Subject: [RFC v13 65/80] target/arm: arch_dump: restrict ELFCLASS64 to AArch64
Date: Wed, 14 Apr 2021 13:26:35 +0200	[thread overview]
Message-ID: <20210414112650.18003-66-cfontana@suse.de> (raw)
In-Reply-To: <20210414112650.18003-1-cfontana@suse.de>

this will allow us to restrict more code to TARGET_AARCH64
