1829 GCC to return the address of large structures, so it should not be
1830 corrupted here. This does mean however, that this PLT does not conform
1831 to the SH PIC ABI. That spec says that r0 contains the type of the PLT
1832 and r2 contains the GOT id. This version stores the GOT id in r0 and
1833 ignores the type. Loaders can easily detect this difference however,
1834 since the type will always be 0 or 8, and the GOT ids will always be
