gcc : ChangeLog.tree-ssa domwalk.c domwalk.h
tree-ssa-dom.c tree-ssa.c
Log message:
* domwalk.c (walk_dominator_tree): Indicate to the block local
data initializer if the block local data is new or recycled.
* domwalk.h (struct dom_walk_data): Corresponding changes.
* tree-ssa-dom.c (dom_opt_initialize_block_local_data): Accept and use
"recycled" argument. For recycled structures, only clear varrays
that have been initialized. For new blocks, do not initialize
varrays here.
(dom_opt_finalize_block): When threading across edges, if the
true/false varrays have not been initialized, then the limit is zero.
Only clear block local varrays that have been initialized.
(record_equivalences_from_incoming_edge): If necessary, initialize
block local const_and_copies.
(dom_opt_walk_stmts): If necessary, initialize block local
stmts_to_rescan.
(record_var_is_nonzero): If necessary, initialize block local
nonzero_vars.
(record_cond_is_true): If necessary, initialize block local
true_exprs.
(record_cond_is_false): If necessary, initialize block local
false_exprs.
(lookup_avail_expr): If necessary, initialize block local
avail_exprs.
(record_range): If necessary, initialize block local vrp_varaibles.
* tree-ssa.c
* tree-ssa.c (rewrite_initialize_block_local_data): Accept and use
"recycled" argument. For recycled structures, only clear varrays
that have been initialized. For new blocks, do not initialize
varrays here.
(rewrite_finalize_block): Only clear block local varrays that have
been initialized.
(register_new_def): If necessary, initialize block local defs.
