-/// LLVM-typed implementation for generating the implementation for `ndarray.reshape`.
-///
-/// * `x1` - `NDArray` to reshape.
-/// * `shape` - The `shape` parameter used to construct the new `NDArray`.
-///   Just like numpy, the `shape` argument can be:
-///   1. A list of `int32`;   e.g., `np.reshape(arr, [600, -1, 3])`
-///   2. A tuple of `int32`;  e.g., `np.reshape(arr, (-1, 800, 3))`
-///   3. A scalar `int32`;     e.g., `np.reshape(arr, 3)`
-///
-/// Note that unlike other generating functions, one of the dimensions in the shape can be negative.

-// Uses `nalgebra` crate to invoke `np_linalg` and `sp_linalg` functions
-// When converting between `nalgebra::Matrix` and `NDArray` following considerations are necessary
-//
-// * Both `nalgebra::Matrix` and `NDArray` require their content to be stored in row-major order
-// * `NDArray` data pointer can be directly read and converted to `nalgebra::Matrix` (row and column number must be known)
-// * `nalgebra::Matrix::as_slice` returns the content of matrix in column-major order and initial data needs to be transposed before storing it in `NDArray` data pointer
