+Subject: [PATCH 12/46] 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 13/46] 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 14/46] 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 19/46] 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 21/46] 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 22/46] 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.

+Subject: [PATCH 23/46] Disable sdt.
+
+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.

+Subject: [PATCH 24/46] 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 25/46] 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 28/46] 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.

+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.

+Subject: [PATCH 31/46] 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.

+Subject: [PATCH 37/46] 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 38/46] 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 39/46] 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.

+libssp but not libssp_nonshared something like

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

+
+Since we use -fdebug-prefix-map to do the same thing,
+so we could reuse it to replace -ffile-prefix-map.

+Subject: [PATCH 47/47] 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.

+by jsm28 (Joseph Myers)
+
+Current glibc no longer gives the ucontext_t type the tag struct
+ucontext, to conform with POSIX namespace rules. This requires
+various linux-unwind.h files in libgcc, that were previously using
+struct ucontext, to be fixed to use ucontext_t instead. This is
+similar to the removal of the struct siginfo tag from siginfo_t some
+years ago.
+
+This patch changes those files to use ucontext_t instead. As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.

+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.

+Subject: [PATCH] enable FL_LPAE flag for armv7ve cores
+
+The following commit added the FL_LPAE flag to FL_FOR_ARCH7VE, but
+neglected to also add it to the armv7ve compatible cores defined in
+arm-cores.def.
+
+ https://github.com/gcc-mirror/gcc/commit/af2d9b9e58e8be576c53d94f30c48c68146b0c98
+
+The result is that gcc 6.4 now refuses to allow -march=armv7ve and
+-mcpu=XXX to be used together, even when -mcpu is set to an armv7ve
+compatible core:
+
+ arm-linux-gnueabi-gcc -march=armv7ve -mcpu=cortex-a7 -Werror ...
+ error: switch -mcpu=cortex-a7 conflicts with -march=armv7ve switch [-Werror]
+
+Fix by defining flags for armv7ve compatible cores directly from
+FL_FOR_ARCH7VE, rather than re-creating the armv7ve flags
+independently by combining FL_FOR_ARCH7A with the armv7ve specific
+FL_THUMB_DIV and FL_ARM_DIV flags.
+

+Subject: [PATCH 01/12] i386: Move struct ix86_frame to machine_function
+
+Make ix86_frame available to i386 code generation. This is needed to
+backport the patch set of -mindirect-branch= to mitigate variant #2 of
+the speculative execution vulnerabilities on x86 processors identified
+by CVE-2017-5715, aka Spectre.
+
+ Backport from mainline
+ 2017-06-01 Bernd Edlinger <bernd.edlinger@hotmail.de>
+
+ * config/i386/i386.c (ix86_frame): Moved to ...
+ * config/i386/i386.h (ix86_frame): Here.
+ (machine_function): Add frame.
+ * config/i386/i386.c (ix86_compute_frame_layout): Repace the
+ frame argument with &cfun->machine->frame.
+ (ix86_can_use_return_insn_p): Don't pass &frame to
+ ix86_compute_frame_layout. Copy frame from cfun->machine->frame.
+ (ix86_can_eliminate): Likewise.
+ (ix86_expand_prologue): Likewise.
+ (ix86_expand_epilogue): Likewise.
+ (ix86_expand_split_stack_prologue): Likewise.

+ copy
+
+We can use const reference of struct ix86_frame to avoid making a local
+copy of ix86_frame. ix86_expand_epilogue makes a local copy of struct
+ix86_frame and uses the reg_save_offset field as a local variable. This
+patch uses a separate local variable for reg_save_offset.
+
+Tested on x86-64 with ada.

