[sanitizer_symbolizer] Cast arguments for format strings in markup (#89815) When compiling the common sanitizer libraries, there are many warnings about format specifiers, similar to: compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_markup.cpp:31:32: warning: format specifies type 'void *' but the argument has type 'uptr' (aka 'unsigned long') [-Wformat] 31 | buffer->AppendF(kFormatData, DI->start); | ~~~~~~~~~~~ ^~~~~~~~~ compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_markup_constants.h:33:46: note: format string is defined here 33 | constexpr const char *kFormatData = "{{{data:%p}}}"; | ^~ | %lu compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_markup.cpp:46:43: warning: format specifies type 'void *' but the argument has type 'uptr' (aka 'unsigned long') [-Wformat] 46 | buffer->AppendF(kFormatFrame, frame_no, address); | ~~~~~~~~~~~~ ^~~~~~~ compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_markup_constants.h:36:48: note: format string is defined here 36 | constexpr const char *kFormatFrame = "{{{bt:%u:%p}}}"; | ^~ | %lu ... This is because `uptr` is dependent on the platform, and can be either `unsigned long long`, `unsigned long`, or `unsigned int`. To fix the warnings, cast the arguments to the expected type of the format strings. PR: 276104 Reported by: pstef MFC after: 3 days |
