[Buildroot] [PATCH 0/6] Various external toolchain updates

[Thomas Petazzoni]

Hello,

Here is a round of misc external toolchain updates: Sourcery ARM,
Sourcery MIPS, Linaro ARM, Linaro AArch64, Blackfin, and deprecation
of Microblaze toolchains.

Thomas

Thomas Petazzoni (6):
  toolchain-external: add Sourcery ARM 2013.11, remove Sourcery ARM
    2011.09
  toolchain-external: add Sourcery MIPS 2013.11, remove Sourcery MIPS
    2012.03
  toolchain-external: update Linaro ARM toolchains
  toolchain-external: update Linaro AArch64 toolchains
  toolchain-external: mark Microblaze external toolchains as deprecated
  toolchain-external: add support for the Blackfin 2013R1 toolchain

[Buildroot] [PATCH 1/6] toolchain-external: add Sourcery ARM 2013.11, remove Sourcery ARM 2011.09

[Thomas Petazzoni]

This commit adds the support for the recently release Sourcery ARM
2013.11 toolchain (gcc 4.8, gdb 7.6, glibc 2.18, gdb 7.6), and
consequently removes the support for the Sourcery ARM 2011.09
toolchain.

[Buildroot] [PATCH 3/6] toolchain-external: update Linaro ARM toolchains

[Thomas Petazzoni]

Add Linaro ARM 2013.10 and Linaro ARM 2013.11, and remove Linaro ARM
2013.07 and Linaro ARM 2013.08.

The main change for those versions is the switch to eglibc 2.18.

[Buildroot] [PATCH 5/6] toolchain-external: mark Microblaze external toolchains as deprecated

[Thomas Petazzoni]

The Xilinx Microblaze external toolchains that we had support for are
very old, and are causing a huge number of build issues. Thanks to
Spenser Gilliland, we now have support for Microblaze in the internal
toolchain backend, and the autobuilders have been using the internal
toolchain backend since then. Therefore, it's time to deprecate those
old and unusable external toolchains.

You mention gdb twice. The same goes for the previous patch.

Looks like you're fixing help at the same time, too. Maybe jsut add a
small sentence to the commit log:
    Fix help texts about MIPS64 inconsistencies.

I find it odd that the menu are listed with reverse order, most recent
first, while the Makefiles are listed in order, oldest first. This
applies to all toolchains, not only the Linaro ones.

Of course, this is not the fault of this patch, as you kept the previous
order. So it does not bar you from applying it.

Yann E. MORIN.

A while back we discussed the desirability of having so many
subsequent versions of the same toolchain type (in this case Linaro).
IIRC (but I did not cross-check with the actual discussion yet) the
conclusion was that it'd be good to use the gcc version as milestone,
and keep e.g. a 4.4, 4.6, 4.8 gcc based Linaro toolchain, but not keep
multiple 4.8-based versions.

Until now this has not yet been implemented. We could do this in a
one-shot approach, or gradually as new toolchains are added. If we opt
for the second option, your current patchset could be revised to align
with the new strategy.

What do you think about that?

Best regards,
Thomas

I continue to think that it doesn't work, as I already expressed
originally. Using the gcc version as a way of keeping different
generations of toolchain is, in my opinion, broken: in the present
update of the ARM Linaro toolchain, we continue to have only gcc 4.8
based toolchains, but the newer ones are based on eglibc 2.18, while the
previous ones are based on eglibc 2.17. This is a fairly significant
difference, but if we use only the gcc version as the way of
distinguishing generations of toolchain, then we would get rid of gcc
4.8/eglibc 2.17 toolchains today.

Why would we keep a very old gcc 4.7.x toolchain, but immediately get
rid of a more recent gcc 4.8 toolchain that is based on eglibc 2.17 ?

As we never managed to come up with a reasonable model to handle this,
I believe we should in the mean time continue to update the toolchains
as we used to do in the past.

Thanks!

