Before IMPORTED_DECL has been introduced in PR37410, we used to emit correct DW_AT_decl_line on DW_TAG_imported_module on the testcase below, after that change we haven't emitted it at all for a while and after some time started emitting incorrect locus, in particular the location of } closing the function. The problem is that while we have correct EXPR_LOCATION on the USING_STMT, when genericizing that USING_STMT into IMPORTED_DECL we don't copy the location to DECL_SOURCE_LOCATION, so it gets whatever input_location happens to be when it is created. 2023-03-02 Jakub Jelinek <jakub@redhat.com> PR debug/108716 * cp-gimplify.cc (cp_genericize_r) <case USING_STMT>: Set DECL_SOURCE_LOCATION on IMPORTED_DECL to expression location of USING_STMT or input_location. * g++.dg/debug/dwarf2/pr108716.C: New test. |

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.
