 // The RawMachineAssembler produces a low-level IR graph. All nodes are wired
 // into a graph and also placed into a schedule immediately, hence subsequent
 // code generation can happen without the need for scheduling.
 //
 // In order to create a schedule on-the-fly, the assembler keeps track of basic
 // blocks by having one current basic block being populated and by referencing
 // other basic blocks through the use of labels.
+//
+// Also note that the generated graph is only valid together with the generated
+// schedule, using one without the other is invalid as the graph is inherently
+// non-schedulable due to missing control and effect dependencies.
