From c057278c065747c1f53579504bf109cafb7cb390 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Thu, 1 Sep 2016 19:36:23 -0700 Subject: [PATCH] i965/fs: Stop using fs_reg::in_range() in favor of regions_overlap(). Its only use left in the FS back-end should be using regions_overlap() instead to avoid getting a false negative result in cases where source and destination overlap but the former starts before the latter in the VGRF file. v2: Put back lost components factor (Iago).
