WebSince 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 the value using (usually) PC-relative addressing, i.e. some offset from r15. Thus, ldr is in fact a pseudo instruction. The following code WebThe ! denotes writeback of the base register.Base register is the register used to address the memory to be read or written - in your case it's R4.Writeback means that the base register will be updated with the delta equal to the size of transferred data..
