/*
 * this is the internal transfer function.
 *
 * HISTORY
 * 14-Aug-06 File creation. Ported from Arm Thumb. Sylvain Baro
 *  3-Sep-06 Commented out saving of r1-r3 (r4 already commented out) as I
 *           read that these do not need to be saved.  Also added notes and
 *           errors related to the frame pointer. Richard Tew.
 *
 * NOTES
 *
 *   It is not possible to detect if fp is used or not, so the supplied
 *   switch function needs to support it, so that you can remove it if
 *   it does not apply to you.
 *
 * POSSIBLE ERRORS
 *
 *   "fp cannot be used in asm here"
 *
 *   - Try commenting out "fp" in REGS_TO_SAVE.
 *
