[Qemu-devel] [RFC 08/12] target-ppc: Define FPR Pointer Type for Helpers

[Tom Musta]

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.
