Subject: re PR tree-optimization/47679 (Strange uninitialized warning after
 SRA)

	PR tree-optimization/47679
	* Makefile.in (OBJS); Add tree-ssa-scopedtables.o.
	* tree-ssa-scopedtables.c: New file.
	* tree-ssa-scopedtables.h: New file.
	* tree-ssa-dom.c: Include tree-ssa-scopedtables.h.
	(const_and_copies): Change name/type.
	(record_const_or_copy): Move into tree-ssa-scopedtables.c
	(record_const_or_copy_1): Similarly.
	(restore_vars_to_original_value): Similarly.
	(pass_dominator::execute): Create and destroy const_and_copies table.
	(thread_across_edge): Update passing of const_and_copies.
	(record_temporary_equivalence): Use method calls rather than
	manipulating const_and_copies directly.
	(record_equality, cprop_into_successor_phis): Similarly.
	(dom_opt_dom_walker::before_dom_children): Similarly.
	(dom_opt_dom_walker::after_dom_children): Similarly.
	(eliminate_redundant_computations): Similarly.
	* tree-ssa-threadedge.c (remove_temporary_equivalences): Delete.
	(record_temporary_equivalence): Likewise.
	(invalidate_equivalences): Likewise.
	(record_temporary_equivalences_from_phis): Update due to type
	change of const_and_copies.  Use method calls rather than
	manipulating the stack directly.
	(record_temporary_equivalences_from_stmts_at_dest): Likewise.
	(thread_through_normal_block, thread_across_edge): Likewise.
	(thread_across_edge): Likewise.
	* tree-ssa-threadedge.h (thread_across_edge): Update prototype.
	* tree-vrp.c: Include tree-ssa-scopedtables.h.  Change type
	of equiv_stack.
	(identify_jump_threads): Update due to type change of equiv_stack.
	(finalize_jump_threads): Delete the equiv_stack when complete.
