Description

This patch adds a new Clang compiler flag "-gline-tables-only". It should reduce the amount of emitted debug information: 1) DIEs in .debug_info should only have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds), DW_TAG_lexical_block. 2) .debug_str should only contain function names 3) No debug data for types/namespaces/variables should be emitted. 4) The data in .debug_line should be enough to produce valid stack traces with function names and line numbers.

File test/CodeGen/debug-info-gline-tables-only.c (right):

test/CodeGen/debug-info-gline-tables-only.c:8: // CHECK-NOT: DW_TAG_typedef
This isn't going to work. You'll need CHECK directives around each CHECK-NOT
