Re-using some common things like EQ_EXPR and other relationals made certain things easier, but complicated debugging and added extra overhead when accessing lookup tables. With forthcoming additional relation types, it makes more sense to simple have a distinct relation kind. * gimple-range-fold.cc (fold_using_range::range_of_phi): Use new VREL_* enumerated values. * gimple-range-path.cc (maybe_register_phi_relation): Ditto. * range-op.cc (*::lhs_op1_relation): Return relation_kind, and use new VREL enumerated values. (*::lhs_op2_relation): Ditto. (*::op1_op2_relation): Ditto. (*::fold_range): Use new VREL enumerated values. (minus_op1_op2_relation_effect): Ditto. (range_relational_tests): Ditto. * range-op.h (fold_range, op1_range, op2_range): Use VREL_VARYING. (lhs_op1_relation, lhs_op2_relation, op1_op2_relation): Return relation_kind. (*_op1_op2_relation): Return relation_kind. (relop_early_resolve): Use VREL_UNDEFINED. * value-query.cc (range_query::query_relation): Use VREL_VARYING. * value-relation.cc (VREL_LAST): Change enumerated value. (vrel_range_assert): Delete. (print_relation): Remove range assert. (rr_negate_table): Adjust table to use new enumerated values.. (relation_negate): Remove range assert. (rr_swap_table): Adjust. (relation_swap): Remove range assert. (rr_intersect_table): Adjust. (relation_intersect): Remove range assert. (rr_union_table): Adjust. (relation_union): Remove range assert. (rr_transitive_table): Adjust. (relation_transitive): Remove range assert. (equiv_oracle::query_relation): Use new VREL enumerated values. (equiv_oracle::register_relation): Ditto. (relation_oracle::register_stmt): Ditto. (dom_oracle::set_one_relation): Ditto. (dom_oracle::register_transitives): Ditto. (dom_oracle::query_relation): Ditto. (path_oracle::register_relation): Ditto. (path_oracle::query_relation): Ditto. * value-relation.h (enum relation_kind_t): New relation_kind. (*_op1_op2_relation): Adjust prototypes. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
