* Use tnil instead of if2 in arithmetic predicates.Kaz Kylheku2018-12-131-9/+9
| | | | | * arith.c (zerop, plusp, minusp): style: if2(expr, t) should be using tnil(expr).
* plusp: wrong name in error message.Kaz Kylheku2018-12-131-1/+1
| | | | * arith.c (plusp): plusp wrongly reports itself as zerop.
* Streamline logand and logior slightly.Kaz Kylheku2018-11-251-18/+4
| | | | | | | | * arith.c (logand, logior): Remove wasteful zerop tests which involve a type check. Also don't check for a == b equivalence in CHR and NUM cases; this is a rare case that just adds to the cycles and instruction count. Blindly copying and pasting this code is what led to the bug in logxor.
* logxor: fix seriously broken function.Kaz Kylheku2018-11-251-0/+43
| | | | | | | | | | | | | Reported by Guillaume le Vaillant. * arith.c (logxor): Fix broken behavior when the arguments are the same nonzero fixnum, or the same bignum object. (logxor_old): New function: verbatim copy of previous logxor. * eval.c (eval_init): Register logxor intrinsic to the broken function if compatibility is 202 or less. * txr.1: Compat note added.
* compiler: use binary versions of common math functions.Kaz Kylheku2018-11-161-0/+11
| | | | | | | | | | | | | | | * arith.c (arith_init): Register functions in the sys package: b<, b>, b<=, b=, b+, b-, b*, b/ and neg. * share/txr/stdlib/compiler.tl (%nary-ops%, %bin-ops%, %bin-op%): New global variables. (compiler comp-fun-form): Transform two-argument calls to any of the variadic functions in %nary-ops% functions into calls to their binary counterpart. These calls are faster, since they bypass the wrapper which deals with the variable argument list. Also, we detect unary - and map it to the new sys:neg function, and reduce the one-argument cases of certain functions to noops.
* math: remove redundant type checks from NUM.Kaz Kylheku2018-11-161-118/+118
| | | | | | | | | | | | * arith.c (plus, minus, neg, abso, signum, mul, trunc, mod, floordiv, plusp, minusp, evenp, oddp, gt, lt, ge, le, numeq, expt, exptmod, isqrt, gcd, flo_int, logand, logior, logxor, comp_trunc, lognot, logtrunc, sign_extend, ash, bit, logcount, tofloat, toint, width, poly, rpoly): Use the unchecked c_n rather than c_num on quantities that are known to be of NUM and CHR type. * lib.h (c_n): New inline function.
* type_check: take function name arg.Kaz Kylheku2018-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * arith.c (flo_int): Pass down name to type_check. * eval.c (copy_env, env_fbind, env_vbind, env_vb_to_fb, func_get_name, lexical_var_p, lexical_fun_p, lexical_lisp1_binding, squash_menv_deleting_range, op_upenv): Pass relevant Lisp function name to type_check. (lookup_global_var, lookup_sym_lisp1, lookup_fun, lookup_mac, lookup_symac, lookup_symac_lisp1): For these widely used functions, pass situational prefix in place of function name. They may get a funtion name argument in the future. * gc.c (gc_finalize): Pass function name to type_check. * lib.c (throw_mismatch): Take function nme argument, incorporate into mesage. (lcons_fun, c_flo, string_extend, symbol_name, symbol_package, get_package, package_name, func_get_form, func_get_env, func_set_env, vec_set_length, length_vec, size_vec, list_vec, lay_str_force, lay_str_force_upto, lazy_str_get_trailing_list, from, too, set_from, set_to): Pass relevant Lisp function name to type_check. (symbol_setname, symbol_visible): Pass indication of internal error into type_check, since this doesn't pertain to any Lisp function being wrong. * lib.h (throw_mismatch): Declaration updated. (type_check): Take new parameter and pass down to throw_mismatch. * signal.c (set_sig_handler): Pass name down to type_check.
* math: improve error diagnosis.Kaz Kylheku2018-11-071-116/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | More streamlined code, better identification of functions. * arith.c (not_number, not_integer, invalid_ops, invalid_op, divzero): New static functions.

Use new static functions for reporting common errors. Pass function name to new argument of c_flo function. * buf.c (buf_put_float, buf_put_double): Pass function's Lisp name to c_flo function. * ffi.c (ffi_float_put, ffi_double_put): Likewise. * lib.c (c_flo): Takes new argument, name of calling function. * lib.h (c_flo): Declaration updated. * stream.c (formatv): Pass function name to c_flo.

