From b95d6588f2750a6b68ab02e232220bbc0d8dbcbe Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Wed, 14 Nov 2018 17:21:30 +0400 Subject: [PATCH] tests: add /vmstate/simple/array MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A very simple test to show VMSTATE_*_ARRAY usage and result. It could be systematically extended to other primitives, but I leave that as an exercise for others :).
