perf docs: Document building with Clang

2025-10-06T19:49:25Z

Add example commands for building perf with Clang. Since recent Android NDK releases use Clang as the default compiler, a separate Android specific document is no longer needed; point to the general build documentation instead.

perf docs: Document cross compilation

2024-07-26T18:15:55Z

Records the commands for cross compilation with two methods. The first method relies on Multiarch. The second approach is to explicitly specify the PKG_CONFIG variables, which is widely used in build system (like Buildroot, Yocto, etc).

perf tools: Add doc about how to build perf with Asan and UBSan

2019-03-19T19:52:04Z

AddressSanitizer (or ASan) and UndefinedBehaviorSanitizer (or UBSan) are very useful tools to detect program bugs: - AddressSanitizer (or ASan) is a GCC feature that detects memory corruption bugs such as buffer overflows and memory leaks. - UndefinedBehaviorSanitizer (or UBSan) is a fast undefined behavior detector supported by GCC. UBSan detects undefined behaviors of programs at runtime. This patch adds a document about how to use them on perf. Later patches will fix some of the issues disclosed by them.
