Subject: [PATCH 02/12] powerpc: Add missing arch flags on rounding ifunc variants
Date: Thu, 28 Dec 2023 14:20:16 -0300 [thread overview]
Message-ID: <20231228172026.2013007-3-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20231228172026.2013007-1-adhemerval.zanella@linaro.org>
The ifunc variants now uses the powerpc implementation which in turn
uses the compiler builtin. Without the proper -mcpu switch the builtin
does not generate the expected optimization.
Checked on powerpc-linux-gnu.
