23 Controls whether to utilize the ARM Thumb instruction set or not.
24 Thumb is an extension to the 32-bit ARM architecture. It features
25 a subset of the most commonly used 32-bit ARM instructions which
26 have been compressed into 16-bit wide opcodes. On execution, these
27 16-bit instructions are decompressed transparently to full 32-bit
28 ARM instructions in real time without performance loss.
29 The use of the Thumb extension usually increases code density,
