Description Bruno Jiménez 2014-03-31 21:57:17 UTC

Starting with llvm revision 204072:

commit 2683baa8acbcfc44b94a7af781c43674d28d9a2e
Author: Matt Arsenault <Matthew.Arsenault@amd.com>
Date:   Mon Mar 17 18:58:11 2014 +0000

    R600: Match sign_extend_inreg to BFE instructions


Some of the tests from Opencv OpenCL have started to fail, for example test 'Arithm/Absdiff.Mat/3'

My system is an Arch Linux with Kernel 3.13.7 and mesa from git at commit 3a8bd97. My card is an AMD HD5470 (AMD CEDAR)

If any more information is needed, just ask.
