Currently the CodeSourcery toolchains for MIPS can be selected to build
mips32 (revision level 1) targets, but the resulting binaries are built
for mips32r2 instead. This is because these toolchains don't have
library support other than mips32r2, so there is no point to allow the
selection of a mips32 variant with a CodeSourcery MIPS toolchain, since
everything will be built for mips32r2 instead.

This commit wires up the gcc version dependency mechanism in the
external toolchain backend. To do so, it:
* Changes the definition of all pre-defined external toolchain
profiles to select the appropriate BR2_TOOLCHAIN_GCC_AT_LEAST_*
option.
* For custom external toolchains, provides a visible Config.in
"choice" to select the gcc version used in the external toolchain.
* Adds a new check_gcc_version function, that verifies that the real
gcc version found in the external toolchain matches the one
declared in the Buildroot configuration.

This uClibc toolchain does not provide an appropriate uClibc

we remove all the quirks that were introduced to start work around

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

The 2014R1 toolchain is provided in two flavours by Analog Devices:
one based on gcc 4.3.x, which is considered stable, and one based on
gcc 4.5.x, considered experimental. In commit
5a65b8e185 ("toolchain-external: add ADI
Blackfin 2014R1 toolchain, remove 2012R1") both variants were added.
However, after some testing in the autobuilders, and discussion with
the Analog Devices folks, it turns out that the experimental version
of the toolchain is too experimental. It causes numerous build
failures, and the Analog Devices folks clearly say that it's an early
release and that they expect quite a few problems to show up.
Therefore, this commit removes the experimental flavor and keeps only
the stable variant. Note that the removal/renaming of the Config.in
options is not a problem, since those options were added after the
2014.05 release.

This hidden option is:

* Automatically enabled when an internal uClibc toolchain with NPTL
support is configured. It is left disabled otherwise for internal

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.
A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of

The introduction of the EABIhf ABI requires a few updates to the
configuration options for external toolchains, in order to ensure that
the user doesn't do any invalid selection. In detail:
* The Linaro ARM toolchains now depend on BR2_ARM_EABIHF, because
that's the ABI they use, and it is incompatible with EABI. The
comment about the availability of Linaro toolchains is updated to
inform users selecting EABI that they should select EABIhf if they
want to see Linaro toolchains.
* The Sourcery CodeBench toolchains now depend on BR2_ARM_EABI,
because that's the ABI they use. A comment is added to inform users
that have selected EABIhf that Sourcery CodeBench are only
available when EABI is used.
* The Arago toolchains now depend on BR2_ARM_EABI, because that's the
ABI they use. The description of the ARMv7 Arago toolchain is also
slightly improved.

Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.
Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

For certain situations, users may want to install shared FLAT
libraries to the target filesystem even if FDPIC is used as the
primary binary format, or symmetrically users may want to install FDPIC
libraries to the target filesystem even if shared FLAT is used as the
primary binary format.
This commit allows that by:
* Offering additional Kconfig options to install shared FLAT or FDPIC
libraries even when those libraries are not selected as the primary
binary format.
* Preserving all Blackfin toolchain folders under the
TOOLCHAIN_EXTERNAL_DIR, instead of keeping only the one related to
the selected binary format.
* Adding some additional install targets that do the installation of
either the shared FLAT or FDPIC libraries when requested.

Instead of a long list of the ARMv7-A Cortex-A, use a conditional
based on BR2_GCC_TARGET_ARCH to hide/show toolchains that are only
usable on ARMv7-A.
However, in the comment related to Linaro toolchains, we keep
mentioning Cortex-A{5,8,9,15} because that's what users see when they

This commit converts gdb to the package infrastructure, and therefore
moves it from toolchain/gdb to package/gdb.
The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.
The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.
Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

The existing Microblaze toolchains that we have have the annoying
property of being based on a very old glibc version: 2.3.6. Xilinx
provides newer toolchains with glibc 2.14, generated by Crosstool-NG,
but they are only available as part of a huge Git repository that
contains the gcc, Linux, binutils, glibc sources unpacked (4.4 GB
total), which makes is very unpractical.
I contacted the Xilinx person who did those toolchains, but they
apparently didn't intend to change that anytime soon.
So, we have created a tarball for those toolchains, adding a
README.txt file in the tarball that points back to the original
location that contains the source code for them. Those tarballs are
hosted on sources.buildroot.net.
This commit then adds support for those two new external toolchains,
one for little endian Microblaze, another one for big endian
Microblaze.

Basically, the BR2_TOOLCHAIN_EXTERNAL_GLIBC option no longer
unconditionally selects BR2_TOOLCHAIN_HAS_NATIVE_RPC since there are
glibc toolchains that don't have RPC support. All the predefined
toolchain profiles are updated to take into account this change: for
the moment, all glibc toolchains that have pre-defined toolchains have
RPC support, but further patches in the series add pre-defined glibc
toolchains that don't have RPC support. In the case of custom glibc
toolchains, a question is asked to the user so that he can say whether
the external glibc toolchain has RPC support or not. The validity of
this configuration option is checked by the new
check_glibc_rpc_feature function in helpers.mk.
