Subject: [PATCH 01/16] perf: add doc for how to build perf with Asan and UBSan
Date: Sat, 16 Mar 2019 16:05:41 +0800 [thread overview]
Message-ID: <20190316080556.3075-2-changbin.du@gmail.com> (raw)
In-Reply-To: <20190316080556.3075-1-changbin.du@gmail.com>
AddressSanitizer (or ASan) and UndefinedBehaviorSanitizer (or UBSan) are
very useful tools to detect program bugs.
o AddressSanitizer (or ASan) is a GCC feature that detects memory
corruption bugs such as buffer overflows or memory leaks.
o UndefinedBehaviorSanitizer (or UBSan) is a fast undefined behavior
detector supprted by GCC. UBSan detect undefined behavior of programs
at runtime.
This patch adds doc for how to use them on perf. Later patches will fix
some of the issues disclosed by them.
