The new name makes the sense of the condition much clearer. E.g. compare: NS_WARN_IF_FALSE(!rv.Failed()); with: NS_WARNING_ASSERTION(!rv.Failed()); The new name also makes it clearer that it only has effect in debug builds, because that's standard for assertions. --HG-- extra : rebase_source : 886e57a9e433e0cb6ed635cc075b34b7ebf81853
