3 * Modified options by changing macro TOTAL_POSITIONS to GET_CHARSET_SIZE
4 and SET_CHARSET_SIZE. These two routines now either return
| 3 * src/version.cc (version_string): Remove the "(C++ version)" suffix.
4 It's redundant: the early C versions of gperf are called cperf.
5 Reported by Karl Berry.
6 * src/option.cc (Options::operator()): Trim the output of "gperf -v".

8Thu Apr 16 13:22:16 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
9
10 * lib/Makefile.in, src/Makefile.in: Don't use $(TARGET_ARCH).
11 Solaris "make" sets it to a value not understood by "cc".
12
13Wed Apr 15 23:52:14 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
14
15 * lib/Makefile.in, src/Makefile.in: Don't use implicit rules. Don't
16 use $<. AIX "make" and OSF/1 "make" have problems with both.
17 * src/gen-perf.cc, src/key-list.cc: Cast free() argument to char*,
18 otherwise it doesn't compile on SunOS 4.
19 * src/key-list.h: Declare structs outside of other declarations,
20 needed for OSF/1 cxx 5.5.
21 * lib/getopt.h: Use prototypes if __STDC__ || __cplusplus.
22 Don't give a prototype for getopt(), to avoid error on SunOS 4.
23 * lib/getopt.c: Declare strncmp, to avoid warnings.
24
25Tue Apr 14 23:24:07 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
26
27 * lib/GetOpt.{h,cc}: Remove files.
28 * lib/getopt.{h,c}, lib/getopt1.c: New files, from GNU libc.
29 * lib/configure.in (AC_INIT): Search for hash.cc, not GetOpt.cc.
30 * lib/Makefile.in (OBJECTS): Remove GetOpt.o, add getopt.o, getopt1.o.
31 (getopt.o, getopt1.o, hash.o): Use explicit building rules. Some
32 "make"s don't support to have both implicit rules for "%.o : %.c"
33 and "%.o : %.cc" in the same Makefile.
34 * lib/hash.{h,cc}: Remove #pragma; there are no templates here.
35 * src/option.h (Options::usage): Remove.
36 (Options::short_usage, Options::long_usage): Declare.
37 * src/option.cc (Options::usage): Remove.
38 (Options::short_usage, Options::long_usage): New functions.
39 (long_options): New array.
40 (Options::operator()): Use getopt_long instead of GetOpt::operator(),
41 change all references to GetOpt members.
42
43 * src/std-err.{h,cc}: Remove files.
44 * src/gen-perf.cc, src/key-list.cc, list-node.cc, new.cc, options.cc:
45 Call fprintf(stderr) instead of Std_Err::report_error().
46 * src/key-list.h, src/list-node.h, src/options.h: Don't use class
47 Std_Err any more.
48 * src/option.cc (program_name): New variable.
49 * src/Makefile.in: Remove STD_ERR_H.
50 (OBJECTS): Remove std-err.o.
51
52Mon Mar 23 01:03:35 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
53
54 * aclocal.m4, {lib,src,tests}/configure.in: Remove CL_CC_WORKS and
55 CL_CXX_WORKS, already contained in autoconf 2.12.
56
57 * src/gen-perf.cc, src/key-list.cc: Move some code from
58 Gen_Perf::Gen_Perf() to Key_List::output().
59 * src/Makefile.in: Update dependencies.
60
61 * src/options.{h,cc}: Remove option "-p".
62 * src/key-list.cc (Key_List::set_output_types): Rewrite.
63 (default_array_type, default_return_type): Remove.
64 * src/key-list.cc: Adjust "const" handling.
65 + With option "-t" [TYPE], don't emit wrong code if there is no
66 space before the struct's opening brace.
67
68Sun Mar 22 16:59:15 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
69
70 * src/key-list.{h,cc}: Completely reorganized the output routines.
71 Rewrote from scratch the output_switch() function. Use classes
72 (Output_Constants, Output_Expr, Output_Compare) for abstraction.
73 In particular:
74 + Don't emit trailing whitespace and spurious blank lines.
75 + Adjust indentation of the arrays.
76 + Don't emit commas at the end of array initializers and
77 struct initializers.
78 + With option "-l" [LENTABLE], compare the length before
79 fetching the word from memory.
