Subject: [PATCH v3 3/7] pc-bios/s390-ccw/Makefile: Use -z noexecstack to silence linker warning
Date: Thu, 29 Jun 2023 12:48:17 +0200	[thread overview]
Message-ID: <20230629104821.194859-4-thuth@redhat.com> (raw)
In-Reply-To: <20230629104821.194859-1-thuth@redhat.com>

Recent versions of ld complain when linking the s390-ccw bios:

 /usr/bin/ld: warning: start.o: missing .note.GNU-stack section implies
              executable stack
 /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in
              a future version of the linker

We can silence the warning by telling the linker to mark the stack
as not executable.
