Hello, In a recent review for one of the hwasan patches Richard S. noticed there are quite a few errors of the form "%<someflag%> is incompatible with <otherflag%>". https://gcc.gnu.org/pipermail/gcc-patches/2020-October/556137.html In order to avoid this creating extra work for translators we would like to change these error messages to use the form "%qs is incompatible with %qs" and pass the flag as format arguments. This patch implements that change. There is only one change in the output the compiler produces from this patch, an error message of "-fsanitize=address and -fsanitize=kernel-address are incompatible with -fsanitize=thread" has been changed to "-fsanitize=thread is incompatible with -fsanitize=address|kernel-address". This matches the similar error messages for live patching which use the messages "-f<something> is incompatible with -flive-patching=inline-only-static|inline-clone". Ok for trunk? gcc/ChangeLog: * opts.c (control_options_for_live_patching): Reform 'is incompatible with' error messages to use a standard message with differing format arguments. (finish_options): Likewise. gcc/testsuite/ChangeLog: * c-c++-common/ubsan/sanitize-recover-7.c: Update testcase.
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.
