// This test should be replaced with one in tests/debuginfo once we can easily | ||
// tell via GDB or LLDB if debuginfo contains source code. Cheap tricks in LLDB | ||
// like setting an invalid source map path don't appear to work, maybe this'll | ||
// become easier once GDB supports DWARFv6? | ||
