WitrynaSince 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 … WitrynaImmediate addressing mode means that the value for a given instruction in assembly programming is directly specified. This means the value is constant and written immediately and immutably into the instruction. Video of the Day Common Format of Immediate Addressing