80 + With option "-S" [SWITCH], emit the comparison code just once,
81 not once in every switch statement.
82 + With option "-S" [SWITCH], choose the right switch statement
83 through a binary search, not a linear search.
84 + With option "-S" [SWITCH], emit straightforward comparisons
85 instead of switch statements with just one "case" label.
86 + With options "-S -p -t" [SWITCH, POINTER, TYPE], don't emit
87 spurious empty elements at the beginning of the wordlist array.
88 + With option "-D" [DUP] and not option "-S" [SWITCH], if there
89 is no more room for duplicate entries in the lookup array,
90 don't call `assert (i != 0)'. Instead, make the array larger :-)
91 + With option "-D" [DUP], if there are no duplicates, don't
92 automatically fall back to the non-"-D" algorithm. If the user
93 wants the non-"-D" algorithm, he can just not specify "-D".
94 + With option "-D" [DUP] and either options "-p -t" [POINTER, TYPE]
95 or not option "-S" [SWITCH], don't emit spurious empty elements
96 at the beginning of the wordlist array.
97 + With option "-D" [DUP], simplify the detection and processing
98 of duplicate entries in the lookup array.
99 + With options "-D -l" [DUP, LENTABLE] and not option "-S" [SWITCH],
100 don't forget to emit the lengthtable array.
101 + With options "-D -l -S" [DUP, LENTABLE, SWITCH], don't forget to
102 compare the lengths before comparing the strings.
103
104 * src/gen-perf.cc: No need to include <assert.h>.
105 * src/options.cc: Likewise.
106
107 * src/options.cc: Don't use `errno' after freopen failed.
108 * src/std-err.cc: `report_error' doesn't call strerror(errno) any
109 more. No need to include <string.h> and <errno.h>.
110
111 * tests/Makefile.in (check-*): Any difference between .exp and .out
112 is a failure. Don't ignore whitespace differences.
113
114 * tests/Makefile.in (check-lang-syntax): Add some more checks.
115
116Fri Mar 20 00:54:54 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
117
118 * tests/jscript.gperf: Renamed from tests/javascript.gperf, because
119 of Minix and SVR2 14-character filename limit.
120 * src/key-list.cc (output_string): New function.
121 (Key_List::output_switch, Key_List::output_keyword_table): Call it.
122
123 * src/options.{h,icc,cc} (get_wordlist_name): New function. Add
124 option -W.
125 * src/key-list.cc (Key_List::output_switch,
126 Key_List::output_keyword_table, Key_List::output_lookup_function):
127 Use it.
128 Patch from William Bader <wbader@CSEE.Lehigh.Edu>.
129
130 * src/version.cc: Bump version number directly from 2.5 to 2.7,
131 because Schmidt's last release from 1991 carries version number 2.6.
132
133Tue Jul 30 00:02:39 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
134
135 * Fixed a small bug in the Key_List::output_keyword_table routine
136 that caused an extra newline to be printed if there where no
137 leading blank entries... (who cares, right?!)
138
139Mon Jul 29 22:05:40 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
140
141 * Modified the handling of the -E (emit enums rather than
142 #defines) option in conjunction with the -G option. Now, if -G
143 and -E are given the enums are generated outside the lookup
144 function, rather than within it!
145
146Mon Apr 8 18:17:04 1991 Doug Schmidt (schmidt at net4.ics.uci.edu)
147
148 * Yucko, there was a bug in the handling of -c (and of course the
149 new -I command in key-list.cc). Apparently when I added the
150 super-duper hack that provided support for duplicate keys I
151 forgot to update the strcmp output...
152
153Mon Mar 9 02:19:04 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
154

158 * Autoconf based configuration. Rewrote all configure.in's. Added
159 aclocal.m4, with macros from CLISP and CLN. Added Makefile.devel.

