From 36029fd6b14f6d3063d8cabc834fb1ff740a32a8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Juraj=20Linke=C5=A1?= Date: Fri, 9 Oct 2020 11:50:32 +0200 Subject: [PATCH] config: add -moutline-atomics to default Arm build MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit -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 in case an earlier compiler version is used for the default build that lacks either -mcpu or -mtune which would otherwise enable it.
