It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.
