A Program Logic for C11 Memory Fences
We describe a simple, but powerful, program logic for reasoning about C11 relaxed accesses used in conjunction with release and acquire memory fences. Our logic, called fenced separation logic (FSL), extends relaxed separation logic with special modalities for describing state that has to be protected by memory fences. Like its precursor, FSL allows ownership transfer over synchronizations and ...
متن کاملAliasing Restrictions of C11 Formalized in Coq
The C11 standard of the C programming language describes dynamic typing restrictions on memory operations to make more effective optimizations based on alias analysis possible. These restrictions are subtle due to the low-level nature of C, and have not been treated in a formal semantics before. We present an executable formal memory model for C that incorporates these restrictions, and at the ...
متن کاملOverhauling SC atomics in C11 and OpenCL
Despite the conceptual simplicity of sequential consistency (SC), the semantics of SC atomic operations and fences in the C11 and OpenCL memory models is subtle, leading to convoluted prose descriptions that translate to complex axiomatic formalisations. We conduct an overhaul of SC atomics in C11, reducing the associated axioms in both number and complexity. A consequence of our simplification...

متن کاملLowering C11 Atomics for ARM in LLVM
This report explores the way LLVM generates the memory barriers needed to support the C11/C++11 atomics for ARM. I measure the influence of memory barriers on performance, and I show that in some cases LLVM generates too many barriers. By leaving these barriers out, performance increases significantly. I introduce two LLVM passes, which will remove these extra barriers, improving performance in...
