 * Functions that are used as markers in Gecko code for static analysis. Their
 * purpose is to have different AST nodes generated during compile time and to
 * match them based on different checkers implemented in build/clang-plugin


#ifdef __cplusplus
 * MOZ_KnownLive - used to opt an argument out of the CanRunScript checker so
 * that we don't check it if is a strong ref.
 * Example:
 * canRunScript(MOZ_KnownLive(rawPointer));
template <typename T>
static MOZ_ALWAYS_INLINE T* MOZ_KnownLive(T* ptr) {
  return ptr;

 * Ditto, but for references.
template <typename T>
static MOZ_ALWAYS_INLINE T& MOZ_KnownLive(T& ref) {
  return ref;


 * MOZ_AssertAssignmentTest - used in MOZ_ASSERT in order to test the possible
 * presence of assignment instead of logical comparisons.
 * Example:
 * MOZ_ASSERT(retVal = true);
static MOZ_ALWAYS_INLINE MOZ_CONSTEXPR bool MOZ_AssertAssignmentTest(
    bool exprResult) {
  return exprResult;
