I think a combination of the first and the third would look best, by superimposing the reflection on the water pattern. This would basically mean that you’d use a darker pattern, but still not a complete fill, where both images are black.

The culprit must be the printf() function, which is infamous for its size. It must be avoided at all costs.

Perhaps we could check the sign flag. It should be M if BC >= DE and P otherwise, right? I haven't thought that one through at all - it's just a guess, so I may be wrong. That wouldn’t be enough, because B can be so much greater than D that the difference goes below -128. You’d have to check the ov...

Carry flag set if BC > DE.
Zero flag set if BC == DE.

Indeed, I knew I was overlooking something trivial.

That’s what happens when you stop dealing with low-level stuff...

What about doing it byte by byte?

Code: Select all

ld a,d
cp b
jp c,bcIsBigger
jp nz,deIsBigger
ld a,e
cp c
jp c,bcIsBigger
jp nz,deIsBigger
<they are equal here>

CoBB, PindurTI is losing in popularity against WabbitEmu... :( Why is that a problem? Wabbit is superior in practically every respect. :) I'll hack it as a second backend into my new Linux frontend for WabbitEmu, so I don't give either project an advantage, but if PTI wants to survive you really ne...

And then comes the deeply philosophical question whether something is a bug or a feature.

The only viable software solution would be to use an interrupt handler to check the state of the program counter, as GuillaumeH described. Well, if you set the interrupt to the highest speed, you can regain control about once in 1000-2000 instructions (10-11k cc). That might catch some nastiness, b...

So, you're not going to work with Java because apearently everybody hates it, which leaves .NET -- and hoping that Mono will get there "some day" Unless the app heavily relies on IE, in which case that ‘someday’ is pushed even farther... I'll just have to keep working with a simple editor...

Same goes for Java as a language and as a system. I don't really understand how so many people can hate it so much :) For instance, deploying Java programs at different machines is often impossible without recompilation. I’m teaching Java in this semester (and did last year too), and you have no id...

Sorry about the obscure indirections in the reference, it’s to make sure that only people who understand pointers will make use of it.

Yes, that’s how I understood it.

CoBB

I thought the same thing as CoBB, but to solve this, one can imagine source code annotations to mark areas that must not be rewritten (SMC parts mostly). That’s unfortunately a chicken and egg problem of some sort. Since the optimiser has limited means to find out what effects you want to preserve,...

CoBB

This can be tricky though, because the side effects might change in surprising ways, and such changes might break the program if the code relies on a certain behaviour of flags for instance, not to mention SMC (which is most likely not an issue with a C compiler though)...
