Build: Add option to restrict sanitization by architecture (cd25740c) · Commits · e / os / android_build

Add Make variable SANITIZE_ARCH to selectively sanitize binaries. This uses the "bitness," i.e., 32 or 64, to potentially filter the sanitization. By default, both are being sanitized. This can be used to create builds that lower the sanitization burden by not sanitizing "half" of the platform.
