Subject: [kvm-unit-tests PATCH 2/4] powerpc: Probe whether the compiler understands -mabi=no-altivec
Date: Tue, 22 Jun 2021 15:55:15 +0200 [thread overview]
Message-ID: <20210622135517.234801-3-thuth@redhat.com> (raw)
In-Reply-To: <20210622135517.234801-1-thuth@redhat.com>
Clang does not support "-mabi=no-altivec", so let's check whether
this option is supported before using it.
