Subject: [PATCH v11 03/12] include/elf: Add defines related to GNU property notes for AArch64
Date: Fri, 16 Oct 2020 11:41:58 -0700 [thread overview]

In-Reply-To: <20201016184207.786698-1-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.
