7 doesn't work for those people?

At least it should parse for people who have toolchain-layer enabled..

Maybe it's because 
http://git.openembedded.org/openembedded-core/commit/?id=30617bde61a3b0a0944b49a0c9fb7159dacbb19f
is missing PR bump and gcc wasn't rebuilt before eglibc upgrade (OEBasic not OEBasicHash here).

I have troubles with older versions of the Linux kernel on ARM.  Anything
older than 3.2 either doesn't boot or is unstable.  Kernel only, user code
built with 4.7+ seems to be fine.  Since I need to use those older kernels
and I don't have the time/budget to figure out why they don't work with 4.7+,
I'm sticking with 4.6+ for now.

Yes. I am testing a patch for it. For tries just delete the *intermediate* files
and see if it helps, I believe you will need it for meta-linaro as well.

yes seems so. I have stopped using OEBasic long ago, you should stop
using it too.
But feel free to send a PR bump patchlet.

I'm using OEBasicHash on one jenkins setup, but that one is still
building changes from 2 days ago.. (building 24/7.. )
