PR tree-optimization/58775 PR tree-optimization/58791 * tree-ssa-reassoc.c (reassoc_stmt_dominates_stmt_p): New function. (insert_stmt_after): Rewritten, don't move the stmt, but really insert it. (get_stmt_uid_with_default): Remove. (build_and_add_sum): Use insert_stmt_after and reassoc_stmt_dominates_stmt_p. Fix up uid if bb contains only labels. (update_range_test): Set uid on stmts added by force_gimple_operand_gsi. Don't immediately modify statements in inter-bb optimization, just update oe->op values. (optimize_range_tests): Return bool whether any changed have been made. (update_ops): New function. (struct inter_bb_range_test_entry): New type. (maybe_optimize_range_tests): Perform statement changes here. (not_dominated_by, appears_later_in_bb, get_def_stmt, ensure_ops_are_available): Remove. (find_insert_point): Rewritten. (rewrite_expr_tree): Remove MOVED argument, add CHANGED argument, return LHS of the (new resp. old) stmt. Don't call ensure_ops_are_available, don't reuse SSA_NAMEs, recurse first instead of last, move new stmt at the right place. (linearize_expr, repropagate_negates): Don't reuse SSA_NAMEs. (negate_value): Likewise. Set uids. (break_up_subtract_bb): Initialize uids. (reassociate_bb): Adjust rewrite_expr_tree caller. (do_reassoc): Don't call renumber_gimple_stmt_uids. * gcc.dg/guality/pr58791-1.c: New test. * gcc.dg/guality/pr58791-2.c: New test. * gcc.dg/guality/pr58791-3.c: New test. * gcc.dg/guality/pr58791-4.c: New test. * gcc.dg/guality/pr58791-5.c: New test. * gcc.c-torture/compile/pr58775.c: New test. * gcc.dg/tree-ssa/reassoc-28.c: Don't scan reassoc1 dump.

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.
