/*
 * this is the internal transfer function.
 *
 * HISTORY
 * 31-May-15 iOS support. Ported from arm32. Proton <feisuzhu@163.com>
 *
 * 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.
 *
