+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".

+From: Khem Raj <raj.khem@gmail.com>
+Date: Fri, 29 Mar 2013 09:10:06 +0400
+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 5/5] gcc: Pass sysroot options to cpp for preprocessed source
+
+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] 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.

+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

+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.)

+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

+OE passes the right options via gcc compiler cmdline via TUNE_CCARGS

+# Notes on the way the OE cross toolchain now works
+#
+# We need a libgcc to build glibc. Tranditionally we therefore built
+# a non-threaded and non-shared compiler (gcc-cross-initial), then use
+# that to build libgcc-initial which is used to build glibc which we can
+# then build gcc-cross and libgcc against.
+#
+# We were able to drop the glibc dependency from gcc-cross, with two tweaks:
+
+# a) specify the minimum glibc version to support in a configure option
+# b) create a dummy limits.h file so that later when glibc creates one,
+#    the headers structure has support for it. We can do this with a simple
+#    empty file
+#
+# Once gcc-cross is libc independent, we can use it to build both
+# libgcc-initial and then later libgcc.
+#
+# libgcc-initial is tricky as we need to imitate the non-threaded and
+# non-shared case. We can do that by hacking the threading mode back to
+# "single" even if gcc reports "posix" and disable libc presence for the
+# libgcc-intial build. We have to create the dummy limits.h to avoid
+# compiler errors from a missing header.
+#
+# glibc will fail to link with libgcc-initial due to a missing "exception
+# handler" capable libgcc (libgcc_eh.a). Since we know glibc doesn't need
+# any exception handler, we can safely symlink to libgcc.a.
