this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng015.
This tag introduces following changes:
1. binutils: Rebase onto upstream master.
2. gcc: Fix devdf3 emulation for arcem, disable TP register when
building for bare metal.
We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.
So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

gcc 4.9.4 was the last release of the 4.9.x branch, and the gcc
developes will now only be maintaining gcc 5.x and 6.x:
https://gcc.gnu.org/ml/gcc-announce/2016/msg00002.html
Therefore, it is time to use gcc 5.x as the default version in
Buildroot. We have been having toolchains in the autobuilders with gcc
5.x for a while, so the vast majority of the problems should have
already been solved.

The ARC gcc version is now based on gcc 6.x and no longer gcc 4.8.x,
which makes the option BR2_GCC_VERSION_4_8_ARC a bit irrelevant, as is
the prompt of this option.
This commit therefore renames this option to BR2_GCC_VERSION_ARC, and
adjust its prompt as well.

The current BR2_GCC_ENABLE_TLS can cause users to make incorrect
choices, and is not very useful. This options allows to decide whether
we pass --enable-tls or --disable-tls to gcc, to enable or disable
support for Thread Local Storage.
Its behavior is:
- The option is default to "y" but only exists if we're using
uClibc/NPTL or glibc.
- When we're using uClibc, the option can be disabled.
So, in practice, this means that currently:
- TLS support is always on for glibc
- TLS support is on by default for uClibc/NPTL, but can be disabled in
the configuration. This is in fact bad and causes the build failure
reported in bug #7424 (this bug is still reproducible on master)
- TLS support is always disabled for uClibc/no-thread and
uClibc/linuxthreads.
- TLS support is always disabled for musl. This does not cause any
build failure, but musl can use TLS support, and therefore be more
efficient. According to
http://www.openwall.com/lists/musl/2012/10/04/1, "Note that if you've
been building gcc with --disable-tls, __thread was already working
but gets emulated (very poorly; it's slow and will abort() if it runs
out of memory) through libgcc.".
So, this commit completely removes the BR2_GCC_ENABLE_TLS and instead
makes the right choice inside gcc.mk directly:
- TLS support enabled for glibc, musl and uClibc/NPTL
- TLS support in other cases, i.e uClibc/no-thread and
uClibc/linuxthreads.
We have intentionally *not* added the option to
Config.in.legacy. Indeed, the new behavior is *exactly* the same as the
older behavior, with the exception of:
- People can no longer disable TLS support in uClibc/NPTL, which was
anyway causing a build failure and therefore was not used.
- TLS support is now enabled on musl, but people using musl already had
BR2_GCC_ENABLE_TLS not set, so they wouldn't get the legacy warning.
Fixes bug #7424.

In commit
5ab751ca44 ("toolchain-buildroot: allow to
build ppc64(le) musl toolchains"), support for building a musl toolchain
for ppc64(le) was added. Since this support only works with gcc 6, some
additional dependencies have been added to the older gcc versions so
that they cannot be selected on ppc64(le)/musl.
Unfortunately, the expression of the dependency was wrong, and leads to
those older gcc versions being non-selectable if you're not using
musl. Indeed, the dependencies look like this:
depends on !BR2_powerpc64 && !BR2_powerpc64le && BR2_TOOLCHAIN_USES_MUSL
So as soon as you're not using musl, BR2_TOOLCHAIN_USES_MUSL is false,
so the entire condition is false, and the gcc version is not available.
Due to this, only gcc 6.x can be selected currently with uclibc or
glibc, which is clearly not the intended behavior.
This commit reworks those dependencies to:
depends on !(BR2_TOOLCHAIN_USES_MUSL && (BR2_powerpc64 || BR2_powerpc64el))
which more clearly expresses what we want:
"We don't want to (have a toolchain that uses musl and (be building
either for PPC64 or PPC64le))"

The three patches allow to compile applications using TLS emulation from
libgcc or C++ applications.
The patches 892-libgcc-mkmap-symver-support-skip_underscore.patch and
893-libgcc-config-bfin-use-the-generic-linker-version-in.patch fixes how
libgcc is generated, by making the necessary libgcc symbols declared
"GLOBAL", and therefore visible outside of libgcc. This fixes a large
number of undefined reference issues (for either C++ applications or
applications using TLS emulation). This was reported as gcc PR74748.
The patch 894-libgcc-fix-DWARF-compilation-with-FDPIC-targets.patch
allows to build DWARF in FDPIC mode. This patch replaces the older
892-disable-dwarf-bfin.patch, as instead of disabling DWARF support, it
fixes it. This was reported as gcc PR68468.
In order to get C++ working without unresolved symbols, we also need to
disable symbol versioning (--disable-symvers). This is a remaining issue
in gcc which will be investigated at a later point.
Since this commit fixes C++ support in Blackfin, it re-enables the
selection of C++ support for this architecture.

