-/* This file is compiled into assembly code which is then munged by a sed
-   script into two files: crti.s and crtn.s.
-
-   * crti.s puts a function prologue at the beginning of the .init and .fini
-   sections and defines global symbols for those addresses, so they can be
-   called as functions.
-
-   * crtn.s puts the corresponding function epilogues in the .init and .fini
-   sections.
-
-   This differs from what would be generated by the generic code in that
-   we save and restore the GP within the function.  In order for linker
-   relaxation to work, the value in the GP register on exit from a function
-   must be valid for the function entry point.  Normally, a function is
-   contained within one object file and this is not an issue, provided
-   that the function reloads the gp after making any function calls.
-   However, _init and _fini are constructed from pieces of many object
-   files, all of which may have different GP values.  So we must reload
-   the GP value from crti.o in crtn.o.  */
