Hi All!
I have converted the AVR port from CC0 to CCmode.
But may be I have converted the port in wrong way.
(It's because I was interested in *this* way.)
I have used CCmode register and havn't added the
'(clobber (reg:QI CC_REGNUM))' to any insn that really clobber the
CC_REGNUM just because AVR is'n needed in scheduling.
I think that sequence of compare + cond-jump will exists in any
compiler pass.
The port was successfully tested without new regressions.
What do you (MAINTAINERS) think about this ?
Denis.
