3 * cfgexpand (n_stack_vars_conflict): New static variable.
4 (triangular_index): Reduce likelyhood of overflow by performing
5 the division before the multiplication.
6 (resize_stack_vars_conflict): Call fatal_error if overflow
7 occurred in triangular_index. Update n_stack_vars_conflict.
10 * regrename.c (struct du_chain): Remove member earlyclobber.
11 (scan_rtx_reg): Don't set it. Remove argument earlyclobber,
13 (scan_rtx): Remove argument earlyclobber, all callers changed.
14 (hide_operands, restore_operands, record_out_operands): New functions,
15 broken out of build_def_use.
16 (build_def_use): Call them as necessary.
18 * regrename.c (struct du_head): New members id, conflicts,
19 hard_conflicts and cannot_rename.
20 (enum scan_actions): Remove terminate_all_read and
21 terminate_overlapping_read; add mark_all_read.
22 (scan_actions_name): Likewise.
23 (du_head_p): New typedef. Define a vector type for it.

28 Remove argument B, all callers changed.
29 (regrename_optimize): Allocate id_to_chain. Ignore chains that have
30 the cannot_rename bit set. Update regno and nregs of a renamed chain.
31 Call free_chain_data when done.
32 (do_replace): Remove death notes when the renamed reg is set in the
33 last insn; add them if not.
34 (mark_conflict, note_sets_clobbers): New static function.
35 (fail_current_block, current_id, open_chains_set, live_hard_regs): New
37 (scan_rtx_reg): Keep track of conflicts between chains, and between
38 chains and hard regs. Don't terminate chains when we find a read we
39 can't handle, mark it unrenameable instead. For terminate_write,
40 terminate chains that are written with an exact match or a superset
41 of registers. Set fail_current_block if multi-word lifetimes are too
43 (scan_rtx_address): Use mark_all_read instead of terminate_all_read.
44 (build_def_use): Initialize current_id, live_chains and live_hard_regs;
45 free memory for them when done.
46 Rearrange the steps so that earlyclobbers are noted before reads
47 are processed. Add new steps to keep track of hard register lifetimes
48 outside insn operands.
