      The compiler RTS should not contain assembly code routines that contain instructions listed in erratum 752770, yet one of these instructions is present in __TI_Install_CoreRegs, defined in tdeh_uwentry_t2.asm.  This is part of TDEH unwinding.  The instruction to restore R13 using an indirect load should be rewritten to match what is done in tdeh_uwentry16.asm (that is, load to an intermediate register and move the value to R13).

      Customers may run into this problem only when code is linked with exception handling enabled.
