Confusion in binding_cluster::maybe_get_compound_binding about whether offsets are relative to the start of the region or to the start of the cluster was leading to incorrect handling of default values, leading to false positives from -Wanalyzer-use-of-uninitialized-value, from -Wanalyzer-exposure-through-uninit-copy, and other logic errors. Fixed thusly. gcc/analyzer/ChangeLog: PR analyzer/112969 * store.cc (binding_cluster::maybe_get_compound_binding): When populating default_map, express the bit-range of the default key for REG relative to REG, rather than to the base region. gcc/testsuite/ChangeLog: PR analyzer/112969 * c-c++-common/analyzer/compound-assignment-5.c (test_3): Remove xfails, reorder tests. * c-c++-common/analyzer/compound-assignment-pr112969.c: New test. * gcc.dg/plugin/infoleak-pr112969.c: New test. * gcc.dg/plugin/plugin.exp: Add infoleak-pr112969.c to analyzer_kernel_plugin.c tests.

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.
