Using dwarf_getscopes_die we can get all scopes that make up the current subprogram representing an address. Using the call_file/line/column attributes we can also show the source locations of these "inlined" calls. Includes a test that shows that when DWARF debuginfo is available all inlined function call frames and their source location can be shown. Signed-off-by: Mark Wielaard <mjw@redhat.com>
