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"}.

@subsection Special Characters
|
|
|
|
@cindex line comment character, PowerPC
|
|
@cindex PowerPC line comment character
|
|
The presence of a @samp{#} on a line indicates the start of a comment
|
|
that extends to the end of the current line.
|
|
|
|
If a @samp{#} appears as the first character of a line then the whole
|
|
line is treated as a comment, but in this case the line could also be
|
|
a logical line number directive (@pxref{Comments}) or a preprocessor
|
|
control command (@pxref{Preprocessing}).
|
|
|
|
If the assembler has been configured for the ppc-*-solaris* target
|
|
then the @samp{!} character also acts as a line comment character.
|
|
This can be disabled via the @option{-mno-solaris} command line
|
|
option.
|
|
|
|
@cindex line separator, PowerPC
|
|
@cindex statement separator, PowerPC
|
|
@cindex PowerPC line separator
|
|
The @samp{;} character can be used to separate statements on the same
|
|
line.
