Subject: [PATCH v5 09/12] math: Add math-use-builtinds-fmin.h
Date: Tue, 7 Dec 2021 16:03:50 -0300 [thread overview]
Message-ID: <20211207190353.3282666-10-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20211207190353.3282666-1-adhemerval.zanella@linaro.org>
It allows the architecture to use the builtin instead of generic
implementation.
