Subject: [PATCH v3 01/15] arm: Add new tests for comparison vectorization with Neon and MVE
Date: Thu, 13 Jan 2022 15:56:11 +0100 [thread overview]
Message-ID: <20220113145645.4077141-2-christophe.lyon@foss.st.com> (raw)
In-Reply-To: <20220113145645.4077141-1-christophe.lyon@foss.st.com>
This patch mainly adds Neon tests similar to existing MVE ones,
to make sure we do not break Neon when fixing MVE.
mve-vcmp-f32-2.c is similar to mve-vcmp-f32.c but uses a conditional
with 2.0f and 3.0f constants to help scan-assembler-times.
