What are you doing now?

OK OK You dont need to get mad.

Code:

xor eax,eax
push eax
call _exit
leave
ret

What does that do?

smeezekitty · 04-12-2010, 01:21 PM

It should be equivlant of exit(0); in C.
BTW If you think x86 asm hurts your brain, look at powerpc asm:

Code:

	.file	"powerpct.c"
	.section	".text"
	.align 2
	.globl main
	.type	main, @function
main:
	stwu 1,-16(1)
	stw 31,12(1)
	mr 31,1
	li 9,0
	ori 9,9,64000
	addi 9,9,-1
	mr 0,9
	mr 3,0
	lwz 11,0(1)
	lwz 31,-4(11)
	mr 1,11
	blr
	.size	main, .-main
	.ident	"GCC: (GNU) 4.0.0"
	.section	.note.GNU-stack,"",@progbits

I can't say x86 asm is that bad once I got used to it, but that looks completely unintelligible!

What is it even supposed to do?

EDIT: reminds me that I once played around with AVR asm a long time ago, but I didn't understand much of it.

(and I'm still wishing I could do this without the 32-bit VM)

What are you doing now?

What are you doing, now?

Nothing.

The feeling is mutual.

wtf. I'm bored.

Squinting, trying to read the screen. Stupid eye allergies.

MTK358 · 04-12-2010, 03:40 PM

How do you get the division remainder in x86 asm?

Also considering SSHing into my 32-bit VM from my desktop, but I don't understand any of the explanations online.

Or, if possible, SSHing to another 32-bit Linux box on my home network, if I only knew how to do that.

Still wish I can get 32-bit code running on my 64-bit desktop...

Heh, I've got a PDF open right now with a "beginner's" tutorial on AVR assembly. It's not quite as simple as x86, to put it lightly.

It also appears to be heavily based in Windows/AVR Studio.

What's worse, I don't even know if this can apply to my Arduino, or if I'm stuck using the IDE software!

I'd really love to be able to write über-fast programs for the thing; I don't know how well the compiler optimizes the C++ code you write in the IDE.

EDIT: Then again, I can't even get some stupid %$%#$^%$# string parsing code working right now, so maybe I'm too much of a C++ idiot to even be thinking about assembly.

MTK358 · 04-12-2010, 03:46 PM

I don't know, both because I use the avrispmkII programmer, not arduino, and I still did it when I used AVR Studio in Windows.

And anyway, I must say that x86 asm isn't nearly as hard as I thought, it's just that there aren't any good tutorials.

GoinEasy9 · 04-12-2010, 04:01 PM

I used 6502 asm to learn how Atari loaded programs off of disks. It was fun, especially because of limited commands. Let's see, Load the accumulator, goto the accumulator ... FIRE the accumulator. Oh, just remembered, Atari had a lot of video games (I might have not remembered the commands correctly). Now, back to the regularly scheduled thread that won't die.

As long as there are active members of this forum, they have internet access, and as long as they do things, this thread will probably just keep on going...

smeezekitty · 04-12-2010, 04:08 PM

That should be just about infinity.

MrCode · 04-12-2010, 04:27 PM

What I'm doing now:

EDIT: Okay, I solved the problem, but the program is still buggy...

And worst of all, I don't know how to fix it!

Yes, I have anger issues. No, I don't have any patience.

Yes, I probably shouldn't be programming, then. No, I'm not going to stop just because of that.

Grilling steaks and posting from OUTSIDE. It's a real place it turns out. The rumors are TRUE!
