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.

@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"}.
