Finds code that opens file without using the O_CLOEXEC flag.
open(), openat(), and open64() had better to include O_CLOEXEC in their flags argument. Only consider simple cases that the corresponding argument is constant or binary operation OR among constants like 'O_CLOEXEC' or 'O_CLOEXEC | O_RDONLY'. No constant propagation is performed.
Only the symbolic 'O_CLOEXEC' macro definition is checked, not the concrete value.

Override this to register AST matchers with Finder
.
This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.
You can register as many matchers as necessary with Finder
. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.
If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.
