Subject: [RISU v2 15/17] Compute reginfo_size based on the reginfo
Date: Mon, 18 May 2020 19:53:53 -0700	[thread overview]
Message-ID: <20200519025355.4420-16-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200519025355.4420-1-richard.henderson@linaro.org>

This will allow dumping of SVE frames without having
to know the SVE vector length beforehand.
