This tests the new dwarf_getlocations, dwarf_getlocation_attr and dwarf_getlocation_die functions. But it is also an example of how to handle location expressions and which libdw functions can be used to access all information required to interpret each DW_OP. It might make sense to extend this test/example into a program that verifies various properties of DWARF expressions. Signed-off-by: Mark Wielaard <mjw@redhat.com>
