Prazek added a comment.
So the testing on llvm shows mostly one case - using DEBUG macro like this:
/home/prazek/llvm/lib/Support/APInt.cpp:1656:9: warning: implicitly converting
integer literal to bool inside macro, use bool literal instead
[modernize-use-bool-literals]
DEBUG(dbgs() << " " << r[i]);
^
/home/prazek/llvm/include/llvm/Support/Debug.h:92:18: note: expanded from macro
'DEBUG'
#define DEBUG(X) DEBUG_WITH_TYPE(DEBUG_TYPE, X)
^
/home/prazek/llvm/include/llvm/Support/Debug.h:69:48: note: expanded from macro
'DEBUG_WITH_TYPE'
#define DEBUG_WITH_TYPE(TYPE, X) do { } while (0)
^
Some programers maybe would like to supress this in the case of expressions
like while(1), or specially when it is inside macro.
What do you think guys? Should we add some special option like
supress-for-while or supress-macro-while?
