From: Alan Modra <amodra@sourceware.org> To: bfd-cvs@sourceware.org Subject: [binutils-gdb] ppc/svp64: support LibreSOC architecture Date: Thu, 11 Aug 2022 09:09:24 +0000 (GMT) [thread overview] Message-ID: <20220811090924.94681385734C@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=33ae8a3ae31d8ea787d79d2a677d960721ffe682 commit 33ae8a3ae31d8ea787d79d2a677d960721ffe682 Author: Dmitry Selyutin <ghostmansd@gmail.com> Date: Mon Jul 25 16:10:14 2022 +0300 ppc/svp64: support LibreSOC architecture This patch adds support for LibreSOC machine and SVP64 extension flag for PowerPC architecture. SV (Simple-V) is a strict RISC-paradigm Scalable Vector Extension for the Power ISA. SVP64 is the 64-bit Prefixed instruction format implementing SV. Funded by NLnet through EU Grants No: 825310 and 825322, SV is in DRAFT form and is to be publicly submitted via the OpenPOWER Foundation ISA Working Group via the newly-created External RFC Process.
