+Subject: [PATCH] diagnostics: escape non-ASCII source bytes for certain
+ diagnostics
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+This patch adds support to GCC's diagnostic subsystem for escaping certain
+bytes and Unicode characters when quoting source code.
+
+Specifically, this patch adds a new flag rich_location::m_escape_on_output
+which is a hint from a diagnostic that non-ASCII bytes in the pertinent
+lines of the user's source code should be escaped when printed.
+
+The patch sets this for the following diagnostics:
+- when complaining about stray bytes in the program (when these
+are non-printable)
+- when complaining about "null character(s) ignored");
+- for -Wnormalized= (and generate source ranges for such warnings)
+
+The escaping is controlled by a new option:
+ -fdiagnostics-escape-format=[unicode|bytes]
+
+For example, consider a diagnostic involing a source line containing the
+string "before" followed by the Unicode character U+03C0 ("GREEK SMALL
+LETTER PI", with UTF-8 encoding 0xCF 0x80) followed by the byte 0xBF
+(a stray UTF-8 trailing byte), followed by the string "after", where the
+diagnostic highlights the U+03C0 character.
+
+By default, this line will be printed verbatim to the user when
+reporting a diagnostic at it, as:
+
+ beforeÏXafter
+ ^
+
+(using X for the stray byte to avoid putting invalid UTF-8 in this
+commit message)
+
+If the diagnostic sets the "escape" flag, it will be printed as:
+
+ before<U+03C0><BF>after
+ ^~~~~~~~
+
+with -fdiagnostics-escape-format=unicode (the default), or as:
+
+ before<CF><80><BF>after
+ ^~~~~~~~
+
+if the user supplies -fdiagnostics-escape-format=bytes.
+
+This only affects how the source is printed; it does not affect
+how column numbers that are printed (as per -fdiagnostics-column-unit=
+and -fdiagnostics-column-origin=).

++When GCC prints pertinent source lines for a diagnostic it normally attempts
++to print the source bytes directly. However, some diagnostics relate to encoding
++issues in the source file, such as malformed UTF-8, or issues with Unicode
++normalization. These diagnostics are flagged so that GCC will escape bytes
++that are not printable ASCII when printing their pertinent source lines.
++
++This option controls how such bytes should be escaped.
++
++The default @var{FORMAT}, @samp{unicode} displays Unicode characters that
++are not printable ASCII in the form @samp{<U+XXXX>}, and bytes that do not
++correspond to a Unicode character validly-encoded in UTF-8-encoded will be
++displayed as hexadecimal in the form @samp{<XX>}.
++
++For example, a source line containing the string @samp{before} followed by the
++Unicode character U+03C0 (``GREEK SMALL LETTER PI'', with UTF-8 encoding
++0xCF 0x80) followed by the byte 0xBF (a stray UTF-8 trailing byte), followed by
++the string @samp{after} will be printed for such a diagnostic as:
++
++@smallexample
++ before<U+03C0><BF>after
++@end smallexample
++
++Setting @var{FORMAT} to @samp{bytes} will display all non-printable-ASCII bytes
++in the form @samp{<XX>}, thus showing the underlying encoding of non-ASCII
++Unicode characters. For the example above, the following will be printed:
++
++@smallexample
++ before<CF><80><BF>after
++@end smallexample

+Subject: [PATCH] libcpp: Implement -Wbidi-chars for CVE-2021-42574 [PR103026]
+
+From a link below:
+"An issue was discovered in the Bidirectional Algorithm in the Unicode
+Specification through 14.0. It permits the visual reordering of
+characters via control sequences, which can be used to craft source code
+that renders different logic than the logical ordering of tokens
+ingested by compilers and interpreters. Adversaries can leverage this to
+encode source code for compilers accepting Unicode such that targeted
+vulnerabilities are introduced invisibly to human reviewers."
+
+More info:
+https://nvd.nist.gov/vuln/detail/CVE-2021-42574
+https://trojansource.codes/
+
+This is not a compiler bug. However, to mitigate the problem, this patch
+implements -Wbidi-chars=[none|unpaired|any] to warn about possibly
+misleading Unicode bidirectional control characters the preprocessor may
+encounter.
+
+The default is =unpaired, which warns about improperly terminated
+bidirectional control characters; e.g. a LRE without its corresponding PDF.
+The level =any warns about any use of bidirectional control characters.
+
+This patch handles both UCNs and UTF-8 characters. UCNs designating
+bidi characters in identifiers are accepted since r204886. Then r217144
+enabled -fextended-identifiers by default. Extended characters in C/C++
+identifiers have been accepted since r275979. However, this patch still
+warns about mixing UTF-8 and UCN bidi characters; there seems to be no
+good reason to allow mixing them.
+
+We warn in different contexts: comments (both C and C++-style), string
+literals, character constants, and identifiers. Expectedly, UCNs are ignored
+in comments and raw string literals. The bidirectional control characters
+can nest so this patch handles that as well.
+
+I have not included nor tested this at all with Fortran (which also has
+string literals and line comments).
+
+Dave M. posted patches improving diagnostic involving Unicode characters.
+This patch does not make use of this new infrastructure yet.

