Split from: (ranger_cache::apply_inferred_ranges): Move setting cache to separate function. * gimple-range-cache.h (register_inferred_value): New prototype. * gimple-range-infer.cc (infer_range_manager::has_range_p): New. * gimple-range-infer.h (has_range_p): New prototype. * gimple-range.cc (register_transitive_inferred_ranges): New. * gimple-range.h (register_transitive_inferred_ranges): New proto. * tree-vrp.cc (rvrp_folder::fold_stmt): Check for transitive inferred ranges at the end of the block before folding final stmt. gcc/testsuite/ * gcc.dg/pr104530.c: New.
