+Subject: [PATCH] gcc: poison-system-directories
+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch. The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan. If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".

+Subject: [PATCH] 64-bit multilib hack.
+
+GCC has internal multilib handling code but it assumes a very specific rigid directory
+layout. The build system implementation of multilib layout is very generic and allows
+complete customisation of the library directories.
+
+This patch is a partial solution to allow any custom directories to be passed into gcc
+and handled correctly. It forces gcc to use the base_libdir (which is the current
+directory, "."). We need to do this for each multilib that is configured as we don't
+know which compiler options may be being passed into the compiler. Since we have a compiler
+per mulitlib at this point that isn't an issue.
+
+The one problem is the target compiler is only going to work for the default multlilib at
+this point. Ideally we'd figure out which multilibs were being enabled with which paths
+and be able to patch these entries with a complete set of correct paths but this we
+don't have such code at this point. This is something the target gcc recipe should do
+and override these platform defaults in its build config.
+
+Do same for riscv64, aarch64 & arc

+Subject: [PATCH 3/5] gcc: Add --nostdlib++ option
+
+[gcc-runtime builds libstdc++ separately from gcc-cross-*. Its configure tests using g++
+will not run correctly since by default the linker will try to link against libstdc++
+which shouldn't exist yet. We need an option to disable -lstdc++
+option whilst leaving -lc, -lgcc and other automatic library dependencies added by gcc
+driver. This patch adds such an option which only disables the -lstdc++.]
+
+[A "standard" gcc build uses xgcc and hence avoids this. We should ask upstream how to
+do this officially, the likely answer is don't build libstdc++ separately.]
+
+OpenEmbedded/Yocto Project builds libgcc and the other gcc runtime libraries
+separately from the compiler and slightly differently to the standard gcc build.
+
+In general this works well but in trying to build them separately we run into
+an issue since we're using our gcc, not xgcc and there is no way to tell configure
+to use libgcc but not look for libstdc++.
+
+This adds such an option allowing such configurations to work.

+
+OpenEmbedded/Yocto Project extensively uses the --sysroot support within gcc.
+We discovered that when compiling preprocessed source (.i or .ii files), the
+compiler will try and access the builtin sysroot location rather than the
+--sysroot option specified on the commandline. If access to that directory is
+permission denied (unreadable), gcc will error. This is particularly problematic
+when ccache is involved.
+
+This patch adds %I to the cpp-output spec macro so the default substitutions for
+-iprefix, -isystem, -isysroot happen and the correct sysroot is used.

+Subject: [PATCH] Define GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
+ relative to SYSTEMLIBS_DIR
+
+This patch defines GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
+relative to SYSTEMLIBS_DIR which can be set in generated headers
+This breaks the assumption of hardcoded multilib in gcc
+Change is only for the supported architectures in OE including
+SH, sparc, alpha for possible future support (if any)
+
+Removes the do_headerfix task in metadata

+Subject: [PATCH 2/5] gcc: Fix "argument list too long" from install-plugins
+
+When building in longer build paths (200+ characters), the
+"echo $(PLUGIN_HEADERS)" from the install-plugins target would cause an
+"argument list too long error" on some systems.
+
+Avoid this by calling make's sort function on the list which removes
+duplicates and stops the overflow from reaching the echo command.
+The original sort is left to handle the the .h and .def files.

+Subject: [PATCH] libtool
+
+libstdc++ from gcc-runtime gets created with -rpath=/usr/lib/../lib for qemux86-64
+when running on am x86_64 build host.
+
+This patch stops this speading to libdir in the libstdc++.la file within libtool.
+Arguably, it shouldn't be passing this into libtool in the first place but
+for now this resolves the nastiest problems this causes.
+
+func_normal_abspath would resolve an empty path to `pwd` so we need
+to filter the zero case.

+Subject: [PATCH] gcc: armv4: pass fix-v4bx to linker to support EABI.
+
+The LINK_SPEC for linux gets overwritten by linux-eabi.h which
+means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
+the option is not passed to linker when chosing march=armv4
+This patch redefines this in linux-eabi.h and reinserts it
+for eabi defaulting toolchains.
+
+We might want to send it upstream.

+From: Richard Purdie <richard.purdie@linuxfoundation.org>
+Subject: [PATCH 1/5] Makefile.in: Ensure build CPP/CPPFLAGS is used for build targets
+
+During cross compiling, CPP is being set to the target compiler even for
+build targets. As an example, when building a cross compiler targetting
+mingw, the config.log for libiberty in
+build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log
+shows:
+
+configure:3786: checking how to run the C preprocessor
+configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32
+configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
+configure:3876: $? = 0
+
+This is libiberty being built for the build environment, not the target one
+(i.e. in build-x86_64-linux). As such it should be using the build environment's
+gcc and not the target one. In the mingw case the system headers are quite
+different leading to build failures related to not being able to include a
+process.h file for pem-unix.c.
+
+Further analysis shows the same issue occuring for CPPFLAGS too.
+
+Fix this by adding support for CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD which
+for example, avoids mixing the mingw headers for host binaries on linux
+systems.
+
+2021-10-27 Richard Purdie <richard.purdie@linuxfoundation.org>
+
+ChangeLog:
+
+ * Makefile.tpl: Add CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD support
+ * Makefile.in: Regenerate.
+ * configure: Regenerate.
+ * configure.ac: Add CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD support
+
+gcc/ChangeLog:
+
+ * configure: Regenerate.
+ * configure.ac: Use CPPFLAGS_FOR_BUILD for GMPINC

