Martin Jambor, Jan Hubicka: Optimizing C++ std::vector use in GCC 14

The talk will describe how the upcoming GCC 14 utilizes advanced interprocedural analysis in order to optimize code that heavily pushes elements into and pops them from C++ std::vector. One such example is JPEG XL library (libjxl) which GCC 14 can speed up by 40% without resorting to overaggressive inlining.
