@cindex MicroBlaze architectures
|
|
The Xilinx MicroBlaze processor family includes several variants, all using
|
|
the same core instruction set. This chapter covers features of the @sc{gnu}
|
|
assembler that are specific to the MicroBlaze architecture. For details about
|
|
the MicroBlaze instruction set, please see the @cite{MicroBlaze Processor
|
|
Reference Guide (UG081)} available at www.xilinx.com.

@cindex MicroBlaze directives
|
|
A number of assembler directives are available for MicroBlaze.
|
|
|
|
@table @code
|
|
@item .data8 @var{expression},...
|
|
This directive is an alias for @code{.byte}. Each expression is assembled
|
|
into an eight-bit value.
|
|
|
|
@item .data16 @var{expression},...
|
|
This directive is an alias for @code{.hword}. Each expression is assembled
|
|
into an 16-bit value.
|
|
|
|
@item .data32 @var{expression},...
|
|
This directive is an alias for @code{.word}. Each expression is assembled
|
|
into an 32-bit value.
|
|
|
|
@item .ent @var{name}[,@var{label}]
|
|
This directive is an alias for @code{.func} denoting the start of function
|
|
@var{name} at (optional) @var{label}.
|
|
|
|
@item .end @var{name}[,@var{label}]
|
|
This directive is an alias for @code{.endfunc} denoting the end of function
|
|
@var{name}.
|
|
|
|
@item .gpword @var{label},...
|
|
This directive is an alias for @code{.rva}. The resolved address of @var{label}
|
|
is stored in the data section.
|
|
|
|
@item .weakext @var{label}
|
|
Declare that @var{label} is a weak external symbol.
|
|
|
|
@item .rodata
|
|
Switch to .rodata section. Equivalent to @code{.section .rodata}
|
|
|
|
@item .sdata2
|
|
Switch to .sdata2 section. Equivalent to @code{.section .sdata2}
|
|
|
|
@item .sdata
|
|
Switch to .sdata section. Equivalent to @code{.section .sdata}
|
|
|
|
@item .bss
|
|
Switch to .bss section. Equivalent to @code{.section .bss}
|
|
|
|
@item .sbss
|
|
Switch to .sbss section. Equivalent to @code{.section .sbss}
|

@subsection Special Characters
|
|
|
|
@cindex line comment character, MicroBlaze
|
|
@cindex MicroBlaze 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, the whole line
|
|
is treated as a comment, but in this case the line can also be a
|
|
logical line number directive (@pxref{Comments}) or a
|
|
preprocessor control command (@pxref{Preprocessing}).
|
|
|
|
@cindex line separator, MicroBlaze
|
|
@cindex statement separator, MicroBlaze
|
|
@cindex MicroBlaze line separator
|
|
The @samp{;} character can be used to separate statements on the same
|
|
line.
