(subreg_offset_representable_p): Check for and disallow cases where the modes use different numbers of bits from registers. * config/rs6000/rs6000.c (rs6000_emit_move): Handle TFmode constant for soft-float. (rs6000_hard_regno_nregs): Use UNITS_PER_FP_WORD for e500 GPRs containing doubles. (rs6000_split_multireg_move): Use DFmode reg_mode for TFmode moves in E500 double case. * config/rs6000/rs6000.md (movtf): Allow soft-float. (movtf_softfloat): New.
