* Help GCC compute modiff_incrPaul Eggert2023-05-141-11/+1
| | | | | | | | | | | * src/floatfns.c: Don’t include count-leading-zeros.h, since we no longer use it directly. (ecount_leading_zeros): Remove. (Flogb): Use elogb instead of doing it by hand. * src/lisp.h: Include count-leading-zeros.h. (elogb): New macro. (modiff_incr): Use it so that on typical platforms we use a hardware instruction instead of a loop.

* Be more careful about pointers to bignum valsPaul Eggert2019-08-211-3/+3
| | | | | | | | | | | | | | | This uses ‘const’ to be better at catching bugs that mistakenly attempt to modify a bignum value. Lisp bignums are supposed to be immutable. * src/alloc.c (make_pure_bignum): * src/fns.c (sxhash_bignum): Accept Lisp_Object instead of struct Lisp_Bignum *, as that’s simpler now. Caller changed. * src/bignum.h (bignum_val, xbignum_val): New inline functions. Prefer them to &i->value and XBIGNUM (i)->value, since they apply ‘const’ to the result. * src/timefns.c (lisp_to_timespec): Use mpz_t const * to point to a bignum value.
* Fix logb on zero, infinite, NaN argsPaul Eggert2019-01-061-16/+11
| | | | | | | | | Change logb to return -infinity, +infinity, and NaN respectively. Formerly logb returned an extreme fixnum to represent infinity, but this is no longer the right thing to do now that we have bignums and there is no extreme integer. * doc/lispref/numbers.texi (Float Basics), etc/NEWS: Document. * src/floatfns.c (Flogb): Implement this.

* | Speed up (+ 2 2) by a factor of 10Paul Eggert2018-09-031-31/+13

Also, simplify bignum memory management, fixing some unlikely leaks. This patch improved the performance of (+ 2 2) by a factor of ten on a simple microbenchmark computing (+ x 2), byte-compiled, with x a local variable initialized to 2 via means the byte compiler could not predict: performance improved from 135 to 13 ns. The platform was Fedora 28 x86-64, AMD Phenom II X4 910e. Performance also improved 0.6% on ‘make compile-always’. * src/bignum.c (init_bignum_once): New function. * src/emacs.c (main): Use it. * src/bignum.c (mpz): New global var. (make_integer_mpz): Rename from make_integer.