Thomas

While I agree that the existing patchset could continue in the
meanwhile, I think it is worth revisiting the core discussion. For
reference, here is the previous discussion:
http://lists.busybox.net/pipermail/buildroot/2013-October/080119.html

Back then (October) there was not much debate about the idea of only
providing sufficiently-different versions of the Linaro toolchains.
The biggest problem was how to identify the toolchains so that 'minor'
updates can keep the same config symbol (and thus be transparent to
users). This boils down to the question: which parts of the toolchain
may change to continue considering it as 'the same' toolchain.
I think everyone will agree that a new gcc version or a new C library
version means a different toolchain.
However, what about the other parts? If Linaro updates binutils, do we
consider it the same toolchain or not?

Based on this we could devise some logical names of the config symbols.
Note that this does not mean we can't change our minds later. Suppose
we start with the gcc/libc combination as key, and we'd have symbols
LINARO_GCC_4_8_GLIBC_2_17
LINARO_GCC_4_8_GLIBC_2_18
LINARO_GCC_5_0_GLIBC_2_18

and suddenly Linaro releases a toolchain with the same gcc and glibc
version, but some other change that we consider as significant. Then
at that point we can simply introduce a new symbol and keep both, for
example:
LINARO_GCC_4_8_GLIBC_2_17
LINARO_GCC_4_8_GLIBC_2_18
LINARO_GCC_5_0_GLIBC_2_18
LINARO_GCC_5_0_GLIBC_2_18_OTHER_FEATURE


Does this make sense? Did I overlook something?

Thanks,
Thomas

My personal view on this is that I still don't really understand what
is the problem with the current naming scheme. If an user upgrades from
one Buildroot version to another then the version of all components
*are* changing, without changes to the corresponding Config.in symbol.
You update Buildroot, then suddenly you get Qt 5.2 instead of Qt 5.1,
without being notified. At the next Buildroot upgrade, you may still be
using Qt 5.2, or Qt 5.2.1, or Qt 5.3, or 5.4. You have to verify it.

With Linaro toolchains, if you use Linaro 2013.02 in your Buildroot
configuration, then update to a new Buildroot version that still has
Linaro 2013.02, then you will continue to use this toolchain. However,
if Buildroot has updated a number of Linaro toolchains, and 2013.02 is
no longer available, you will automatically default to the latest
Linaro toolchain that exists for your architecture, maybe 2013.06 or
2013.07.

What's the difference with Qt? I don't see any, to be honest.

Best regards,

Thomas

One big difference is that for qt5 you cannot select the version, you
just say "I want qt5".
For the external toolchains, you specify a particular version, out of
a set of provided versions.

The problem arises when we introduce support for a newer version. For
qt5 (and most packages) we simply replace the old version with the new
one. No notification. No migration.
For toolchains (and some other packages) we add the new version, and
typically remove one or more old versions. The question is now: which
toolchains to remove?
- The oldest one? This is the approach taken currently for Linaro toolchains.
- The latest, most similar one?

For Sourcery toolchains, there are versions and patch levels. The
introduction of a toolchain version 2013.11 patchlevel 50 will
overwrite the previous toolchain 2013.11 patchlevel 40 (just an
example). We don't keep two patchlevels of the same toolchain version.
For Linaro, there are no real patchlevels (as far as I understood, I'm
no expert there) but they call everything a new 'version'. Thus, the
Linaro toolchains are released much more frequently than for Sourcery
toolchains. This blend of the version and patchlevel is the cause of
this discussion, I believe.
Two subsequent Linaro releases could be considered as two different
versions, or as one version but different patchlevel (in Sourcery
terminology). The classification used would determine what to do with
the buildroot config symbols (which ones to add and which to remove).

If it's a new 'version' we'd remove the oldest existing version and
add the new one.
If it's a new 'patchlevel', we'd remove the most recent toolchain of
the same 'version' (same combination of most important components) but
different 'patchlevel'.

This approach more or less requires different names of the config
symbols, unless we'd accept that config symbol LINARO_2013.11 could
actually install Linaro 2013.12 (example only).

Best regards,
Thomas
