Subject: [kvm-unit-tests PATCH 2/2] Link with "-z noexecstack" to avoid warning from newer versions of ld
Date: Fri, 23 Jun 2023 14:54:16 +0200 [thread overview]
Message-ID: <20230623125416.481755-3-thuth@redhat.com> (raw)
In-Reply-To: <20230623125416.481755-1-thuth@redhat.com>
Newer versions of ld (from binutils 2.40) complain on s390x and x86:
ld: warning: s390x/cpu.o: missing .note.GNU-stack section implies
executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a
future version of the linker
We can silence these warnings by using "-z noexecstack" for linking
(which should not have any real influence on the kvm-unit-tests since
the information from the ELF header is not used here anyway, so it's
just cosmetics).
