From: Kyrylo Tkachov Date: Tue, 3 Sep 2019 08:06:43 +0000 (+0000) Subject: [AArch64] Add Linux hwcap strings for some extensions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=75f935365dba3eb5e9cbd11bc0d75009cad3d019;p=gcc.git [AArch64] Add Linux hwcap strings for some extensions This patch adds feature strings for some of the extensions. This string is what is read from /proc/cpuinfo on Linux systems and used during -march=native detection. The strings are taken from the kernel source tree at: https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/cpuinfo.c#L45 * config/aarch64/aarch64-option-extensions.def (sb): Add feature string. (ssbs): Likewise. (sve2): Likewise. (sve2-sm4): Likewise. (sveaes): Likewise. (svesha3): Likewise. (svebitperm): Likewise.
