Subject: [PATCH 0/4] pc-bios/s390-ccw: Allow building with Clang, too
Date: Sun, 2 May 2021 19:48:32 +0200 [thread overview]
Message-ID: <20210502174836.838816-1-thuth@redhat.com> (raw)
Clang can provide some additional warnings compared to GCC which can
sometimes help to catch some more bugs. So it would be good to be
able to build the s390-ccw bios with Clang, too. Only caveat: Clang
does not support the z900 anymore which is the lowest guest CPU that
could be used in QEMU, so when compiling the firmware with Clang,
it is only possible to use guest CPUs >= z10. Since the additional
compiler test coverage is worth the effort, allow it anyway and just
emit a warning in the configure step.
