From 9806b9ab5c7fb2ac5efd8ffa8713fea0c5fd218d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Storsj=C3=B6?= Date: Mon, 1 Aug 2016 09:04:33 +0300 Subject: [PATCH] Revert "Don't use expressions with side effects in macro parameters" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 25bacd0a0c32ae682e6f411b1ac9020aeaabca72. Since 230b1c070, the bytewise AV_W*() macros only expand their argument once, so revert to the more readable version of these.
