If you write:

        AREA x,CODE
        THUMB
        MOVNE   r0,r1 ; (1)
        NOP
        IT      NE
        MOVNE   r0,r1 ; (2)
        END

the assembler generates an IT instruction before the first MOVNE instruction.

You can get warning messages about this automatic generation of IT blocks when assembling Thumb code. To do this, use the following command-line option when invoking the assembler:

armasm --diag_warning 1763
