Subject: [PATCH v4 2/5] math: Fix isnanf128 static build (BZ 31774)
Date: Tue, 21 May 2024 13:52:54 -0300 [thread overview]
Message-ID: <20240521165430.2998944-3-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20240521165430.2998944-1-adhemerval.zanella@linaro.org>
Some static implementation of float128 routines might call __isnanf128,
which is not provided by the static object.
Checked on x86_64-linux-gnu.
