GCC modified for the FreeChainXenon project

The following addresses consistency check fails in copy_reference_ops_from_ref when we are handling out-of-bound array accesses (it's almost impossible to identically mimic the get_ref_base_and_extent behavior). It also addresses the case where an out-of-bound constant offset computes to a -1 off which is the special value for "unknown". This patch basically turns off verification in those cases. PR tree-optimization/113895 * tree-ssa-sccvn.cc (copy_reference_ops_from_ref): Disable consistency checking when there are out-of-bound array accesses. Allow -1 off when from an array reference with constant index. * gcc.dg/torture/pr113895-2.c: New testcase. * gcc.dg/torture/pr113895-3.c: Likewise. * gcc.dg/torture/pr113895-4.c: Likewise. |

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.
