Commit 34f95bf9db (toolchain-external: fix support of uClibc-ng toolchains,
2015-07-13) added the missing ld-uClibc.so.1 dynamic linker symlink that
binaries expect when linked with uClibc-ng. However on 64bit targets the
linker is called ld64-uClibc.so.1. Handle that case as well.

The uClibc-ng dynamic loader is called ld-uClibc.so.1, but gcc is not
patched specifically for uClibc-ng, so it continues to generate
binaries that expect the dynamic loader to be named ld-uClibc.so.0,
like with the original uClibc.
Therefore, when a uClibc-ng toolchain is used as an external
toolchain, we need to create an additional symbolic link to make
uClibc-ng systems work properly.

The toolchain from the Cavium Networks Octeon SDK provides a sysroot
with library directories lib32, lib32-fp, lib64 and lib64-fp. The -fp
variants are used for processors with hardware floating point unit, such
as the Octeon III variants.
When specifying -march=octeon3 in BR2_TARGET_OPTIMIZATION, the toolchain
will use lib32-fp, but currently Buildroot does not accept that pattern.
This patch improves the matching by accepting lib(32|64)?([^/]*)? as lib
directory name.

check_arm_abi builds a test C file to check that the toolchain is
working correctly, with the output redirected to /dev/null.
However, some toolchains (OSELAS 2014.12.0, for instance) foolishly
append ".gdb" to the output filename for an intermediate file, causing
an attempt to write to /dev/null.gdb, which obviously fails.
Fix this by adding changing the output to a temporary file, which is
later removed along with any other "suffixed" files.

The Linux kernel does force compile with -m4-nofpu, which is only
available when building a multilib toolchain.
The interesting part here is, that buildroot use --disable-multilib for
gcc configure, but enables --with-multilib-list=m4,m4-nofpu in
the default configuration for Qemu targeting r2d emulation.
This results in a toolchain, which can be used for the kernel and
for userland without creating a multilib toolchain with different
kinds of libgcc version. In the multilib case there would be
subdirectories created (!m4 and m4-nofpu). As buildroot uses a
short version of toolchain creation, a multilib enabled gcc build
fails when creating libgcc.
So the best solution is to just keep multilib disabled, but always
add --with-multilib-list when sh4/sh4eb/sh4a/sh4aeb is choosen.
Tested with sh4/sh4a toolchain build and qemu defconfig with
gcc 4.8.x/4.9.x (with and without C++ enabled), uClibc and glibc.
Disable sh4a/sh4aeb for uClibc, as it does not implemented, yet.

For Linaro toolchains, a special post install staging hook is used to
create two symlinks needed for the dynamic loader to find the

already exists and points to a directory:

ln: '/home/thomas/projets/outputs/training/target/lib/arm-linux-gnueabihf/.': cannot overwrite directory

For a multi-arch toolchain, gconv modules are in a sub-directory named
after the machine gcc targets. This is the case, for example, for the
Linaro ARM 2014.09 toolchain, which has the gconv modules in (relative
to the sysroot):
/usr/lib/arm-linux-gnueabihf/gconv
while the Sourcery CodeBench ARM 2014.05 (non-multi-arch) has them in:
/usr/lib/gconv
So, to catter for both cases, search both paths. We want to favour the
machine-specific gconv modules over potentially existing "generic" ones,
so we first search that (if it exists) and fallback to looking in the

Distro toolchains, i.ie. toolchains coing with distributions, will
almost invariably be unsuitable for use with Buildroot:
- they are mostly non-relocatable;
- their sysroot is tainted with a lot of extra libraries.
Especially, the toolchains coming with Ubuntu (really, all the Debian
familly of distros) are configured with --sysroot=/ which makes them
non-relocatable, and they already contain quite some libraries that
conflict (in any combination of version, API or ABI) with what Buildroot
wants to build (i.e. extra libraries, some not even present in
Buildroot...) but also their mere preence when Buildroot does not expect
them to be already built (so that a package would enable features when
it should not).
So, try to detect those toolchains and black-list them; inform the user
that the toolchain is unusable for the reasons mentioned above.

We currently only check that the Buildroot configuration matches what is
available in the toolchain.
Since we're going to remove the check for LFS and make it a mandatory
feature, we will lose the corresponding buildroot option, so we won't be
able to use check_uclibc_feature as-is.
Introduce a magic value passed as the buildroot option name to recognise
checks for mandatory uclibc options that do not have a corresponding
option in buildroot.
If the buildroot option name is empty then the check is against a
mandatory uclibc option.
If a mandatory uclibc option is missing we reject the toolchain as being
unusable by buildroot.

The computation of TOOLCHAIN_EXTERNAL_BIN has a special case for
Blackfin, where it's set to
$(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/$(TOOLCHAIN_EXTERNAL_PREFIX)/bin
instead of $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/bin for other
architectures.
However, this is actually only true for Analog Devices pre-built
toolchains. Other Blackfin external toolchains (such as ones built by
Buildroot) do not have this special organization.
Therefore, in order to make those non-ADI Blackfin toolchains work, we
need to change the condition from BR2_bfin to testing specifically for

Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.
Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.
To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.
[Thomas:
- Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
support in binutils. This is a blind option, selected by
BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
directly into gcc Config.in options.
- Remove the check on the AVR32 special gcc version, which we don't
support anymore.
- Adapt the help text of the LTO Config.in option to no longer
mention "Since version 4.5", since we only support gcc >= 4.5 in
Buildroot anyway.

