I pulled 1 of the 3 failing shaders from the error log. If you have some familiarity with assembly code, you can look through the log and try to find optimization opportunities that would reduce the number of instructions we need to emit. This would be very helpful. I would recommend looking at the code after the dataflow passes, because at this point most of our optimizations have already been done. If you are unsure of what the instructions do, their definitions are in this file: src/mesa/drivers/dri/r300/compiler/radeon_opcodes.h
Thanks for having a look at the bug! Unfortunately I don't think I can be of much help, this sounds like something well above my meager skills.
