Apply suppression specifications to added and removed functions and variables Until now, specifications for suppressing change reports were applied only to functions and variables that have sub-type changes. Change reports about function and variables that were added or removed could not be suppressed. This patch makes suppression specifications to apply to added and removed functions and variables too. They can also apply to function and variable symbols that are not referenced by any debug info. The patch also fixes some typo and formatting glitches and updates some existing tests accordingly. * include/abg-comparison.h (is_type_suppression) (is_function_suppression): Declare new functions.

Detect vtable changes from member function changes This patch adds vtable changes detection based on the detection of virtual member function changes. That is, when a member function changes, if that member function is virtual, then infer if the change implies changes to the vtable of the containing class. Before that patch, we were doing the vtable change detection when we were comparing two classes; we were then comparing their virtual member functions. But as for a given class all its virtual member functions are not necessarily emitted in the DWARF debug info (only the virtual member functions that are used in a given translation unit are emitted in that translation unit) it's not reliable to compare virtual member functions as part of comparing a given class. We thus decided some patches ago to stop comparing virtual member functions when we compare two classes. So with this patch now, we still detect changes to the vtable and emit an appropriate message to the user. * include/abg-ir.h (class_decl::{has_virtual_base, has_vtable}): Declare new member functions. * src/abg-comp-filter.cc (has_virtual_mem_fn_change): New overload for function_decl_diff.

(corpus_diff::report): Detect and report changes to vtables by looking at changes change to member functions. * tests/data/test-diff-dwarf/test29-vtable-changes-report-0.txt: New text input. * tests/data/test-diff-dwarf/test29-vtable-changes-v{0,1}.cc: Source code of new test input binaries. * tests/data/test-diff-dwarf/test29-vtable-changes-v{0,1}.o: New test input binaries. * tests/data/test-diff-dwarf/test30-vtable-changes-report-0.txt: New text input. * tests/data/test-diff-dwarf/test30-vtable-changes-v{0,1}.cc: New test input. * tests/data/test-diff-dwarf/test30-vtable-changes-v{0,1}.o: New test input binaries. * tests/data/test-diff-dwarf/test31-vtable-changes-report-0.txt: New test input. * tests/data/test-diff-dwarf/test31-vtable-changes-v{0,1}.cc: Source code of new test input binary. * tests/data/test-diff-dwarf/test31-vtable-changes-v{0,1}.o: New test input binary. * tests/data/Makefile.am: Add the new test input files above to source distribution. * tests/test-diff-dwarf.cc (in_out_specs): Consume the new test inputs above.
