"Coccinelle is a program matching and transformation engine which provides the language SmPL (Semantic Patch Language) for specifying desired matches and transformations in C code. Coccinelle was initially targeted towards performing collateral evolutions in Linux. Such evolutions comprise the changes that are needed in client code in response to evolutions in library APIs, and may include modifications such as renaming a function, adding a function argument whose value is somehow context-dependent, and reorganizing a data structure. Beyond collateral evolutions, Coccinelle is successfully used (by us and others) for finding and fixing bugs in systems code." (http://coccinelle.lip6.fr/)

This training introduces the Coccinelle semantic matching engine for C programs.

Target audience are medium to advanced C programmers interested in restructuring large scale programs.

Applications in HPC will be mentioned, examples will be given.

Tentative program:

  • Invoking Coccinelle.
  • Semantic matching.
  • Semantic patching.
  • Elements of the SmPL language.
  • Simple SmPL rules.
  • Rules with inheritance.
  • Reusing rules.
  • Scripting.
  • Review of common transformations and use cases in HPC.
  • Hands-on exercises.

Contents are subject to modifications.
