Subject: [dpdk-dev] [PATCH] build: add -moutline-atomics to default Arm build
Date: Thu, 1 Oct 2020 08:19:54 +0200 [thread overview]
Message-ID: <1601533194-2295-1-git-send-email-juraj.linkes@pantheon.tech> (raw)
-moutline-atomics allows LSE instructions to be used if available when
compiling for ARMv8.0 instruction set. It's enabled by default on newer
compilers, such as gcc-10.1. Enable the option so that earlier compiler
versions that support it but don't enable it by default build with it.
