Stephan Bergmann reported that our -Wbidi-chars breaks the build of LibreOffice because we warn about UCNs even when their usage is correct: LibreOffice constructs strings piecewise, as in: aText = u"\u202D" + aText; and warning about that is overzealous. Since no editor (AFAIK) interprets UCNs to show them as Unicode characters, there's less risk in misinterpreting them, and so perhaps we shouldn't warn about them by default. However, identifiers containing UCNs or programs generating other programs could still cause confusion, so I'm keeping the UCN checking. To turn it on, you just need to use -Wbidi-chars=unpaired,ucn or -Wbidi-chars=any,ucn. The implementation is done by using the new EnumSet feature. PR preprocessor/104030 gcc/c-family/ChangeLog: * c.opt (Wbidi-chars): Mark as EnumSet. Also accept =ucn. gcc/ChangeLog: * doc/invoke.texi: Update documentation for -Wbidi-chars. libcpp/ChangeLog: * include/cpplib.h (enum cpp_bidirectional_level): Add bidirectional_ucn. Set values explicitly. * internal.h (cpp_reader): Adjust warn_bidi_p. * lex.cc (maybe_warn_bidi_on_close): Don't warn about UCNs unless UCN checking is on. (maybe_warn_bidi_on_char): Likewise. gcc/testsuite/ChangeLog: * c-c++-common/Wbidi-chars-10.c: Turn on UCN checking. * c-c++-common/Wbidi-chars-11.c: Likewise. * c-c++-common/Wbidi-chars-14.c: Likewise. * c-c++-common/Wbidi-chars-16.c: Likewise. * c-c++-common/Wbidi-chars-17.c: Likewise. * c-c++-common/Wbidi-chars-4.c: Likewise. * c-c++-common/Wbidi-chars-5.c: Likewise. * c-c++-common/Wbidi-chars-6.c: Likewise. * c-c++-common/Wbidi-chars-7.c: Likewise. * c-c++-common/Wbidi-chars-8.c: Likewise. * c-c++-common/Wbidi-chars-9.c: Likewise. * c-c++-common/Wbidi-chars-ranges.c: Likewise. * c-c++-common/Wbidi-chars-18.c: New test. * c-c++-common/Wbidi-chars-19.c: New test. * c-c++-common/Wbidi-chars-20.c: New test. * c-c++-common/Wbidi-chars-21.c: New test. * c-c++-common/Wbidi-chars-22.c: New test. * c-c++-common/Wbidi-chars-23.c: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
