#### 9.23.5 680x0 Machine Directives

In order to be compatible with the Sun assembler the 680x0 assembler understands the following directives.

`.data1`
  This directive is identical to a `.data 1` directive.

`.data2`
  This directive is identical to a `.data 2` directive.

`.even`
  This directive is a special case of the `.align` directive; it aligns the output to an even byte boundary.

`.skip`
  This directive is identical to a `.space` directive.

`.arch` name
  Select the target architecture and extension features. Valid values for name are the same as for the `-march` command line option. This directive cannot be specified after any instructions have been assembled. If it is given multiple times, or in conjunction with the `-march` option, all uses must be for the same architecture and extension set.

`.cpu` name
  Select the target cpu. Valid valuse for name are the same as for the `-mcpu` command line option. This directive cannot be specified after any instructions have been assembled. If it is given multiple times, or in conjunction with the `-mopt` option, all uses must be for the same cpu.
