The reason Xilinx won't open source their toolchain, I'm guessing, is that it would reveal to their competitors the optimizations they are using to get more speed or density. Benchmarks and business are won on speed and density (how much I can fit on a given part, and how fast it runs). I can't think of many software projects that had active business competitors (taking sales away from them) that went open source. I don't think code quality has anything to do with it.
