This -fdebug-types-section option is a gcc option that enables the generation of a .debug_types section, which is only effective for DWARF version 4. There are two other boards that enable this: dwarf4-gdb-index and fisson, but while those test some meaningful combination of options, this board is intended to test only -fdebug-types-section. Current results with gcc 7.5.0 are: ... === gdb Summary === # of expected passes 75832 # of unexpected failures 2841 # of expected failures 130 # of known failures 75 # of unresolved testcases 22 # of untested testcases 37 # of unsupported tests 83 ... Related known issues: - PR gcc/90232 - "gcc drops top-level dies with -fdebug-types-section" - PR gdb/25875 - "segv in ada_discrete_type_low_bound" - PR gdb/14148 - "-fdebug-types-section regresses static scope of types" Tested on x86_64-linux. Committed to trunk.
