PR tree-optimization/71437 * tree-ssa-dom.c (pfn_simplify): Add basic_block argument. All callers changed. (simplify_stmt_for_jump_threading): Add basic_block argument. All callers changed. (lhs_of_dominating_assert): Moved from here into tree-vrp.c. (dom_opt_dom_walker::thread_across_edge): Remove handle_dominating_asserts argument. All callers changed. (record_temporary_equivalences_from_stmts_at_dest): Corresponding changes. Remove calls to lhs_of_dominating_assert. Other uses of handle_dominating_asserts turn into unconditional code (simplify_control_stmt_condition_1): Likewise. (simplify_control_stmt_condition): Likewise. (thread_through_normal_block, thread_across_edge): Likewise. * tree-ssa-threadedge.h (thread_across_edge): Corresponding changes. * tree-vrp.c (lhs_of_dominating_assert): Move here. Return original object if it is not an SSA_NAME. (simplify_stmt_for_jump_threading): Call lhs_of_dominating_assert before calling into the VRP specific simplifiers. (identify_jump_threads): Remove handle_dominating_asserts argument. From-SVN: r246207
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.
