thrift builds perfectly fine on SPARC, which doesn't implement any of
the __sync built-ins, so we can get rid of the BR2_ARCH_HAS_ATOMICS
dependency.
The dependency on atomic operations originated in commit
1aaa14d84f ("thrift: disable for ARC"),
but there was no reference to any autobuilder failure. Our testing
with an ARC toolchain that doesn't have atomics shows that thrift
builds just fine, and code inspection also shows no usage of
__sync_*() built-ins. At the time of the commit, the thrift version
was 0.9.1, which also did not contain any __sync_*() call.

squid can use the __sync built-ins when available, but uses an
AC_TRY_RUN autoconf tests to check their availability, which isn't
compatible with cross-compilation. Due to this, squid.mk is already
hinting the configure script about this by passing
squid_cv_gnu_atomics=yes/no depending on the availability of atomic
operations.
So far, squid.mk was assuming that BR2_ARCH_HAS_ATOMICS &&
BR2_ARCH_IS_64 was needed, since 8 bytes __sync built-ins are
used. However, this was a bit too restrictive, since certain 32 bits
architectures (ARM, x86) do provide 8 bytes __sync built-ins.
So, instead of using BR2_ARCH_HAS_ATOMICS, we now rely on
BR2_TOOLCHAIN_HAS_SYNC_4 and BR2_TOOLCHAIN_HAS_SYNC_8, since both 4
bytes and 8 bytes __sync built-ins are tested by the autoconf test.

This commit handles the reverse dependency tree of cairo in terms of
atomic dependencies. There are two main changes:
- cairo in fact no longer needs atomic operations. It can perfectly
build without any __sync built-in, as was tested using an ARC
toolchain without atomics, and a SPARC toolchain. Optionally, Cairo
can use the __atomic builtins provided by gcc >= 4.7, so support
for this is added as well. Thanks to this change, the
BR2_ARCH_HAS_ATOMICS dependency is removed from cairo and all its
reverse dependencies.
- harfbuzz does require the __sync built-in for 4 bytes integers, so
we add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 to harfbuzz and all
its reverse dependency, the main one being the pango package. Due
to this, the vast majority of gtk-related packages are moved to a
dependency on BR2_ARCH_HAS_ATOMICS (which used to be due to cairo)
to a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 (due to pango ->
harfbuzz).
In detail:
- cairo
Remove BR2_ARCH_HAS_ATOMICS dependency, link against -latomic when
gcc >= 4.8 in order to use the __atomic functions.
- harfbuzz
Add dependency on BR2_TOOLCHAIN_HAS_SYNC_4
- cairomm, gst-plugins-good, gst1-plugins-good, libgdiplus,
libsvg-cairo, weston
Remove BR2_ARCH_HAS_ATOMICS dependency (since cairo no longer needs
atomics)
- enlightenment, cwiid, gst-plugins-bad, gst-plugins-base,
gst1-plugins-bad, gst1-plugins-base, gtkmm3,
libevas-generic-loaders, libfm, libgail, libgtk2, libgtk3, librsvg,
openbox, opencv, opencv3, pango, pangomm, pcmanfm, pinentry,
rrdtool, webkit, webkitgtk24, xscreensaver
Switch from a BR2_ARCH_HAS_ATOMICS dependency to a
BR2_TOOLCHAIN_HAS_SYNC_4 (they depend on pango, harfbuzz, gtk, or
some other related package)
- directfb
Remove BR2_ARCH_ATOMICS dependency of the BR2_PACKAGE_DIRECTFB_SVG
(since cairo can build without atomics), but add a
BR2_TOOLCHAIN_HAS_SYNC_4 dependency on BR2_PACKAGE_DIRECTFB itself
since it does use __sync built-ins. This replaces the !BR2_sparc

gauche does not build on sparc64, it fails with:
No rule to make target 'sparc_mach_dep.lo', needed by 'libgc.la'
On Sparc, it first fails with the usual "membar" assembler issue which
comes from gauche's internal version of libatomic_ops. However, even
passing -DAO_NO_SPARC_V9 like we do for libatomic_ops is not
sufficient, as we fall into the same build problem as on sparc64.
Consequently, this commit disables the gauche package on the sparc and
sparc64 architectures.
Since it uses its own libatomic_ops copy, and libatomic_ops does not
have any dependency on atomic built-ins, we also remove the
BR2_ARCH_HAS_ATOMICS dependency. It was originally added to prevent
gauche from being built on sparc, but this will no longer happen.

