I do have a couple of asserts in my code, but that does not explain why every stack trace begins and ends with "assert()" Actually I call syscalls from assembly, and my _start() is also an assembly function. That is why this happe

Yeah, you are right. Android is a variant of Linux. Just like MacOS and iPadOS, both run Darwin kernel, but they are very different. Even though iPads have very capable hardware, there are a lot you cannot do on iPadOS. The same applies to

> It's easy enough to learn "base + index*scale +- displacement". Well, you already know this requirement, so it is not a problem for you. However for learners, who don't have even the remotest idea of machine instruc

It can be useful I think. Trying this on my toy project. This is a single thread program so it cannot do syscall from multiple cores. It is not very helpful without debug info: nanosleep({tv_sec=1, tv_nsec=299127292}, NULL) = 0 >

I love AT&T syntax. I originally started with Intel syntax when learning assembly since it was just in my textbook. I sometimes ran into weird syntax issues I didn't yet understand. For example, why "mov eax, [ebx + 2 * ecx +
