Subject: [PATCH v10 3/8] include/elf: Add defines related to GNU property notes for AArch64
Date: Fri,  2 Oct 2020 16:59:50 -0500	[thread overview]
Message-ID: <20201002215955.254866-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20201002215955.254866-1-richard.henderson@linaro.org>

These are all of the defines required to parse
GNU_PROPERTY_AARCH64_FEATURE_1_AND, copied from binutils.
Other missing defines related to other GNU program headers
and notes are elided for now.
