[PATCH] avail_expr_stack is no longer file scoped
PR tree-optimization/47679
* tree-ssa-dom.c (avail_exprs_stack): No longer file scoped. Move
it here ...
(dom_opt_dom_walker): New private member holding the avail_exprs_stack
object. Update constructor.
(pass_dominator::execute): Corresponding chagnes to declaration
and initialization of avail_exprs_stack. Update constructor call
for dom_opt_dom_walker object.
(lookup_avail_expr, record_cond): Accept additional argument. Pass
it down to children as needed.
(record_equivalences_from_incoming_edge): Likewise.
(eliminate_redundant_computations): Likewise.
(record_equivalences_from_stmt): Likewise.
(simplify_stmt_for_jump_threading): Likewise.
(record_temporary_equivalences): Likewise.
(optimize_stmt): Likewise.
(dom_opt_dom_walker::thread_across_edge): Update access to
avail_exprs_stack object and pass it to children as needed.
(dom_opt_dom_walker::before_dom_children): Similarly.
(dom_opt_dom_walker::after_dom_children): Similarly.
* tree-ssa-threadedge.c (pfn_simplify): New typedef.
(record_temporary_equivalences_from_stmts_at_dest): Use new typedef.
Add avail_expr_stack argument. Pass it to children as needed.
(dummy_simplify): Likewise.
(simplify_control_stmt_condition): Likewise.
(thread_around_empty_blocks): Likewise.
(thread_through_normal_block): Likewise.
(thread_across_edge): Likewise.
* tree-ssa-threadedge.h (thread_across_edge): Update prototype.
* tree-vrp.c (simplify_stmt_for_jump_threading): Update.
