PR tree-optimization/83383
* gimple-ssa-evrp-analyze.h (class evrp_range_analyzer): Make
push_value_range a public interface. Add new argument to
record_ranges_from_stmt.
* gimple-ssa-evrp-analyze.c
(evrp_range_analyzer::record_ranges_from_stmt): Add new argument.
Update comments. Handle recording temporary equivalences.
* tree-ssa-dom.c (dom_opt_opt_walker::before_dom_children): Add
new argument to call to evrp_range_analyzer::record_ranges_from_stmt.
* gimple-ssa-evrp.c (evrp_dom_walker::before_dom_children): Likewise.
* tree-ssa-threadedge.c: Include alloc-pool.h, vr-values.h and
gimple-ssa-evrp-analyze.h.
(record_temporary_equivalences_from_phis): Add new argument. When
the PHI arg is an SSA_NAME, set the result's range to the range
of the PHI arg.
(record_temporary_equivalences_from_stmts_at_dest): Record ranges
from statements too.
(thread_through_normal_block): Accept new argument, evrp_range_analyzer.
Pass it down to children as needed.
(thread_outgoing_edges): Likewise.
(thread_across_edge): Likewise. Push/pop range state as needed.
* tree-ssa-threadedge.h (thread_outgoing_edges): Update prototype.
