-From bd5e882cf6e0def3dd1bc106075d59a303fe0d1e Mon Sep 17 00:00:00 2001
-From: David Malcolm <dmalcolm@redhat.com>
-Date: Mon, 18 Oct 2021 18:55:31 -0400
-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=).
-
-gcc/c-family/ChangeLog:
- * c-lex.c (c_lex_with_flags): When complaining about non-printable
- CPP_OTHER tokens, set the "escape on output" flag.

-+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

-+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.

-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: 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.
-
-Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
-Signed-off-by: Khem Raj <raj.khem@gmail.com>
-
-RP: gcc then added *.h and *.def additions to this list, breaking the original
-fix. Add the sort to the original gcc code, leaving the tr+sort to fix the original
-issue but include the new files too as reported by Zhuang <qiuguang.zqg@alibaba-inc.com>
-
-Upstream-Status: Backport [https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=66e157188bd2f789809e17e85f917534c9381599]

+Subject: [PATCH] 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] 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.

-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).
