+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.

+
+For Armv8.1-m we generate code that emits VLLDM directly and do not
+rely on support code in the library, so emit the mitigation directly
+as well, when required. In this case, we can use the compiler options
+to determine when to apply the fix and when it is safe to omit it.
+
+gcc:
+ PR target/102035
+ * config/arm/arm.md (attribute arch): Add fix_vlldm.
+ (arch_enabled): Use it.
+ * config/arm/vfp.md (lazy_store_multiple_insn): Add alternative to
+ use when erratum mitigation is needed.

+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] 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] 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>*/
+ | ^
+
+After:
+
+ Wbidi-chars-1.c: In function âmainâ:
+ Wbidi-chars-1.c:6:43: warning: unpaired UTF-8 bidirectional control characters detected [-Wbidi-chars=]
+ 6 | /*<U+202E> } <U+2066>if (isAdmin)<U+2069> <U+2066> begin admins only */
+ | ~~~~~~~~ ~~~~~~~~ ^

+ (maybe_warn_bidi_on_close): Use unpaired_bidi_rich_location when
+ reporting on unpaired bidi chars. Split into singular vs plural
+ 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.
+ (_cpp_skip_block_comment): Capture location when kind is not NONE
+ and pass it to maybe_warn_bidi_on_char.

-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.
+From: Richard Purdie <richard.purdie@linuxfoundation.org>
+Subject: [PATCH 5/5] gcc: Pass sysroot options to cpp for preprocessed source
-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.
+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 happens when ccache is in use due to the fact it uses preprocessed source files.
+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.
-The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,

-Subject: [PATCH] gcc: Fix argument list too long error.
+From: Richard Purdie <richard.purdie@linuxfoundation.org>
+Subject: [PATCH 2/5] gcc: Fix "argument list too long" from install-plugins
-There would be an "Argument list too long" error when the
-build directory is longer than 200, this is caused by:
+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.
-headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
+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.
-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.

+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=/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: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
-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.
+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:
-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.
+ * Makefile.tpl: Add CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD support

-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.

-Subject: [PATCH] arc: Update 64bit move split patterns.
-
-ARCv2HS can use a limited number of instructions to implement 64bit
-moves. The VADD2 is used as a 64bit move, the LDD/STD are 64 bit loads
-and stores. All those instructions are not baseline, hence we need to
-provide alternatives when they are not available or cannot be generate
-due to instruction restriction.
-
-This patch is cleaning up those move patterns, and updates splits
-instruction lengths.
-
-This is a backport from mainline gcc.
-
-gcc/
-2021-06-09 Claudiu Zissulescu <claziss@synopsys.com>
-
- * config/arc/arc-protos.h (arc_split_move_p): New prototype.
- * config/arc/arc.c (arc_split_move_p): New function.
- (arc_split_move): Clean up.

+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).

+[YOCTO #14481]
+
+Upstream-Status: Backport [https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=7cc2df084b7977653a9b59cbc34a9ad500ae619c]
+
+The upstream patch was modified to compensate for the definition of
+"struct dwarf_file_data" being in dwarf2out.c rather than dwarf2out.h in
+this version of gcc.
