Be sure to disable optimization in the compilation and linker. "objdump" has an option to include the source lines with the disassembly listing, and when used with another option to mark the beginning of each source line, you can better see how the code is generated. I learned assembly on PDP-11 first, 6502 and 8080 after that (1978). Many architectures since, and still at it.

Very well done, but let me add that you should let listeners know that you could be writing assembly in 2 ways ... one with an operating system (OS) or one with no OS, also known as "running on bare metal". If the latter, there is no use of system calls because you don't have a system ... your program has direct access to all the hardware of the chip. This is usually true of microcontrollers that aren't using a real-time OS.

Assembly is easy to learn. The hard things imho are: 1) you gotta know how the silicone works whether it is the microprocessor, or another device. 2) being able to visualize a high level function, and breaking it down to microprocessor level. Unless u have special need, and you are a rookie, may I suggest that you either go with: a) starting to use high level language such as C/C mas mas , and learn how to write an interface between high level (eg C) to low level… b) use a simple microprocessor and do some easy stuff eg how to switch a LED on and off (basic stuff) and build your knowledge about the silicone thing Cheers Ps pointers in C/++ is quite easy in assembly. You get the concept in one language, you can easily find it out in the other ie assembly. Investigate the difference between notations like the ones below: ( can be a bit different depending on the processor/assembler): MOV ax, 0x04 MOV ax, [0x1000]

If you're targeting an ARM processor, the Assembly code will be different than for an x86 processor. Godbolt is a great tool for seeing the Assembly code produced by your C code in realtime as you type it, so you don't have to manually do a compile and objdump (or compile with --save-temps), and you can pretty freely change the target architecture.

I also write for 8-bit PICs, and though there is fairly decent documentation, they've gone through a few assemblers so finding the "right" information is hard. But when I do get something running successfully, oh man do I feel like a clever cookie! But seeing how code is run differently on H8 vs PIC vs AVR vs ARM vs x86-64 really gives you a good understanding of... well, how different architectures run code.

reverse engineering c codegen is great but I learned assembly very quickly after my first computer architecture class as an undergraduate. if you can, go to your nearest state school in a comp sci/eng program. This will really make this process faster. At least see if you can audit an entry to computer architecture class. Once you have a basic understanding of the ISA and pipeline a lot of the magic of cycles/instruction (especially stuff like arm superscalar "magic" with memory fetches) makes a lot of sense.

Assembly is hard to learn because it demands patience and curiosity; the biggest hurdle in asm is . New project == boiler plate console app stub. Side effects of becoming comfortable &| proficient in asm: looking at IML & HLL and asking why does that exist, immediately looking for inline Asm support, looking for CDecl support so you can link asm execs and libs because you can do it in asm easier; looking into Rust frequently because it looks and behaves somewhat like Asm (at least its memory management). Additionally, ref counting and state management aren't as evil as some would like to believe they are simply subject to poor implementation as well as stack & heap becoming less shadow-verse. Good vid btw.

At 11:30, there's a mistake. The STP instruction actually decrements SP _first_ (i.e. pre-increment it by -80 - notice the trailing exclamation mark wrapped on the next line) and then stores the pair of registers at the _new_ location. The LDP in the epilogue does the opposite (i.e. post-increment), it first loads the registers from SP's current location, and then increments it by 80, back to the original value, before returning. Unfortunately pre and post indexing use different syntaxes for whatever reason. Pre-index: STP , , [Address + #offset]! Post-index: STP , , [Address], #offset

I find that it's best to combine this technique with reading the manuals for the processor you're learning about. ARM is a lot harder to look up because they've got so many variants, but there are still plenty of manuals. Learning x86 is significantly easier because the manuals are easier to find and many, many people have written about the subject, plus x86 is just better overall in many ways.

I beg to respectfully differ. "Rosetta Stone" method can be a useful, umm, crutch, but the first step is to understand the underlying processor architecture.

