Subject: [PATCH 2/7] target/i386: TCG supports 3DNow! prefetch(w)
Date: Sun, 18 Jun 2023 23:51:09 +0200 [thread overview]
Message-ID: <20230618215114.107337-3-pbonzini@redhat.com> (raw)
In-Reply-To: <20230618215114.107337-1-pbonzini@redhat.com>
The AMD prefetch(w) instructions have not been deprecated together with the rest
of 3DNow!, and in fact are even supported by newer Intel processor. Mark them
as supported by TCG, as it supports all of 3DNow!.
