File gdb-fix-toplevel-types-with-fdebug-types-section.patch of Package gdb
gdb: Fix toplevel types with -fdebug-types-section When debugging a program compiled with -fdebug-types-section, only the first top-level type in each file is visible to gdb. The problem was caused by moving the assignment to list_in_scope from process_full_comp_unit and process_full_type_unit to start_symtab. This was fine for process_full_comp_unit, because symtabs and comp units are one-to-one. But there can be many type units per symtab (one for each type), and we only call start_symtab for the first one. This adds the necessary assignments on the paths where start_symtab is not called. gdb/Changelog: 2020-04-28 Mark Williams <mark@myosotissp.com> PR gdb/24480 * dwarf2read.c: Add missing assingments to list_in_scope when start_symtab was already called. gdb/testsuite/Changelog: 2020-04-28 Mark Williams <mark@myosotissp.com> PR gdb/24480 * dw4-toplevel-types.exp: Test for top level types. * dw4-toplevel-types.cc: Test for top level types. --- gdb/dwarf2read.c | 2 ++ gdb/testsuite/gdb.dwarf2/dw4-toplevel-types.cc | 21 +++++++++++++++ gdb/testsuite/gdb.dwarf2/dw4-toplevel-types.exp | 36 +++++++++++++++++++++++++ 3 files changed, 59 insertions(+) diff --git a/gdb/dwarf2read.c b/gdb/dwarf2read.c index 4251ed03b46..7e6f1a0ff62 100644 --- a/gdb/dwarf2read.c +++ b/gdb/dwarf2read.c @@ -11666,6 +11666,7 @@ dwarf2_cu::setup_type_unit_groups (struct die_info *die) COMPUNIT_DIRNAME (cust), compunit_language (cust), 0, cust)); + list_in_scope = get_builder ()->get_file_symbols (); } return; } @@ -11717,6 +11718,7 @@ dwarf2_cu::setup_type_unit_groups (struct die_info *die) COMPUNIT_DIRNAME (cust), compunit_language (cust), 0, cust)); + list_in_scope = get_builder ()->get_file_symbols (); for (i = 0; i < line_header->file_names.size (); ++i) { diff --git a/gdb/testsuite/gdb.dwarf2/dw4-toplevel-types.cc b/gdb/testsuite/gdb.dwarf2/dw4-toplevel-types.cc new file mode 100644 index 00000000000..c47598c46ef --- /dev/null +++ b/gdb/testsuite/gdb.dwarf2/dw4-toplevel-types.cc @@ -0,0 +1,21 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2020 Free Software Foundation, Inc. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
