Subject: [Buildroot] [PATCH 2/7] toolchain-external: CodeSourcery PowerPC: support only one version

Romain, All,
On 2015-12-19 19:14 +0100, Romain Naour spake thusly:

So, this means that the only CS PPC toolchain we're left with requires a
PPC with SPE, which is basically only two variants, 8540 (e500v1) and
8548 (e500v2) in Buildroot. All other PPC CPU can't use that toolchain.
Which makes for some fun-to-debug autobuild failures such as:
http://autobuild.buildroot.org/results/092/09245cb36fe507346b1810262f331c0242b5325d/
What's fun in there is:
- that config uses a musl toolchain,
- the target optimisations are set to '-te500v2' which break the build,
- we have -te500v2 nowhere in the Buildroot code,
- the only -te500v2 is in a toolchain config in the autobuilders code,
- that toolchain config uses a CS toolchain, but the autobuild failure
is using the musl toolchain.
So, it got me puzzled for quite a while there... Until I realised we had
a few issues:
- the autobuilder config used as a base does not enforce a ppc8548,
- that same config was not updated after the removal of CS toolchains,
- other autobuilder base configs were not updated either.
However, do we really want to keep the single CS PPC toolchain with a
dependency on SPE? Can't we just do like the Linaro toolchain and use
the appropriate toolchain depending on the rest of the configuration?
I will try to get my hands on this during the WE, but I make no promise.
It would be good if you could have a look, too. ;-)
Regards,
Yann E. MORIN.
