Subject: [PATCH v2 12/17] [binutils/aarch64] sme: Core file support
Date: Fri, 19 May 2023 11:25:03 +0100 [thread overview]
Message-ID: <20230519102508.14020-13-luis.machado@arm.com> (raw)
In-Reply-To: <20230519102508.14020-1-luis.machado@arm.com>
From: Ezra Sitorus <ezra.sitorus@arm.com>
Add required code to support core file dumps with NT_ARM_ZA and NT_ARM_SSVE
register sets in them.
These new register sets are dumped when SME is supported.
