Thanks, will do. One more question: does our code arrange for libgccjit to free heap-allocated buffers that Emacs allocates, or vice versa (libgccjit allocates memory that Emacs then frees)? And do we arrange for any callbacks from libgccjit, i.e. does libgccjit call functions implemented in Emacs? If the answer to any of these questions is YES, could you please point me to the relevant places in the code?