205 `char *' to `const char *'.
206 * src/key-list.cc: Change "pretty gross" assignment.
207 * src/key-list.cc: Don't use `alloca', HP-UX CC lacks it.
208 * lib/GetOpt.cc: Likewise.

286
287 * src/Makefile.in ($(TARGETPROG)): Link with $(LDFLAGS).

308
309Mon May 30 17:29:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
310
311 * Makefile.in (src_all, install): Make sure to add '/' after

356 Don't use variable-size stack arrays, unless compiled by g++.
357
358Tue May 4 14:08:44 1993 Per Bothner (bothner@cygnus.com)
359
360 Changes (mostly from Peter Schauer) to permit compilation
361 using cfront 3.0 and otherwise be ARM-conforming.
362 * src/key-list.h: class Key_List must use public derivation
363 of base class Std_Err (because Gen_Perf::operator() in gen-perf.cc
364 calls Std_Err::report_error).
365 * src/gen-perf.cc (Gen_Perf::affects_prev), src/hash-table.cc
366 (Hash_Table::operator()): Don't use gcc-specific 2-operand

409Thu Dec 3 19:34:12 1992 Per Bothner (bothner@cygnus.com)
410
411 * Makefile.in (distclean, realclean): Don't delete
412 Makefile before recursing.
413
414Fri Nov 6 13:41:49 1992 Per Bothner (bothner@rtl.cygnus.com)
415
416 * key-list.{h,cc}: Remove MAX_INT (and similar) constant
417 fields from Key_List class, and use INT_MAX (etc) from limits.h.
418 * key-list.{h,cc}, options.{h,cc}, vectors.h: Removed all
419 uses of initialized const fields, as they are non-standard
420 - and their use was easy to do away with. Mostly, just
421 made the constants static non-fields in the .cc file.
422
423Mon Nov 2 13:10:11 1992 Per Bothner (bothner@cygnus.com)
424
425 * tests/Makefile.in: When generating cinset.c, don't pass -C,
426 since -C assumes an ANSI compiler. Add the -C flag (with -a)
427 when generating test.out.3 instead.
428 * tests/expected.out.3: Update accordingly.
429
430Wed Aug 12 11:47:54 1992 Per Bothner (bothner@cygnus.com)
431
432 * Makefile.in: Factor out common flags into $(FLAGS_TO_PASS).
433 * Makefile.in: 'install-info' depends on gperf.info.
434
435Mon Aug 10 11:39:52 1992 Ian Lance Taylor (ian@dumbest.cygnus.com)
436
437 * Makefile.in, src/Makefile.in: always create installation
438 directories.
439
440Mon Jul 20 15:33:21 1992 Mike Stump (mrs@cygnus.com)
441
442 * src/new.cc (operator new): Add cast from void * to char *,
443 since it is not a standard conversion.
444
445Wed Jun 17 16:25:30 1992 Per Bothner (bothner@rtl.cygnus.com)
446
447 * src/gen-perf.cc: #include <_G_config.h> for _G_SYSV.
448 * src/key-list.cc: alloca() hair.
449 * src/main.cc (main): Only call getrlimit if _G_HAVE_SYS_RESOURCE.
450 * Makefile,in, {src,test}/Makefile.in: Fix *clean rules.
451
452Fri May 29 13:21:13 1992 Per Bothner (bothner@rtl.cygnus.com)
453
454 * src/gen-perf.cc: Replace USG -> _G_SYSV.
455
456Thu May 14 13:58:36 1992 Per Bothner (bothner@rtl.cygnus.com)
457
458 * src/Makefile.in: Don't pass obsolete flag -DUNLIMIT_STACK.
459 * tests/Makefile.in (clean): Fix.
460
461Sat Mar 7 00:03:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
462
463 * gperf.texinfo: added menu item hook.
464
465Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
466
467 * Makefile.in, configure.in: removed traces of namesubdir,
468 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
469 copyrights to '92, changed some from Cygnus to FSF.
470
471Sun Jan 26 19:21:58 1992 Per Bothner (bothner at cygnus.com)
472
473 * tests/Makefile.in: Use re-directed stdin instead of file
474 name in argv. This allows us to remove the filename
475 from the output, the expected output, and hence the diffs.
476 (Note that the input file is in $(srcdir), which we cannot
477 place in the expected out files.)
478 * tests/expected.out.[1235]: Edit out input filename,
479 to match new output.
480
481Thu Jun 28 16:17:27 1990 Doug Schmidt (schmidt at brilliant)
482
483 * Wow, first fix on the new job! There was a dumb error
