Subject: [PATCH 10/11] allocate_once: Apply asm redirection before first use
Date: Fri, 28 Oct 2022 14:35:31 -0300 [thread overview]
Message-ID: <20221028173532.876027-11-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20221028173532.876027-1-adhemerval.zanella@linaro.org>
Compilers may not be able to apply asm redirections to functions
after these functions are used for the first time, e.g. clang 13.
