I will probably not have time to test this in the foreseeable future, so unless
someone else can, I don't mind if the bug is closed.

It could be. That FS input may contain random values because it's
uninitialized, potentially leading to pixels being influenced by it, resulting
in sort of random corruption. It depends on the shader and how much the input
contributes to the final pixel color.

There's still a problem with rendering issues when shader quality is set to
anything higher than "Low". I was just wondering if this is related to the
hardware limitation (the "FS input generic 17 unassigned" warning) rather than
bug?

The problem remains (corrupt rendering with medium and high) but seems to be
slightly different now. I have uploaded new screenshots:

high:
http://www.flickr.com/photos/whizse/5201781578/

medium:
http://www.flickr.com/photos/whizse/5201187031/

all previous screenshots are here, for comparison:
http://www.flickr.com/photos/whizse/

I also noticed this error message:
 r300: ERROR: FS input generic 17 unassigned, not enough hardware slots.

Let me know if you need new debug dumps or screenshots with noopt.

Done

The regression happened right after the glsl2 merge. I don't think it's
possible to pinpoint it down any further.

Thanks, this was helpful.  Can you post the output of RADEON_DEBUG=fp on master
with both medium and high settings.

Also, is there any chance that this is a regression that can be bisected?

This patch with noopt seems to be the best result yet.

I made a bunch of screenshots, comparing llvmpipe with master, master+noopt,
the patch, and the patch+noopt: http://www.flickr.com/photos/whizse/

No difference with or without setting RADEON_NO_TCL as far as I can see.

Hmm... I get a different result with noopt, the corruption is less noticeable,
mostly in the borders around the water, but the actual visual effect seems to
be missing. 

I'm attaching a log with RADEON_DEBUG=noopt,fp,vp

Can you try it again with RADEON_DEBUG=noopt.  If this fixes it, can you post
the output with RADEON_DEBUG=noopt,fp,vp _and_ RADEON_DEBUG=fp,vp.  If this
doesn't fix it, can you post the output with RADEON_DEBUG=noopt,fp,vp