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 CodeSourcery toolchains have a very interesting feature: they warn

This commit adds a similar functionality into our external toolchain

also be tuned as needed. By default, the external toolchain wrapper
now gives warnings such as:
arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-I /usr/foo'
arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-L /usr/bleh'
but the compilation continues successfully. One can then easily grep

Optionally, if BR_COMPILER_PARANOID_UNSAFE_PATH is defined in the

defines that the GOT ordering to be the same as the symbols ordering,
while GNU hash requires symbols to be sorted by their hash.
Looking at binutils' code, it seems that only MIPS suffers from that
limitation.
Currently, we force the toolchain wrapper to be linked with both hash
styles, which breaks on MIPS.
So, fix that by singling out MIPS, and use sysv in that case, and both
otherwise.

When the C library being used is uClibc, the locale support can be
disabled. In this case, it does not make sense to show the "Generate
locales" option.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Generating locales is possible in two situations:
- With the internal toolchain backend, when the uClibc library is
used. With uClibc, locales are generated at build time of the C
library, so with uClibc it's only possible with the internal
toolchain backend.
- With either the internal or external toolchain backend when the
glibc library is used. With glibc, locales can be generated
afterwards, using the host-localedef utility.
Until we had the musl C library supported in the internal toolchain
backend, the condition: BR2_TOOLCHAIN_BUILDROOT ||
BR2_TOOLCHAIN_USES_GLIBC was correct to capture the above two
situations. Now that we have musl support in the internal toolchain
backend, then BR2_TOOLCHAIN_BUILDROOT is incorrect, and we should use
BR2_TOOLCHAIN_BUILDROOT_UCLIBC instead.
Basic locale support in musl has appeared in musl 1.1.4, but we are
not yet capable of generating the locale files for musl.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

The fact that atomic operations are available is not really a
specificity of the toolchain, but rather of the architecture.
So, add a new option that architectures that have atomic operations
can select. This in turn selects the current toolchain atomic option,
until all packages have been converted, at which point the old
toolchain option can be removed.

GCC has several builtin functions that implement atomic operations. Those
functions are architecture specific and may not be implemented by the
specific toolchain. In case of GCC for ARC those functions rely on
LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't
support those instructions but software tries to use them, then application
will be aborted with Illegal instruction exception. To avoid confusion user
should first specify that their CPU supports atomic extension, which will
allow selection of packages that use builtin atomic functions.

As reported in bug #7172 [0], setting BR2_TARGET_LDFLAGS to a value
containing a $ sign can lead to unexpected results.
This is because it is very hard to know when the $ sign gets evaluated:
- in the Buildroot-level make
- in the shell called by the Buildroot-level make
- in the package's own build-system, either at configure time, in the
Makefile, in a shell in the Makefile...
So, it is very difficult to know how much escaping that would need.
A proposal is to use a shell variable to pass such values unmolested.
But it is not that simple either, since it still contains a $ sign, and
there is not much certainty as to when it would be evaluated.
Instead, just document this limitation, both in the help text for
BR2_TARGET_LDFLAGS, and in the known-issues section in the manual.
Does not really fix#7172, but at least the limitation is documented.

The gconv libraries are used to translate between different character sets
('charsets', even 'csets' sometimes). Some packages need them to present
text to the user (eg. XBMC Gotham).
In (e)glibc they are implemented by the internal implemenation of iconv,
called gconv, and are provided as dlopen-able libraries.
Note that some gconv modules need extra libraries (shared by more than
one gconv module), so we must, when adding a subset of modules, scan the
installed modules in search of the missing libraries.

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.

When getting the sysroot used for the kernel headers version check,
passing TOOLCHAIN_EXTERNAL_CFLAGS causes a problem when used with
multilib toolchains, where only the main sysroot has the header files,
and the other sysroots only have the libraries.
Since the kernel headers version used is normally the same for all
sysroots, this commit solves this problem by removing the
TOOLCHAIN_EXTERNAL_CFLAGS argument when calling
toolchain_find_sysroot, so that it returns the main sysroot, in which
<linux/version.h> can be found for the kernel headers version check.

Since the introduction of the kernel headers Config.in options, the
external toolchain logic had a check for custom external toolchains to
verify that the kernel headers version entered by the user matches the
one of the toolchain. However, this check was not made for non-custom
external toolchains (i.e the built-in profiles, such as Linaro,
CodeSourcery and al.), making the assumption that the Buildroot
developers will do the right selection.
However, it is quite nice when bumping external toolchains to have
this automatic kernel headers version check, to ensure we select the
appropriate kernel headers version.
Therefore, this commit makes the kernel headers version check
applicable to non-custom external toolchains.
