+/* 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.)
+	
+   MORAL: DO NOT MESS AROUND WITH THESE FUNCTIONS!  */
