+/* 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.  */
