Add with carry problem

[DSS]

Hi all,

I was writtng pattern for add with carry operation in md file. But at one
point i got stuck.

Problem is that I know there is CC mode for status register in GCC, but
i don't know how to specify mode for a particular bit of the status
register. Like for Carry bit only i want to specify the mode. How to do
that. Please help me in this.

I have written 'CC_MODE (CC_C);' in machine-modes.def file. And defined
SELECT_CC_MODE macro in '.h' file also. But still error is undefined CC_C
mode. I am using gcc-4.3.0.

Regards,
Rajiv Kumar
