* | | Improve format-seconds accuracyPaul Eggert2018-08-251-4/+0
| | | | | | | | | | | | | | | | | | * doc/lispref/os.texi (Time Parsing): It works with bignums. * lisp/calendar/time-date.el (format-seconds): Take the floor so that the resulting arithmetic is exact.
* | | Fix bugs when rounding to bignumsPaul Eggert2018-08-222-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Move bignump, fixnump from C to LispPaul Eggert2018-08-211-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/objects.texi (Integer Type): Mention most-negative-fixnum and most-positive-fixnum as alternatives to fixnump and bignump. * lisp/subr.el (fixnump, bignump): Now written in Lisp. * src/data.c (Ffixnump, Fbignump): No longer written in C, as these new functions are not crucial for performance.
* | | Audit use of lsh and fix glitchesPaul Eggert2018-08-214-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I audited use of lsh in the Lisp source code, and fixed the glitches that I found. While I was at it, I replaced uses of lsh with ash when either will do. Replacement is OK when either argument is known to be nonnegative, or when only the low-order bits of the result matter, and is a (minor) win since ash is a bit more solid than lsh nowadays, and is a bit faster. * lisp/calc/calc-ext.el (math-check-fixnum): Prefer most-positive-fixnum to (lsh -1 -1). * lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width, prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1 32)) (Bug#32485#11). * lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode): Tighten sanity-check for bytecode overflow, by checking that the result of (ash pc -8) is nonnegative. Formerly this check was not needed since lsh was used and the number overflowed differently. * lisp/net/dns.el (dns-write): Fix some obvious sign typos in shift counts. Evidently this part of the code has never been exercised. * lisp/progmodes/hideif.el (hif-shiftleft, hif-shiftright): * lisp/term/common-win.el (x-setup-function-keys): Simplify. * admin/unidata/unidata-gen.el, admin/unidata/uvs.el: * doc/lispref/keymaps.texi, doc/lispref/syntax.texi: * doc/misc/calc.texi, doc/misc/cl.texi, etc/NEWS.19: * lisp/arc-mode.el, lisp/calc/calc-bin.el, lisp/calc/calc-comb.el: * lisp/calc/calc-ext.el, lisp/calc/calc-math.el: * lisp/cedet/semantic/wisent/comp.el, lisp/composite.el: * lisp/disp-table.el, lisp/dos-fns.el, lisp/edmacro.el: * lisp/emacs-lisp/bindat.el, lisp/emacs-lisp/byte-opt.el: * lisp/emacs-lisp/bytecomp.el, lisp/emacs-lisp/cl-extra.el: * lisp/erc/erc-dcc.el, lisp/facemenu.el, lisp/gnus/message.el: * lisp/gnus/nndoc.el, lisp/gnus/nnmaildir.el, lisp/image.el: * lisp/international/ccl.el, lisp/international/fontset.el: * lisp/international/mule-cmds.el, lisp/international/mule.el: * lisp/json.el, lisp/mail/binhex.el, lisp/mail/rmail.el: * lisp/mail/uudecode.el, lisp/md4.el, lisp/net/dns.el: * lisp/net/ntlm.el, lisp/net/sasl.el, lisp/net/socks.el: * lisp/net/tramp.el, lisp/obsolete/levents.el: * lisp/obsolete/pgg-parse.el, lisp/org/org.el: * lisp/org/ox-publish.el, lisp/progmodes/cc-defs.el: * lisp/progmodes/ebnf2ps.el, lisp/progmodes/hideif.el: * lisp/ps-bdf.el, lisp/ps-print.el, lisp/simple.el: * lisp/tar-mode.el, lisp/term/common-win.el: * lisp/term/tty-colors.el, lisp/term/xterm.el, lisp/vc/vc-git.el: * lisp/vc/vc-hg.el, lisp/x-dnd.el, test/src/data-tests.el: Prefer ash to lsh when either will do.
* | | Restore compatibility with Texinfo < 6Glenn Morris2018-08-211-4/+16

