								Routine Description:


								    On transition from ia64 mode to ia32 (and back), the f8-f15 registers

								    contain the st[0] to st[7] fp stack values. Alas, these values don't

								    map one-one, so the FSR.top bits are used to determine which ia64

								    register has the top of stack. We then need to rotate these registers

								    since ia32 context is expecting st[0] to be the first fp register (as

								    if FSR.top is zero). This routine only works on full 16-byte ia32

								    saved fp data (such as from ExtendedRegisters - the FXSAVE format).

								    Other routines can convert this into the older FNSAVE format.


								Arguments:


								    Ia64_FSR - The ia64 FSR register. Has the FSR.top needed for this routine


								    ia32FxSave - The ia32 fp stack (in FXSAVE format). Each ia32 fp register
