Subject: [PATCH v1 05/10] perf build: Enable additional Clang thread-safety flags
Date: Tue, 13 Oct 2026 11:24:53 -0700 [thread overview]
Message-ID: <20261013182458.1234616-6-irogers@google.com> (raw)
In-Reply-To: <20261013182458.1234616-1-irogers@google.com>
Align tools/perf's Clang thread-safety flags with the kernel's
scripts/Makefile.context-analysis by adding -Wthread-safety-pointer,
-Wthread-safety-beta, and (when supported by the compiler)
-fexperimental-late-parse-attributes.
Assisted-by: Antigravity:gemini-3.1-pro
