I've revisited the earlier two workarounds for dwarf2out_register_external_die getting duplicate entries. It turns out that r11-525-g03d90a20a1afcb added dref_queue pruning to lto_input_tree but decl reading uses that to stream in DECL_INITIAL even when in the middle of SCC streaming. When that SCC then gets thrown away we can end up with debug nodes registered which isn't supposed to happen. The following adjusts the DECL_INITIAL streaming to go the in-SCC way, using lto_input_tree_1, since no SCCs are expected at this point, just refs. PR lto/106540 PR lto/106334 * dwarf2out.cc (dwarf2out_register_external_die): Restore original assert. * lto-streamer-in.cc (lto_read_tree_1): Use lto_input_tree_1 to input DECL_INITIAL, avoiding to commit drefs. |

README
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.
