From c13fd1b8fd8eef009370a629bd2ca2bbdb2f828d Mon Sep 17 00:00:00 2001 From: Aldy Hernandez Date: Mon, 14 Mar 2022 09:57:48 +0100 Subject: [PATCH] Remove various deprecated methods in class irange. This patch cleans up some irange methods in preparation for other cleanups later in the cycle. First, we prefer the reference overloads for union and intersect as the pointer versions have been deprecated for a couple releases. Also, I've renamed the legacy union/intersect whose only function was to provide additional verbosity for VRP into legacy_verbose_{union,intersect}. This is a temporary rename to serve as a visual reminder of which of the methods are bound for the chopping block when the legacy code gets removed later this cycle. Tested on x86-64 Linux. gcc/ChangeLog: * gimple-fold.cc (size_must_be_zero_p): Use reference instead of pointer * gimple-ssa-evrp-analyze.cc (evrp_range_analyzer::record_ranges_from_incoming_edge): Rename intersect to legacy_verbose_intersect. * ipa-cp.cc (ipcp_vr_lattice::meet_with_1): Use reference instead of pointer. * tree-ssa-dom.cc (dom_jt_simplifier::simplify): Use value_range instead of value_range_equiv. * tree-vrp.cc (extract_range_from_plus_minus_expr): Use reference instead of pointer. (find_case_label_range): Same. * value-range-equiv.cc (value_range_equiv::intersect): Rename to... (value_range_equiv::legacy_verbose_intersect): ...this. (value_range_equiv::union_): Rename to... (value_range_equiv::legacy_verbose_union_): ...this. * value-range-equiv.h (class value_range_equiv): Rename union and intersect to legacy_verbose_{intersect,union}. * value-range.cc (irange::union_): Rename to... (irange::legacy_verbose_union_): ...this. (irange::intersect): Rename to... (irange::legacy_verbose_intersect): ...this. * value-range.h (irange::union_): Rename union_ to legacy_verbose_union. (irange::intersect): Rename intersect to legacy_verbose_intersect. * vr-values.cc (vr_values::update_value_range): Same. (vr_values::extract_range_for_var_from_comparison_expr): Same. (vr_values::extract_range_from_cond_expr): Rename union_ to legacy_verbose_union. (vr_values::extract_range_from_phi_node): Same. --- gcc/gimple-fold.cc | 2 +- gcc/gimple-ssa-evrp-analyze.cc | 2 +- gcc/ipa-cp.cc | 2 +- gcc/tree-ssa-dom.cc | 2 +- gcc/tree-vrp.cc | 8 ++++---- gcc/value-range-equiv.cc | 4 ++-- gcc/value-range-equiv.h | 4 ++-- gcc/value-range.cc | 4 ++-- gcc/value-range.h | 8 ++++---- gcc/vr-values.cc | 12 ++++++------ 10 files changed, 24 insertions(+), 24 deletions(-) diff --git a/gcc/gimple-fold.cc b/gcc/gimple-fold.cc index 863ee3d..7baec11 100644 --- a/gcc/gimple-fold.cc +++ b/gcc/gimple-fold.cc @@ -883,7 +883,7 @@ size_must_be_zero_p (tree size) get_global_range_query ()->range_of_expr (vr, size);