A subtle nuance about calling convention, function prologue and epilogue is that you only care if you want to interact with external code. If you are writing everything from scratch and have very limited interaction with the outside then you are free to be as weird as you want to. Windows programmer have an intuitive understanding of this because there are multiple calling conventions on Windows.

@@vanlepthien6768 Nobody will dispute that in a pragmatic world. However, in a theoretical world, when one is still on an assembly learning journey, it can be valuable to learn that you can do PUSH return_address JMP function instead of CALL in x86/x64 assembly and that the RET instruction will properly follow. Also, it's worthwhile to learn about the 4 (I think) calling conventions supported by MSVC including the differences between x86 and x64 code as this will give you a big insight on how little those conventions actually mean. __vectorcall__ is particularly interesting.

Excellent video! Every programmer should have a working knowledge of assembly for at least one CPU, for very obvious low level concept / knowledge reasons. Every concept of C++, for example, is made much easier the more you know assembly and, crucially, you'll be able to debug...fully and properly !!! - Be VERY careful in making assumptions when looking at the assembly output of any higher level / compiled program !!! ... - ...and irrespective of 'how well' you set the compiler optimisation switches !!! - Understand also, that different compilers very frequently do produce different machine code, no matter how minimal an example you give them !!! - While looking at the assembly output of well-constructed minimal examples certainly can help you along the path of learning assembly, it is, still, orders of magnitude away from how you SHOULD be learning it if you are going to take it to production and eventually expert levels !!! - While some opcodes/operand constructs appear 'simple', they frequently are not, and while other opcodes appear complex, they are. Especially when looking at all the different modes of each opcode !!! For any nations full defence, high expertise in assembly is absolutely crucial. Unfortunately, with such a massive lack in assembly teaching, any country that falls behind is leaving themselves open to a whole lot of pain.

I always try to imagine the concepts in my head, some block of RAM where you assign memory and physically see how many bytes a specific variable takes, for example, or the thing about pointers and addresses. Having videos about Assembly and how everything works at that low level is definitely a must. PS: I don't wanna be that "ackshually" guy, but this thing of visual/auditive/kinetic learners is kind of a myth according to studies, and it's much more complex than that. It turns out that having the same information coming from many different sources at the same time (you being able to see, hear and do the thing at the same time) is much more effective than just receiving the information from a single type of source, and education should focus not in classifying students according to whether they learn more visually, auditively or kinetically, but rather having all of this information from the different types of sources at the same time, complementing and reinforcing itself.

What I did was start designing my own CPUs before I learned any language. So I guess I literally taught myself how to program.

What about x86 assembly?

This is not really relevant to what your trying to teach here but its important to know that in ASM you don't really have a standard return type or maybe even a calling convention. What you show here is the C convention for the C language. But in asm you can kinda do whatever you want. You can return values from a subroutine anyway you want really its just that its not going to be useable by other programs or anything on the system. If you were writing your own OS for example in ASM you could have calling conventions and return types in a different way. Is that usefull.... well no not really its better to follow the standard way to do it but its worth mentioning :P

I tried using that code in godbolt and there's a problem... It doesn't work at all on platform that don't use unix syscalls. So it's completely useless for microcontrollers. Sure you can just delete the line but then it doesn't tell you what to use instead.

learning C++ or C first for getting into game hacking?
@anon_y_mousse
@anon_y_mousse Жыл бұрын
Depends on what kind of hacking you mean. If you just want to write a game, learn both C and C++, but if you want to add features to games you don't have the source code for, or remove annoying features, then you should learn all three, C, C++ and assembly.

@@0x-003 Yeah, that doesn't answer the question. Do you mean writing the game, as the proper and traditional meaning of hacking would imply, or do you mean the modern and incorrect definition that stands in for cracking. If the latter, then yes, learn assembly, too. If the former, then don't bother because it's not necessary for that type of hacking.
