From 04fa17d1368c1f49801c852aac874d99ba5a6d20 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 16 Aug 2021 13:50:23 +0100 Subject: arm64/sve: Add a comment documenting the binutils needed for SVE asm At some point it would be nice to avoid the need to manually encode SVE instructions, add a note of the binutils version required to save looking it up.
