|// DynASM defines used by the PPC port:
|//
|// P64 64 bit pointers (only for GPR64 testing).
|// Note: see vm_ppc64.dasc for a full PPC64 _LP64 port.
|// GPR64 64 bit registers (but possibly 32 bit pointers, e.g. PS3).
|// Affects reg saves, stack layout, carry/overflow/dot flags etc.
|// FRAME32 Use 32 bit frame layout, even with GPR64 (Xbox 360).
