-/* entry.S - exception handler for emulating MIPS16 'entry' and 'exit'
-   pseudo-instructions.  These instructions are generated by the compiler
-   when the -mentry switch is used.  The instructions are not implemented
-   in the MIPS16 CPU; hence the exception handler that emulates them.
-
-   This module contains the following public functions:
-
-   * void __install_entry_handler(void);
-
-     This function installs the entry/exit exception handler.  It should
-     be called before executing any MIPS16 functions that were compiled with
-     -mentry, typically before main() is called.
-
-   * void __remove_entry_handler(void);
-
-     This function removes the entry/exit exception handler.  It should
-     be called when the program is exiting, or when it is known that no
-     more MIPS16 functions compiled with -mentry will be called.
