/* Note - The PLT entries have been "optimised" not to use r2.  r2 is used by
   GCC to return the address of large structures, so it should not be
   corrupted here.  This does mean however, that those PLTs does not conform
   to the SH PIC ABI.  That spec says that r0 contains the type of the PLT
   and r2 contains the GOT id.  The GNU Plt version stores the GOT id in r0 and
   ignores the type.  We can easily detect this difference however,
   since the type will always be 0 or 8, and the GOT ids will always be
   greater than or equal to 12.

   Found in binutils/bfd/elf32-sh.c by Stefan Allius <allius@atecom.com>

   Note2 - we also have to preserve r2 on the stack as the call into
   C code (_dl_linux_resolver) will use r2 as a scratch register and we
   need it for the address for returning structures,
