Whether Motorola should feel proud of their compiler is a question that is different from What is this stuff on a computer in Finland. My answer to the former is No, but I do hope you'll keep trying. I paid $700 cash for the original attempt. Before deciding whether to upgrade, I asked Motorola some questions. No, it does not do pipeline optimization. No, data in x, y, p memory spaces are not supported; you have to choose either x or y and not both. No, it does not have a fractional data type (can that really be true?). Well, I decided to hold off and stick with the one I made from Dave Dunfield's 8086 C compiler. Motorola has won every design-in I've done since the chip was announced, except when the decision was based on price rather than technical merit. A DSP56000 can do three things in one instruction. But if the compiled code takes ten instructions to do one thing, what good is that? I didn't buy a DSP chip to go slow. I won't buy software that makes it go slow. Perhaps TI is the only DSP company that can *afford* a real compiler project. TI, with its near-monopoly market share, has improved its software from awful in 1982 to very good in 1992. (But I can't use their chip any more! It always seems to work out slower than the alternatives.) Meanwhile the other companies presumably do what software support they can, but they sure leave a lot to wish for. I say, Never mind the windows and COFF and source level debuggers, just give us a better compiler.
