The PowerPC chip family includes several successive levels, using the same
core instruction set, but including a few additional instructions at
each level. There are exceptions to this however. For details on what
instructions each variant supports, please see the chip's architecture
reference manual.
The following table lists all available PowerPC options.

@cindex PowerPC directives
A number of assembler directives are available for PowerPC. The
following table is far from complete.
@table @code
@item .machine "string"
This directive allows you to change the machine for which code is
generated. @code{"string"} may be any of the -m cpu selection options
(without the -m) enclosed in double quotes, @code{"push"}, or
@code{"pop"}. @code{.machine "push"} saves the currently selected
cpu, which may be restored with @code{.machine "pop"}.
