Tables 119 through 126 contain the instructions belonging to each group and the number
of operands required for each instruction. Some instructions appear in more than one table
as these instruction can be considered as a subset of more than one category. Within these
tables, the source operand is identified as ’src’, the destination operand is ’dst’ and a con-
dition code is ’cc’.