484 in Key_List::output_lookup_function, where I printed the
485 string "&wordlist[key]" instead of the correct "&wordlist[index]".
486
487 * Added a couple of #ifdefs for USG support.
488
489Sun Jun 3 17:16:36 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
490
491 * Updated the version number to 2.5 and sent to Doug Lea for release
492 with the latest GNU libg++.
493
494 * Changed the error handling when a keyword file cannot be opened
495 (now calls perror).
496
497Wed May 30 14:49:40 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
498
499 * Instrumented the source code with trace statements automagically
500 inserted using my new automated trace instrumentation tool!
501
502Wed May 9 11:47:41 1990 Doug Schmidt (schmidt at siam.ics.uci.edu)
503
504 * Really fixed the previous bug. Turns out that a small amount
505 of logic had to be duplicated to handle static links that occur
506 as part of dynamic link chains. What a pain!!!
507
508Tue May 8 23:11:44 1990 Doug Schmidt (schmidt at siam.ics.uci.edu)
509
510 * Fixed a stupid bug in Key_List::output_lookup_array that was
511 causing incorrect counts to be generated when there were both
512 static and dynamic links occurring for the same hash value.
513 Also simplified the code that performs the logic in this routine.
514
515Mon Apr 30 17:37:24 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
516
517 * Fixed stupid bug in Key_List::output_lookup_array that was
518 making the generated lookup[] array contain `chars' even
519 when the values stored in the chars are greater than 127!
520
521 * Changed the behavior of the -G (global table) option so that it
522 will output the `length[]' array in the global scope along with
523 the `word_list[]' array.
524
525 * Fixed a stupid bug in Key_List::output_lookup_function that
526 would always output the complicated `duplicate-handling' lookup
527 logic, even when there were no duplicates in the input!
528
529 * Yikes, had to modify a bunch of stuff in key-list.cc to correctly
530 handle duplicate entries. Changed the generated code so that
531 the MIN_HASH_VALUE is no longer subtracted off when calculating
532 the hash value for a keyword. This required changing some other
533 code by substituting MAX_HASH_VALUE for TOTAL_KEYS in several places.
534 Finally, this means that the generated tables may contain leading
535 null entries, but I suppose it is better to trade-off space to get
536 faster performance...
537
538Mon Mar 26 13:08:43 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
539
540 * Updated version number to 2.4 to reflect the latest changes.
541
542 * Changed the main program so that it always prints out gperf's
543 execution timings to the generated output file.
544
545Sun Mar 25 12:39:30 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
546
547 * Added the -Z option so that users can specify the name of the
548 generated class explicitly. Updated documentation to reflect
549 this change.
550
551 * Modified the generated C++ class interface so that the functions
552 are declared static (to remove the overhead of passing the `this'
553 pointer). This means that operator()() can no longer be used,
554 since it only works on non-static member functions.
555 Also changed things so that there is no constructor (why waste
556 the extra call, when it doesn't do anything, eh?)
557
558 * Modified the behavior of Key_List::output when the -L C++ option
559 is enabled. Previously the code generated use const data members
560 to record MIN_WORD_LENGTH, MIN_HASH_VALUE, etc. However, as
561 pointed out by James Clark this may result in suboptimal behavior
562 on the part of C++ compilers that can't inline these values.
563 Therefore, the new behavior is identical to what happens with
564 -L C, i.e., either #defines or function-specific enums are used.
565 Why sacrifice speed for some abstract notion of `code purity?' ;-)
566
