NettetARM uses a load-store model for memory access which means that only load/store (LDR and STR) instructions can access memory. While on x86 most instructions are allowed to directly operate on data in memory, on ARM data must be moved from memory into registers before being operated on. http://www.mztn.org/dragon/arm6405str.html

NettetLDR loads a 32-bit constant (LDRH (halfword): 16 bit, LDRB (byte): 8 bit) from memory into the specified target register (r0 in your example). Since 32-bit constants cannot be encoded in 32-bit opcodes (or 16-bit for Thumb instructions), the assembler stores the constant in the text segment close to the referencing instruction and then references …
