  17         Rewrite SPU overlay handling code.  Put overlay calls stubs in the
  18         overlays where possible.  Use a faster call stub, or optionally at
  19         compile time, a more compact stub.  Double size of _ovly_buf_table
  20         so that low bit of _ovly_table.buf can be used as a "present" bit.
  21         Reserve an extra _ovly_table entry for index zero.
  22         * elf32-spu.c: (struct spu_link_hash_table): Delete a number of fields,
  23         add new ones.

  30         Instead set ovl_buf number in spu elf section data.  Error if
  31         overlays in one region don't start at the same address.  Adjust
  32         for struct _spu_elf_section_data changes.
