            Bug ID: 97887
           Summary: llvm segfault in janusvr -render vive
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: haagch@frickel.club
        QA Contact: dri-devel@lists.freedesktop.org

Created attachment 126700
  --> https://bugs.freedesktop.org/attachment.cgi?id=3D126700&action=3Dedit
stderr output with R600_DEBUG=3Dvs,tcs,tes,gs,ps,cs

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Ellesmere [Radeon RX 480] (rev c7)
mesa git, linux drm-next-4.9-wip, llvm 4.0.0svn_r282018

So I'm trying to start janusvr -render vive with the steamvr-osvr steamvr
plugin. Because osvr-rendermanager still doesn't do core profile, I start it
with

MESA_GL_VERSION_OVERRIDE=3D3.3COMPAT MESA_GLSL_VERSION_OVERRIDE=3D330 ./jan=
usvr
-render vive

But llvm segfaults:

Thread 12 "si_shader:1" received signal SIGSEGV, Segmentation fault.
