From 4e062fc955b684d004b252b33b006a6a16899f5c Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 2 Sep 2021 17:00:19 +0200 Subject: arm64: Kconfig: Enable usage of optimized memset/memcpy/memmove This patch enables the use of the optimized memset(), memmove() & memcpy() versions recently added on ARM64. Please note that these optimized functions are now only enabled for recent GCC versions (>= 9.4), as earlier GCC versions throw these errors: aarch64-linux-ar: warning: arch/arm/lib/memset-arm64.o: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0000000 ...
