* c_num: now takes self argument.Kaz Kylheku2020-06-291-27/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove unnecessary #include directives.Kaz Kylheku2020-04-221-2/+0
| | | | | | | | | | Time for some spring cleaning. * args.c, arith.c, buf.c, cadr.c, chksum.c, debug.c, ftw.c, gc.c, gencadr.txr, glob.c, hash.c, lisplib.c, match.c, parser.c, parser.l, parser.y, rand.c, signal.c, stream.c, strudel.c, syslog.c, tree.c, unwind.c, utf8.c, vm.c: Numerous unnecessary #include directives removed.
* arith: move c_unum and unum declaration into lib.hKaz Kylheku2020-04-221-1/+0
| | | | | | | | | | | | | | | | The c_unum and unum functions are fairly often needed and and are closely related to c_num and num, which have always been declared in lib.h even though they live in arith.c. Files not doing arithmetic are including "arith.h" just for the sake of c_num or unum. * arith.h (c_unum, unum): Declarations removed. * lib.h (c_unum, unum): Declarations moved here. * chksum.c, debug.c, stream.c, strudel.c, sysif.c, vm.c: These files no longer require #include "arith.h" as a result, which is therefore removed.
* warning cleanup: remove unused parameters.Kaz Kylheku2020-04-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the second round of an effort to enable GCC's -Wextra option. All function parameters that are unused and are removable are removed. They are eliminated from the function defintions, declarations, callers, and any related function pointer variables or structure members. * arith.c (nary_simple_op): Remove unused self parameter. See lib.c: maxv, minv. * chksum.c (crc32_buf, crc32_str): Remove unused self parameter. (crc32): Don't pass self to the above functions. * eval.c (copy_env_handler, copy_bh_env_handler): Remove unused parent parameter. See unwind.c. (supplement_op_syms): Remove unused max parameter. (me_op): Don't pass max to supplement_op_syms. * lib.c (seq_iter_rewind): Remove unused self parameter. (lazy_flatten_func): Remove unused env parameter. (lazy_flatten): Use func_n1 to create non-environment-carrying funtion out of lazy_flatten_func. (maxv, minv): Don't pass self parameter to nary_simple_op. (middle_pivot): Remove unused lessfun param. (quicksort): Don't pass lessfun to middle_pivot. (diff, isec): Don't pass self to seq_iter_rewind. * lib.h (seq_iter_rewind, nary_simple_op): Declarations updated. * struct.c (get_super_slots): Remove unused self parameteer. (make_struct_type): Don't pass self to get_super_slots. * sysif.c (flock_unpack): Remove unused self parameter. (fcntl_wrap): Don't pass self to flock_unpack. * unwind.c (uw_push_cont_copy): Remove parent parameter from function pointer parameter. See eval.c: copy_env_handler. (call_copy_handlers): Remove parent parameter and don't pass that argument to the indirect call via pointer to the copy handler function. (revive_cont, capture_cont): Don't pass 0 value to removed parent parameter of call_copy_handlers. * unwind.h (struct uw_cont_copy): Function pointer member copy loses parent parameter. (uw_push_cont_copy): Declaration updated.

| | | | | | | | | | | | | | | | | | | | | * chksum.c (sha256_stream_impl): New static function, formed out of bulk of sha256_stream. Takes a pointer to a buffer where the digest is stored. (sha256_ensure_buf): New static function. (sha256_stream): Take buf argument; use sha256_ensure_buf to allocate a buffer if necessary, and to obtain the low-level buffer pointer. Implementation moved into sha256_stream_impl. (sha256_buf, sha256_str): Take pointer to digest buffer; don't allocate a buf object, don't return anything. (sha256): Take buf argument; use sha256_ensure_buf to allocate a buffer if necessary, and to obtain the low-level buffer pointer, which is passed to sha256_buf and sha256_str.
