In order to make this possible, this patch refactors build_type_psymtabs_reader. This change is done separately because it is easy to review in isolation and it helps make the later patches smaller. --- gdb/dwarf2/read.c | 19 +++++++------------ 1 file changed, 7 insertions(+), 12 deletions(-) diff --git a/gdb/dwarf2/read.c b/gdb/dwarf2/read.c index d9242da0ea4..464e1452d9b 100644 --- a/gdb/dwarf2/read.c +++ b/gdb/dwarf2/read.c @@ -1090,9 +1090,7 @@ static dwarf2_psymtab *create_partial_symtab (dwarf2_per_cu_data *per_cu, dwarf2_per_objfile *per_objfile, const char *name); -static void build_type_psymtabs_reader (const struct die_reader_specs *reader, - const gdb_byte *info_ptr, - struct die_info *type_unit_die); +static void build_type_psymtabs_reader (cutu_reader *reader); static void dwarf2_build_psymtabs_hard (dwarf2_per_objfile *per_objfile); @@ -7160,8 +7158,7 @@ process_psymtab_comp_unit (dwarf2_per_cu_data *this_cu, /* Nothing. */ } else if (this_cu->is_debug_types) - build_type_psymtabs_reader (&reader, reader.info_ptr, - reader.comp_unit_die); + build_type_psymtabs_reader (&reader); else if (want_partial_unit || reader.comp_unit_die->tag != DW_TAG_partial_unit) process_psymtab_comp_unit_reader (&reader, reader.info_ptr, @@ -7175,9 +7172,7 @@ process_psymtab_comp_unit (dwarf2_per_cu_data *this_cu, /* Reader function for build_type_psymtabs. */ static void -build_type_psymtabs_reader (const struct die_reader_specs *reader, - const gdb_byte *info_ptr, - struct die_info *type_unit_die) +build_type_psymtabs_reader (cutu_reader *reader) { dwarf2_per_objfile *per_objfile = reader->cu->per_objfile; struct dwarf2_cu *cu = reader->cu; @@ -7188,6 +7183,8 @@ build_type_psymtabs_reader (const struct die_reader_specs *reader, struct partial_die_info *first_die; CORE_ADDR lowpc, highpc; dwarf2_psymtab *pst; + const gdb_byte *info_ptr = reader->info_ptr; + struct die_info *type_unit_die = reader->comp_unit_die; gdb_assert (per_cu->is_debug_types); sig_type = (struct signatured_type *) per_cu; @@ -7320,8 +7317,7 @@ build_type_psymtabs (dwarf2_per_objfile *per_objfile) cutu_reader reader (tu.sig_type, per_objfile, abbrev_table.get (), nullptr, false); if (!reader.dummy_p) - build_type_psymtabs_reader (&reader, reader.info_ptr, - reader.comp_unit_die); + build_type_psymtabs_reader (&reader); } } @@ -7409,8 +7405,7 @@ process_skeletonless_type_unit (void **slot, void *info) /* This does the job that build_type_psymtabs would have done. */ cutu_reader reader (entry, per_objfile, nullptr, nullptr, false); if (!reader.dummy_p) - build_type_psymtabs_reader (&reader, reader.info_ptr, - reader.comp_unit_die); + build_type_psymtabs_reader (&reader); return 1; } -- 2.31.1
