The dwarf2out map of tree to symbol + offset is populated too early when streaming in trees so that when WPA tree merging decides to recycle them the mapping prevails and if we are unlucky the same address is used for another tree with a symbol + offset DIE to record. The following mitigates the resulting ICE by relaxing the assert, allowing re-use of a slot during WPA. Delaying the register would be better but it's already somewhat hairy and uglifying this further doesn't look too important right now. PR lto/106334 * dwarf2out.cc (dwarf2out_register_external_die): Allow map entry re-use during WPA. |

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.
