Division in arm assembly
If you need a floating-point result you'll need a floating-point division function, which is not easy to implement in software and asm on architectures without FPU. ARMv7 and above have FPU/SIMD by default, some ARMv6 and below also have FPU so you can divide it directly in hardware 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.
