--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:e9e4ddfc5abbf9ee5e657d626264cef89f10b4c3 commit r11-6270-ge9e4ddfc5abbf9ee5e657d626264cef89f10b4c3 Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Wed Dec 16 00:17:40 2020 +0100 d: Fix ICE in in force_decl_die, at dwarf2out.c with -gdwarf-2 -gstrict-dwarf [PR98067] Manifest constants in D are represented as CONST_DECLs, which can be imported from one module to another. However, when compiling on strict dwarf2 targets such as *-*-darwin10, importing CONST_DECLs cannot be represented in debug as D did not exist as an AT_language until dwarf3, and the only available fallback being DW_LANG_C. As CONST_DECLs are treated as enumerators in C, and not outputted individually in gen_decl_die, this causes an internal error in force_decl_die to occur. To handle this, similar to other places in dwarf2out, if a CONST_DECL is seen in dwarf2out_imported_module_or_decl_1, then we simply return early if the language is not one of Ada, D, or Fortran. gcc/ChangeLog: PR d/98067 * dwarf2out.c (dwarf2out_imported_module_or_decl_1): Handle CONST_DECL only if is_fortran, is_ada, or is_dlang. gcc/testsuite/ChangeLog: PR d/98067 * gdc.dg/debug/debug.exp: New test. * gdc.dg/debug/dwarf2/dwarf2.exp: New test. * gdc.dg/debug/dwarf2/imports/pr98067.d: New test. * gdc.dg/debug/dwarf2/langdw2.d: New test. * gdc.dg/debug/dwarf2/langdw3.d: New test. * gdc.dg/debug/dwarf2/pr98067.d: New test. * gdc.dg/debug/trivial.d: New test.
