Director

public class X86Director
extends java.lang.Object
implements Director

Provides a representation of directors for x86.

Following is a list of the directors and their representation in this class (which could be used in the form of X86Director.XXX):
.data DATA
.text TEXT
.align ALIGN
.asciz ASCIZ
.globl GLOBL
and so on...

A director is one essential part of a Directive(or what others call "pseudo-instruction"), just like the opcode in an instruction. A director in a directive tell the assembler what to do.
To create a legal Directive using one of the X86 directors, you can refer to the following example:

Directive d = new Directive (X86Director.TEXT, new LinkedList<Directive.Argument>());

In the above example, we created a directive ".text" to explicitly delcare a text segment without any argument. If a directive needs arguments, we can create in the following way:

LinkedList<Directive.Argument> ll = new LinkedList<Directive.Argument>();
Directive.Argument arg = new Directive.Argument(new Integer(4));
ll.add(arg);
Directive d = new Directive(X86Director.ALIGN, arg);


Note: the above example creates an directive just as: ".align 4".
