Modern multiprocessors architectures and programming languages exhibit weakly consistent memories. Their behaviour is formalised by the memory model of the architecture or programming language; it precisely defines which write operation can be returned by each shared memory read. This is not always the latest store to the same variable, because of optimisations in the processors such as speculative execution of instructions, the complex effects of caches, and optimisations in the compilers. In this thesis we focus on the C11 memory model that is defined by the 2011 edition of the C standard. Our contributions are threefold. First, we focused on the theory surrounding the C11 model, formally studying which compiler optimisations it enables. ...
