Subject: [PATCH v2 12/22] perf test: Convert clang tests to test cases.
Date: Wed, 13 Oct 2021 10:45:54 -0700 [thread overview]
Message-ID: <20211013174604.747276-13-irogers@google.com> (raw)
In-Reply-To: <20211013174604.747276-1-irogers@google.com>
Use null terminated array of test cases rather than the previous sub
test functions.