+Subject: [PATCH] Ensure target gcc headers can be included
+
+There are a few headers installed as part of the OpenEmbedded
+gcc-runtime target (omp.h, ssp/*.h). Being installed from a recipe
+built for the target architecture, these are within the target
+sysroot and not cross/nativesdk; thus they weren't able to be
+found by gcc with the existing search paths. Add support for
+picking up these headers under the sysroot supplied on the gcc
+command line in order to resolve this.
+
+Extend target gcc headers search to musl too

+From 354682ad8f71f62643dcd83f64b51b5979615a0c Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+Date: Mon, 7 Dec 2015 23:39:54 +0000
+Subject: [PATCH] handle sysroot support for nativesdk-gcc
+
+Being able to build a nativesdk gcc is useful, particularly in cases
+where the host compiler may be of an incompatible version (or a 32
+bit compiler is needed).
+
+Sadly, building nativesdk-gcc is not straight forward. We install
+nativesdk-gcc into a relocatable location and this means that its
+library locations can change. "Normal" sysroot support doesn't help
+in this case since the values of paths like "libdir" change, not just
+base root directory of the system.
+
+In order to handle this we do two things:
+
+a) Add %r into spec file markup which can be used for injected paths
+ such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
+b) Add other paths which need relocation into a .gccrelocprefix section
+ which the relocation code will notice and adjust automatically.
+
+Upstream-Status: Inappropriate
+RP 2015/7/28
+
+Extend the gccrelocprefix support to musl config too, this ensures
+that gcc will get right bits in SDK installations
+
+Signed-off-by: Khem Raj <raj.khem@gmail.com>
+
+Added PREFIXVAR and EXEC_PREFIXVAR to support runtime relocation. Without
+these as part of the gccrelocprefix the system can't do runtime relocation
+if the executable is moved. (These paths were missed in the original
+implementation.)
+

+Date: Mon, 7 Dec 2015 23:41:45 +0000
+Subject: [PATCH] Search target sysroot gcc version specific dirs with
+ multilib.
+
+We install the gcc libraries (such as crtbegin.p) into
+<sysroot><libdir>/<target-sys>/5.2.0/
+which is a default search path for GCC (aka multi_suffix in the
+code below). <target-sys> is 'machine' in gcc's terminology. We use
+these directories so that multiple gcc versions could in theory
+co-exist on target.
+
+We only want to build one gcc-cross-canadian per arch and have this work
+for all multilibs. <target-sys> can be handled by mapping the multilib
+<target-sys> to the one used by gcc-cross-canadian, e.g.
+mips64-polkmllib32-linux
+is symlinked to by mips64-poky-linux.
+
+The default gcc search path in the target sysroot for a "lib64" mutlilib
+is:
+
+<sysroot>/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/../lib64/
+<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/usr/lib32/../lib64/
+<sysroot>/lib32/
+<sysroot>/usr/lib32/
+
+which means that the lib32 crtbegin.o will be found and the lib64 ones
+will not which leads to compiler failures.
+
+This patch injects a multilib version of that path first so the lib64
+binaries can be found first. With this change the search path becomes:
+
+<sysroot>/lib32/../lib64/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/../lib64/
+<sysroot>/usr/lib32/../lib64/mips64-poky-linux/5.2.0/
+<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/usr/lib32/../lib64/
+<sysroot>/lib32/
+<sysroot>/usr/lib32/

+Subject: [PATCH] Add ssp_nonshared to link commandline for musl targets
+
+when -fstack-protector options are enabled we need to
+link with ssp_shared on musl since it does not provide
+the __stack_chk_fail_local() so essentially it provides
+libssp but not libssp_nonshared something like
+TARGET_LIBC_PROVIDES_SSP_BUT_NOT_SSP_NONSHARED
+ where-as for glibc the needed symbols
+are already present in libc_nonshared library therefore
+we do not need any library helper on glibc based systems
+but musl needs the libssp_noshared from gcc

+Subject: [PATCH] libgcc_s: Use alias for __cpu_indicator_init instead of
+ symver
+
+Adapter from
+
+https://gcc.gnu.org/ml/gcc-patches/2015-05/msg00899.html
+
+This fix was debated but hasnt been applied gcc upstream since
+they expect musl to support '@' in symbol versioning which is
+a sun/gnu versioning extention. This patch however avoids the
+need for the '@' symbols at all
+
+libgcc/Changelog:
+
+2015-05-11 Szabolcs Nagy <szabolcs.nagy@arm.com>
+
+ * config/i386/cpuinfo.c (__cpu_indicator_init_local): Add.
+ (__cpu_indicator_init@GCC_4.8.0, __cpu_model@GCC_4.8.0): Remove.
+
+ * config/i386/t-linux (HOST_LIBGCC2_CFLAGS): Remove -DUSE_ELF_SYMVER.

+
+2015-05-11 Szabolcs Nagy <szabolcs.nagy@arm.com>

+Subject: [PATCH] debug/101473 - apply debug prefix maps before checksumming DIEs
+
+The following makes sure to apply the debug prefix maps to filenames
+before checksumming DIEs to create the global symbol for the CU DIE
+used by LTO to link the late debug to the early debug. This avoids
+binary differences (in said symbol) when compiling with toolchains
+installed under a different path and that compensated with appropriate
+-fdebug-prefix-map options.
+
+The easiest and most scalable way is to record both the unmapped
+and the remapped filename in the dwarf_file_data so the remapping
+process takes place at a single point and only once (otherwise it
+creates GC garbage at each point doing that).
