+The D10V assembler takes as input a series of instructions, either one-per-line,
+or in the special two-per-line format described in the next section.  Some of these
+instructions will be short-form or sub-instructions.  These sub-instructions can be packed
+into a single instruction.  The assembler will do this automatically.  It will also detect
+when it should not pack instructions.  For example, when a label is defined, the next
+instruction will never be packaged with the previous one.  Whenever a branch and link
+instruction is called, it will not be packaged with the next instruction so the return
+address will be valid.  Nops are automatically inserted when necessary.
+
+If you do not want the assembler automatically making these decisions, you can control
+the packaging and execution type (parallel or sequential) with the special execution 
+symbols described in the next section.
