ZusammenfassungOptimizations in compilers are the most error-prone phases in the
compilation process. Since correct compilers are a vital precondition
for software correctness, it is necessary to prove their
correctness. We develop a formal semantics for static
single assignment (SSA) intermediate representations and prove
formally within the Isabelle/HOL theorem prover that a relatively
simple form of code generation preserves the semantics of the
transformed programs in SSA form. This formal correctness proof does
not only verify the correctness of a certain class of code generation
algorithms but also gives us a sufficient, easily checkable
correctness criterion characterizing correct compilation results
obtained from implementations (compilers) of these algorithms.
