[Patch,AVR]: Tweak 8-bit parity expansion

2011-10-28 Thread Georg-Johann Lay
This is minor tweak to support 8-bit parity. Otherwise, the input operand of 8-bit values will be extended before parity computation. The final representation as libgcc call is not generated in split1 and no more in expand. Notice that - combine is not allowed to propagate hard regs into zero-ex
