+@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}
