I forgot to mention that this used to work couple of months ago. Can you bisect? (In reply to comment #2) > Can you bisect? 217cd216eac65983004ca77a9e49dbfad1b720b6 is the first bad commit commit 217cd216eac65983004ca77a9e49dbfad1b720b6 Author: Tom Stellard <tstellar@gmail.com> Date: Tue May 17 18:51:20 2011 -0700 r300/compiler: Fix bug in rc_get_variables() Variables that write to the same source select need to pe paired together otherwise the register allocator might fail. https://bugs.freedesktop.org/show_bug.cgi?id=36753 :040000 040000 a1d3852986919d6ae3449a06a8b3dc43afe90689 2a8531a9541ae918d70bff7911025fed709e7b6b M src I think this issue is duplicate of #36939, despite looking entirely different, bisect found the same commit. Created attachment 51277 [details] [review] Verbose patch Can you apply this patch and post the output of RADEON_DEBUG=fp again? Created attachment 51284 [details]

I applied the reverse of commit 217cd216eac65983004ca77a9e49dbfad1b720b6 to the compiler, and recorded stderr again with correct rendering.
And this time I didn't forget to compress it before uploading.
Created attachment 51295 [details] [review] Possible Fix Can you try this patch? If it doesn't work, can you post the output again? The patch fixed this one and #36939. Thanks. Fixed in git commit 2d1004d9aa719bb93a4f057b0eefe88f23b44e44 |

Created attachment 50186 [details] stderr with RADEON_DEBUG=fp With shader detail=high the strogg radar becomes completely black. I think this corresponds to the two compiler errors (log attached).
