* Large scale conversion to new way of handling arguments.Kaz Kylheku2015-08-231-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Function arguments are now allocated on the stack using alloca, in conjunction with the struct alloc header structure. The generic_funcall and apply functions are refactored for this, as are most functions that take variadic arguments. * args.c (args_add_list, args_cons_list): Functions removed. (args_normalize, args_normalize_fill): New functions. (args_get_checked): Draw arguments from list when array runs out. (args_copy, args_copy_zap): New functions. * args.h (ARGS_MAX): Reduced to 32. (ARGS_MIN): New preprocessor symbol. (args_init): Call args_init_list. (args_add2, args_add3, args_add4): New inline functions. (args_more): Take into account list, which may hold additional arguments. (args_two_more): New inline function. (args_normalize, args_normalize_fill): Declared. (args_get_list): Normalize all arguments into one list and return it. (args_get_rest, args_at, args_atz): New inline functions. (args_get): Draw arguments from list when array runs out. (args_clear): New inline function. * arith.c (maskv): Convert to new args. * eval.c (APPLY_ARGS): Preprocessor symbol removed. (bind_args): Converted to accept struct args. (apply): Function reduced down to trivial adapter which converts a list of arguments to args, and calls the new generic_funcall. (applyv): New static function: struct args wrapper around apply_intrinsic. (iapply): Converted to struct args. (call): Static function removed. The call intrinsic function binding now goes directly to generic_funcall. (list_star_intrinsic, interp_fun): Converted to struct args. (op_catch): Adjustments for bind_args, which requires a struct args arglist. (me_op): Must use the new minl and maxl, since minv and maxv don't take lists any more.

(eval_init): call_f initialized from generic_funcall rather than call. apply registered to applyv rather than apply_intrinsic. Registrations for zip, hash_from_pairs, vec, alist-remove, alist-nremove, and throw similarly updated to new or renamed functions. * eval.h (interp_fun, mapcarv): Declarations updated. (mapcarl): Declard. * hash.c (hashv): Converted to struct args. (hashl): New function. (hash_construct): Use hashl, not hashv.

(func_n0v, func_n1v, func_n2v, func_n3v, func_n4v): Converted. (func_n1ov, func_n2ov, func_n3ov): Converted. (generic_funcall): Converted to take struct args. (funcall, funcall1, funcall2, funcall4): Pass stack-allocated struct args as trailing arguments to variadic functions, and to generic_funcall.

(transpose): Now a wrapper for transposev. (do_chain, chainv, do_chand, chandv, do_juxt, juxtv, do_and, andv, do_or, orv, do_not, do_iff): Converted. (vectorv): New function. 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. (appendv, nconcv, lazy_appendv, multi, nary_op, plusv, minusv, mulv, gtv, ltv, gev, lev, numeqv, numneqv, maxv, minv, exptv, gcdv, lcmv, logadnv, logiorv, maskv, lessv, greaterv, lequalv, gequalv, func_f0v, func_f1v, func_f2v, func_f3v, func_f4v, func_n0v, func_n1v, func_n2v, func_n3v, func_n4v, func_n0v, func_n1v, func_n2v, func_n3v, func_n4v, func_n1ov, func_n2ov, func_n3ov, generic_funcall, chainv, chandv, juxtv, adnv, orv, unique): Declarations updated. (lazy_appendl, listv, maxl, minl, transposev, vectorv, alist_removev, alist_nremovev): Declared. * stream.c (make_catenated_stream_v): New function. (aformat): Renamed to formatv.

New syslog variables and functions registered. * lib.c (logandv, logiorv): New functions. * lib.h (logandv, logiorv): Declared. * txr.c (main): Call syslog_init. * syslog.c: New file. * syslog.h: New file. * txr.1: Updated. * txr.vim: Regenerated.
* * arith.c (bignum_from_long): New function.Kaz Kylheku2012-10-011-0/+11
| | | | | | | | | * arith.h (bignum_from_long): Declared. * lib.c (int_str): Streamlined. Only use mp_read_radix in the case when wcstol fails, because now we have bignum_from_long to handle all values of long. Ensure that the bignum is normalized, in case it falls in the fixnum range (does not happen on our usual platforms).

If second argument is present (not nil) then call comp_clamp. * eval.c (eval_init): Change registration of logcomp to allow optional argument. * lib.h (logcomp): Declaration updated. * mpi-patches/add-bitops: New mp_clamp_comp function implemented.
* Adding complementing function.Kaz Kylheku2012-09-161-0/+20
| | | | | | | | | | * arith.c (logcomp): New function. * eval.c (eval_init): logcomp registered as intrinsic. * lib.h (logcomp) declared. * mpi-patches/add-bitops: Fixed bugs in mp_xor. Implemented mp_comp.

* * arith.c (INT_PTR_MAX_MP): New static variable.Kaz Kylheku2012-04-101-1/+8
| | | | | | | | | | | | | | | (in_int_ptr_range): New function. (arith_init): Initialize INT_PTR_MAX_MP. * arith.h (in_int_ptr_range): Declared. * lib.c (c_num): Allow bignums to be converted to a cnum, if they are in range, rather than allowing only fixnums. * rand.c (make_random_state): Now that we have such a function, initialize random seed using time value from time_sec_usec rather than from time and clock. clock is bad for random seeding because it measures virtual time since the start of the process.
* NetBSD port.Kaz Kylheku2012-04-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | * arith.c (bignum_dbl_ipt): Added missing #if HAVE_DOUBLE_INTPTR_T around function * configure: NetBSD's shell is too pathetic to expand "$@" properly when there are no positional arguments, so I applied the ${@+"$@"} trick. (make): New variable. GNU make might be known only as gmake, so we now detect the command for our own use within the configure script and also for giving the user advice on what command to use for building. Put in a fix so that the attempt to run $make --version does not bail the script under "set -e" if that command terminates unsuccessfully. The check for clashing names has been moved earlier, so that the renaming #define's appear early in config.h (so config.h itself can rely on the renames). The identifier longlong_t has been added to the potential clash list. NetBSD exposes this identifier in spite of -D_POSIX_SOURCE=2, and it clashes with our longlong_t. The tests for integers wider than long long has been modified to actually compile a multiplication of two long-long-s into the wider precision. On the NetBSD system, with gcc 4.1.3, I found that the __int128 type is there, but doesn't actually work; compilation of arith.c bails with an internal compiler error. We now get this internal error at configure time and avoid using the type.

(time_sec, time_sec_usec): New functions. * lib.h (mut): Slight change to macro to eliminate compiler warning. (time_sec, time_sec_usec): Declared. * txr.1: Stub section for time and time-usec. * txr.vim: Highlighting for time and time-usec.
