Except that real world tool are always buggy, so when you see something, you waste time wondering if it is a tool bug or artefact or a real bug. And I am not only talking about free software, I have used expensive symbolic debug tools connected to JTAG, it was as buggy as the rest. -- Gilles. -------------- next part -------------- A non-text attachment was scrubbed...
