IBM PowerPC 405GP User Manual

Table 3-25 lists additional arithmetic instructions for multiply-accumulate and multiply halfword
operations.
In the table, the syntax "[0]" indicates that an instruction has an "0" form that updates
XER[SO,OV], and a "non-o" form. The syntax "[.]" indicates that the instruction has a "record" form
that updates
CR[CRO], and a "non-record" form.
