Abstract
In my PhD thesis I have developed a formal semantics of a significant
part of the C programming language as described by the C11 standard.
In this talk I will give a brief overview of the main parts of my
formalized semantics.

* A structured memory model based on trees to capture subtleties of
C11 that have not been addressed by others.

* A core C language with a small step operational semantics. The
operational semantics is non-deterministic due to unspecified
expression evaluation order.

* An explicit type system for the core language that enjoys type
preservation and progress.

* A type sound translation of actual C programs into the core language.

* An executable semantics that has been proven sound and complete with
respect to the operational semantics.

* Extensions of separation logic to reason about subtle constructs in
C like non-determinism in expressions, and gotos in the presence of
block scope variables.
