In Thumb1, legal imm range is [0, 255] for ADD/SUB instructions. However, the legal imm range for LD/ST in (R+Imm) addressing mode is [0, 127]. Imms in [128, 255] are materialized by mov R, #imm, and LD/STs use them in (R+R) addressing mode. This patch checks if a constant is used as offset in (R+Imm), if so, it checks isLegalAddressingMode passing the constant value as BaseOffset.
