28 The PowerPC chip family includes several successive levels, using the same
29 core instruction set, but including a few additional instructions at
30 each level. There are exceptions to this however. For details on what
31 instructions each variant supports, please see the chip's architecture

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