- <p>The D30V 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.
- </p>
- <p>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.
