LOGICAL AND OPERATOR EARLY OUT EXAMPLE

Given the following segment of XCASM source code:

	xif  A == B  &&  G == H  xthen  .let A = A + 1

The hand crafted "early out" equivalent would be:

	xif  A != B  xthen  goto xif_false_0
	xif  G != H  xthen  goto xif_false_0

	.let A = A + 1

xif_false_0

The compiler actually generates the following assembler source code for the above segment:

                                ;;;-------------------
                                ;;;   xif   A == B && G == H 
                                ;;;   xthen .let A = A + 1 
                                ;;;-------------------
