you can learn assembly FAST with this technique (arm64 breakdown) 

First!

Everything is open source if you know assembly.

The "Turing Complete" game is a great way of learning assembly imo. It made me realised that assembly is just a readable form of machine code, sending a pattern of electric signals to open/close transistors inside the ALU.

Assembly was so beautiful, elegant and intuitive in the 8bit era

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.

Like all really good ideas, I've never thought of it ever in my life. And then, when I'm shown, I say "Oh yeah... but that's just obvious!" GREAT STUFF!

Always excited to see educational material for understanding Assembler.

This was so obvious yet still blew my mind. Thank you

Ah beautiful, I was really looking for a resource to learn but I could not find anything reasonable. Thanks man!

I have a hard time believing that this is the best strategy for learning your first assembly language. But I can see this very much being helpful at taking up another assembly language after you learned another first. Without that, to my knowledge, you'll usually have to go through a lot of documentation that's not easy to search through nor to understand in terms of the concepts we programmers use more commonly.

I started learning Assembly in 2017; and I kind of like it and hate it at the same time. But I can't seem to be able to walk away from it. I would love to see more videos. Thank You!

Amazing!! More assembly please 😍

I use Godbolt every time I want to know how C code complies to ARM assembly. It also supports other languages, too. I recommend playing with it.

Love your videos 👏👏👏

I appreciated the fish break.

Less than a minute in, and YES YES YES. I've been trying to write some assembly for a Hitachi H8/520 recently, and it's... hard. 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.

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]

hi low level learning, must say u make some amazing vids and really help me learn new concepts.

Hey man can you make an x86 assembly beginner course? I'd absolutely *love* learning assembly from you!

simply brilliant

thank you 👍

Fantastic

Assembly makes sense 🧠⚡️

You're absolutely right. I returned to C after learning 80x86 assembler and I was so much better and understood what was going on at a much deeper level. Incidentally, I learnt the small amount of ARM assembly that I needed for my job from doing exactly what you did here, writing some C code and examining the generated ASM code.

The video-game TIS-1000 helped me so much

The first time Ilearnt assembly, i used that method by compiling c code with gcc and then use the disassemble of gdb (I was 16 at the time and didn't know of objdump). It helped me a lot even though right now I prefer something more straightforward like the wikipedia page on calling conventions or pages with the list of registers and all.

This one learned assembly the hard way. Starting at 16 bit DOS programming, switching to 32 Bit x86 architecture and then after years and after 64bit became popular learned 64bit ASM. I feel like I know nothing tbh.

It's always a good idea to bookmark the ABI.

kindly make a full course on assembly language.

Fish break, fish continue, fish return

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.

I really need something like this, coding in asm feels like a hacker 😎😎 But honestly I want to learn asm for disassembling. Thanks a lot!

Another item learned is the size of each instruction (4 bytes). This is why that first load of x0 with 0xbabecafef00dface was done in 4 instructions instead of just 1. 👍

Good idea.

this is very interesting.

Please make more for other instructions sets

Can you make a video on how to setup assembly language on a machine. Like the assembler, VS code extensions or other setup things

Just , Wow🤩🤯

Hey kinda off topic question but at 8:37 can you remove the instruction at location 40074c? why would you store the contents of the w0 register to the stack and load it back from the stack to the same register immediately after?

10:49 this actually taught me everything I need to talk with friends and family. By family I mean chipset family, and by friends I mean my debugging duck.

Nice to see a fellow i3 enthusiast 😁😁

I still have my 16 bit NASM books at my old house.

your merch store is not working. Says page is missing. Fascinating stuff btw. I feel a great attraction towards lower level programming in C and assembly in general and reverse engineering seems like a fantastic hobby! Can't wait to get into it head first!

something i found recently to learn more about sys prog was to follow Andreas Kling writing his serenity OS from scratch.

I learned fast that I cannot learn assembly fast

You can make more videos about this topic ! Precius content!

