Subject: [PATCH v3 02/13] elf.h: add aarch64 property definitions
Date: Fri, 15 May 2020 15:40:46 +0100	[thread overview]
Message-ID: <beb9c3e65e6d65c23b0e2e6825388707c063cf09.1589552054.git.szabolcs.nagy@arm.com> (raw)
In-Reply-To: <cover.1589552054.git.szabolcs.nagy@arm.com>

These property values are specified by the AArch64 ELF ABI and
binutils can create binaries marked with them.
