From 369276ebf3cbba419653a19a01b790f3bcf3aea7 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 25 Nov 2019 14:38:45 +0100 Subject: [PATCH] util/cutils: Turn FIXME comment into QEMU_BUILD_BUG_ON() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit qemu_strtoi64() assumes int64_t is long long. This is marked FIXME. Replace by a QEMU_BUILD_BUG_ON() to avoid surprises. Same for qemu_strtou64(). Fix a typo in qemu_strtoul()'s contract while there.