567Tue Mar 6 18:17:42 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
568
569 * Added the -E option that defines constant values using an enum
570 local to the lookup function rather than with #defines. This
571 also means that different lookup functions can reside in the
572 same file. Thanks to James Clark (jjc@ai.mit.edu).
573
574Sat Mar 3 20:19:00 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
575
576 * Added a special case to key_list::output_switch that doesn't
577 generate extra comparisons when the `-S' is given an argument
578 of 1 (the normal case). This should speed up the generated
579 code output a tad...
580
581Fri Feb 23 14:21:28 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
582
583 * Renamed all instances of member function get_keysig_size
584 to get_max_keysig_size, since this is more precise...
585
586 * Changed all occurrences of charset to keysig (stands for ``key
587 signature'') to reflect the new naming convention used in the
588 USENIX paper.
589
590Thu Feb 22 11:28:36 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
591
592 * Changed the name of the generated associated values table from
593 asso_value to asso_values to reflect conventions in the USENIX
594 C++ paper.
595
596Thu Feb 15 23:29:03 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
597
598 * Updated the gperf.texinfo file to fix some formatting problems
599 that had crept in since last time.
600
601Wed Feb 14 23:27:24 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
602
603 * Fixed stupid bug in key-list.cc (get_special_input), wher
604 gperf replaced each '%' with the succeeding character.
605
606 * Added support for multiple target language generation. Currently
607 handled languages are C and C++, with C as the default. Updated
608 documentation and option handler to reflect the changes.
609
610 * Added a global destructor to new.cc and removed the #ifdef, since
611 the bloody thing now works with libg++.
612
613Mon Feb 14 13:00:00 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
614
615 * Found out that my gperf paper was accepted at the upcoming
616 USENIX C++ Conference in San Francisco. Yow!
617
618Tue Jan 30 09:00:29 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
619
620 * #ifdef'd out the new.cc memory allocator, since there are
621 problems with this and the libg++ stuff.
622
623 * Changed key-list.h so that class Vectors is a public (rather
624 than private) base class for class Key_List. The previous
625 form was illegal C++, but wasn't being caught by the old
626 g++ compiler. Should work now... ;-)
627
628Sun Dec 10 14:08:23 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
629
630 * Added several changes from rfg@ics.uci.edu. These changes
631 help to automate the build process.
632
633Wed Nov 15 15:49:33 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
634
635 * Removed conditional compilation for GATHER_STATISTICS. There's
636 really no good reason to avoid collecting this info at run-time,
637 since that section of code is *hardly* the bottleneck... ;-)
638
639 * Simplified the C output routines in Key_List::set_output_types
640 and Key_List::output_keyword_table a bit in order to
641 speed-up and clean up the code generation.
642
643 * Modified function Key_List::get_special_input so that it does
644 not try to `delete' a buffer that turned out to be too short.
645 This is important since the new memory management scheme
646 does not handle deletions. However, adding a small amount of
647 garbage won't hurt anything, since we generally don't do this
648 operation more than a couple times *at most*!
649
650 * Created a new file (new.cc) which includes my own overloaded
651 operator new. This function should dramatically reduce the
652 number of calls to malloc since it grabs large chunks and
653 doles them out in small pieces. As a result of this change
654 the class-specific `operator new' was removed from class List_Node.
