The Motorola DSP hotline compiler support is for people who are registered users of DSP56KCC. You apparently don't have DSP56KCC. It's no wonder that the poor support engineer was a little confused by your claims of illegal instruction sequences. Did you explain to the engineer that you had built your own version of the compiler, using the source from a ftp site? If you want to use the released diffs to generate code or whatever, that's great. I think it's great if anyone gets extra mileage from the work that was done, and if anyone finds any genuine problems, I'd love to hear about them. However, if you want the complete compiler system, and the Motorola DSP hotline compiler support that comes with it, then you have to pay for it. Sorry. Does the compiler work? Yes. Will we find bugs in the future? Probably. Does DSP56KCC generate illegal instruction sequences on the order of which you suggest? No. I apologize if I come across as being a little harsh, but I really feel the need to set the record straight. thanks, Jeff Enderwick jeff@dsp.sps.mot.com
