Is std::atomic supported by Nios® II ? - Is std::atomic supported by Nios® II ? Description The std::atomic in C programming is Nios® II software development is not supported. The Nios® II GCC compiler is running by default with this feature "Thread Model: single", and cannot be modified. Resolution Nios® II does not have any atomic instructions. Hence, the "Thread Model: single" is the default setting for the compiler. To overcome this issue, Altera recommends using the Avalon Mutex Core, which gives Nios II the atomic operation.
