4013
4014         * tree-ssa-dom.c (struct edge_info): New structure holding
4015         edge equivalences and edge redirection information.
4016         (get_eq_expr_value, record_dominating_conditions): Kill.
4017         (propagate_to_outgoing_edges): Renamed from cprop_into_phis.
4018         Call record_edge_info.
4019         (allocate_edge_info, free_edge_info): New.
4020         (tree_ssa_dominator_optimize): Use propagate_to_outgoing_edges
4021         rather than cprop_into_phis.  Free all edge infos before threading
4022         jumps.
4023         (thread_across_edge): Allocate new edge info structures as needed
4024         and store the redirection target into the edge info structure
4025         instead of the edge's AUX field.
4026         (dom_opt_initialize_block): Mark unused argument with ATTRIBUTE_UNUSED.
4027         (record_equivalence_from_incoming_edge): Lose unnecessary argument.
4028         Revamp code which finds and records equivalences associated with
4029         edges to use saved data in the edge_info structure.
4030         (record_equivalencs_from_phis): Similarly.
4031         (dom_opt_finalize_block): Revamp code which finds and records
4032         equivalences associated with edges to use saved data in the
4033         edge_info structure.
4034         (build_and_record_new_cond): New function.
4035         (record_conditions): Use build_and_record_new_cond to record
4036         dominating conditions.
4037         (record_edge_info): New function.
4038         (record_range): Tighten test for conditions which create
4039         useful range records.

4046         (SUBTARGET_EXTRA_SPECS): Add darwin_subarch spec.
4047         * config/darwin.h (LINK_COMMAND_SPEC): Don't pass -arch here.
4048         (LINK_SPEC): Do pass -arch here.  Handle -force_cpusubtype_ALL
4049         in all cases.  Pass the right -arch or -arch_only based on -mcpu.
4050         (ASM_SPEC): Handle -force_cpusubtype_ALL.
4051         * doc/invoke.texi (Darwin Options): Improve documentation for
