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?
