Hello all,

Will it be possible to write a pattern in the md file to support
setting/clearing a bit of a particular register?
The instructions are as follows:

clrb Rx, bitNo
setb Rx, bitNo

Could you point me to the back-ends that has support for this kind of
instructions?

Thanks for your time.

Regards,
Shafi.
