musl only uses PT_GNU_STACK to set default thread stack size and has no
executable stack support[0], so there is no reason not to emit the
.note.GNU-stack section on musl builds.

Subject: [PATCH] Include safe-ctype.h after C++ standard headers, to avoid
over-poisoning
When building gcc's C++ sources against recent libc++, the poisoning of
the ctype macros due to including safe-ctype.h before including C++
standard headers such as <list>, <map>, etc, causes many compilation
errors, similar to:

This is because libc++ uses different transitive includes than
libstdc++, and some of those transitive includes pull in various ctype
declarations (typically via <locale>).
There was already a special case for including <string> before
safe-ctype.h, so move the rest of the C++ standard header includes to
the same location, to fix the problem.
gcc/ChangeLog:
* system.h: Include safe-ctype.h after C++ standard headers.

Subject: [PATCH] riscv/linux: Don't add -latomic with -pthread
Now that we have support for inline subword atomic operations, it is no
longer necessary to link against libatomic. This also fixes testsuite
failures because the framework does not properly set up the linker flags
for finding libatomic.
The use of atomic operations is also independent of the use of libpthread.

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3

Subject: [PATCH] Include safe-ctype.h after C++ standard headers, to avoid
over-poisoning
When building gcc's C++ sources against recent libc++, the poisoning of
the ctype macros due to including safe-ctype.h before including C++
standard headers such as <list>, <map>, etc, causes many compilation
errors, similar to:

This is because libc++ uses different transitive includes than
libstdc++, and some of those transitive includes pull in various ctype
declarations (typically via <locale>).
There was already a special case for including <string> before
safe-ctype.h, so move the rest of the C++ standard header includes to
the same location, to fix the problem.

* system.h: Include safe-ctype.h after C++ standard headers.

Subject: [PATCH] riscv/linux: Don't add -latomic with -pthread
Now that we have support for inline subword atomic operations, it is no
longer necessary to link against libatomic. This also fixes testsuite
failures because the framework does not properly set up the linker flags
for finding libatomic.
The use of atomic operations is also independent of the use of libpthread.

* config/riscv/linux.h (LIB_SPEC): Don't redefine.

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

From dda6b050cd74a352670787a294596a9c56c21327 Mon Sep 17 00:00:00 2001

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3
