9 AltiVec Simplified Mnemonics
Simplified mnemonics are provided for the Data Stream Stop (dss) instruction so that it can be coded with
the all streams indicator as part of the mnemonic. These are shown as examples with the instructions in
Table 29.
Simplified mnemonics for two vector instructions are also supported, as shown in Table 30.
