If DWARF contains a reference to a "dwz" file, but there is no .gnu_debugaltlink section, then gdb will crash. This happens because dwarf2_get_dwz_file will return NULL, but some callers do not expect this. This patch changes dwarf2_get_dwz_file so that callers can require a dwz file. Then, it updates the callers that are attempting to process references to the dwz file to require one. This includes a new testcase. The dwarf.exp changes don't handle the new forms exactly correctly -- they are only handled well enough to let this test case complete. gdb/ChangeLog 2021-03-06 Tom Tromey <tom@tromey.com> * dwarf2/read.h (dwarf2_get_dwz_file): Add 'require' parameter. * dwarf2/read.c (dwarf2_get_dwz_file): Add 'require' parameter. (get_abbrev_section_for_cu, read_attribute_value) (get_debug_line_section): Update. * dwarf2/macro.c (dwarf_decode_macro_bytes): Update. gdb/testsuite/ChangeLog 2021-03-06 Tom Tromey <tom@tromey.com> * lib/dwarf.exp (_handle_DW_FORM): Treat DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt like DW_FORM_sec_offset. * gdb.dwarf2/dwznolink.exp: New file. |
