From 9a51da2636778dce2e2635cb10822a92a51b2b9e Mon Sep 17 00:00:00 2001 From: Jin Ma Date: Sat, 18 Nov 2023 15:07:20 +0800 Subject: RISC-V: Add fixed-point arithmetic instructions for T-Head VECTOR vendor extension MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 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 fixed-point arithmetic instructions for the "XTheadVector" extension. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([1]).
