IRA adds conflicts to the pseudos from insns can throw exceptions internally even if the exception code is final for the function and the pseudo value is not used in the exception code. This results in spilling a pseudo in a loop (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110215). The following patch fixes the problem. PR rtl-optimization/110215 gcc/ChangeLog: * ira-lives.cc: Include except.h. (process_bb_node_lives): Ignore conflicts from cleanup exceptions when the pseudo does not live at the exception landing pad. |

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.
