2.4 Assembler Error Messages

Messages generated by the assembler are generally self-explanatory and give sufficient information to allow correction of a problem.

Certain conditions will cause the assembler to issue warnings associated with delay slots following Control Transfer Instructions (CTI). These warnings are:

These warnings point to places where a problem could exist. If you have intentionally written code this way, you can insert an .empty pseudo-operation immediately after the control transfer instruction.

The .empty pseudo-operation in a delay slot tells the assembler that the delay slot can be empty or can contain whatever follows because you have verified that either the code is correct or the content of the delay slot does not matter.
