PR target/60735
* config/rs6000/rs6000.c (rs6000_hard_regno_mode_ok): If we have
software floating point or no floating point registers, do not
allow any type in the FPRs. Eliminate a test for SPE SIMD types
in GPRs that occurs after we tested for GPRs that would never be
true.
* config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64):
Rewrite tests to use TARGET_DOUBLE_FLOAT and TARGET_E500_DOUBLE,
since the FMOVE64 type is DFmode/DDmode. If TARGET_E500_DOUBLE,
specifically allow DDmode, since that does not use the SPE SIMD
instructions.

As the comment in the code already indicated DWARF2 does provide
DW_FORM_sdata/DW_FORM_udata to represent signed/unsigned data.
Enumeration constants wider than HOST_WIDE_INT are already handled
separately. Those constant values that do fit a HOST_WIDE_INT can
be encoded as signed or unsigned depending on type and value for
more efficient encoding.
* dwarf2out.c (gen_enumeration_type_die): Add DW_AT_const_value
as unsigned or int depending on type and value used.
