Subject: [PATCH v2 06/13] arm64: gpr-num: support W registers
Date: Tue, 19 Oct 2021 17:02:12 +0100 [thread overview]
Message-ID: <20211019160219.5202-7-mark.rutland@arm.com> (raw)
In-Reply-To: <20211019160219.5202-1-mark.rutland@arm.com>
In subsequent patches we'll want to map W registers to their register
numbers. Update gpr-num.h so that we can do this.
