* gcc11: warnings related to struct args allocation..Kaz Kylheku2021-09-081-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Paul A. Patience, GCC 11 warns about situations in a few places where we do args_decl(args, 0) to allocate an absolutely empty argument list object. (This by the way, is only done in places where we are absolutely sure that the function we call will not be accessing the arguments. The usual rule is that there have to be at least ARGS_MIN arguments allocated, currently 4, and code relies on that being the case! So the places which call args_decl(args, 0) are coded carefully, checking that args is not passed anywhere where ARGS_MIN space is required.) Anyway, in the 0 case, the val arg[1] member of struct args is not allocated at all, because we call alloca(offsetof (struct args, arg)). Now GCC 11 notices this and complains that accesses to the other members like args->fill or args->list are using a struct that has not been entirely allocated. This, even though those members lie entirely within the allocated area. The fix for this is two faceted. Firstly, on C99, this diagnostic goes away if we make one simple change: declare the arg array as a flexible array member: val arg[]. However, we still support C90 in maintainer mode. So in maintainer mode, we stick with the 1. But we ensure that the places which call args_decl(args, 0) will pass 1 instead of 0, so the whole structure is allocated. * lib.h (FLEX_ARRAY): New macro: empty definition in C99 or later, otherwise 1. * args.h (struct args): Declare the size of the arg member using the new FLEX_ARRAY macro from lib.h. (ARGS_ABS_MIN): New macro, the absolute args minimum: zero in C99 mode, 1 in maintainer C90 mode. * ffi.c (ffi_struct_in, ffi_struct_get, make_zstruct): Use ARGS_ABS_MIN instead of 0 when preparing dummy args for make_struct call. * struct.c (struct_from_plist, struct_from_args, make_struct_lit): Use ARGS_ABS_MIN instead of zero when preparing dummy args for make_struct_impl or make_struct call.

* c_num: now takes self argument.Kaz Kylheku2020-06-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The c_num and c_unum functions now take a self argument for identifying the calling function. This requires changes in a large number of places. In a few places, additional functions acquire a self argument. The ffi module has the most extensive example of this. Some functions mention their name in a larger string, or have scattered literals giving their name; with the introduction of the self local variable, these are replaced by references to self. In the following changelog, the notation TS stands for "take self argument", meaning that the functions acquires a new "val self" argument. The notation DS means "define self": the functions in question defines a self variable, which they pass down. The notation PS means that the functions pass down an existing self variable to functions that now require it. * args.h (args_count): TS. * arith.c (c_unum, c_num): TS.

* quasistrings: reduce consing.Kaz Kylheku2020-05-301-0/+12
| | | | | | | | | | | | | | | | | | | Quasistrings compile to code that requires on the sys:fmt-join function to glue strings together. Rewriting that function to avoid converting its arguments from struct args * to a list. * eval.c (fmt_join): Static function removed. * lib.c (cat_str_measure, cat_str_append): more_p parameter changed to int type, which better matches the C style Boolean values it takes. (fmt_join): New external function. * lib.h: Declared. * args.h (args_more_nozap, args_get_nozap): New inline functions allowing multiple iterations over arguments without making a copy.
* umethod: use new dynamic args to avoid consing list.Kaz Kylheku2020-03-231-0/+1
| | | | | | | | | | | | | * args.c (args_cat): New function. * args.h (args_cat): Declared. * struct.c (umethod_args_fun): env parameter is now a dynamic args object. Code adjusted accordingly. (umethod): Duplicate the args into a dynamic args object instead of consing up a list and also eliminate the temporary cons since we can pass the additional argument using the car field of the dynamic args.
* New type args with DARG type code.Kaz Kylheku2020-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | An object of args type captures into the heap the "struct args" argument list that normally appears only on the stack. Such an object also has space for a car and cdr field, which can come in handy. * args.c (dyn_args): New function: hoist a struct args * into an args heap object. * args.h (dyn_args): Declared. * gc.c (finalize, mark_obj): Handle DARGS type code. * hash.c (equal_hash): Handle DARG via eq equivalence. * lib.c (args_s): New symbol variable. (code2type): Map DARG to args symbol. (equal): Handle DARG type, using eq equivalence for now. (obj_init): Initialize args_s with interned symbol. * lib.h (enum type, type_t): New type code, DARG. (struct dyn_args): New struct. (union obj): New member, a of type struct dyn_args. * txr.1: Documented args type under typeof.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * args.c (args_normalize): Renamed to args_normalize_exact, because this tries to split the arguments between an exact array fill quantity and trailing list. Not all places using this function actually need an exact fill, which causes unnecessary consing when args->fill is reduced in order to move items to args->list. (args_normalize_least): New function. Variant of args_normalize that can be used by functions which only require a minimum fill. (args_normalize_fill): Use args_normalize_least rather than args_normalize_exact. This reduces consing in generic_funcall, in handling variadic calls where arrayed arguments have been supplied for trailing parameters. * args.h (args_normalize): Renamed to args_normalize_exact. (args_normalize_least): Declared. (args_get_list, args_get_rest): Use args_normalize_exact. (args_clear): Inline function removed. Was used only in one place in generic_funcall and is no longer. * eval.c (gather_free_refs): Use args_normalize_least. (prod_common): Use args_normalize_exact. * ffi.c (ffi_call_wrap): Use args_normalize_least. * lib.c (generic_funcall): Use args_normalize_least in switch statement that handles various callable non-function objects. When copying args, ensure that there are ARGS_MIN. A different strategy is used for producing the trailing args for variadic calls, further reducing consing. Rather than normalize the args to the fixed number, and then set args->fill to zero so that args contains just the list, we use args_cat_zap_from to create a copy of the args in which the fixed ones are trimmed out. The resulting args is not renormalized to be purely a list so no consing or list traversal takes place. If the rebalancing is needed, the called function will have to do it. (dwim_set): Streamline the code that handles hashes assigned via two or three args. * struct.c (method_args_fun, umethod_args_fun): Use args_normalize_exact.

Implementation basis for vec intrinsic function. (alist_removev, alist_nremovev): New functions. (multi_sort): Switch from mapcarv to mapcarl. (unique): Converted. (uniq): Allocate struct args for calling unique. (obj_init): list_f function now based on new listv, rather than identity. * list.h (varg): New typedef. (struct func): All variadic function pointers converted to use struct args.