Latest musl release supports ppc64 architecture (both big endian and
little endian), so this commit adds support for this.
Since musl implements the ELFv2 ABI for both big-endian and
little-endian PowerPC64, we have to force using this ABI on PowerPC64
big endian (normally elfv1 is the default).
Also, only gcc 6.x has the necessary changes to support musl on PowerPC
64, so we restrict the gcc version selection accordingly.
Tested with Qemu for big endian and little endian configurations.

4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng008.
Main updates were made for gcc. It was switched to GCC 6 and to
OSABI v4.
Besides this patch fixes buildroot ARC failures connected to
"crtbeginT.o" object file missing. This issue lead to two main errors:
1) "crtbeginT.o: No such file or directory", e. g. bootutils-1.0.0.
No comments are required here I hope.
2) Errors like "compiler cannot create executables", e.g.:
a) host-gcc-final-arc-2016.09-eng007 static build,
b) aespipe-2.4c.
That was caused because the test to determine if compiler is able to
create executables was failing due to missing "crtbeginT.o" file.
We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

As discussed with Waldemar, the C++ support for Blackfin is currently
broken, and we don't have a fix in sight for the 2016.08
release. Therefore, this commit disables C++ support entirely on the

This will avoid a significant number of Blackfin build failures, that

With this commit we're starting a series of updates of ARC tools.
Significantly rewritten arc-2016.03 tools introduced way too many
problems highlighted by Buildroot autobuilder. Now in attempt to
resolve as many issues as possible by the time final release of
arc-2016.09 tools is cut we'll be executing arc-2016.09 series
with engineering snapshots like this one.
We decided to go this way instead of applying separate patches here
and there because ongoing development introduces quite a lot of
changes and separate patches are not practical in Buildroot.
Moreover this will give us very clean visibility of number of
issues we see (hopefully it will decrease over time).
One of the important changes introduced in this engineering build
is initial set of changes for proper support of PIE on ARC in terms
of both building on host and running on ARC target. I expect some
PIE-related build breakages to go away and new ones will be treated
as the high-priority issues to be fixed ASAP.
For now we only update Binutils and GCC while keeping GDB
as it is of arc-2016.03 release because there're some issues
we'd like to resolve before releasing it to wider audience.
So again note this is one of the first engineering builds of
arc-2016.09 series and it might have all kinds of breakages,
please don't use it for production builds.

In commit f4682cf933, a hash of the patches applied to gcc was created
to make sure that ccache can properly detect when the toolchain has
changed. The patches applied to gcc consist of the buildroot patches in
package/gcc, but also potentially patches in BR2_GLOBAL_PATCH_DIR.
However, the path to the patches in BR2_GLOBAL_PATCH_DIR was corrected
incorrectly, because it misses a /. So instead of:
$(BR2_GLOBAL_PATCH_DIR)/gcc-initial/*.patch
it would look for
$(BR2_GLOBAL_PATCH_DIR)gcc-initial/*.patch
In other words, if BR2_GLOBAL_PATCH_DIR doesn't end with /, the patches
in BR2_GLOBAL_PATCH_DIR are not taken into account in the ccache hash.
To fix, add the missing /

After the commit f67a4f50e2 "gcc: preserve CXXFLAGS_FOR_TARGET"
target CFLAGS are passed to all libraries bundled with gcc. This breaks
libsanitizer on gcc-4.9.x when building with _FILE_OFFSET_BITS=64:
error: size of array ‘assertion_failed__837’ is negative
...
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:837:1:
note: in expansion of macro ‘CHECK_SIZE_AND_OFFSET’
CHECK_SIZE_AND_OFFSET(dirent, d_ino);
This issue is fixed in the libsanitizer mainline and in gcc-5.x.
There's no issue with gcc-4.8.x and earlier.
