[Qemu-devel] [PATCH v7 4/6] include/elf: Add defines related to GNU prop


From: Richard Henderson
Subject: [Qemu-devel] [PATCH v7 4/6] include/elf: Add defines related to GNU property notes for AArch64
Date: Sat, 3 Aug 2019 14:08:01 -0700

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.
