[gdb/symtab] Handle DW_TAG_type_unit in process_psymtab_comp_unit
|
|
|
|
When running test-case gdb.cp/cpexprs-debug-types.exp with target board
|
|
unix/gdb:debug_flags=-gdwarf-5, I run into:
|
|
...
|
|
(gdb) file cpexprs-debug-types^M
|
|
Reading symbols from cpexprs-debug-types...^M
|
|
ERROR: Couldn't load cpexprs-debug-types into GDB (eof).
|
|
ERROR: Couldn't send delete breakpoints to GDB.
|
|
ERROR: GDB process no longer exists
|
|
GDB process exited with wait status 23054 exp9 0 0 CHILDKILLED SIGABRT SIGABRT
|
|
...
|
|
|
|
We're running into this abort in process_psymtab_comp_unit:
|
|
...
|
|
switch (reader.comp_unit_die->tag)
|
|
{
|
|
case DW_TAG_compile_unit:
|
|
this_cu->unit_type = DW_UT_compile;
|
|
break;
|
|
case DW_TAG_partial_unit:
|
|
this_cu->unit_type = DW_UT_partial;
|
|
break;
|
|
default:
|
|
abort ();
|
|
}
|
|
...
|
|
because reader.comp_unit_die->tag == DW_TAG_type_unit.
|
|
|
|
Fix this by adding a DW_TAG_type_unit case.
|
|
|
|
Tested on x86_64-linux.
