C++ abstract machine operation.

\ifcSortSection{NewArray}{TriadicOperator}
Abstract machine operation corresponding to allocating appropriate storage for an array and initializing its elements
if an initializer is present.

When used as the value for the \field{assoc} field of a \sortref{Triad}{ExprSort} structure, that structure
represents the semantic operation for an array \grammar{new-expression}, where
\begin{itemize}
\item the first operand designates the array object type
\item the second operand designates the array bound
\item the third operand designates the initializer, or is null if no initializer is present
\end{itemize}

A null third operand designates absence of an initializer, as in \code{new T[n]}, and is distinct from an empty initializer list.

I don't actually think DyadicOperator::NewArray is used?

It will be soon. I'll update the spec accordingly.


\ifcSortSection{Msvc}{TriadicOperator}
This is a marker, not an actual operator. Triadic operators with
value greater that this are MSVC extensions.
