LTO object files will now be compressed using zstd.
Compressing debug sections with zstd will have to wait for GCC 13,
which adds support for -gz=zstd.
NOTE: wiping the ccache is strongly recommended, not doing so might
yield build error later on:
"lto1: internal compiler error: original not compressed with zstd"

Instead of having two different ways to pass flags to the gcc build
process, add them as configure args, which is a reliable way to let
gcc pass them around to its various pieces.
Also add CXXFLAGS, since gcc started to use c++ for itself recently
(~10 years ago now).

Every minor version bump of a major version will result in a huge patch
diff because of the moving of all the patches from version e.g. 11.2.0 to
11.3.0. This commit only use the major version for the patch folders to
differentiate between the different gcc versions. This will significantly
improve the reviewing of the smaller version bump patches and help to see
what really changed in a minor version bump.

At configuration time, gcc assumes that ppc64be targets use the ELFv1
ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not
support the ELFv1 ABI on ppc64 at all, regardless of the endianness.
Therefore, when building for a ppc64 arch and with musl libc, instruct
gcc to use the ELFv2 ABI.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93157 for more info.

GCC 5.1 changed the std::string ABI in order to properly support C++11.
For compatibility with libraries compiled with the older ABI, that is,
linking between old-abi.so and new-abi.bin, both ABIs are enabled. In
terms of OpenWrt, all packages are compiled with the same toolchain,
which means these issues do not need to be handled.
Most importantly, this results in a significant size reduction of
libstdpp:
Before:
450794 bytes
After:
327752 bytes
Tested with all OpenWrt packages.

Removes the standalone implementation of stack smashing protection
in gcc's libssp in favour of the native implementation available
in glibc and uclibc. Musl libc already uses its native ssp, so this
patch does not affect musl-based toolchains.
Stack smashing protection configuration options are now uniform
across all supported libc variants.
This also makes kernel-level stack smashing protection available
for x86_64 and i386 builds using non-musl libc.

This problem exposed when compiling glibc, but applicable across the
board. gcc compiles runtime libraries for all supported architectures,
unless otherwise specified, and later selects applicable library based
-m[arch,cpu,*] options, thus these options should not be passed to gcc
as they break the compilation process.

[modified so it only touches ARM - I'm too chicken, changed authors email]
Set the toolchain's ARM CPU and FPU architectures by utilizing' gcc's
--with-cpu / --with-fpu configure options that: "Specify which cpu
variant the compiler should generate code for by default. cpu will
be used as the default value of the -mcpu= switch."
This will resolve the following kernel compilation failures under
gcc 8.x on ARM because the kernel wants to set (possibly conflicting)
optimization flags.
.../ccyVnmrs.s:204: Error: selected processor does not support `dmb ish' in ARM mode
.../ccyVnmrs.s:215: Error: architectural extension `mp' is not allowed for the current base architecture
.../ccyVnmrs.s:216: Error: selected processor does not support `pldw [r4]' in ARM mode
Because this is a big change, the .config and toolchain need to be
refreshed (as in removed and regenerated).

Changes compared to GCC 7.x
001-revert_register_mode_search.patch dropped
The underlying issue is described at the end of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58139
It is fixed by the upstream commit:
3fa2798aa8
020-PR-libstdc-81797-Add-.NOTPARALLEL-to-include-Makefil.patch dropped due to already upstream
100-PR-rtl-optimization-83496.patch dropped due to already upstream
910-mbsd_multi.patch
modified to fix ambiguous overloaded inform() call error
gcc/input.h
header: define UNKNOWN_LOCATION ((source_location) 0)
- inform (0, "someone does not honour COPTS correctly, passed %d times",
- honour_copts);
+ inform (UNKNOWN_LOCATION, "someone does not honour COPTS correctly, passed %d times",
+ honour_copts);
940-no-clobber-stamp-bits.patch dropped due to fixed upstream by another way
upstream commit: 87b2d547f8
950-cpp_file_path_translation.patch dropped, Both -fmacro-prefix-map and -ffile-prefix-map are added
to gcc 8.1.0, if I understand it correctly, we should use -fmacro-prefix-map
usage: -fmacro-prefix-map=@var{old}=@var{new}
upstream commit: 859b51f836
-iremap exists as a flag for a long time, for backward compatibility, I think we should keep the
variable name unchanged but change its value in rules.mk for gcc 8.x and higher.

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.
