From ef860047b61ea4a5ad407496ab8cda6370a2d7d8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Fri, 5 Jul 2019 12:56:35 +0100 Subject: tests/tcg: fix diff-out pass to properly report failure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A side effect of piping the output to head is squash the exit status of the diff command. Fix this by only doing the pipe if the diff failed and then ensuring the status is non-zero.
