Reasons to use asm?

I doubt that any compiler will be able to write code as well as a human doing ASM by hand. And its a challenge too, it expands the intellect, and best of all it makes most other languaes look flabby and slooooooow (and easy).

I like to write code that performs as fast as it can for any given language, ASM happens to appeal to that side of me. I'll be using ASM mostly for spot-tuning my C# programs.

It certainly does not expand the intellect. It is simply another tool for getting the machine to do what you want it to do.

There are many people on this forums who have been using ASM for years; writing support DLL's, for instance.

This smells of some sort of elitist cr@p.

Did I say something to make you angry? I have nothing against high level languages and I like ASM so I don't see why you are getting all upset.

Nobody is being elitist.

Oh, let's just be elitist and only let people in the club who have more then one "standard vowel" in their names :D

I agree.'a' counts for two vowels, though.

I'm always angry. The wife needs to learn how to stop burning my toast in the morning.

But still the VectorC output will beat it to deth.

Noteme...just wondering...did you set the Intel compiler to compile for P4 and SSE/SSE2 architecture ? If you didn't it wouldn't produce SSE/SSE2 code.

btw...those you took from the VectorC website...they were using MSVC 6 and Intel Compiler 5
It is now coming MS VC 2005 .NET and currently is Intel Compiler 9.

Im not saying Vector C is bad as I have nevre tried it nor have tested it. But the source codes you are showing us are of really old versions of the other compilers. MSVC 6 came out before SSE2 was released i think(SSE maybe only just) and Intel Compiler 5 is old....very old 4 versions ago.

I believe they will all produce similar code now. Probably MS being the worst.

Sorry for bringing up an old thread but I agree with "one big bloated compiler" - not for VB6, of course - I love it's simplicity and non-fanciness - but for todays compilers such as Delphi 2005 and Visual Studio.NET. Way too bloated and color-fancy. I don't know about you but I prefer the olden-style compilers like Delphi 6-7 and Visual Studio 6. No bull**** and fancy colors - just nice and simple.

Thus, bloatedness and fancy colors = the reason I refuse to upgrade languages. Stupid? maybe. Get used to it? No. I can't stand looking at it, let-alone using it.

Ummmm......we aren't talking about IDE or the libraries that go with languages.... we're talking about code generation! :P
