Another important nuance is the distinction between the ARM and Thumb (T32) instruction sets. The ARM32 architecture supports both. However, the --arm_only flag in ARM compilers forces the generation of pure A32 code, prohibiting any Thumb (T32) code. This ensures that the entire image is composed only of the standard 32-bit ARM instructions, which can be crucial for compatibility or performance in certain embedded applications.
