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 … WebJun 9, 2024 · The ARM processor (Thumb-2), part 8: Bit shifting and bitfield access - The Old New Thing The ARM processor (Thumb-2), part 8: Bit shifting and bitfield access Raymond Chen June 9th, 2024 4 0 The ARM processor shows off its barrel shifter once again in its collection of bit shifting instructions.
