``__builtin_allow_runtime_check`` return true if the check at the current program location should be executed.

**Syntax**:
3473+
3474+
.. code-block:: c++
3475+
3476+
bool __builtin_allow_runtime_check(const char* kind)
3477+

**Example of use**:

.. code-block:: c++
3481+
3482+
if (__builtin_allow_runtime_check("mycheck") && !ExpensiveCheck()) {

**Description**
3487+
3488+
``__builtin_allow_runtime_check`` is lowered to ` ``llvm.allow.runtime.check`` <https://llvm.org/docs/LangRef.html#llvm-allow-runtime-check-intrinsic>`_ builtin.
3489+
3490+
The ``__builtin_allow_runtime_check()`` builtin is typically used with control flow
3491+
conditions such as in ``if`` to guard expensive runtime checks. The specific rules for selecting permitted checks can differ and are controlled by the compiler options.
3492+
