-Subject: [PATCH] ranger: Fix up fold_using_range::range_of_address [PR103255]
-
-If on &base->member the offset isn't constant or isn't zero and
--fdelete-null-pointer-checks and not -fwrapv-pointer and base has a range
-that doesn't include NULL, we return the range of the base.
-Usually it isn't a big deal, because for most pointers we just use
-varying, range_zero and range_nonzero ranges and nothing beyond that,
-but if a pointer is initialized from a constant, we actually track the
-exact range and in that case this causes miscompilation.
-As discussed on IRC, I think doing something like:
- offset_int off2;
- if (off_cst && off.is_constant (&off2))
- {
- tree cst = wide_int_to_tree (sizetype, off2 / BITS_PER_UNIT);
- // adjust range r with POINTER_PLUS_EXPR cst
- if (!range_includes_zero_p (&r))
- return true;
- }
- // Fallback
- r = range_nonzero (TREE_TYPE (gimple_assign_rhs1 (stmt)));
- return true;
-could work, given that most of the pointer ranges are just the simple ones
-perhaps it is too much for little benefit.

- 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

-Subject: libstdc++: Add -nostdinc++ for c++17 sources [PR100017]
-X-Git-Tag: releases/gcc-11.3.0~445
-X-Git-Url: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff_plain;h=01a70ccd723eb9a479186fe37c972b0d0f8676cf
-
-libstdc++: Add -nostdinc++ for c++17 sources [PR100017]
-
-When building a build!=host compiler, the just-built gcc can't be used
-to build the target libstdc++ (because it is built for the host triplet,
-not the build triplet). The top-level configure.ac sets up the build
-flags for libstdc++ (and other "raw_cxx" libs) like this:
-
-GCC_TARGET_TOOL(c++ for libstdc++, RAW_CXX_FOR_TARGET, CXX,
- [gcc/xgcc -shared-libgcc -B$$r/$(HOST_SUBDIR)/gcc -nostdinc++ -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src/.libs -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/libsupc++/.libs],
- c++)
-
-The -nostdinc++ flag is only used for the IN-TREE-TOOL, i.e. when using
-the just-built gcc/xgcc compiler. This means that the cross-compiler
-used to build libstdc++ will add its own libstdc++ headers to the
-include path. That results in the #include <cfenv> in
-src/c++17/floating_to_chars.cc and src/c++17/floating_from_chars.cc
-doing #include_next <fenv.h> and finding the libstdc++ fenv.h wrapper
-from the host compiler. Because that has the same include guard as the
-<fenv.h> in the libstdc++ we're trying to build, we never reach the
-underlying <fenv.h> from libc. That results in several errors of the
-form:
-
-error: 'fenv_t' has not been declared in '::'
-
-The most correct fix would be to add -nostdinc++ to the
-RAW_CXX_FOR_TARGET variable in configure.ac, or the
-RAW_CXX_TARGET_EXPORTS variable in Makefile.tpl.
-
-Another solution would be to make the libstdc++ <fenv.h> wrapper use
-_GLIBCXX_INCLUDE_NEXT_C_HEADERS like our <stdlib.h> and other C header
-wrappers.
-
-For now though, the simplest and safest solution is to just add
--nostdinc++ to the CXXFLAGS used for src/c++17/*.cc, which is what this
-does.
-
-libstdc++-v3/ChangeLog:
-
- PR libstdc++/100017
- * src/c++17/Makefile.am (AM_CXXFLAGS): Add -nostdinc++.
- * src/c++17/Makefile.in: Regenerate.

+Subject: [PATCH] configure: define TARGET_LIBC_GNUSTACK on musl
+
+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.

+ 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>

+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
