================
Comment at: clang/lib/StaticAnalyzer/Checkers/ErrnoChecker.cpp:47
+ /// Indicates if a read (load) of \c errno is allowed in a non-condition part
+ /// of \c if, \c switch, loop and conditional statements when the errno
+ /// value may be undefined.
----------------
You prefixed the previous two keywords with the `\c` marker. Why is it missing from the `switch`?
================
Comment at: clang/lib/StaticAnalyzer/Checkers/ErrnoChecker.cpp:100
+ case Expr::BinaryConditionalOperatorClass:
+ CondFound = (S == cast<BinaryConditionalOperator>(ParentS)->getCommon());
+ break;
----------------
Oh, so the test added for this actually uncovered a bug?
