With two relatively new compilers around, it's time to get into flame wars: Who has used Lattice C 4.0 and/or Manx C 3.4 ? Lattice, in their ads, claim: Lattice 4.0 Manx 3.40 ----------- --------- 1294 Dhrystones versus 1010 IEEE Float in 22.2 s versus 98.85 s FFP Float in 10.16 s versus 17.60 s IEEE Savage in 47.67 s versus 119.6 s at .000000318 at .000109 accuracy accuracy Of course, these will be lies, but what's the truth of the matter ? I know the Amiga Transactor is planning a comparison of the two, but in the meantime, what's the experience of netters ? Even if Lattice does perform better in the above tests, that says nothing about the quality of their libraries, other than FP, which I am told has always been abysmal. And of course Manx still has a source level debugger, and I have no idea if Lattice plans one in the near future. Any comments ? Absolutely no flames about older Lattice or Manx versions! With one exception: does code that compiles properly under them break under the new compilers ? And how easy is it, now, to port between the two ? Unrelated question: ------------------ How, exactly, does the Commodore monochrome monitor work ? Worst case: outputs four screens arranged 512x400 or 1024x200 to produce one picture. Takes much time to do this, and is very long persistence. Text smear worse than a six year old with a peanut butter sandwich reading your tabloid newspaper on a hot day. Best case: Something I haven't thought of yet. George? If the worst case above is not the answer, when will it be available ? If it is, I really don't care.

First of all, the latest Manx (so new it's not even here yet :->) is 3.6, not 3.4. The source level debugger is a 3.6 enhancement. Secondly, forget benchmarks. I'm sure you could come up with a Seive that used the blitter. Does that mean the Amiga as a 10 MIPS machine? Take a real program and compare its speed under both. I'd suggest something large, portable, and CPU-bound. Like ADVSYS. Finally, what features do the two variants give you? What features do you want? As for the monitor, I believe it takes a 4 bitplane screen, pulls out the bitplanes, and sticks them next to each other. Suitably scrolled, of course, so they all fit into one bitmap. -- -- Peter da Silva `-_-' ...!hoptoad!academ!uhnix1!sugar!peter -- Disclaimer: These U aren't mere opinions... these are *values*.
