Source-Code Migration Using Decompilation

Abstract

This thesis deals with source-code migration of high-level programming languages using decompilation. A migration tool developed within the thesis is built on top of the middle-end and back-end parts of Lissom project decompiler. Several compilers generating LLVM IR code from input languages are discussed. Compilers suitable for integration to the migration tool were chosen. Compiled LLVM IR code is an input of the decompiler's optimizing middle-end. The output from the migration tool is a code in the C language or Python-like language generated by the back-end of the decompiler. The input languages are Fortran and its dialects, C/C++/Objective-C/Objective-C++, and D. The thesis describes problems connected with migration of these languages, their solutions, and ways to improve quality and readability of the produced source code.
