13// Helper function used by compiler to save ppc floating point registers in
14// function prologs.  This routines also saves r0 in the LR slot.
15// If the compiler wants to save f27..f31, it does a "bl saveFP+52"
16//
17// This function should never be exported by a shared library.  Each linkage
18// unit carries its own copy of this function.
