/* Vector save/restore routines for Darwin.  Note that each vector
   save/restore requires 2 instructions (8 bytes.)
 
   THE SAVE AND RESTORE ROUTINES CAN HAVE ONLY ONE GLOBALLY VISIBLE
   ENTRY POINT - callers have to jump to "saveFP+60" to save f29..f31,
   for example.  For FP reg saves/restores, it takes one instruction
   (4 bytes) to do the operation; for Vector regs, 2 instructions are
   required (8 bytes.).   */
