1 9.10.2.2 Sub-Instructions
1 .........................
1
1 The D30V 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 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.
