1 Added variable:
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. ({function, variable}_suppression::change_kind): Declare new enum.
