--- Comment #4 from hadack at gmx.de --- I have the same problem on a 7750 CAPE VERDE card. When starting a xfce session X craches with the error message from above, starting kde works fine. bisecting shows this bad commit: 8a72c73032707c7b3c042b716286a1ac33720991 is the first bad commit commit 8a72c73032707c7b3c042b716286a1ac33720991 Author: Tom Stellard <thomas.stellard at amd.com> Date: Mon Jun 3 17:39:46 2013 +0000 R600/SI: Fixup CopyToReg register class in PostprocessISelDAG() The CopyToReg nodes will sometimes try to copy a value from a VGPR to an SGPR. This kind of copy is not possible, so we need to detect VGPR->SGPR copies and do something else. The current strategy is to replace these copies with VGPR->VGPR copies and hope that all the users of CopyToReg can accept VGPRs as arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk at 183132 91177308-0d34-0410-b5e6-96231b3b80d8 -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
