Part 4/10:
A primary step in mastering any assembly language is understanding the registers involved. Registers serve as the CPU's high-speed memory where data is temporarily stored during operations. By compiling the provided C code and object dumping the output, one can observe how various data types are handled in ARM 64-bit assembly.
For instance, when the author analyzes the assembly output, they discover that a 64-bit value is stored in the register x0, while a 32-bit value is managed by w0. Understanding these conventions allows learners to clearly delineate between the different register sizes and helps in contextualizing how data is shifted between them.
