            Bug ID: 101401
           Summary: [REGRESSION][BISECTED] GDM fails to start after
                    8ec4975cd83365c791a1
           Product: Mesa
           Version: git
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org

I rebuilt/installed mesa earlier this evening and not long after, my system
hung.

Upon reboot, the GDM login screen was corrupted and attempts to login caused
gnome-shell to crash almost immediately after.

Hardware: AMD Ryzen R7 1700, Radeon HD 7850 1GB
Software: Ubuntu 17.04 64-bit with LLVM/Mesa from trunk/git.

A bisect run shows this as the culprit:

8ec4975cd83365c791a1852a6515ed5d4ade2daf is the first bad commit
commit 8ec4975cd83365c791a1852a6515ed5d4ade2daf

    st_glsl_to_tgsi: don't try and pass 32-bit values to get_deref_offsets

    Just use a temporary 16-bit index.

    This fixes coverity issue, pointed to me by Ilia.
