2015-09-18 Richard Biener <rguenther@suse.de> PR tree-optimization/66142 * fold-const.c (operand_equal_p): When OEP_ADDRESS_OF treat MEM[&x] and x the same. * tree-ssa-sccvn.h (vn_reference_fold_indirect): Remove. * tree-ssa-sccvn.c (vn_reference_fold_indirect): Return true when we simplified sth. (vn_reference_maybe_forwprop_address): Likewise. (valueize_refs_1): When we simplified through vn_reference_fold_indirect or vn_reference_maybe_forwprop_address set valueized_anything to true. (vn_reference_lookup_3): Use stmt_kills_ref_p to see whether one ref kills the other instead of just a offset-based test. * tree-ssa-alias.c (stmt_kills_ref_p): Use OEP_ADDRESS_OF for the operand_equal_p test to compare bases and also compare sizes.

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.