Register flo-get-round-mode and flo-set-round-mode intrinsic functions. * configure: Test for fesetround and fegetround variables, and the associated constants, prpoducing a HAVE_ROUNDING_CTL_H variable in config.h. * txr.1: Documented new variables and functions.
* logcount: new function.Kaz Kylheku2018-05-181-0/+40
| | | | | | | | | | | | | | | | | | This is in ANSI CL; potentially useful and hard to implement efficiently in user code. * arith.c (logcount): New function. * eval.c (eval_init): Register logcount intrinsic. * lib.h (logcount): Declared. * mpi/mi.c (s_mp_count_ones): New static function.

* width: misleading error message.Kaz Kylheku2018-05-181-1/+1
| | | | | * arith.c (width): Fix incorrect name in type error diagnostic. There is no such function as integer-length.
* bugfix: include most negative two's in cnum range.Kaz Kylheku2018-04-291-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The INT_PTR_MIN value isn't the smallest value actually representable in cnum, because it is just the additive inverse of INT_PTR_MAX. In two's complement, the INT_PTR_MIN-1 value is still representable. But we are excluding it. If a Lisp integer has the value INT_PTR_MIN-1, the c_num function will fail to convert it to a cnum. This situation occurs in FFI, where code may expect that the Lisp value #x-80000000 can convert to an external 32 bit integer type. This will be done by way of a conversion to cnum first via c_num (see ffi_i32_put for instance, which calls c_i32 which relies on c_num). * arith.c (INT_PTR_MAX_SUCC_MP): New static variable. This holds a bignum equivalent to INT_PTR_MAX + 1. (in_int_ptr_range): We now check whether the value against the range [-(INT_PTR_MAX + 1), (INT_PTR_MAX + 1)] and then check all possible return values. The MP_LT case is clearly in range, and MP_GT is out of the range. The interesting situation is MP_EQ: in that case we just test the sign to see whether we are looking at -(INT_PTR_MAX + 1). (int_flo): INT_PTR_MIN is referenced in this function, so we use INT_PTR_MIN - 1 instead. This allows that value to be handled via the simple bignum(n) case. (arith_init): Initialize INT_PTR_MAX_SUCC_MP. We cannot initialize it to INT_PTR_MAX + 1 directly because that expression overflows: insted we use INT_PTR_MIN - 1 and then flip the resulting bignum's sign. (arith_free_all): Call mp_clear on the new variable to release its digit buffer. * ffi.c (make_ffi_type_enum): Use INT_PTR_MIN - 1 as the initial value of the highest variable, to accurately calculate the range of the enum values if they contain INT_PTR_MIN - 1.
* code review: switch case breaks.Kaz Kylheku2018-03-081-0/+3
| | | | | | | | | | * arith.c (c_unum): Add fallthrough comment. (minus): Add missing break after case that handles char minus heap object.. This luckily isn't a bug because type(anum) isn't RNG, and so when it falls through, the next case also falls through. * lib.c (car): Add missing fallthrough comment.
* New function: bignum-len.Kaz Kylheku2018-03-061-0/+13
| | | | | | | | | * arith.c (bignum_len): Wew function. (arith_init): Register bignum-len intrinsic. * arith.h (bignum_len): Declared. * txr.1: Documented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPI has a mp_size type for sizing of the digit arrays and some other uses. It is not consistently used. Moreover, it is typedef'd as a signed type. The type int is used for iterating over digits, instead of the matching mpi_size type. The int type is used as a size argument in some functions, and in functions that return the number of bits. This patch makes mp_size unsigned and replaces most uses of int with a more appropriate type. Because mp_size is now used for indexing, and is unsigned, some downward loop termination tests have to be changed; the always true condition ix >= 0 cannot be used. * arith.c (width): Use mp_size for local variable which iterates over digits inside mpi_int object, and for bit count. Use unum to convert bit count to Lisp integer: mp_size could be out of range of cnum. * mpi/mpi-types.h (mp_size): Typedef to unsigned. (MP_SIZE_MAX): New macro. (MP_DIGIT_BIT, MP_WORD_BIT): Cast the value to mp_size rather than to int. * mpi/mpi.c (s_mp_defprec): Declare variable as mp_size. (s_mp_setz, s_mp_copy, mp_size, s_highest_bit_mp, s_mp_set_bit, s_mp_ispow2, s_mp_outlen, mp_set_int, mp_set_uintptr, mp_set_double_intptr, mp_expt, mp_sqrt, mp_exptmod, mp_hash, mp_gcd, mp_shift, mp_bit, mp_to_double, mp_print, mp_read_signed_bin, mp_signed_bin_size, mp_read_unsigned_bin, mp_unsigned_bin_size, mp_to_unsigned_bin, mp_to_unsigned_buf, mp_count_bits, mp_is_pow_two, mp_read_radix, mp_radix_size, mp_value_radix_size, mp_toradix_case, s_mp_setz, s_mp_copy, mp_size, s_highest_bit_mp, s_mp_set_bit, s_mp_mul_2, s_mp_mod_2d, s_mp_div_2d, s_mp_div_d, s_mp_sqr, s_mp_sqr, s_mp_div, s_mp_cmp, s_mp_cmp_d, s_mp_ispow2, s_mp_outlen): In all these functions, use size_t for external size, mp_size for number of digits and bits, in return values, arguments and local variables. Tests in descending loops are adjusted for unsigned logic. * mpi/mpi.h (mp_get_prec, mp_set_prec, mp_read_signed_bin, mp_signed_bin_size, mp_read_unsigned_bin, mp_unsigned_bin_size, mp_to_unsigned_buf, mp_count_bits, mp_is_pow_two, mp_radix_size, mp_value_radix_size): Declarations updated. * mpi/mplogic.c (mpl_not, mpl_and, mpl_or, mpl_xor, mpl_rsh, mpl_lsh, mpl_num_set, mpl_num_clear, mpl_parity): Just like in mpi.c * rand.c (make_random_state): Use mp_size and ucnum for local variables holding digit and bit counts. * sysif.c (off_t_num): Use mp_size for digit count.
* ash: check range of bits argument.Kaz Kylheku2017-06-171-0/+5
| | | | | | | | | mp_shift takes an int argument, but we decode bits to a cnum, leaving possible room for overflow, such as when cnum is 64 bits and int is 32. If the value * arith.c (ash): Check that the value is in the range of INT_MIN to INT_MAX.
* ash: fix wrong function name in diagnostics.Kaz Kylheku2017-06-171-3/+3
| | | | | * arith.c (ash): Refer to ash in error messages rather than ashift.
* bugfix: sign-extend broken for bignums.Kaz Kylheku2017-06-141-0/+1
| | | | | | | | | | | | | * arith.c (sign_extend): After taking the two's complement which works at the granularity of digits, not the exact number of bits, we must truncate the number to the exact number of bits before negating. Otherwise we end up with an excessively large value. For instance if a bignum like #x80... is sign extended tightly to the upper 1 bit, the resulting value is something like #-xFFFF80..., rather than #x-80... as it should be. There are extra 1 bits padding up to the bignum digit. These must be chopped away.
* better error message for unum conversion.Kaz Kylheku2017-06-061-1/+1
| | | | | | * arith.c (c_unum): When the input value is negative, complain about that, not about uint_ptr_t, which means nothing in TXR Lisp.
* bits: external linkage.Kaz Kylheku2017-05-241-2/+1
| | | | | | | * arith.c (bits): Change the linkage from internal to external. * arith.h (bits): Declared.

