--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> ---
"=@ccc"(r) does not output to the "cc" register, it outputs to a general
register. It clobbers the "cc" register. Mentioning that more than
once ("=@ccc", the clobber in the asm, and it is default for the x86
target) is no problem and has clear semantics.
The "cc" clobber is not deprecated, not on other targets anyway.
Even on x86 it still serves to mark those asms that really clobber
the flags register, which can be helpful to the reader.
