Are there any plans to add support to libunwind for the case when only
.debug_frame sections are present?

Debug sections are not loaded, so they are not available at runtime.


That's an excellent point that I hadn't considered. It could slow down unwinding significantly, and the user would be puzzled as to why after he [accidentally] removed the -funwind-tables (etc.) option that his application just became much slower.