* Rename c_uint_ptr_num; introduce cunum typedef.Kaz Kylheku2017-04-211-1/+1
| | | | | | | | | | | | | | | Unsigned version of cnum becomes less verbose. * arith.c (c_uint_ptr_num): Renamed to c_unum. * arith.h (c_uint_ptr_num): Declaration removed. (c_unum): Declared. * itypes.c (c_u32, c_u64, c_uint): Follow rename. * lib.h (ucnum): New typedef. * rand.c (make_random_state): Follow rename.
* Bugfix: ash: right shifts of fixnums broken.Kaz Kylheku2017-04-201-1/+2
| | | | | | | | * arith.c (ash): The bn <= num_bits comparison here is always true because bn < 0, leading to undefined behavior when bn is sufficiently negative, due to the shift being as wide or wider than the number of bits in a cnum.
* Use TAG_SHFIT instead of hard-coded 2.Kaz Kylheku2017-04-201-3/+3
| | | | | | | * arith.c (comp_trunc, logtrunc, ash): The constant 2 appears here, which corresponds to TAG_SHIFT: the number of tag bits in an int_ptr_t word. It must be replaced by TAG_SHIFT.
* Rename badly named default_bool_argKaz Kylheku2017-03-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.h (default_bool_arg): Inline function renamed to default_null_arg. * eval.c (if_fun, pad, ginterate, giterate, range_star, range, constantp, macroexpand_1, macro_form_p, expand_with_free_refs, do_expand, eval_intrinsic, func_get_name, make_env_intrinsic): Follow rename. * arith.c (lognot): Likewise. * gc.c (gc_finalize): Likewise. * glob.c (glob_wrap): Likewise. * hash.c (group_reduce, gethash_n): Likewise. * lib.c (print, multi_sort, lazy_str, vector, iff, tok_str, split_str_keep, search_str, remove_if, val): Likewise. * match.c (match_fun): Likewise. * parser.c (lisp_parse_impl, regex_parse): Likewise. * rand.c (make_random_state): Likewise. * regex.c (read_until_match, search_regex, regex_compile): Likewise. * socket.c (sock_accept, sock_connect): Likewise. * stream.c (open_files_star, open_files, run, open_process, open_tail, get_string, record_adapter): Likewise. * struct.c (static_slot_ensure, static_slot_ens_rec, clear_struct, make_struct_type): Likewise. * sysif.c (exec_wrap, errno_wrap, cobj_ops_init): Likewise. * unwind.c (uw_capture_cont, uw_find_frames_impl): Likewise.

