Subject: [PULL 04/37] s390x/tcg: Simplify vop64_3() handling
Date: Mon, 21 Jun 2021 11:58:09 +0200 [thread overview]
Message-ID: <20210621095842.335162-5-cohuck@redhat.com> (raw)
In-Reply-To: <20210621095842.335162-1-cohuck@redhat.com>
From: David Hildenbrand <david@redhat.com>
Let's simplify, reworking our handler generation, passing the whole "m5"
register content and not providing specialized handlers for "se", and
reading/writing proper float64 values using new helpers.
