Subject: [Qemu-devel] [RFC 08/12] target-ppc: Define FPR Pointer Type for Helpers
Date: Thu, 13 Mar 2014 10:13:04 -0500 [thread overview]
Message-ID: <1394723588-6072-9-git-send-email-tommusta@gmail.com> (raw)
In-Reply-To: <1394723588-6072-1-git-send-email-tommusta@gmail.com>
This patch defines a floating pointer register pointer type in the
PowerPC helper header. The type will be used to pass FPR register
operands to Decimal Floating Point (DFP) helpers. A pointer is
used because the quadword forms of PowerPC DFP instructions operate
on adjacent pairs of floating point registers and thus can be thought
of as arrays of length 2.
