TODO here. + + * filter.c (trie_add, trie_compress): Handle mutating assignments + via set macro. + + * gc.c (BACKPTR_VEC_SIZE, FULL_GC_INTERVAL): New preprocessor symbols. + (backptr, backptr_idx, partial_gc_count, full): New static variables. + (make_obj): Initialize generation to zero. + (gc): Added logic for deciding between full and partial gc. + (gc_set, gc_mutated): New functions. + + * gc.h (gc_set, gc_mutated): Declared. + + * hash.c (hash_mark): Changed useless use of vecref_l to vecref. + (gethash_f): Use set when assigning through *found since it + is a possible mutation. + + * lib.c (car_l, cdr_l, vecref_l): Got rid of loc macro uses. Using the + value properly is going to be the caller's responsibility. + (push): push may be a mutation, so use set. + (intern): Uset set to mutate a hash entry. + (acons_new_l, aconsq_new_l): Use set when replacing *list. + + * lib.h (PTR_BIT): New preprocessor symbol. + (obj_common): New macro for defining common object fields. + type_t is split into two bitfields, half a pointer wide, + allowing for generation to be represented. + (struct any, struct cons, struct string, struct sym, struct package, + struct func, struct vec, struct lazy_cons, struct cobj, struct env, + struct bignum, struct flonum): Use obj_common macro to defined + common fields. + (loc): Macro removed. + (set, mut): Macros conditionally defined for real functionality. + (list_collect, list_collect_nconc, list_collect_append): Replace + mutating operations with set. + + * match.c (dest_set, v_cat, v_output, v_filter): Replace + mutating operations with set. + + * stream.c (string_in_get_line, string_in_get_char, + strlist_out_put_string, strlist_out_put_char): Replace mutating + operations with set. + + * unwind.c (uw_register_subtype): Replace mutating operation with set. + +2012-04-02 Kaz Kylheku <kaz@kylheku.com> + * lib.c (vec_set_length): Use set instead of assignment.
