--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Roman Lebedev from comment #10) > I'm not at all familiar with the GCC's preferred patch protocol, See https://gcc.gnu.org/contribute.html#patches > this is the result of `git format-patch origin/master`, That format is great. > with commit message mimicking the ones of the recent commits. > Please let me know what i got wrong this time. The commit message should be in the form "libstdc++: ..." I would just use "libstdc++: silence clang's Integer Sanitizer [PR108674]". The no_sanitize attribute needs to be __no_sanitize__ instead, because this is a valid program: #define no_sanitize !!1!1 #include <string> int main() { } Otherwise this looks reasonable. The __no_sanitize__("unsigned-integer-overflow") attribute seems to be supported by all non-ancient versions of Clang. Also, please note that the Signed-off-by: tag has the meaning described at https://gcc.gnu.org/dco.html so please be sure that's what you intend when using it :-) Please make the changes above and post to the gcc-patches list, CCing the libstdc++ list, thanks!