Since the apache package was introduced,
--enable-nonportable-atomics=yes was passed when
BR2_ARCH_HAS_ATOMICS. However, Apache doesn't take this option: it
only passes it down when building the APR library. But since we're
building APR separately, this statement had no effect.
So this commit removes the useless code from the Apache package, and

pulseaudio is able to either use the atomic __sync builtins from the
compiler, or to rely on libatomic_ops for atomic operations. However,
since it anyway selects json-c which requires the __sync built-ins, it
means using libatomic_ops is useless: even if you use libatomic_ops
for pulseaudio, you'd still get a link error in pulseaudio due to the
missing __sync built-in for the json-c library.
Also, since pulseaudio now inherits the BR2_TOOLCHAIN_HAS_SYNC_4 from
json-c, which matches the __sync built-in from pulseaudio, this
commit:
- Drops the BR2_ARCH_HAS_ATOMICS dependency
- Forces pulseaudio to not detect libatomic_ops
- Propagates the removal of BR2_ARCH_HAS_ATOMICS dependency to
pulseaudio's reverse dependencies.

While json-c itself builds fine on platforms that don't provide the
__sync atomic built-ins, it does use them. json-c doesn't fail to
build because only a library is built, so such function calls are left
unresolved. But as soon as it gets used in another package linked in a
program, linking will fail due to the missing
__sync_val_compare_and_swap_4() function.
To fix this, we make json-c depend on BR2_TOOLCHAIN_HAS_SYNC_4, and
propagate to the reverse dependencies:
- json-c
- fastd
- pulseaudio
- efl
- espeak
- gst-plugins-good

Note that pulseaudio already had a BR2_ARCH_HAS_ATOMICS dependency,
which we are keeping for the moment, and will clean-up in a subsequent
commit.
This commit will also fix packages that could optionally use json-c,
and therefore fixes build failures like:

