   2
   3         Rewrite SPU overlay handling code.  Put overlay calls stubs in the
   4         overlays where possible.  Use a faster call stub, or optionally at
   5         compile time, a more compact stub.  Double size of _ovly_buf_table
   6         so that low bit of _ovly_table.buf can be used as a "present" bit.
   7         Reserve an extra _ovly_table entry for index zero.
   8         * elf32-spu.c: (struct spu_link_hash_table): Delete a number of fields,
   9         add new ones.
  10         (struct got_entry): New.

  15         (spu_elf_find_overlays): Don't track sections from overlay regions.
  16         Instead set ovl_buf number in spu elf section data.  Error if
  17         overlays in one region don't start at the same address.  Adjust
  18         for struct _spu_elf_section_data changes.
