            Bug ID: 103397
           Summary: [regression, bisected] broken geometry in almost every
                    game
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi

2f4705afde707e8eb41b9414c25df91aa1ea2fb3 is the first bad commit
commit 2f4705afde707e8eb41b9414c25df91aa1ea2fb3
Author: Marek Olšák <marek.olsak@amd.com>

    radeonsi: if there's just const buffer 0, set it in place of CONST/SSBO
pointer


This change broke a lot of things on my Pitcairn GPU.

In KOTOR (with Wine) the character animations are broken. In Doom 3 and Quake
Wars the whole geometry is broken. In Cogs the shadows are wrong and the menu
screens are broken. In Furmark the background is fully green. In Unigine Valley
I only see blackness, but Heaven is unaffected. Saints Row 2, Shadow Warrior,
and Witcher 2 are unaffected.

D3D in Wine is curious: Portal 2, Just Cause, Crysis 2 are broken with wined3d
but they're fine with nine, Stalker is fine with both wined3d and nine, Deus Ex
Invisible War is broken with both. Portal 2 is also broken when running
natively.

I've also tested games that use fixed-function rendering, those are unaffected.
(I've also realized that I have too many games installed)

Fixed with
https://cgit.freedesktop.org/mesa/mesa/commit/?id=3f8e3c2bd8f54ae6817f7496be47f4e1a8860d9c

You also need to update LLVM 6.0 from git or switch to LLVM 5.0. Anything in
between will lead to the same corruption.

With llvm 5.0 and mesa master everything is fine. Thanks.
