+Subject: [PATCH] lib*: Remove i*86 march overrides
+
+OE does not pass the '--with-arch' option to gccs configure, as such
+some gcc-runtime libraries try to override the value of '-march' and
+'-mtune' which OE already provides. This causes conflicts with other
+i*86 instruction/architecture flags (e.g. -msse* and -mfpmath=*).
+Additionally this caused the following libraries to be built with less
+optimized tune configurations.
+
+Upstream suggests that this should be detecting or otherwise checking if
+the target supports the desired functionality before overriding.
+
+    https://gcc.gnu.org/legacy-ml/gcc-patches/2016-04/msg01344.html
+
+libatomic also overrides the '-march' specifically for IFUNC objects.
+OE already supplies the correct march flag, so remove setting.

+
+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] gcc-4.3.3: SYSROOT_CFLAGS_FOR_TARGET
+
+Before committing, I noticed that PR/32161 was marked as a dup of PR/32009, but my previous patch did not fix it.
+
+This alternative patch is better because it lets you just use CFLAGS_FOR_TARGET to set the compilation flags for libgcc. Since bootstrapped target libraries are never compiled with the native compiler, it makes little sense to use different flags for stage1 and later stages. And it also makes little sense to use a different variable than CFLAGS_FOR_TARGET.
+
+Other changes I had to do include:
+
+- moving the creation of default CFLAGS_FOR_TARGET from Makefile.am to configure.ac, because otherwise the BOOT_CFLAGS are substituted into CFLAGS_FOR_TARGET (which is "-O2 -g $(CFLAGS)") via $(CFLAGS). It is also cleaner this way though.
+
+- passing the right CFLAGS to configure scripts as exported environment variables
+
+I also stopped passing LIBCFLAGS to configure scripts since they are unused in the whole src tree. And I updated the documentation as H-P reminded me to do.
+
+Bootstrapped/regtested i686-pc-linux-gnu, will commit to 4.4 shortly. Ok for 4.3?

+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 and aarch64

+Subject: [PATCH] optional libstdc
+
+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.

+Subject: [PATCH] cpp: honor sysroot.
+
+Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
+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 happens when ccache is in use due to the fact it uses preprocessed source files.
+
+The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,
+-isystem, -isysroot happen and the correct sysroot is used.

+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

+Subject: [PATCH] gcc: Fix argument list too long error.
+
+There would be an "Argument list too long" error when the
+build directory is longer than 200, this is caused by:
+
+headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
+
+The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
+it, use the $(sort list) of GNU make which can handle the too long list
+would fix the problem, the header would be short enough after sorted.
+The "tr ' ' '\012'" was used for translating the space to "\n", the
+$(sort list) doesn't need this.
+

+Signed-off-by: Khem Raj <raj.khem@gmail.com>
+
+RP: gcc then added *.h and *.def additions to this list, breaking the original
+fix. Add the sort to the original gcc code, leaving the tr+sort to fix the original
+issue but include the new files too as reported by Zhuang <qiuguang.zqg@alibaba-inc.com>

+The LINK_SPEC for linux gets overwritten by linux-eabi.h which

+This patch redefines this in linux-eabi.h and reinserts it

+Subject: [PATCH] export CPP
+
+The OE environment sets and exports CPP as being the target gcc. When
+building gcc-cross-canadian for a mingw targetted sdk, the following can be found
+in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:
+
+configure:3641: checking for _FILE_OFFSET_BITS value needed for large files
+configure:3666: gcc  -c -isystem/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/include -O2 -pipe  conftest.c >&5
+configure:3666: $? = 0
+configure:3698: result: no
+configure:3786: checking how to run the C preprocessor
+configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
+configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
+configure:3876: $? = 0
+
+Note this is a *build* target (in build-x86_64-linux) so it should be
+using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
+headers are very different, using the wrong cpp is a real problem. It is leaking
+into configure through the CPP variable. Ultimately this leads to build
+failures related to not being able to include a process.h file for pem-unix.c.
+
+The fix is to ensure we export a sane CPP value into the build
+environment when using build targets. We could define a CPP_FOR_BUILD value which may be
+the version which needs to be upstreamed but for now, this fix is good enough to
+avoid the problem.

+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

+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
+
+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.)

+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] Fix various _FOR_BUILD and related variables
+
+When doing a FOR_BUILD thing, you have to override CFLAGS with
+CFLAGS_FOR_BUILD. And if you use C++, you also have to override
+CXXFLAGS with CXXFLAGS_FOR_BUILD.
+Without this, when building for mingw, you end up trying to use
+the mingw headers for a host build.
+
+The same goes for other variables as well, such as CPPFLAGS,
+CPP, and GMPINC.

+
+Prevent a segmentation fault which occurs when using incorrect
+structure trying to access name of some named operators, such as
+CPP_NOT, CPP_AND etc. "token->val.node.spelling" cannot be used in
+those cases, as is may not be initialized at all.

+
+2017-11-16  Raghunath Lolur  <raghunath.lolur@kpit.com>
+
+	* gcc.dg/pr56275.c: If SSE is disabled, ensure that

+	* gcc.target/i386/pr70467-1.c: Likewise
+	* gcc.target/i386/warn-vect-op-1.c: Likewise
+
+If -Wall, -Werror are used during compilation various test cases fail
+to compile.
+
+If SSE is disabled, be sure to -mfpmath=387 to resolve this.
+
+This patch removes the changes to Changelog from the original patch.
+This will help us avoid conflicts.

+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.
+
+gcc/Changelog:
+
+2015-05-11  Szabolcs Nagy  <szabolcs.nagy@arm.com>
+
+	* config/i386/i386-expand.c (ix86_expand_builtin): Make __builtin_cpu_init
+	call __cpu_indicator_init_local instead of __cpu_indicator_init.