* | | Avoid libgmp aborts by imposing limitsPaul Eggert2018-08-211-166/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Add bignum support to exptPaul Eggert2018-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Document that ‘random’ is limited to fixnumsPaul Eggert2018-08-181-4/+3
| | | | | | | | | | | | | | | | | | Problem reported by Pip Cet (Bug#32463#20). * doc/lispref/numbers.texi (Random Numbers): * src/fns.c (Frandom): Adjust doc.
* | | Restore traditional lsh behavior on fixnumsPaul Eggert2018-08-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/numbers.texi (Bitwise Operations): Document that the traditional (lsh A B) behavior is for fixnums, and that it is an error if A and B are both negative and A is a bignum. See Bug#32463. * lisp/subr.el (lsh): New function, moved here from src/data.c. * src/data.c (ash_lsh_impl): Remove, moving body into Fash since it’s the only caller now. (Fash): Check for out-of-range counts. If COUNT is zero, return first argument instead of going through libgmp. Omit lsh code since lsh is now done in Lisp. Add code for shifting fixnums right, to avoid a round trip through libgmp. (Flsh): Remove; moved to lisp/subr.el. * test/lisp/international/ccl-tests.el (shift): Test for traditional lsh behavior, instead of assuming lsh is like ash when bignums are present. * test/src/data-tests.el (data-tests-logand) (data-tests-logior, data-tests-logxor, data-tests-ash-lsh): New tests.

* | | Remove more traces of misc (Bug#32405)Paul Eggert2018-08-141-17/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove misc-objects-consed and the misc component of memory-use-count, since misc objects no longer exist. * doc/lispref/internals.texi, etc/NEWS: Mention this, and adjust better to recent removal of misc objects. * src/alloc.c (MEM_TYPE_MISC): Remove; no longer used.

* | | Turn misc objects into pseudovectorsPaul Eggert2018-08-111-10/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate the category of miscellaneous objects, and turn all such objects into pseudovectors. The immediate motivation for this change is to free up an enum Lisp_Type tag value, a scarce resource that can be better used elsewhere. However, this change is worthwhile in its own right, as it improves performance slightly on my platform, 0.3% faster for 'make compile-always' on Fedora 28, and it simplifies the garbage collector and interpreter (Bug#32405). * doc/lispref/internals.texi (Garbage Collection): * etc/NEWS: Document change to garbage-collect return value. * src/alloc.c (total_markers, total_free_markers): (union aligned_Lisp_Misc, MARKER_BLOCK_SIZE) (struct marker_block, marker_block, marker_block_index) (misc_free_list, allocate_misc, live_misc_holding) (live_misc_p, sweep_misc): * src/lisp.h (lisp_h_MARKERP, lisp_h_MISCP, MARKERP, MISCP) (Lisp_Misc, enum Lisp_Misc_Type, Lisp_Misc_Free) (Lisp_Misc_Marker, Lisp_Misc_Overlay, Lisp_Misc_Finalizer) (Lisp_Misc_Ptr, Lisp_Misc_User_Ptr, Lisp_Misc_Limit) (Lisp_Misc_Bignum) (XSETMISC, struct Lisp_Misc_Any, XMISCANY, XMISCTYPE) (struct Lisp_Free, union Lisp_Misc, XMISC): Remove.

All uses changed.

* | | | %o and %x can now format signed integersPaul Eggert2018-07-261-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optionally treat integers as signed numbers with %o and %x format specifiers, instead of treating them as a machine-dependent two’s complement representation. This option is more machine-independent, allows formats like "#x%x" to be useful for reading later, and is better-insulated for future changes involving bignums. Setting the new variable ‘binary-as-unsigned’ to nil enables the new behavior (Bug#32252). This is a simplified version of the change proposed in: https://lists.gnu.org/r/emacs-devel/2018-07/msg00763.html I simplified that proposal by omitting bitwidth modifiers, as I could not find an any example uses in the Emacs source code that needed them and doing them correctly would have been quite a bit more work for apparently little benefit. * doc/lispref/strings.texi (Formatting Strings): Document that %x and %o format negative integers in a platform-dependent way. Also, document how to format numbers so that the same values can be read back in. * etc/NEWS: Document the change. * src/editfns.c (styled_format): Treat integers as signed numbers even with %o and %x, if binary-as-unsigned is nil. Support the + and space flags with %o and %x, since they’re about signs. (syms_of_editfns): New variable binary-as-unsigned. * test/src/editfns-tests.el (read-large-integer): Test that maximal integers can be read after printing with all integer formats, if binary-as-unsigned is nil.
