However, this is changing; -there are now new instructions which are well-defined in the presence of threads -and asynchronous signals, and the model for existing instructions has been -clarified in the IR. +LLVM supports instructions which are well-defined in the presence of threads and +asynchronous signals. The atomic instructions are designed specifically to provide readable IR and optimized code generation for the following: -* The new C++11 ``<atomic>`` header.
