+/* 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. */