Also keep up the good work

shouts out to my boy Creel, I've watched so much of his content to learn x86 basics

Also java compiled class files uses cafe babe as first 2 hex binary

ARM assembly syntax is so much cleaner than x64 wow

now to do this and finally learn how to code

I want to learn some low level stuff with a hope one day I can contribute to Free Pascal. My favorite compiler in za world.

Was the long long in the main function (0xbabecafef00dface) some weird reference somehow to the magic number at the beginning of a Java class file 0xCAFEBABE?

Although I come from Java and JavaScript, neither of which involves managing memory, I'll need to watch this video multiple times to grasp it. I'll use RU-vid's save feature to come back to it.

Wow lol wow thats a nice technique

Nintendo assembly is fun to learn and theres lot of examples, its a great way to learn if you're not motivated easily but are an old man and like Nintendo like me.

Do ARM CPUs have different states like x86 CPUs like 16, 32 and 64 bit modes?

Hello thanks for this toturial Actually I need use GPU by assembly language but I don't know how do that There is any video toturial to learning???

Who else can’t get an internship so you’re learning assembly over the summer???

When you dropping the first video for your upcoming Zero to Hero C programming course?

The real gigachad move is to reverse engineer the compiler

What OS and desktop environment do you use ?

Can you do a video on intel assembly too?

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.

L3 going back to talking about ASM is like MTV going back to playing music video. HALLELUJER !!

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.

Imagine having rust as your fav language assembly is for the pros

I didn't write, but looking at it was always cool

looking levels of optimization higher that 0 is more helpful in understanding what normal code should look like.

yeah but how do i async await and install npm packages in assembly?

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. For starters, just basics: register file structure, addressing modes, procedure call conventions, interrupt system. Exotics such as block moves, vector instructions etc may come later.

I studied assembler in college and have a basic understanding of it, so I wanted to revisit the topic. I found this video, but it’s extremely confusing. I can't imagine that someone new to assembler would find it helpful; it just seems like gibberish.

Wouldn't this be "easier" by using godbolt? (local instance or otherwise?)

4:07 Fish break!

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.

I have a list of programming languages and concepts to learn, but your videos make me wanna add assembly to that list. For my purposes I still need to prioritize other stuff but I'll get to play with it at some point. I failed assembly back in engineering school (ca. 2010), mainly because I kinda gave up on the whole semester back then, but I still remember how frustrating the way they tried to teach it to us was 😓

I use a C++ compiler from embarcadero, they allow inline assembly, But the AT&T variant, kind of tricky to me

Ah yes ASM brings me back to my virr days of coding.

One of the best designed and easiest assembly languages from history was Datacraft (later harris)

What about x86 assembly?

can u tell us your setup

babecafefoodface was very confusing... Lol

Hello Sirs :D

does this work for llvm ir ?

You and John Hammond look so similar, if you are not him, you have to be his brother.

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.

BR 14 Who needs a stack architecture? :)

boy id love to go the the babe cafe and get some food into my face

i’m too busy taking photos of my brunch at babe cafe food face to learn assembly

Transcompile assembley and Python pls

But how to do this on Windows?

There should be a video with technics of how you can optimise the code with ASM. Like loop unroling and etc.

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.

Rather then learning by inference, why not just read the damn assembly language manual? That has worked well for the last 15 processors I've coded in assembly. Your technique doesn't do much for learning how the flags work, the special purpose register usage (if there is any), how the interrupts work, etc.

0:15 "Assembly is hard to learn" - No - assembler is very easy, hard to understand is exactly C and other variations like Cpp - so many combinations with any typecasting, pointer what I have in assembler immediatelly in 2 max 3 codelines.

learning C++ or C first for getting into game hacking?

All I hear is “babe cafe food face value”

If we could have a full tutorial with episodes from you that would be awesome, be it C or assembly

Assembly is the language that rules them all lol
