          Priority: medium
            Bug ID: 65085
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [radeonsi LLVM] Segfault during OpenCL kernel
                    compilation
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: niels_ole@salscheider-online.de
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

Created attachment 79901
  --> https://bugs.freedesktop.org/attachment.cgi?id=79901&action=edit
Kernel that causes the segfault

I get a segmentation fault in LLVM with Tom Stellard's recent radeonsi compute
patches
(http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130520/175743.html)
with the attached kernel.

I can work around the issue when executing the if-block in the kernel
unconditionally or with the attached patch to LLVM.
Desc.OpInfo[0].RegClass equals -1 when the segmentation fault occurs.