+Subject: [PATCH 04/12] x86: Add -mindirect-branch=
+
+Add -mindirect-branch= option to convert indirect call and jump to call
+and return thunks. The default is 'keep', which keeps indirect call and
+jump unmodified. 'thunk' converts indirect call and jump to call and
+return thunk. 'thunk-inline' converts indirect call and jump to inlined
+call and return thunk. 'thunk-extern' converts indirect call and jump to
+external call and return thunk provided in a separate object file. You
+can control this behavior for a specific function by using the function
+attribute indirect_branch.
+
+2 kinds of thunks are geneated. Memory thunk where the function address
+is at the top of the stack:
+
+__x86_indirect_thunk:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ lea 8(%rsp), %rsp|lea 4(%esp), %esp
+ ret
+
+Indirect jmp via memory, "jmp mem", is converted to
+
+ push memory
+ jmp __x86_indirect_thunk
+
+Indirect call via memory, "call mem", is converted to
+
+ jmp L2
+L1:
+ push [mem]
+ jmp __x86_indirect_thunk
+L2:
+ call L1
+
+Register thunk where the function address is in a register, reg:
+
+__x86_indirect_thunk_reg:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ movq %reg, (%rsp)|movl %reg, (%esp)
+ ret
+
+where reg is one of (r|e)ax, (r|e)dx, (r|e)cx, (r|e)bx, (r|e)si, (r|e)di,
+(r|e)bp, r8, r9, r10, r11, r12, r13, r14 and r15.
+
+Indirect jmp via register, "jmp reg", is converted to
+
+ jmp __x86_indirect_thunk_reg
+
+Indirect call via register, "call reg", is converted to
+
+ call __x86_indirect_thunk_reg

+Subject: [PATCH 05/12] x86: Add -mfunction-return=
+
+Add -mfunction-return= option to convert function return to call and
+return thunks. The default is 'keep', which keeps function return
+unmodified. 'thunk' converts function return to call and return thunk.
+'thunk-inline' converts function return to inlined call and return thunk.
+'thunk-extern' converts function return to external call and return
+thunk provided in a separate object file. You can control this behavior
+for a specific function by using the function attribute function_return.
+
+Function return thunk is the same as memory thunk for -mindirect-branch=
+where the return address is at the top of the stack:
+
+__x86_return_thunk:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ lea 8(%rsp), %rsp|lea 4(%esp), %esp
+ ret
+
+and function return becomes
+
+ jmp __x86_return_thunk
+
+-mindirect-branch= tests are updated with -mfunction-return=keep to
+avoid false test failures when -mfunction-return=thunk is added to
+RUNTESTFLAGS for "make check".

+Subject: [PATCH 06/12] x86: Add -mindirect-branch-register
+
+Add -mindirect-branch-register to force indirect branch via register.
+This is implemented by disabling patterns of indirect branch via memory,
+similar to TARGET_X32.
+
+-mindirect-branch= and -mfunction-return= tests are updated with
+-mno-indirect-branch-register to avoid false test failures when
+-mindirect-branch-register is added to RUNTESTFLAGS for "make check".

+
+x86-64 is supposed to have asynchronous unwind tables by default, but
+there is nothing that reflects the change in the (relative) frame
+address after .LIND0. That region really has to be moved outside of
+the .cfi_startproc/.cfi_endproc bracket.
+
+This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
+branch via register whenever -mindirect-branch= is used. Now,
+-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
+
+_Z1fP1C:
+.LFB0:
+ .cfi_startproc
+ pushq %rbx

+ popq %rbx
+ .cfi_def_cfa_offset 8
+ movq 16(%rax), %rax
+ jmp __x86_indirect_thunk_rax
+ .cfi_endproc
+
+so that "-mindirect-branch=thunk-extern" is equivalent to
+"-mindirect-branch=thunk-extern -mindirect-branch-register", which is
+used by Linux kernel.

+
+ PR c++/71696
+ * cplus-dem.c: Prevent infinite recursion when there is a cycle
+ in the referencing of remembered mangled types.
+ (work_stuff): New stack to keep track of the remembered mangled
+ types that are currently being processed.
+ (push_processed_type): New method to push currently processed
+ remembered type onto the stack.
+ (pop_processed_type): New method to pop currently processed
+ remembered type from the stack.
+ (work_stuff_copy_to_from): Copy values of new variables.
+ (delete_non_B_K_work_stuff): Free stack memory.
+ (demangle_args): Push/Pop currently processed remembered type.
+ (do_type): Do not demangle a cyclic reference and push/pop
+ referenced remembered type.
+
