Subject: Add a new corpus_diff::has_net_changes() entry point
X-Git-Tag: 1.0.rc0~177
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=915bf047fb0a7f0c23ba9bd34c79641f93a5b6b8;p=libabigail.git

Add a new corpus_diff::has_net_changes() entry point

This entry point is to test if there are still ABI changes between two
corpora after applying suppression specifications.

	* include/abg-comparison.h (corpus_diff::has_net_changes): Declare
	new member function.
	* src/abg-comparison.cc (corpus_diff::has_net_changes): Define it.
