+Subject: [PATCH 11/47] 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 12/47] 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.

+Subject: [PATCH 13/47] 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 18/47] 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.

+Subject: [PATCH 21/47] 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.

+We don't list dtrace in DEPENDS so we shouldn't be depending on this header.
+It may or may not exist from preivous builds though. To be determinstic, disable
+sdt.h usage always. This avoids build failures if the header is removed after configure
+but before libgcc is compiled for example.

+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

+Subject: [PATCH 24/47] 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 27/47] 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 28/47] Enable SPE & AltiVec generation on powepc*linux target
+
+When is configured with --target=powerpc-linux, the resulting GCC will
+not be able to generate code for SPE targets (e500v1/v2).
+GCC configured with --target=powerpc-linuxspe will not be able to
+generate AltiVec instructions (for e6500).
+This patch modifies the configured file such that SPE or AltiVec code
+can be generated when gcc is configured with --target=powerpc-linux.
+The ABI and speciffic instructions can be selected through the
+"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.

+
+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.

+Subject: [PATCH 36/47] 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.

+Subject: [PATCH 37/47] 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 38/47] 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.

+The oe-core may use external toolchain to compile,

+
+Since we use -fdebug-prefix-map to do the same thing,

+musl does not support ldbl 128 so we can not assume

+act upon configure option passed to gcc and assume no
+on musl and yes otherwise if no option is passed since

+Subject: [PATCH] [ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing
+ with -mno-unaligned-access
+
+Peephole patterns exist in the arm backend to spot load/store
+operations to adjacent memory operations in order to convert them into
+ldrd/strd instructions. However, when we have strict alignment
+enforced, then we can only do this if the accesses are known to be
+64-bit aligned; this is unlikely to be the case for most loads. The
+patch adds some alignment checking to the code that validates the
+addresses for use in the peephole patterns. This should also fix
+incorrect generation of ldrd/strd with unaligned accesses that could
+previously have occurred on ARMv5e where all such operations must be
+64-bit aligned.
+
+I've added some new tests as well. In doing so I discovered that the
+ldrd/strd peephole tests could never fail since they would match the
+source file name in the scanned assembly as well as any instructions
+of the intended type. I've fixed those by tightening the scan results
+slightly.
+
+gcc:
+
+* config/arm/arm.c (align_ok_ldrd_strd): New function.
+(mem_ok_for_ldrd_strd): New parameter align. Extract the alignment of the
+mem into it.
+(gen_operands_ldrd_strd): Validate the alignment of the accesses.
+
+testsuite:
+
+* gcc.target/arm/peep-ldrd-1.c: Tighten test scan pattern.
+* gcc.target/arm/peep-strd-1.c: Likewise.
+* gcc.target/arm/peep-ldrd-2.c: New test.
+* gcc.target/arm/peep-strd-2.c: New test.
