    thumb-2 instruction (which mixes 32bit instruction and 16bit instruction).[/size][/font][/color][color=#222222][font=arial, helvetica, sans-serif][size=2]

    [color=#222222][font=arial, helvetica, sans-serif][size=2]Just to be clear - if the CPU you are compiling for supports the Thumb2 instructions then they will be generated if you specify -mthumb.[/size][/font][/color]
