25 /* Vector save/restore routines for Darwin. Note that each vector
26 save/restore requires 2 instructions (8 bytes.)
28 THE SAVE AND RESTORE ROUTINES CAN HAVE ONLY ONE GLOBALLY VISIBLE
29 ENTRY POINT - callers have to jump to "saveFP+60" to save f29..f31,
30 for example. For FP reg saves/restores, it takes one instruction
31 (4 bytes) to do the operation; for Vector regs, 2 instructions are
32 required (8 bytes.). */
