WebLDR 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 the value using … Web16 ott 2024 · An important point is that ARM doesn't deal with 8 or 16 bits in registers (like ah, al or ax in x86) and always uses 32 bit constants.
