Hi,

I am trying to debug some code and I came through "bne.n and "b.n" and
"bmi.n" like ARM assembly instructions.

I was able to find what "bne", "b", and "bmi" instruction does.... But
I am not able to understand what ".n" at the end of each instruction
means ?

I am little bit new to ARM assembly...

The .n suffix is used in ARM UAL Thumb-2 assembly where you have a
choice of instruction encodings: 16- or 32-bit. It forces a 16-bit
encoding to be used.

Regards,
Dave
