Subject: [kvm-unit-tests PULL 2/4] s390x: Remove .note.gnu.build-id section from the ELF files
Date: Tue, 26 Jun 2018 10:01:17 +0000 [thread overview]
Message-ID: <1530007279-26545-3-git-send-email-thuth@redhat.com> (raw)
While debugging another problem, we noticed that the low memory contains
some bytes which should not be there. Looks like the linker puts the
".note.gnu.build-id" section to address 0 if it has not explicitly
specified in the linker script. ARM and powerpc unit tests are apparently
already using --build-id=none to avoid this problem, so let's simply use
this linker flag in the s390x builds, too.
