+/* 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.). */
