Subject: [PATCH 00/16] fix some perf issues detected by ASan
Date: Sat, 16 Mar 2019 16:05:40 +0800 [thread overview]
Message-ID: <20190316080556.3075-1-changbin.du@gmail.com> (raw)
AddressSanitizer (or ASan) and UndefinedBehaviorSanitizer (or UBSan) are
very useful tools to detect program bugs. This series fixed some issues
disclosed by ASan.
AddressSanitizer (or ASan) is a GCC feature that detects memory corruption bugs
such as buffer overflows or memory leaks.
$ cd tools/perf
$ make DEBUG=1 EXTRA_CFLAGS='-fno-omit-frame-pointer -fsanitize=address'
$ ASAN_OPTIONS=log_path=asan.log ./perf record -a
ASan outputs all detected issues into log file 'asan.log.<pid>'.
Note that this only fixes parts of the detected issues. There are many remaining
to be fixed[1].
