Subject: [PATCH 0/8] perf build: Support building with Clang
Date: Thu, 25 Sep 2025 11:26:24 +0100 [thread overview]
Message-ID: <20250925-perf_build_android_ndk-v1-0-8b35aadde3dc@arm.com> (raw)
This series adds support for building perf with Clang, following the
discussion in [1]. Because the Android NDK uses Clang by default,
enabling Clang builds naturally covers Android as well.
The series is organized as follows:
- Patches 1–2: Fix two bugs found with Clang.
- Patches 3–6: Address Clang build warnings. Because these warnings
do not break the build, no Fixes tag is added to avoid backporting.
- Patches 7–8: Enable Clang in the Makefile and update the
documentation.
Testing:
- Clang 15.0.7 on Ubuntu 22.04.5: native and cross-compiling (aarch64)
- Clang 18.1.3 on Ubuntu 24.04.2: native and cross-compiling (aarch64)
- Android NDK r27d (latest LTS): cross-compiling (aarch64)
