Fix hash tables, #'member*, #'assoc*, #'eql compiler macros if bignums lisp/ChangeLog addition: 2010-01-24 Aidan Kehoe <kehoea@parhasard.net> Correct the semantics of #'member*, #'eql, #'assoc* in the presence of bignums; change the integerp byte code to fixnump semantics. * bytecomp.el (fixnump, integerp, byte-compile-integerp): Change the integerp byte code to fixnump; add a byte-compile method to integerp using fixnump and numberp and avoiding a funcall most of the time, since in the non-core contexts where integerp is used, it's mostly distinguishing between fixnums and things that are not numbers at all. * byte-optimize.el (side-effect-free-fns, byte-after-unbind-ops) (byte-compile-side-effect-and-error-free-ops): Replace the integerp bytecode with fixnump; add fixnump to the side-effect-free-fns. Add the other extended number type predicates to the list in passing. * obsolete.el (floatp-safe): Mark this as obsolete. * cl.el (eql): Go into more detail in the docstring here. Don't bother checking whether both arguments are numbers; one is enough, #'equal will fail correctly if they have distinct types. (subst): Replace a call to #'integerp (deciding whether to use #'memq or not) with one to #'fixnump. Delete most-positive-fixnum, most-negative-fixnum from this file; they're now always in C, so they can't be modified from Lisp. * cl-seq.el (member*, assoc*, rassoc*): Correct these functions in the presence of bignums. * cl-macs.el (cl-make-type-test): The type test for a fixnum is now fixnump. Ditch floatp-safe, use floatp instead. (eql): Correct this compiler macro in the presence of bignums. (assoc*): Correct this compiler macro in the presence of bignums. * simple.el (undo): Change #'integerp to #'fixnump here, since we use #'delq with the same value as ELT a few lines down. src/ChangeLog addition: 2010-01-24 Aidan Kehoe <kehoea@parhasard.net> Fix problems with #'eql, extended number types, and the hash table implementation; change the Bintegerp bytecode to fixnump semantics even on bignum builds, since #'integerp can have a fast implementation in terms of #'fixnump for most of its extant uses, but not vice-versa. * lisp.h: Always #include number.h; we want the macros provided in it, even if the various number types are not available. * number.h (NON_FIXNUM_NUMBER_P): New macro, giving 1 when its argument is of non-immediate number type. Equivalent to FLOATP if WITH_NUMBER_TYPES is not defined. * elhash.c (lisp_object_eql_equal, lisp_object_eql_hash): Use NON_FIXNUM_NUMBER_P in these functions, instead of FLOATP, giving more correct behaviour in the presence of the extended number types. * bytecode.c (Bfixnump, execute_optimized_program): Rename Bintegerp to Bfixnump; change its semantics to reflect the new name on builds with bignum support. * data.c (Ffixnump, Fintegerp, syms_of_data, vars_of_data): Always make #'fixnump available, even on non-BIGNUM builds; always implement #'integerp in this file, even on BIGNUM builds. Move most-positive-fixnum, most-negative-fixnum here from number.c, so they are Lisp constants even on builds without number types, and attempts to change or bind them error. Use the NUMBERP and INTEGERP macros even on builds without extended number types. * data.c (fixnum_char_or_marker_to_int): Rename this function from integer_char_or_marker_to_int, to better reflect the arguments it accepts. * number.c (Fevenp, Foddp, syms_of_number): Never provide #'integerp in this file. Remove #'oddp, #'evenp; their implementations are overridden by those in cl.el. * number.c (vars_of_number): most-positive-fixnum, most-negative-fixnum are no longer here. man/ChangeLog addition: 2010-01-23 Aidan Kehoe <kehoea@parhasard.net> Generally: be careful to say fixnum, not integer, when talking about fixed-precision integral types. I'm sure I've missed instances, both here and in the docstrings, but this is a decent start. * lispref/text.texi (Columns): Document where only fixnums, not integers generally, are accepted. (Registers): Remove some ancient char-int confoundance here. * lispref/strings.texi (Creating Strings, Creating Strings): Be more exact in describing where fixnums but not integers in general are accepted. (Creating Strings): Use a more contemporary example to illustrate how concat deals with lists including integers about #xFF. Delete some obsolete documentation on same. (Char Table Types): Document that only fixnums are accepted as values in syntax tables. * lispref/searching.texi (String Search, Search and Replace): Be exact in describing where fixnums but not integers in general are accepted. * lispref/range-tables.texi (Range Tables): Be exact in describing them; only fixnums are accepted to describe ranges. * lispref/os.texi (Killing XEmacs, User Identification) (Time of Day, Time Conversion): Be more exact about using fixnum where only fixed-precision integers are accepted. * lispref/objects.texi (Integer Type): Be more exact (and up-to-date) about the possible values for integers. Cross-reference to documentation of the bignum extension. (Equality Predicates): (Range Table Type): (Array Type): Use fixnum, not integer, to describe a fixed-precision integer. (Syntax Table Type): Correct some English syntax here. * lispref/numbers.texi (Numbers): Change the phrasing here to use fixnum to mean the fixed-precision integers normal in emacs. Document that our terminology deviates from that of Common Lisp, and that we're working on it. (Compatibility Issues): Reiterate the Common Lisp versus Emacs Lisp compatibility issues. (Comparison of Numbers, Arithmetic Operations): * lispref/commands.texi (Command Loop Info, Working With Events): * lispref/buffers.texi (Modification Time): Be more exact in describing where fixnums but not integers in general are accepted.

;;; Commentary:

;; The following commentary is completely out of date.  I would like to
;; delete it, but it serves as a useful reminder as to how things used to
;; work.

;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
;; Special formatting conventions are used in this file!

;; a backslash-newline is used at the beginning of a documentation string
;; when that string should be stored in the file lib-src/DOCnnn, not in core.

;; Such strings read into Lisp as numbers (during the pure-loading phase).

;; But you must obey certain rules to make sure the string is understood
;; and goes into lib-src/DOCnnn properly.  Otherwise, the string will not go
;; anywhere!

;; The doc string must appear in the standard place in a call to
;; defun, autoload, defvar or defconst.  No Lisp macros are recognized.
;; The open-paren starting the definition must appear in column 0.

;; In defvar and defconst, there is an additional rule:
;; The double-quote that starts the string must be on the same
;; line as the defvar or defconst.
;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

;; **********************************************************************
;; You should never need to write autoloads by hand and put them here.

;; It is no longer necessary.  Instead use autoload.el to maintain them
;; for you.  Just insert ";;;###autoload" before defuns or defmacros you
;; want to be autoloaded, or other forms you want copied into loaddefs.el
;; (defvars, key definitions, etc.).  For example, 
;;	;;;###autoload
;;	(defun foobar () ....)
;;	;;;###autoload (define-key global-map "f" 'foobar)
;;	;;;###autoload
;;	(defvar foobar-var nil "\
;;	This is foobar-var's doc-string.")

;; Then do M-x update-file-autoloads on the file to update loaddefs.el.

;; You can also use M-x update-directory-autoloads to update the autoloads
;; in loaddefs.el for all .el files in the lisp/ directory, or M-x
;; update-autoloads-here to update the autoloads for each file that
;; already has an autoload section in this file.
