<0> what do you think of efficeon proc all ?
<1> I'm running linux, and I have wine installed. I want to develop ***embly programs for Win32 on this linux system.
<1> how can I ***emble them with Nasm in a way that they can be linked with VC++ _or_ with freely available tools?
<1> and*

<2> what mov eax, [ebp-48h] do?
<2> what does*
<2> im trying to understand eax, ebx, ecx etc
<2> but ebp-48h?
<3> ebp is another register.. stands for base pointer
<2> hm
<2> but why the -48h
<2> what does that change
<2> sorry, i just started learning today
<2> so i got millions of questions haha
<2> reading through all these different papers
<3> phailure: [ebp-48h] means the value at the location (ebp - 48h)
<3> read about indirect addressing mode
<3> also read something like this for an overview on what registers are useful for what: http://www.swansontec.com/sregisters.html
<2> alrighty
<2> im reading through pcasm-book.pdf right now
<2> im kinda stumped on this though
<2> 047C0
<2> +0048
<2> 04808
<2> or 047C0 + 0048 = 04808
<2> Isn't C = 12?
<2> So how is c+4=10?
<3> 0 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 12, etc.
<3> read on hexadecimal
<2> well so A = 10, B = 11
<2> to F = 15
<3> yes.. 10 (hex) is 16 (decimal)
<3> c+4 = 10 (hex) => 12 + 4 = 16 (dec)
<2> whoa im lost
<2> So whats 9 hex
<1> 9
<1> numbers less than 10 are the same in both decimal and hex
<1> (that's less than A in hex)
<4> i repeat "what do you think of efficeon proc all ?"
<5> 8B EB 91 7C 94 EB 91 7C
<5> i need to dis***emble these few bytes..
<6> echo -e "\x8B\xEB\x91\x7C\x94\xEB\x91\x7C" | ndisasm -
<6> ?
<6> they don't make much sense
<5> why Spark?
<5> well i don't have ndisasm here, unfortunately
<6> is it x86
<5> yes..
<5> of course
<5> why?
<7> hi i m new to MIPS, can anyone help me or guide me where i could find some good material
<8> What are some good ide for ***embly?
<9> Notepad.
<8> Heck, i will use a pen and paper
<8> why even respond?
<10> sOra: emacs, masm32 (qeditor) :)
<8> ok d00zer, will look inot it :-)
<10> masm32.com/board - > IDE Development and Support
<8> k
<11> I'm in win32.. What would I use if i want to compile a single statement to get the bytes produced... like if i were to patch a running process...
<8> d00zer
<8> still here?
<10> yeah
<8> can asm be learned to replace C++ etc?
<12> in the same way that you cn learn to build a house molecule bu molecule rather than brick by brick
<10> not for writing code fast.
<12> or house by house, tbh
<8> What would be the advantage?
<8> besides faster execution i beleive.
<12> not much, if you want t do high level programming, you ought to use a high level language
<8> so ***embly is strictly for hardware based programming?
<12> well, unless you're mad, yes
<8> well, what im trying to say is, that is what people use it for, right?
<8> ok
<8> lol
<12> yeah. I use asm in things like cpu abort handlers, when there's not much of an environment for a high level language
<8> ok
<13> Hello.
<13> I am writing a procedure in NASM that will be called from C code.
<13> It will be p***ed one parameter, of type 'int'
<13> Will this put that parameter in to eax:
<13> pop eax
<13> Or is there a different code I need to use to get the contents of the parameter in to EAX?
<14> AWOSLappy: ?
<14> AWOSLappy: C calling convention puts arguments to stack
<14> yes
<13> right
<13> so I would just "pop eax" and the parameter is now in EAX, correct?
<14> no
<14> AWOSLappy: that would hold the return value
<14> AWOSLappy: how else could you return? ;)
<14> usually you do: push ebp; mov ebp, esp; mov eax, [ebp+8]; do something with first argument; leave; ret
<14> AWOSLappy: second argument would be in [ebp+12] and so on

<13> lindi- does that look about right?
