In short, the miscompilation happens at "cmp" instruction where the destination
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=nosb".

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    //<===== 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 needs
more changes in the follow up instructions.

With NINE_DEBUG=ps R600_DEBUG=ps the buggy shader looks like this:
