More changes were made\nto the LRA than the IRA since the LRA will modify the DF data directly.\nThe main big changes are centered on the lra-lives.cc file.\n\ngcc/ChangeLog:\n\n\t* lra-coalesce.cc (update_live_info): Extend to DF_LIVE_SUBREG.\n\t(lra_coalesce): Ditto.\n\t* lra-constraints.cc (update_ebb_live_info): Ditto.\n\t(get_live_on_other_edges): Ditto.\n\t(inherit_in_ebb): Ditto.\n\t(lra_inheritance): Ditto.\n\t(fix_bb_live_info): Ditto.\n\t(remove_inheritance_pseudos): Ditto.\n\t* lra-int.h (GCC_LRA_INT_H): include subreg-live-range.h\n\t(struct lra_insn_reg): Add op filed to record the corresponding rtx.\n\t* lra-lives.cc (class bb_data_pseudos): Extend the bb_data_pseudos to\n\tinclude new partial_def/use and range_def/use fileds for DF_LIVE_SUBREG\n\tproblem.\n\t(need_track_subreg_p): checking is the regno need to be tracked.\n\t(make_hard_regno_live): switch to live_subreg filed.\n\t(make_hard_regno_dead): Ditto.\n\t(mark_regno_live): Support record subreg liveness.\n\t(mark_regno_dead): Ditto.\n\t(live_trans_fun): Adjust transfer function to support subreg liveness.\n\t(live_con_fun_0): Adjust Confluence function to support subreg liveness.\n\t(live_con_fun_n): Ditto.\n\t(initiate_live_solver): Ditto.\n\t(finish_live_solver): Ditto.\n\t(process_bb_lives): Ditto.\n\t(lra_create_live_ranges_1): Dump subreg liveness.\n\t* lra-remat.cc (dump_candidates_and_remat_bb_data): Switch to\n\tDF_LIVE_SUBREG df data.\n\t(calculate_livein_cands): Ditto.\n\t(do_remat): Ditto.\n\t* lra-spills.cc (spill_pseudos): Ditto.\n\t* lra.cc (new_insn_reg): New argument op.\n\t(add_regs_to_insn_regno_info): Add new argument op.\n",
