4736 cross multiple loop headers. Instead invalidate the cached loop
4737 iteration information and handle case of a thread path walking
4738 into an irreducible region.

4743 * config/rs6000/rs6000.c (rs6000_split_signbit): Change some
4744 assertions. Add support for doing the signbit if the IEEE 128-bit
4745 floating point value is in a GPR.
4746 * config/rs6000/rs6000.md (Fsignbit): Delete.
4747 (signbit<mode>2_dm): Delete using <Fsignbit> and just use "wa".
4748 Update the length attribute if the value is in a GPR.
4749 (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate
4750 the sign or zero extension instruction, since the value is always 0/1.
4751 (signbit<mode>2_dm2): Delete using <Fsignbit>.
4754 * config/rs6000/vsx.md (vsx_extract_<mode>_store_p9): If we are
4755 extracting SImode to a GPR register so that we can generate a
4756 store, limit the vector to be in a traditional Altivec register
4757 for the vextuwrx instruction.
