From d54ca54faa2a6dde3c4d2125fd41d10dfcf2f91e Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Sat, 17 Oct 2015 21:51:24 +0100 Subject: [PATCH] pipe-loader: rework the sw backend Move the winsys into the pipe-target, similar to the hardware pipe-driver. v2: - move int declaration outside of loop (Brian) - fold the teardown into a goto + separate function.
