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 uses 16 bytes.
Return Value:
None.
