Hi, I'm trying to compile code with the __builtin_uadd_overflow function. I'm using g++ 4.9.2. However, the compiler tells me it is not declared.
Thinking it could be some restriction to g++, I made a tiny C program with the function. Then gcc compiled it, but did not link (undefined reference to `__builtin_uadd_overflow').
How can I use this function? Can I use it on a C++ program?
