(alist_nremove1): Use equal rather than eq. (merge): Bugfix: unnecessary consing caused by using append instead of nconc on list pieces that are already destructively chopped up. This has implications for the efficiency of sort over lists! (multi_sort_less): Implement key functions.

(eval_init): hash-keys, hash-values, hash-pairs and hash-alist intrinsics introduced. * filter.c (trie_compress): Follow interface change of hash_next. * hash.c (hash_next): Silly interface which takes a pointer to the iterator has changed to just take the iterator.

* Code cleanup and tweaking.Kaz Kylheku2012-04-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | * gc.c (BACKPTR_VEC_SIZE): Preprocessor symbol renamed to CHECKOBJ_VEC_SIZE. (FULL_GC_INTERVAL): Increased to 40 since the modified algorithm now leaves less work for the full gc to do. (backptr, backptr_idx): Static variables renamed to checkobj and checkobj_idx. (mark): Follows rename of backptr and backptr_idx. (gc): Commented out handy printf added. (gc_set): Use in_malloc_range check to avoid adding to the check array pointers which are being stored in non-heap locations, since non-heap locations are already GC roots. (gc_mutated): Follows variable renaming. (gc_push): Just do the push using gc_set. * lib.c (malloc_low_bound, malloc_high_bound): New variables. (chk_malloc, chk_calloc, chk_realloc): Updated malloc_low_bound and malloc_high_bound. (in_malloc_range): New function. * lib.h (in_malloc_range): Declared.

(backptr_oflow, freshq, freshq_head, freshq_tail): New static variables. (make_obj): Place newly allocated generation 0 object into freshq. If freshq becomes full, transfer oldest item into generation 1. (mark_obj): If doing only a partial gc, then do not mark objects which are not generation 0. (mark_mem_region): Valgrind support: cannot mark t.type field undefined because it is a bitfield. Just mark the first SIZEOF_PTR bytes of the object defined. (mark): Under partial gc, mark the table of back pointers. (sweep_one): New static function from the prior guts of sweep. Reachable objects now get promoted to generation 1. (sweep): Under partial gc, sweep just the freshq which identifies the generation 0 objects, rather than the entire linked list of all the heaps. (gc): Trigger full gc also if the backptr list has overflowed due to gc having been disabled. Under generational gc, reset the static variables afterward: clear the list of backpointers, and the freshq. (gc_is_reachable): Under partial gc, report any mature object as reachable. (gc_set, gc_mutated): Handle backptr array overflow situation when gc is disabled. (gc_push): Bugfix: it is the newly pushed cons cell that has to be marked as a root, not the value being pushed. * hash.c (sethash): Use set macro for storing value. * lib.h (set, mut, mpush): Fix wrong-way #if test for these macros. The trivial versions were being defined uner CONFIG_GEN_GC and vice versa!

(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.
* * lib.c (vec_set_length): Use set instead of assignment.Kaz Kylheku2012-04-021-0/+1

| | | | | | | | | | | | | | | | | | | | | | | | | to places where we potentially assign a reference to a younger object inside a field located in an older object (chronological backreference) and also where we take the address of an object field, making it possible that the user of the address will do so. This patch does not take care of vectors. No, this is not an April Fool's joke. * eval.c (env_fbind, env_vbind, env_replace_vbind, lookup_var, lookup_sym_lisp1): Use set macro instead of assignment. * hash.c (hash_grow, set_hash_userdata, hash_next): Use set macro instead of assignment. * lib.c (rplaca, rplacd, string_extend, length_str, replace_str, rehome_sym, lazy_stream_func, lazy_str, lazy_str_force, lazy_str_force_upto, obj_init): Use set macro instead of assignment.