This commit updates the documentation to detail when and how to use
the BR2_TOOLCHAIN_HAS_SYNC_x dependency. Note that we chose to not add
a comment about this dependency, because it is mainly tied to
architecture capabilities (except in very specific cases, which would
be way too complicated to explain in a Config.in comment).
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Currently, Buildroot provides one BR2_ARCH_HAS_ATOMICS boolean option
to indicate whether the architecture supports atomic operations or
not. However, the reality of atomic operations support is much more
complicated and requires more than one option to be expressed
properly.
There are in fact two types of atomic built-ins provided by gcc:
(1) The __sync_*() family of functions, which have been in gcc for a
long time (probably gcc 4.1). They are available in variants
operating on 1-byte, 2-byte, 4-byte and 8-byte integers. Some
architectures implement a number of variants, some do not
implement any, some implement all of them.
They are now considered "legacy" by the gcc developers but are
nonetheless still being used by a significant number of userspace
libraries and applications.
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fsync-Builtins.html
(2) The __atomic_*() family of functions, which have been introduced
in gcc 4.7. They have been introduced in order to support C++11
atomic operations. In gcc 4.8, they are available on all
architectures, either built-in or in the libatomic library part
of the gcc runtime (in which case the application needs to be
linked with -latomic). In gcc 4.7, the __atomic_*() intrinsics
are only supported on certain architectures, since libatomic did
not exist at the time.
For (1), a single BR2_ARCH_HAS_ATOMICS is not sufficient, because
depending on the architecture, some variants may or may not be
available. Setting BR2_ARCH_HAS_ATOMICS to false as soon as one of the
variant is missing would cause a large number of packages to become
unavailable, even if they in fact use only more common variants
available on a large number of architectures. For this reason, we've
chosen to introduce four new Config.in options:
- BR2_TOOLCHAIN_HAS_SYNC_1
- BR2_TOOLCHAIN_HAS_SYNC_2
- BR2_TOOLCHAIN_HAS_SYNC_3
- BR2_TOOLCHAIN_HAS_SYNC_4
Which indicate whether the toolchain support 1-byte, 2-byte, 4-byte
and 8-byte __sync_*() built-ins respectively.
For (2), we introduce a BR2_TOOLCHAIN_HAS_ATOMIC, which indicates if
the __atomic_*() built-ins are available. Note that it is up to the
package to link with -latomic when gcc is >= 4.8. Since __atomic_*()
intrinsics for all sizes are supported starting
We conducted a fairly large analysis about various architectures
supported by Buildroot, as well as with a number of different
toolchains, to check which combinations support which variant. To do,
we linked the following program with various toolchains:
int main(void)
{
uint8_t a;
uint16_t b;
uint32_t c;
uint64_t d;
__sync_fetch_and_add(&a, 3);
__sync_fetch_and_add(&b, 3);
__sync_fetch_and_add(&c, 3);
__sync_fetch_and_add(&d, 3);
__sync_val_compare_and_swap(&a, 1, 2);
__sync_val_compare_and_swap(&b, 1, 2);
__sync_val_compare_and_swap(&c, 1, 2);
__sync_val_compare_and_swap(&d, 1, 2);
__atomic_add_fetch(&a, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&b, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&c, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&d, 3, __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&a, &a, 2, 1, __ATOMIC_RELAXED, __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&b, &b, 2, 1, __ATOMIC_RELAXED, __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&c, &c, 2, 1, __ATOMIC_RELAXED, __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&d, &d, 2, 1, __ATOMIC_RELAXED, __ATOMIC_RELAXED);
return 0;
}
And looked at which symbols were unresolved. For the __atomic_*()
ones, we tested with and without -latomic to see which variants are
built-in, which variants require libatomic. This testing effort has
led to the following results:

Notes:
* __atomic built-ins appeared in gcc 4.7, so for toolchais older than
that, the __atomic column is empty.
* Y means 'supported built-in'
* L means 'supported via linking to libatomic' (only for __atomic
functions)
* X indicates a very special case for 8 bytes __sync built-ins on
ARM. On ARMv7, there is no problem, starting from gcc 4.7, the
__sync built-in for 8 bytes integers is implemented, fully in
userspace. For cores < ARMv7, doing a 8 bytes atomic operation
requires help from the kernel. Unfortunately, the libgcc code
implementing this uses the __write() function to display an error,
and this function is internal to glibc. Therefore, if you're using
glibc everything is fine, but if you're using uClibc or musl, you
cannot link an application that uses 8 bytes __sync
operations. This has been fixed as part of gcc PR68095, merged in
the gcc 5 branch but not yet part of any gcc release.
* - means not supported
This commit only introduces the new options. Follow-up commits will
progressively change the packages using BR2_ARCH_HAS_ATOMICS to use
the appropriate BR2_TOOLCHAIN_HAS_SYNC_x or BR2_TOOLCHAIN_HAS_ATOMIC
until the point where BR2_ARCH_HAS_ATOMICS can be removed.

For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
- a standard upstream version string vX.Y.Z
- a non-standard version string, but still containg the standard X.Y.Z
Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.
There are a few cases were there was a mismatch:
- microzed: uses a 3.18 kernel, but 3.8 headers; fixed.
- xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
- zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.

When libbsd still supported uClibc as a C library, we added the architecture
exclusions because uClibc's a.out.h includes linux/a.out.h. The latter only
exists for the specified architectures.
However, glibc doesn't include linux/a.out.h, it instead has its own
implementation and it adds a flag to indicate if a.out is supported on this
architecture or not.
Since libbsd currently only supports glibc-based toolchains, the architecture
exclusions are no longer valid.
On microblaze, the build still fails, but this time because of ELF support.
libbsd explicitly handles architectures and microblaze is not one of them (see
