Given this in tree.h:
struct int_n_trees_t {
tree signed_type;
tree unsigned_type;
};extern struct int_n_trees_t int_n_trees[NUM_INT_N_ENTS]; And this in tree.c: struct int_n_trees_t int_n_trees [NUM_INT_N_ENTS]; What is the right way to mark these for garbage collection? I can't seem to get int_n_trees[] to show up in any of the gc-related generated files. I need the int_n_trees[] trees to be locked into memory, but I see signs that they're being reclaimed instead.
