rs6000: Separate shrink-wrapping for FPRs
This patch implements separate shrink-wrapping for the non-volatile
floating point registers (FPR14..FPR31). It is pretty much exactly
analogous to the code for GPRs.
* config/rs6000/rs6000.c (struct machine_function): Add field
fpr_is_wrapped_separately.
(rs6000_get_separate_components): Use 64 components. Handle the
new FPR components.
(rs6000_components_for_bb): Handle the FPR components.
(rs6000_emit_prologue_components): Handle the FPR components.
(rs6000_emit_epilogue_components): Handle the FPR components.
(rs6000_set_handled_components): Handle the FPR components.
(rs6000_emit_prologue): Don't output prologue code for those FPRs
that are already separately shrink-wrapped.
(rs6000_emit_epilogue): Don't output epilogue code for those FPRs
that are already separately shrink-wrapped.
