Detailed Description

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.
