Subject: [PATCH 5/7] powerpc64le: Use <gcc-macros.h> in early HWCAP check
Date: Fri, 14 Jan 2022 13:40:47 +0100 [thread overview]
Message-ID: <42e3a9aae86bfe545c24b1fe9908d64d3fdf8cb0.1642162312.git.fweimer@redhat.com> (raw)
In-Reply-To: <cover.1642162312.git.fweimer@redhat.com>
This is required so that the checks still work if $(early-cflags)
selects a different ISA level.