++Warn about possibly misleading UTF-8 bidirectional control characters in
++comments, string literals, character constants, and identifiers. Such
++characters can change left-to-right writing direction into right-to-left
++(and vice versa), which can cause confusion between the logical order and

++of code is not commented out, whereas it in fact is.
++
++There are three levels of warning supported by GCC@. The default is
++@option{-Wbidi-chars=unpaired}, which warns about improperly terminated
++bidi contexts. @option{-Wbidi-chars=none} turns the warning off.
++@option{-Wbidi-chars=any} warns about any use of bidirectional control
++characters.

+Date: Mon, 8 Mar 2021 16:04:20 -0800
+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] libcpp: escape non-ASCII source bytes in -Wbidi-chars=
+ [PR103026]
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+This flags rich_locations associated with -Wbidi-chars= so that
+non-ASCII bytes will be escaped when printing the source lines
+(using the diagnostics support I added in
+r12-4825-gbd5e882cf6e0def3dd1bc106075d59a303fe0d1e).
+
+In particular, this ensures that the printed source lines will
+be pure ASCII, and thus the visual ordering of the characters
+will be the same as the logical ordering.

+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] libcpp: capture and underline ranges in -Wbidi-chars=
+ [PR103026]
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+This patch converts the bidi::vec to use a struct so that we can
+capture location_t values for the bidirectional control characters.
+
+Before:
+
+ Wbidi-chars-1.c: In function âmainâ:
+ Wbidi-chars-1.c:6:43: warning: unpaired UTF-8 bidirectional control character detected [-Wbidi-chars=]
+ 6 | /*<U+202E> } <U+2066>if (isAdmin)<U+2069> <U+2066> begin admins only */

+ 9 | /* end admins only <U+202E> { <U+2066>*/
+ | ^
+

+ spellings.
+ (maybe_warn_bidi_on_char): Pass in a location_t rather than a
+ const uchar * and use it when emitting warnings, and when calling
+ bidi::on_char.

+
+Use the defaults.h in ${B} instead of ${S}, and t-oe in ${B}, so that
+the source can be shared between gcc-cross-initial,
+gcc-cross-intermediate, gcc-cross, gcc-runtime, and also the sdk build.

+Upstream-Status: Pending
+
+While compiling gcc-crosssdk-initial-x86_64 on some host, there is
+occasionally failure that test the existance of default.h doesn't
+work, the reason is tm_include_list='** defaults.h' rather than
+tm_include_list='** ./defaults.h'
+
+So we add the test condition for this situation.

+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 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

+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.)

+From c55e24459370ad96577496ecd87475e3a9de7dad Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+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] 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).
+
+2021-07-20 Richard Biener <rguenther@suse.de>
+
+ PR debug/101473
+ * dwarf2out.h (dwarf_file_data): Add key member.
+ * dwarf2out.c (dwarf_file_hasher::equal): Compare key.
+ (dwarf_file_hasher::hash): Hash key.
+ (lookup_filename): Remap the filename and store it in the
+ filename member of dwarf_file_data when creating a new
+ dwarf_file_data.
+ (file_name_acquire): Do not remap the filename again.
+ (maybe_emit_file): Likewise.

+The upstream patch was modified to compensate for the definition of
+"struct dwarf_file_data" being in dwarf2out.c rather than dwarf2out.h in
