Subject: [Qemu-devel] [PULL SUBSYSTEM s390x 1/3] tests/tcg/s390x: Fix alignment of csst parameter list
Date: Fri, 21 Jun 2019 15:43:36 +0200 [thread overview]
Message-ID: <20190621134338.8425-2-david@redhat.com> (raw)
In-Reply-To: <20190621134338.8425-1-david@redhat.com>
From: Richard Henderson <richard.henderson@linaro.org>
The parameter list given in general register 1 shall be aligned
on a quadword boundary. This test currently succeeds or fails
depending on the compiler version used and the accidential layout
of the function's stack frame.
