Subject: [PATCH v2 03/22] alpha: select ARCH_HAS_GCOV_PROFILE_ALL
Date: Sat, 05 Sep 2026 15:29:24 -0400 [thread overview]
Message-ID: <20260905-arch-kconfig-options-v2-v2-3-83e8245761a2@gmail.com> (raw)
In-Reply-To: <20260905-arch-kconfig-options-v2-v2-0-83e8245761a2@gmail.com>
GCC's gcov instrumentation (-fprofile-arcs -ftest-coverage) has no
architecture-specific runtime requirements. Enable GCOV_PROFILE_ALL
support for Alpha to allow whole-kernel code coverage analysis.
Assisted-by: Claude:claude-opus-4-6
Signed-off-by: Matt Turner <mattst88@gmail.com>
Also mark Alpha as "ok" in the gcov-profile-all feature matrix.
Tested-by: Magnus Lindholm <linmag7@gmail.com>
