WebMay 10, 2014 · The assembly source code is specific to the computer architecture, in RPi's case, ARM. GNU's gcc (the most common compiler you use for compiling C source codes in Linux) has also the assembler that will get an assembly source code and generate the executable machine code from it. Coding in assembly is very hard and not something to … WebAug 22, 2024 · This provides a somewhat welcome change from older architectures where syscalls are all wildly different (for example, exit is 1 in ARM EABI and x86, but 60 in x86-64). From unistd.h we can see that write is number 64 and exit is number 93. To assembly. Our ARM64 assembly listing, hello.S, therefore looks like (see inline comments for details):
