// Test that we don't regress on the size of the line info section. We used
// to handle negative line diffs incorrectly which manifested as very
// large integers being passed to DW_LNS_advance_line.

// FIXME: This size is the same as gnu as, but we can probably do a bit better.
// FIXME2: We need a debug_line dumper so that we can test the actual contents.
