            Bug ID: 102905
           Summary: [R600] Miscompilation of TGSI to VLIW causes artifacts
                    in Gallium Nine with Crysis2 bump mapping
           Product: Mesa
           Version: 17.2
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: iive@yahoo.com
        QA Contact: dri-devel@lists.freedesktop.org

In short, the miscompilation happens at "cmp" instruction where the destina=
tion
register is also one of the source registers.

I suspect that the problem is caused by breaking "cmp" on two operands that=
 are
executed in different VLIW, thus the result of the first one changes the
outcome of the second. Using a temporal register in "cmp" workarounds the
issue.

The bug is NOT related to Shader Backend. Artifacts are still visible with
"R600_DEBUG=3Dnosb".

A D3D9 apitrace could be obtained from the ixit Nine ftp.
The bug is also tracked at https://github.com/iXit/Mesa-3D/issues/288 .

My hardware is Radeon HD5670 (Evergreen, Redwood).
Not reproducible on Radeon SI.

Bellow are D3D9 Pixel Shader, TGSI and R600 VLIW assembly:

--------------------------------------------------------------

Making the following change in the above code:
---
-    cmp_pp r0.xy, r0.x, r1_abs, r0.ywzw    //<=3D=3D=3D=3D=3D this one
+    mov r8, r0
+    cmp_pp r0.xy, r8.x, r1_abs, r0.ywzw
---
workarounds the issue.
Alternative workaround is using different destination register, it just nee=
ds
more changes in the follow up instructions.

With NINE_DEBUG=3Dps R600_DEBUG=3Dps the buggy shader looks like this:

        <div>
        <pre>In short, the miscompilation happens at &quot;cmp&quot; instru=
ction where the destination
register is also one of the source registers.

I suspect that the problem is caused by breaking &quot;cmp&quot; on two ope=
rands that are
executed in different VLIW, thus the result of the first one changes the
outcome of the second. Using a temporal register in &quot;cmp&quot; workaro=
unds the
issue.

The bug is NOT related to Shader Backend. Artifacts are still visible with
&quot;R600_DEBUG=3Dnosb&quot;.

A D3D9 apitrace could be obtained from the ixit Nine ftp.
The bug is also tracked at <a href=3D"https://github.com/iXit/Mesa-3D/issue=
s/288">https://github.com/iXit/Mesa-3D/issues/288</a> .

My hardware is Radeon HD5670 (Evergreen, Redwood).
Not reproducible on Radeon SI.

Bellow are D3D9 Pixel Shader, TGSI and R600 VLIW assembly:

Making the following change in the above code:
---
-    cmp_pp r0.xy, r0.x, r1_abs, r0.ywzw    //&lt;=3D=3D=3D=3D=3D this one
+    mov r8, r0
+    cmp_pp r0.xy, r8.x, r1_abs, r0.ywzw
---
workarounds the issue.
Alternative workaround is using different destination register, it just nee=
ds
more changes in the follow up instructions.

With NINE_DEBUG=3Dps R600_DEBUG=3Dps the buggy shader looks like this:
