◆ Kind
Specifies which kind of type check we should emit for this byte array.
See http://clang.llvm.org/docs/ControlFlowIntegrityDesign.html for full details on each kind of check; the enumerators are described with reference to that document.
| Enumerator | |
|---|---|
| Unsat | Unsatisfiable type (i.e. no global has this type metadata) |
| ByteArray | Test a byte array (first example) |
| Inline | Inlined bit vector ("Short Inline Bit Vectors") |
| Single | Single element (last example in "Short Inline Bit Vectors") |
| AllOnes | All-ones bit vector ("Eliminating Bit Vector Checks for All-Ones Bit Vectors") |
| Unknown | Unknown (analysis not performed, don't lower) |
