From 8254c3d2c94ae5458095ea6c25446ba89134b9da Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christoph=20M=C3=BCllner?= Date: Fri, 1 Jul 2022 05:21:01 +0200 Subject: [PATCH] RISC-V: Add T-Head Bitmanip vendor extension MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit T-Head has a range of vendor-specific instructions. Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the XThead{Ba,Bb,Bs} extensions, a collection of T-Head-specific bitmanipulation instructions. The 'th' prefix and the "XThead{Ba,Bb,Bs}" extension are documented in a PR for the RISC-V toolchain conventions ([1]).
