/* 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. */

/* If we use the standard C version, the linkage table pointer won't
   be properly preserved due to the splitting up of function prologues
   and epilogues.  Therefore we write these in assembly to make sure
   they do the right thing.

   Note that we cannot have a weak undefined __gmon_start__, because
   that would require this to be PIC, and the linker is currently not
   able to generate a proper procedure descriptor for _init.  Sad but
   true.  Anyway, HPPA is one of those horrible architectures where
   making the comparison and indirect call is quite expensive (see the
   comment in sysdeps/generic/initfini.c). */
