From b480f7a621c8a896aa7a79b22f179c3c153f3adc Mon Sep 17 00:00:00 2001 From: Pierrick Bouvier Date: Tue, 5 Mar 2024 12:09:54 +0000 Subject: tests/plugin: add test plugin for inline operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For now, it simply performs instruction, bb and mem count, and ensure that inline vs callback versions have the same result. Later, we'll extend it when new inline operations are added. Use existing plugins to test everything works is a bit cumbersome, as different events are treated in different plugins. Thus, this new one.
