3279 GCC to return the address of large strutcures, so it should not be
3280 corrupted here. This does mean however, that this PLT does not conform
3281 to the SH PIC ABI. That spec says that r0 contains the type of the PLT
3282 and r2 contains the GOT id. This version stores the GOT id in r0 and
3283 ignores the type. Loaders can easily detect this difference however,