All uses removed. (floating_point_op): New function. (floatop_arith_driver): New function, with much of the guts of the old float_arith_driver. (float_arith_driver): Use it. (floatop_arith_driver, arith_driver): Simplify by assuming NARGS is at least 2. All callers changed. (float_arith_driver): New arg, containing the partly converted value of the next arg. Reorder args for consistency. All uses changed. (bignum_arith_driver): New function. (arith_driver): Use it. Do fixnum-only integer calculations in intmax_t instead of mpz_t, when they fit. Break out mpz_t calculations into bignum_arith_driver. (Fquo): Use floatop_arith_driver instead of float_arith_driver, since the op is known to be valid. (Flogcount, Fash): Simplify by coalescing bignum and fixnum code. (Fadd1, Fsub1): Simplify by using make_int.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c, src/bignum.h: New files. Only modules that need to know how bignums are implemented should include bignum.h. Currently these are alloc.c, bignum.c (of course), data.c, emacs.c, emacs-module.c, floatfns.c, fns.c, print.c. * src/Makefile.in (base_obj): Add bignum.o. * src/alloc.c (make_bignum_str): Move to bignum.c. (make_number): Remove; replaced by bignum.c’s make_integer. All callers changed. * src/conf_post.h (ARG_NONNULL): New macro. * src/json.c (json_to_lisp): Use it. * src/data.c (Fnatnump): Move NATNUMP’s implementation here from lisp.h. * src/data.c (Fnumber_to_string): * src/editfns.c (styled_format): Move conversion of string to bignum to bignum_to_string, and call it here. * src/emacs-module.c (module_make_integer): * src/floatfns.c (Fabs): Simplify by using make_int. * src/emacs.c: Include bignum.h, to expand its inline fns. * src/floatfns.c (Ffloat): Simplify by using XFLOATINT. (rounding_driver): Simplify by using double_to_bignum. (rounddiv_q): Clarify use of temporaries. * src/lisp.h: Move decls that need to know bignum internals to bignum.h. Do not include gmp.h or mini-gmp.h; that is now bignum.h’s job. (GMP_NUM_BITS, struct Lisp_Bignum, XBIGNUM, mpz_set_intmax): Move to bignum.h. (make_int): New function. (NATNUMP): Remove; all callers changed to use Fnatnump. (XFLOATINT): If arg is a bignum, use bignum_to_double, so that bignum internals are not exposed here. * src/print.c (print_vectorlike): Use SAFE_ALLOCA to avoid the need for a record_unwind_protect_ptr.
* | Fix bugs when rounding to bignumsPaul Eggert2018-08-221-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, since Emacs historically reported a range error when rounding operations overflowed, do that consistently for all bignum overflows. * doc/lispref/errors.texi (Standard Errors): * doc/lispref/numbers.texi (Integer Basics): Document range errors. * src/alloc.c (range_error): Rename from integer_overflow. All uses changed. * src/floatfns.c (rounding_driver): When the result of a floating point rounding operation does not fit into a fixnum, put it into a bignum instead of always signaling an range error. * test/src/floatfns-tests.el (divide-extreme-sign): These tests now return the mathematically-correct answer instead of signaling an error. (bignum-round): Check that integers round to themselves.
* | Add bignum support to floor, ceiling, etc.Paul Eggert2018-08-211-40/+55
| | | | | | | | | | | | | | | | | | | | | | Problem reported by Andy Moreton (Bug#32463#35 (d)). * src/floatfns.c (rounding_driver): Change the signature of the integer rounder to use mpz_t rather than EMACS_INT. All uses changed. Support bignums. (ceiling2, floor2, truncate2, round2): Remove. All uses changed to rounddiv_q or to a GMP library function. (rounddiv_q): New function. * test/src/floatfns-tests.el (bignum-round): New test.
* | Avoid libgmp aborts by imposing limitsPaul Eggert2018-08-211-23/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libgmp calls ‘abort’ when given numbers too big for its internal data structures. The numeric limit is large and platform-dependent; with 64-bit GMP 6.1.2 it is around 2**2**37. Work around the problem by refusing to call libgmp functions with arguments that would cause an abort. With luck libgmp will have a better way to do this in the future. Also, introduce a variable integer-width that lets the user control how large bignums can be. This currently defaults to 2**16, i.e., it allows bignums up to 2**2**16. This should be enough for ordinary computation, and should help Emacs to avoid thrashing or hanging. Problem noted by Pip Cet (Bug#32463#71). * doc/lispref/numbers.texi, etc/NEWS: Document recent bignum changes, including this one. Improve documentation for bitwise operations, in the light of bignums. * src/alloc.c (make_number): Enforce integer-width. (integer_overflow): New function. (xrealloc_for_gmp, xfree_for_gmp): Move here from emacs.c, as it's memory allocation. (init_alloc): Initialize GMP here, rather than in emacs.c. (integer_width): New var. * src/data.c (GMP_NLIMBS_MAX, NLIMBS_LIMIT): New constants. (emacs_mpz_size, emacs_mpz_mul) (emacs_mpz_mul_2exp, emacs_mpz_pow_ui): New functions. (arith_driver, Fash, expt_integer): Use them. (expt_integer): New function, containing integer code that was out of place in floatfns.c. (check_bignum_size, xmalloc_for_gmp): Remove. * src/emacs.c (main): Do not initialize GMP here. * src/floatfns.c (Fexpt): Use expt_integer, which now contains integer code moved from here. * src/lisp.h (GMP_NUMB_BITS): Define if gmp.h doesn’t.
* | Fix expt signedness bug --without-wide-intPaul Eggert2018-08-191-1/+1
| | | | | | | | | | | | | | | | Problem reported by Federico in: https://lists.gnu.org/r/emacs-devel/2018-08/msg00619.html * src/floatfns.c (Fexpt): Use TYPE_RANGED_FIXNUMP, not RANGED_FIXNUMP, to fix bug with unsigned comparison on platforms built --without-wide-int.

| | | | | | | | | | | | | | | | | | | | Problem and initial solution reported by Andy Moreton in: https://lists.gnu.org/r/emacs-devel/2018-08/msg00503.html * doc/lispref/numbers.texi (Math Functions): expt integer overflow no longer causes truncation; it now signals an error since bignum overflow is a big deal. * src/floatfns.c (Fexpt): Support bignum arguments. * test/src/floatfns-tests.el (bignum-expt): New test.
* | Fix bug with ‘mod’ and float+bignumPaul Eggert2018-08-181-4/+2
| | | | | | | | | | | | | | Problem reported by Andy Moreton in: https://lists.gnu.org/r/emacs-devel/2018-08/msg00442.html * src/floatfns.c (fmod_float): Work even if an arg is a bignum. * test/src/floatfns-tests.el (bignum-mod): New test.
* | Improve ‘abs’ performancePaul Eggert2018-08-171-17/+30
| | | | | | | | | | | | * src/floatfns.c (Fabs): Improve performance by not copying the argument if it would eql the result. As a minor detail, don't assume fixnums are two’s complement.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
