Subject: [PATCH 06/13] arm64: gpr-num: support W registers
Date: Wed, 13 Oct 2021 12:00:52 +0100	[thread overview]
Message-ID: <20211013110059.10324-7-mark.rutland@arm.com> (raw)
In-Reply-To: <20211013110059.10324-1-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.
