<0> How do you do unsigned operations in AT&T syntax x86 asm ?
<1> which operation ?
<0> comparison
<2> quickly, anyone tried doing windows ***embly in linux?
<0> cmp
<2> and perhas run the result in wine??
<1> comparison are the same for signed and unsigned
<0> er are you sure ?
<1> why do you ask us if you don't want our awnsers ?
<0> I was just asking if you were sure -_-
<1> yes i am
<0> mov $1, %eax
<0> cmp $-1, %eax
<0> jg foo
<1> jg is unsigned
<1> cmp is not
<0> Ah
<0> I see
<1> err
<0> So is there a signed version of jg ?
<1> jg is signed ja is unsigned
<1> jl is signed jb is unsigned
<0> Ah okay
<0> Thanks
<3> steffylove, it can be done.
<4> EEEEEEP
<3> steffylove, I haven't personally done it, but I know for a fact it can be done.
<4> ah, no, ok. nevermind.
<3> markos_64, why the panics?
<4> bill[1]: a mental glitch.
<3> darn those glitches.
<2> bill[1]: hmm, well i tried using wine.. i compiled something using a86 which went fine.. but the generated com doesnt run with wine.. im hitting my hopes on dosemu.. emerging it now even
<2> yeah
<0> ugh
<0> How come I can't go mov %ebx(%esp), %eax :\
<0> Error: junk `(%esp)' after register
<0> :(
<4> Ykstort: mov (%ebx,%esp,1), %eax
<4> er, mov (%esp,%ebx,1), %eax
<5> What ***embler is that syntax for?
<4> gas
<4> or any AT&T thingie
<0> markos_64, and I need the 1 too ?
<4> hm.. dunno. but it doesn't matter. the generated opcode will be the same.
<0> ah right
<5> Have you guys seen this yet: http://www.microsoft.com/windows/virtualpc/default.mspx
<5> MS Virtual PC free
<5> don't think it will run on my computer, though :(
<1> you need PII
<5> PII?
<1> P2
<5> You mean, a Pentium II processor?
<6> is the stack a physical or virtual? does the operating system create it?
<7> the stack is mythical
<7> the operating system bows to its magnification!
<6> phrosty, you are a real artist
<6> :)
<6> asm is your paint brush
<7> sniffing too much paint, maybe!
<6> I prefer charcoal
<5> So, is the stack real or not?
<6> the stack is created by the operating system to manage calls :)
<6> it's software based in most pc's but can be hardware based in others :P
<6> I hope im right
<6> :P
<6> managed by software
<5> you just said it was managed by the OS...
<6> yes
<6> but the cpu ***ists
<6> with stack pointer
<6> the cpu ***ists the operating system do its dirty work
<5> Say, if you know this already, why did you ask?
<6> java has its own stack in its virtue machine
<6> because by the time you all gave me the answer Google had done so already
<6> :P
<6> the question is... why do I want to know this? do i want to take over the world? yeah why not... :P
<6> ***face - nice to meet u
<6> :)
<8> Yeah, likewise.
<6> I wonder if the a in asm stands for *** too :)
<5> I thought ASM was an abbreviation of "***embly"
<6> yes but after you start using it... it become ***... a pain in the ***
<8> Maybe the A alone stands for '***embly', and the other two letters stand for something exceptionally sinister.
<6> ***embly *** maniac? :)
<8> I was thinking ***embly sadism and masochism
<6> ahh yes that makes sense
<5> okay, you guys are weird
<5> Then again, we're on IRC.
<6> Dacicus - weird is relative
<6> :)
<8> Heh. While I've only been learning ***embly for a week.. I think I could see how *** acts combined with its use could be a titillating experience.
<6> lol
<6> Smokin
<6> a creative programmer very nice
<6> :)
<8> Haha.
<6> maybe you can design me a virtua woman ;)
<6> might take you a lifetime but hey... when im old and rusty she'll be perfect :P
<8> Heh
<6> the big question is
<6> do modern pc's still suffer from 640k conventional memory space? and have to keep swapping data in and out of there?
<5> Wasn't that a DOS Issue?
<5> issue*
<6> most probably
<6> :)
<6> just looking at a memory map of 2001
<6> pc memory map
<6> and I still see it has the 640k area
<6> for applications
<6> :/
<6> hma memory access is most likely used these days without problems and virtua memory mmmm
<6> which is fun
<6> well i guess memory management and crypto coding is the most fun for super geeks :P
<6> I asked that question in #windows chan they don't have a clue :P
<6> that's what microsoft does... turns you into a vegetable
<5> Did you expect them to?
<6> Nope
<6> but I did DARE to ask :P
<5> your courage is commendable ;)
<9> can someone tell me why i cant show MZ at the end of my file with this program
<9> http://rm3d.free.fr/temp/openpe.asm
<9> http://rm3d.free.fr/temp/openpe.inc
<9> (please)
<5> Windows ***embly :(
<5> oh, sorry, don't mind that
<5> just my personal prejudice against Windows etc.
<9> oh
<9> you use linux ?
<5> No, I use WinXP.
<5> But I prefer DOS
<9> okay
<9> im just trying to open a file and read the content but i dont know how to use
<9> it think its called file mapping ?
<9> lol
<8> http://databsod.ytmnd.com/
<8> Holy smokes, it's Brent Spiner
<10> Why If I write 11000111 as a modr/m byte for MOVD instruction, it decodes as movd edi, mm0 but not mod eax, mm7 ?
<10> what am I missing?
<5> Hm, those ytmnd things generally don't work for me for some reason.
<8> Well, it's basically incontrovertible proof that LCARS is windows-based.
<5> What's LCARS?
<8> It's the OS that Federation starships use
<3> LCARS?
<8> http://en.wikipedia.org/wiki/LCARS
<3> my we've gotten geeky.
<8> lol
<10> bill[1], do you know that modr/m issues?
<3> er, what?
<10> "Why If I write 11000111 as a modr/m byte for MOVD instruction, it decodes as movd edi, mm0 but not mod eax, mm7 ?"
<10> *not mod eax ...
