From a5b71725c7067f6805eb30ff8e03dce3b6bf7a53 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 14 Aug 2012 12:53:18 +0200 Subject: xbzrle: fix compilation on ppc32 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When compiling the xbzrle code on my ppc32 user space, I hit the following gcc compiler warning (treated as an error): cc1: warnings being treated as errors savevm.c: In function ‘xbzrle_encode_buffer’: savevm.c:2476: error: overflow in implicit constant conversion Fix this by making the cast explicit, rather than implicit.
