This is the ChangeLog entry I checked in.

* config/rs6000/rs6000.md (movdi_internal32): Change constraints
so that DImode can be allocated to FP/vector registers in more
cases, and we can avoid direct move operations. If the register
needs reloading, prefer GPRs over FP/vector registers. In the
case of FPR vs. Altivec registers, prefer FPR registers unless we
have the ISA 3.0 reg+offset scalar instructions.
(movdi_internal64): Likewise.
