1 function with some indirect sub-type change:

  [C]'function void foo(const S&)' has some indirect sub-type changes:
    parameter 0 of type 'const S&' has sub-type changes:
      in unqualified underlying type 'S&':
        in referenced type 'struct S':
          1 data member insertion:
            'static char S::m0'

1 Added variable:
  'static char S::m0'
Really detect static-ness of data members. Oops. * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Let's consider that a data member being not laid out (i.e, not having a data_member_location) is is a static data member. Otherwise, we were not detecting static data members at all. Well we were only inferring their presence from seeing the static variable definition later on. That means we were missing most of the static variables. Woops. * src/abg-comparison.cc (corpus_diff::priv::ensure_lookup_tables_populated): Now that we are really seeing static data members, let's be prepare to the fact that we can the same static data member being declared several times in a corpus. * tests/data/test-diff-dwarf/test7-report.txt: New test input file. * tests/data/test-diff-dwarf/test7-v0.cc: Likewise. * tests/data/test-diff-dwarf/test7-v0.o: Likewise. * tests/data/test-diff-dwarf/test7-v1.cc: Likewise. * tests/data/test-diff-dwarf/test7-v1.o: Likewise. * tests/test-diff-dwarf.cc: Update this to consume the new test input files. * tests/Makefile.am: Update this to add the missing test files to the source distribution.
