The direct predecessor of SLEIGH was an implementation of SLED for
GHIDRA, which concentrated on its reverse-engineering
capabilities. The main addition of SLEIGH is the ability to provide
semantic descriptions of instructions for data-flow and
decompilation analysis. This piece of SLEIGH was originally a
separate language, the Semantic Syntax Language (SSL), very loosely
based on concepts and a language of the same name developed by
Cristina Cifuentes, Mike Van Emmerik and Norman Ramsey, for the
University of Queensland Binary Translator (UQBT) project.
semantic descriptions of instructions for data-flow and decompilation
analysis. This piece of SLEIGH borrowed ideas from the Semantic Syntax Language (SSL),
a specification language developed in <a class="xref" href="sleigh.html#Cifuentes00">[2]</a> for the
University of Queensland Binary Translator (UQBT) project by
Cristina Cifuentes, Mike Van Emmerik and Norman Ramsey.

Dr. Cristina Cifuentes' work, in general, was an important starting point for the GHIDRA decompiler.
Its design follows the basic structure layed out in her 1994 thesis "Reverse Compilation Techniques":
</p>
<div class="informalexample"><div class="itemizedlist"><ul class="itemizedlist compact" style="list-style-type: bullet; ">
<li class="listitem" style="list-style-type: disc">
Disassembly of machine instructions and translation to an intermediate representation (IR).
</li>
<li class="listitem" style="list-style-type: disc">
Transformation toward a high-level representation via
<div class="itemizedlist"><ul class="itemizedlist compact" style="list-style-type: circle; ">
<li class="listitem" style="list-style-type: circle">
Data-flow analysis, including dead code analysis and copy propagation.
</li>
<li class="listitem" style="list-style-type: circle">
Control-flow analysis using graph reducibility to achieve a structured representation.
</li>
</ul></div>
</li>
<li class="listitem" style="list-style-type: disc">
Back-end code generation from the transformed representation.
</li>
</ul></div></div>
<p>
In keeping with her philosophy of decompilation, SLEIGH is GHIDRA's implementation of the first step.
It efficiently couples disassembly of machine instructions with the initial translation into an IR.
