16591 * config/rs6000/rs6000.c (rs6000_split_signbit): Change some
16592 assertions. Add support for doing the signbit if the IEEE 128-bit
16593 floating point value is in a GPR.

16596 Update the length attribute if the value is in a GPR.
16597 (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate
16598 the sign or zero extension instruction, since the value is always 0/1.

16602 * config/rs6000/vsx.md (vsx_extract_<mode>_store_p9): If we are

16604 store, limit the vector to be in a traditional Altivec register
16605 for the vextuwrx instruction.
