Subject: [PATCH v4 5/6] selftests/x86: support header files in extra-files
Date: Wed, 16 Sep 2026 04:52:23 -0500 [thread overview]
Message-ID: <20260916095224.1533971-6-bill.roberts@arm.com> (raw)
In-Reply-To: <20260916095224.1533971-1-bill.roberts@arm.com>
The Makefile dependencies do not include header files, and adding header
files to extra-files calls will cause the header to be passed to the
compiler to compile, which is not what we want. So filter out .h files
from EXTRA_FILES but keep them for the target's prerequisites.
