+    Load a cooperative matrix through a pointer.
+
+    Result Type is the type of the loaded object. It must be a cooperative
+    matrix type.
+
+    Pointer is a pointer into an array. Its type must be an OpTypePointer whose
+    Type operand is a scalar or vector type. The storage class of Pointer must
+    be Workgroup, StorageBuffer, or (if SPV_EXT_physical_storage_buffer is
+    supported) PhysicalStorageBufferEXT.
+
+    Stride is the number of elements in the array in memory between the first
+    component of consecutive rows (or columns) in the result. It must be a
+    scalar integer type.
+
+    ColumnMajor indicates whether the values loaded from memory are arranged in
+    column-major or row-major order. It must be a boolean constant instruction,
+    with false indicating row major and true indicating column major.
+
+    Memory Access must be a Memory Access literal. If not present, it is the
+    same as specifying None.
+
+    If ColumnMajor is false, then elements (row,*) of the result are taken in
+    order from contiguous locations starting at Pointer[row*Stride]. If
+    ColumnMajor is true, then elements (*,col) of the result are taken in order
+    from contiguous locations starting from Pointer[col*Stride]. Any ArrayStride
+    decoration on Pointer is ignored.
+
+    For a given dynamic instance of this instruction, all operands of this
+    instruction must be the same for all invocations in a given scope instance
+    (where the scope is the scope the cooperative matrix type was created with).
+    All invocations in a given scope instance must be active or all must be
+    inactive.
