1 9.9.2.2 Sub-Instructions
1 ........................
1 
1 The D10V assembler takes as input a series of instructions, either
1 one-per-line, or in the special two-per-line format described in the
1 next section.  Some of these instructions will be short-form or
1 sub-instructions.  These sub-instructions can be packed into a single
1 instruction.  The assembler will do this automatically.  It will also
1 detect when it should not pack instructions.  For example, when a label
1 is defined, the next instruction will never be packaged with the
1 previous one.  Whenever a branch and link instruction is called, it will
1 not be packaged with the next instruction so the return address will be
1 valid.  Nops are automatically inserted when necessary.
1 
1    If you do not want the assembler automatically making these
1 decisions, you can control the packaging and execution type (parallel or
1 sequential) with the special execution symbols described in the next
1 section.