| | | | | | | | | | | | | | * arith.c (trunc1): New static function. (trunc): Detect a missing second argument and call func1. * eval.c (eval_init): Update registration of trunc intrinsic to make second arg optional. * txr.1: Describe optional argument of trunc. Trunc documentation is merged with the floor, ceil and round section. The mod and trunc-rem functions are split off into their own sections, leaving the / function described by itself. The documentation of / is substantially revised.

* Add useful sys:bits function.Kaz Kylheku2017-02-041-0/+8
| | | | | | | | | | | | | | | | | | sys:bits converts a Lisp value to an integer whose value is the object's bit pattern interpreted as a pure binary number. (Only the "unboxed" part of the object that is stored in variables or passed into functions, not any "boxded" heap part which is referenced.) this holds: (eq a b) <--> (= (sys:bits a) (sys:bits b)) Two values a and b are the same object iff their sys:bits values are the same integer. * arith.c (bits): New static function.

| | | | | | | | | | * arith.c (tofloatz, tointz): New functions. * arith.h (tofloatz, tointz): Declared. * eval.c (eval_init): Register tofloatz and tointz intrinsics. * txr.1: Documented new functions.
* Do not leave COBJ-ified mp_int uninitialized.Kaz Kylheku2016-06-081-0/+1
| | | | | | | | | | | | | | | Here we ensure that the digits pointer of an uninitialized mp_int is nulled out. The garbage collector could conceivably encounter such an object, in which case mp_clear will then try to free a garbage pointer. This could happen if an exception is thrown out of numeric code due to low memory, interrupting its execution, leaving behind an unfilled object produced by make_ubignum. * arith.c (make_ubignum): Perform minimal initialization of the mp_int using new function. * mpi/mpi.h (mp_init_minimal): New inline function.
* Fix leaks in use of MPI and within MPI.Kaz Kylheku2016-06-081-6/+6
| | | | | | | | | | | | | | | | * arith.c (logand, logior, logxor): Use make_ubignum to create an uninitialized bignum, because mp_and, mp_or, and mp_xor expect argument c to be uninitialized, and clobber it by initializing. (comp_trunc): Use make_ubignum for b argument, because mp_trunk_comp initializes it. (lognot, logtrunc): Use make_ubignum for b, because mp_trunc initializes it. * mpi/mpi.c (mp_and, mp_or, mp_xor, mp_comp, mp_trunc_comp, mp_trunc, mp_shift, mp_bit): Do not initialize the tmp that is passed as argument b to mp_2comp, since that function initializes it.
* New --free-all option for freeing memory on exit.Kaz Kylheku2016-06-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although we are garbage-collected, being able to clean up on shutdown is nevertheless useful for uncovering leaks. Leaks can occur, for instance, due to neglect to free out-of-heap satellite data from objects that are reclaimed by gc. This feature is long overdue. * arith.c, arith.h (arith_free_all): New function. * gc.c, gc.h (gc_free_all): New function. * lib.c (init): Remove program name parameter and redundant initialization of progname globl variable. * lib.h (progname): Superfluous declaration removed. This is already declared in txr.h. (init): Declaration updated. * regex.c (char_set_destroy): Do not check the static allocation flag here; just destroy the object. Do check for a null pointer, though. (char_set_cobj_destroy): This cobj destructor now checks the static flag of the char set object and avoids freeing it. Thus our char set singletons are left alone by gc, but our global freeing function takes care of them. (wide_cs): New static variable moved out of wide_display_char_p to static scope. (regex_free_all): New function. * regex.h (regex_free_all): Declared. * txr.c (progname): const qualifier and initializer removed. (main): Ensure progname is always dynamically allocated, even in the argv[0] == 0 case. Do not pass progname to init; it doesn't take that argument any more. (free_all): New static function. (txr_main): Implement --free-all option. * txr.h (progname): Declaration updated.
* Adding fixnum-min and fixnum-max variables.Kaz Kylheku2016-04-271-0/+2
| | | | | | | * arith.c (arith_init): Registered fixnum-min and fixnum-max variables. * txr.1: Documented.
