to tell compiler that it is OK for "x" to be uninitialized?
Better to call it "initialized", analogous to attribute used/unused.
I agree.
I think the general idea is reasonable. I also think it might be worth
spending a few minutes thinking about whether we can implement some more
general diagnostic suppression mechanism. E.g.,
int x __attribute__ ((ignore ("-Wuninitialized")));
Or this.
FWIW, I think that's overly ambitious.
There is already an "optimise" function __attribute__ and matching
#pragma's that temporarily change the optimisation flags for a function
(and a similar set for target flags). For warning messages, there are
#pragma's (though no push/pop pragma, AFAIK). Would it be practical to
have a "diagnostic" function __attribute__ in the same style? Then at
least it would be possible to declare
__attribute__((diagnostic("-Wno-uninitialized"))) on the function in
question.
