From: Philippe Mathieu-Daudé Date: Thu, 14 Sep 2023 18:57:11 +0000 (+0200) Subject: accel: Rename accel-common.c -> accel-target.c X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e8b845b9b1a172c367bb77e16498664290736ad6;p=qemu.git accel: Rename accel-common.c -> accel-target.c We use the '-common.c' suffix for target agnostic units. This file is target specific, rename it using the '-target' suffix.
