[David Edelsohn]

2007-02-06  Roger Sayle  <roger@eyesopen.com>

        * config/rs6000/rs6000.md (popcount<mode>2): Rewrite.
        (parity<mode>2): New define_expand using rs6000_emit_parity.
        * config/rs6000/rs6000.c (rs6000_emit_popcount,
        rs6000_emit_parity): New functions.
        * config/rs6000/rs6000-protos.h (rs6000_emit_popcount,
        rs6000_emit_parity): Prototype here.

        * gcc.target/powerpc/popcount-1.c: New test case.
        * gcc.target/powerpc/parity-1.c: Likewise.

Okay.  Thanks!