655
656Tue Nov 14 21:45:30 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
657
658 * Continued to refine the great hack. The latest trick is to
659 try and replace most uses of dynamic memory (i.e., calls to
660 new) with uses of gcc dynamic arrays (i.e., an alloca solution).
661 This makes life much easier for the overall process-size, since
662 it reduces the amount of overhead for memory management. As a
663 side-effect from this change there is no reason to have the
664 Bool_Array::dispose member function, so it's outta here!
665
666 * Fixed a stupid bug that was an disaster waiting to happen...
667 Instead of making the boolean array large enough to index
668 max_hash_value it was only large enough to index max_hash_value
669 - 1. Once again, an off-by-one mistake in C/C++!!!!
670
671Mon Nov 13 19:38:27 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
672
673 * Added the final great hack! This allows us to generate hash tables
674 for near-perfect hash functions that contain duplicates, *without*
675 having to use switch statements! Since many compilers die on large
676 switch statements this feature is essential. Furthermore, it appears
677 that the generated code is often *smaller* than that put out by
678 compilers, even though a large, sparse array must be created.
679 Here's the general idea:
680
681 a. Generate the wordlist as a contiguous block of keywords,
682 just as before when using a switch statement. This
683 wordlist *must* be sorted by hash value.
684
685 b. Generate the lookup array, which is an array of signed
686 {chars,shorts,ints}, (which ever allows full coverage of
687 the wordlist dimensions). If the value v, where v =
688 lookup[hash(str,len)], is >= 0 and < TOTAL_KEYWORDS, then we
689 simply use this result as a direct access into the wordlist
690 array to snag the keyword for comparison.
691
692 c. Otherwise, if v is < -TOTAL_KEYWORDS or > TOTAL_KEYWORDS
693 this is an indication that we'll need to search through
694 some number of duplicates hash values. Using a hash
695 linking scheme we'd then index into a different part of
696 the hash table that provides the starting index and total
697 length of the duplicate entries to find via linear search!
698
699Sun Nov 12 13:48:10 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
700
701 * Simplified Key_List::output_min_max considerably by recognizing
702 that since the keyword list was already sorted by hash value finding
703 the min and max values is trivial!
704
705 * Improved the debugging diagnostics considerably in classes Key_List,
706 Hash_Table, and Gen_Perf.
707
708 * Modified the `-s' option so that a negative argument is now
709 interpreted to mean `allow the maximum associated value to be
710 about x times *smaller* than the number of input keys.' This
711 should help prevent massive explosion of generated hash table
712 size for large keysets.
713
714Sat Nov 11 11:31:13 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
715
716 * Added a field in class Key_List that counts the total number
717 of duplicate keywords, both static and dynamic.
718
719 * Added a new member function Bool_Array that deletes the dynamic
720 memory allocated to Bool_Array::storage_array. This space may
721 be needed for subsequent options, so it made sense to free it as
722 soon as possible...
723
724 * Renamed file/class Alpha_Vectors to Vectors, to avoid problems
725 with 14 character length filenames on SYSV. Also changed file
726 adapredefined.gperf to adadefs.gperf in the ./tests directory.
727
728 * Modified class Options by changing the member function
729 Options::total_positions to Options::get_charset_size and
730 Options::set_charset_size. These two routines now either return
|
5 the total charset size *or* the length of the largest keyword
6 if the user specifies the -k'*' (ALLCHARS) option. This change
7 cleans up client code.

