Subject: [PATCH 05/16] lib/test_bitmap: disable compile-time test if DEBUG_BITMAP() is enabled
Date:   Mon, 18 Jul 2022 12:28:33 -0700
Message-Id: <20220718192844.1805158-6-yury.norov@gmail.com>
In-Reply-To: <20220718192844.1805158-1-yury.norov@gmail.com>
References: <20220718192844.1805158-1-yury.norov@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

CONFIG_DEBUG_BITMAP, when enabled, injects __bitmap_check_params()
into bitmap functions. It prevents compiler from compile-time
optimizations, which makes corresponding test fail.
