+# TritonAST to LLVM-IR and back
+
+This code has been developed as a quick test in a weekend to evaluate how feasible it would have been to use LLVM-IR optimizations to simplify a TritonAST.
+
+The steps are:
+
+1. getting an **unrolled** TritonAST;
+2. convert it to LLVM-IR via the **TritonAstToLLVMIR** function;
+3. get the **simplified** TritonAST as output with the **LLVMIRToTritonAst** function.
+
+# TODO
+
+1. Provide a C++ example showing the described steps.
+2. Verify the consistency of all the translations.