31 should silence broken C compilers for a while!

47 The user can now specify the number of switch statements to generate
48 via an argument to the -S option, i.e., -S1 means `generate 1
49 switch statement with all keywords in it,' -S2 means generate
50 2 switch statements with 1/2 the elements in each one, etc.
51 Hopefully this will fix the problem with C compilers not being
52 able to generate code for giant switch statements (but don't
53 hold your breath!)

81 * Modified LIST_NODE so that the char *char_set field is redeclared
82 as char char_set[1] and placed at the bottom of the struct. This
83 enables us to play the old `variable-length string in the struct
84 trick' (third time I fell for it this week, chief!). The
85 main purpose of this is to remove n calls to buffered_malloc,
86 where n is the number of keywords.
87
88 * Added a new function to xmalloc.c called buffered_malloc. This
89 reduces the number of calls to malloc by grabbing large chunks
90 of memory and doling them out in small pieces. Almost all uses
91 of xmalloc were replaced with calls to buffered_malloc ().

114 us to get free up the large dynamic memory as soon as it is no
115 longer necessary. Also moved the hash_table destructor from

117 the same purpose, i.e., we can free up the space immediately.

134 the variable `perfect.fewest_collisions is no longer initialized
135 with the length of the keyword list. Instead it starts out at
136 0 and is incremented by 1 every time change () is called.
137 The rationale for this behavior is that there are times when a
138 collision causes the number of duplicates (collisions) to
139 increase by a large amount when it would presumably just have
140 gone up by 1 if none of the asso_values were changed. That is,

142 to 1+(previous value of fewest_hits) instead of to the number of
143 keys. Thanks again, Nels.

856 A right paren was placed at the wrong location, which broke

|
178 5. Finally split the huge help string into two parts. This keeps
179 breaking compilers with static limits on the length of tokens...
| 861 5. Changed the behavior of Key_List::read_keys so that it would
862 honor -D unequivocally, i.e., it doesn't try to turn off dup
863 handling if the user requests it, even if there are no
864 immediate links in the keyfile input.

181 when searching for a way to resolve collisions.'

886 everytime the previous buffer runs out, as a heuristic

892 incorporation into the long-awaited `official' libg++ 1.36
893 release!

896 was fixed. This problem caused gperf to seg fault when
897 the -k* option was given and the keyfile file had long
898 keywords.
899
900 * Modified Key_List::print_hash_function so that it output
901 max_hash_value + 1 (rather than just max_hash_value) for
902 any associated value entries that don't correspond to
903 keyword charset characters. This should speed up rejection
904 of non-keyword strings a little in some cases.
905
906Sat Oct 21 19:28:36 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
907
908 * Fixed Key_List::print_hash_function so that it no longer output
909 things like `return 0 + ...' Although this probably gets
910 optimized away by even the worst C compilers there isn't any
911 point tempting fate... ;-)
912
913 * Fixed class List_Node's constructor so that it wouldn't a priori
914 refuse to consider trying to hash keys whose length is less
915 than the smallest user-specified key position. It turns out
916 this is not a problem unless the user also specifies the -n
917 (NOLENGTH) option, in which case such keys most likely
918 don't have a prayer of being hashed correctly!
919
920 * Changed the name of the generated lookup table from `Hash_Table'
921 to `asso_value' to be consistent with the gperf paper.
922
923Tue Oct 17 14:19:48 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
924
925 * Added a flag GATHER_STATISTICS in the Makefile. If defined
926 during compilation this turns on certain collection facilities
927 that track the performance of gperf during its execution. In
928 particular, I want to see how many collisions occur for the
929 double hashing Hash_Table.
930
931 * Added a safety check so that we don't screw up if the total
932 number of `resets' of the Bool_Array exceeds MAX_INT. Since
933 this number is around 2^31 it is unlikely that this would ever
934 occur for most input, but why take the risk?
935
936 * Changed the behavior for the -a (ANSI) option so that the
|
206 generated prototypes use int rather than size_t for the LEN
207 parameter. It was too ugly having to #include <stddef.h> all

210 * Added a majorly neat hack to Bool_Array, suggested by rfg.
211 The basic idea was to throw away the Ullman array technique.
212 The Ullman array was used to remove the need to reinitialize all
213 the Bool_Array elements to zero everytime we needed to determine
214 whether there were duplicate hash values in the keyword list.
215 The current trick uses an `iteration number' scheme, which takes
216 about 1/3 the space and reduces the overall program running a
217 time by about 20 percent for large input! The hack works as
218 follows:

224 kicking the iteration count by 1.
225 3. When it comes time to check whether a hash value is currently
226 in the boolean array we simply check its index location. If
227 the value stored there is *not* equal to the current iteration
228 number then the item is clearly *not* in the set. In that
229 case we assign the iteration number to that array's index
230 location for future reference. Otherwise, if the item at
231 the index location *is* equal to the iteration number we've
232 found a duplicate. No muss, no fuss!

1003 needs to know about the buffering scheme used to speed up
1004 dynamic memory allocation of input keywords and their

| 1010 * Decided that Obstacks had too much overhead, so they were

1063
1064 * Changed the ./tests subdirectory Makefile so that it
1065 uses $(CC) instead of gcc.

