This commit backports the patch "fixinc: don't "fix" machine names in
__has_include(...)" from upstream GCC, which is needed to resolve a
header conflict between glibc headers and kernel headers, which has
appeared since we bumped glibc to version 2.36 in commit
80c8c15c85.
The problem comes from the "fixinc" logic used by gcc to fixup some
headers files, generated inside an include-fixed/ folder. This logic
ended up replacing "linux/mount.h" by "__linux__/mount.h" in
__has_include() invocation, like this:
#ifdef __has_include
# if __has_include ("__linux__/mount.h")
# include "linux/mount.h"
# endif
#endif
in
build/host-gcc-final-11.3.0/build/gcc/include-fixed/sys/mount.h. With
this fix in place, this "include-fixed" header is no longer generated,
avoiding the problem.
This issue was visible in two different ways in glibc configurations:
- As a build failure during the gcc build itself, for architectures
that support libsanitizer, as libsanitizer includes mount.h, and
would therefore encounter the header conflict.
- As a build failure during another user-space package (such as
sysvinit for example), on architectures when libsanitizer isn't
used, and therefore for which the gcc build was successful, but the
header conflict shows up when building some "random" user-space
package.
The problem is already fixed in GCC 12.2.0, so no patch is
required. The problem did not exist back in GCC 8.4.0, so this version
does not need patching. Consequently, the patch is only needed for GCC
10.4.0, GCC 11.3.0 and the special ARC 2020.09-release version.

Currently, this option doesn't do anything. It only adds
--enable-plugins --enable-lto to the configure flags, but doesn't
disable them if it is not set. Since both of these default to enabled,
plugins and lto are effectively always enabled.
There really is no need to make this configurable: it adds a bit of size
and build time to host-gcc, but we don't care about that for host tools.
It's still up to individual builds to enable the LTO options.
Therefore, remove the option entirely. For clarity, explicitly pass
--enable-plugins --enable-lto to configure.
No legacy handling is added for the removed option. Since the behaviour
hasn't actually changed (independently of whether the option was enabled
or not), there's no point bothering the user with a legacy option.
elf2flt was linking with libdl depending on this option. Since the
option doesn't do anything, this is probably not needed. Still, to avoid
breaking things, and because linking with libdl doesn't cost us anything
anyway, always link with libdl.

When BR2_TOOLCHAIN_HAS_LIBQUADMATH is set, --enable-libquadmath-support

This will use gcc-ar, gcc-nm and gcc-ranlib instead of the
normal binutils tools. The difference is that with the
wrappers, gcc plugins will be automatically picked up,
which is necessary to build with LTO.
With this enabled, it is possible to build everything (including libgcc
and libstdc++) with LTO by setting BR2_TARGET_OPTIMIZATION="-flto".
Note that you'd expect that the GCC build system would automatically do
this when --enable-lto is set, but this is not the case. There are some
open bugs [1][2] to allow building libgcc and libstdc++ with LTO support
but it's apparently not done yet.
Note that there are also reports of problems building libstdc++ with LTO
[3], but it seems that's no longer a problem (and the bug didn't get
updated).

GCC support enabling secureplt for powerpc64.
From [1]
"PowerPC has two PLT models: BSS-PLT and Secure-PLT. BSS-PLT uses
runtime code generation to generate the PLT stubs. Secure-PLT was
introduced with GCC 4.1 and Binutils 2.17 (base has GCC 4.2.1 and
Binutils 2.17), and is a more secure PLT format, using a read-only
linkage table, with the dynamic linker populating a non-executable
index table."
This option is always enabled by glibc testing script
called build-many-glibcs.py [1]. This script exist since
glibc 2.25.

As we many times by now discussed that - some ARC cores might
not have atomic instructions implemented. Namely that's ARC700
w/o explicitly added atomics during design creation/configuration.
Because of that when GCC gets configured for ARC700, i.e. via
"--with-cpu=arc700" atomic ops are assumed disabled.
Usually it's not a problem as we add "-matomics" in the wraper for
building all packages if targets CPU has atomis (BR2_ARC_ATOMIC_EXT).
But when bulding target's binaries which are essential parts of
the GCC itself we don't use the wrapper. Instead xgcc is being used.
That way we lose that important part of system's configuration about
atomics and:
1. Atomic ops won't be used where otherwise they could have been used.
2. Some configuration checks might end-up thinking there're no atomics
In particular (2) leads to pretty obscure failure on bulding of some
packages which use C++, for example:

and since then we started to see that new breakage which we now
attempt to fix right where it hapens on GCC configuration.
In contrast ARC HS family has atomic ops enabled by default thus
we never spotted that kind of problem for it.

The GCC-7.x compiler series was the last to officially support PowerPC
SPE CPUs. Now that GCC-8.x is the default compiler used by Buildroot,
some defconfigs, notably the arcturus_ucp1020_defconfig and
freescale_p1025twr_defconfig ones started to fail building, as they
are PowerPC SPE platforms.
In fact, the GCC-8.x compiler series continues to support PowerPC SPE
CPU cores, but only as an --enable-obsoleted instruction set. This
patch enables the use of GCC-8.x and asserts the required option to
enable the PowerPC SPE instruction set.
This patch passes compilation and run tests with the
arcturus/ppc-ucp1020 board.
This patch should address a noted job failure on GitLab CI

The GCC package has a default conf option of disabling libquadmath and
the toolchain dependencies selectively enabled it if i386 / x64.
Fixes:
https://gitlab.com/bootlin/toolchains-builder/-/jobs/729359622
This patch fixes a build failure when (GCC + glibc) is being built for
the IBM Power8 arch and has libgfortran enabled + libquadmath disabled.
The libgfortran has a code condition for __float128 and includes the
quadmath headers. The bug occurs because Power8 has emulated
float128 support. The fix per GCC options is to also set
--disable-libquadmath-support which disables the
__float128/libquadmath support in gcc/fortran and in libgfortran [1].
Another option to fix the build failure was to enable libquadmath for
IBM Power8 (ISA 2.07), however this would be soft float based as the
ISA 3.0+ (Power9) first supports native float128 [2][3].

gcc 10.2 is around, gcc 9.3 is the default version, so drop
7.5 in order to reduce the gcc choice.

We used to have a conditional patch applied on PowerPC soft-float, but
this logic was dropped in commit
0c82f3f635 ("package/gcc: remove powerpc
conditional patching logic"). However, we still have some related
leftovers in the calculation of the hashes for ccache, which can now
be dropped.
