The compilation of a program from an object/source language to linkable or executable target code is generally accompanied by transformation processes. The generic tools or components of environments which accomplish this phased restructuring as a semantic aspect of program generation or for the sake of program optimization, are included in this subcategory.
Submissions should include generic tools or specific components of systems which perform transformations during the compilation process via characteristic methods. Compiler-specific transformations pertinent only within a certain implementation of a programming language should be appropriately classified elsewhere under a subcategory for that programming language.
