Subject: [PATCH v6 14/15] RISC-V: Add support for the Zvksc ISA extension
Date: Sat, 1 Jul 2023 07:21:03 +0200 [thread overview]
Message-ID: <20230701052104.4018352-15-christoph.muellner@vrull.eu> (raw)
In-Reply-To: <20230701052104.4018352-1-christoph.muellner@vrull.eu>
From: Nathan Huckleberry via Binutils <binutils@sourceware.org>
Zvksc is part of the vector crypto extensions.
Zvksc is shorthand for the following set of extensions:
- Zvks
- Zvbc
bfd/ChangeLog:
* elfxx-riscv.c: Define Zvksc extension.
gas/ChangeLog:
* testsuite/gas/riscv/zvksc.d: New test.
* testsuite/gas/riscv/zvksc.s: New test.
