This fixes some issues with macro maps. We were incorrectly calculating the number of macro expansions in a location span, and I had a workaround that partially covered that up. Further, while macro location spans are monotonic, that is not true of ordinary location spans. Thus we need to insert an indirection array when binary searching the latter. (We load ordinary locations before loading imports, but macro locations afterwards. We make sure an import location is de-macrofied, if needed.) PR c++/98718 gcc/cp/ * module.cc (ool): New indirection vector. (loc_spans::maybe_propagate): Location is not optional. (loc_spans::open): Likewise. Assert monotonically advancing. (module_for_ordinary_loc): Use ool indirection vector. (module_state::write_prepare_maps): Do not count empty macro expansions. Elide empty spans. (module_state::write_macro_maps): Skip empty expansions. (ool_cmp): New qsort comparator. (module_state::write): Create and destroy ool vector. (name_pending_imports): Fix dump push/pop. (preprocess_module): Likewise. Add more dumping. (preprocessed_module): Likewise. libcpp/ * include/line-map.h * line-map.c gcc/testsuite/ * g++.dg/modules/pr98718_a.C: New. * g++.dg/modules/pr98718_b.C: New. |

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.
