 ### Sample
 
+You can search for missing optimizaitons patterns for example
+
+```SQL
+-- trunc (binop (Y, (ext X))) --> binop ((trunc Y), X)
+SELECT instruction AS "Missing Optimization: trunc (binop (Y, (ext X))) --> binop ((trunc Y), X)"
+FROM instructions WHERE m_inst(instruction, m_trunc(m_binop(m_any_inst(), m_zext() || m_sext())));

+-- trunc (binop (ext X), Y) --> binop X, (trunc Y)
+SELECT instruction AS "Missing Optimization: trunc (binop (ext X), Y) --> binop X, (trunc Y)"
+FROM instructions WHERE m_inst(instruction, m_trunc(m_binop(m_zext() || m_sext())));
+```

 If we have LLVM IR function like this, and we want to match `add` instruction that has result of sub instruction as Left hand side and result of mul instruction as Right hand side.
