+ magic and cause the linker to emit DT_INIT and DT_FINI.
+
+ This differs from what would be generated for ordinary 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. */
