GCC modified for the FreeChainXenon project

The following avoids spurious uninit diagnostics for SSA name copies which mostly appear when the source is marked as abnormal which prevents copy propagation. To prevent regressions I remove the bail out for anonymous SSA names in the PHI arg place from warn_uninitialized_phi leaving that to warn_uninit where I handle SSA copies from a SSA name which isn't anonymous. In theory this might cause more valid and false positive diagnostics to pop up. PR tree-optimization/112909 * tree-ssa-uninit.cc (find_uninit_use): Look through a single level of SSA name copies with single use. * gcc.dg/uninit-pr112909.c: New testcase. |

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.