281
| 1068
|
282 * Moved comment handling from keylist.c to readline.c. This
283 simplifies the code and reduces the number of malloc calls.
284
| |
285 * Fixed a number of subtle bugs that occurred when -S was
286 combined with various and sundry options.
287
288 * Added the -G option, that makes the generated keyword table
289 a global static variable, rather than hiding it inside
290 the lookup function. This allows other functions to directly
291 access the contents in this table.
292
| 1069 * Fixed a number of subtle bugs that occurred when -S was
1070 combined with various and sundry options.
1071

294

295 * Added the "#" feature, that allows comments inside the keyword
| 1077 * Added the "#" feature, that allows comments inside the keyword
|
296 list from the input file.
| 1078 list from the input file. Comment handling takes place in readline.c.
1079 This simplifies the code and reduces the number of malloc calls.
|
297
298 * Also added the -H option (user can give the name of the hash
299 function) and the -T option (prevents the transfer of the type decl
300 to the output file, which is useful if the type is already defined
301 elsewhere).
302
| 1080
1081 * Also added the -H option (user can give the name of the hash
1082 function) and the -T option (prevents the transfer of the type decl
1083 to the output file, which is useful if the type is already defined
1084 elsewhere).

|
304
| 1087
|
305 * Added Adam de Boor's changes. Created an UNSET_OPTION macro.
| 1088 * Modified many classes so that they would inherit Std_Err as
1089 a base class. This makes things more abstract...

|
308
| 1092
|
309 * Modified option.h and option.c so that all mixed operations
310 between integers and enumerals are cast correctly to int.
311 This prevents errors in some brain-damaged C compilers.
312
313Fri Jun 16 14:13:15 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
314
| |
315 * Modified the -f (FAST) option. This now takes an argument.
316 The argument corresponds to the number of iterations used
317 to resolve collisions. -f 0 uses the length of the
318 keyword list (which is what -f did before). This makes
319 life much easier when dealing with large keyword files.
320
| 1093 * Modified the -f (FAST) option. This now takes an argument.
1094 The argument corresponds to the number of iterations used

322
| 1100
|
323 * Updated to version 1.8 in preparation to release to Doug Lea
324 and FSF.
325
| |
326 * Added the -c (comparison) option. Enabling this
327 will use the strncmp function for string comparisons.
328 The default is to use strcmp.
329
| 1101 * Added the -c (comparison) option. Enabling this
1102 will use the strncmp function for string comparisons.
1103 The default is to use strcmp.
1104
|
330Tue Jun 6 16:32:09 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
| 1105 * Fixed a typo in key_list.cc (PRINT_SWITCH). This caused
1106 faulty C code to be generated when the -D, -p, and -t
1107 options were all enabled.
|
331
| 1108
|
332 * Fixed another stupid typo in xmalloc.c (XMALLOC). I accidentally
333 left the ANSI-fied prototype in place. This obviously
334 fails on old-style C compilers.
| 1109Thu May 25 14:07:21 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
335
| 1110
|
336 * Fixed stupid typos in PRINT_SWITCH from the keylist.c. This
337 caused the -D option to produce incorrect output when used
338 in conjunction with -p and -t.
339
340 * Replaced the use of STRCMP with STRNCMP for the generated
341 C output code.
| 1111 * Once again, changed class Read_Line to overload global operator
1112 new. Hopefully, this will work...!
|

|
344
| 1115
|
345 * Added a new function (XMALLOC) and file (xmalloc.c). All
346 calls to MALLOC were replaced by calls to XMALLOC. This
347 will complain when virtual memory runs out (don't laugh,
348 this has happened!)
| 1116 * Modified Key_List::print_hash_function () so that it properly
1117 formats the associated values in the hash table according to
1118 the maximum number of digits required to represent the largest
1119 value.
|
349
| 1120
|
350Thu Jun 1 21:10:10 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
| 1121 * Removed the named return value from class Hash_Table's
1122 operator (), since this causes a seg fault when -O is enabled.
1123 No sense tripping subtle g++ bugs if we don't have to.... ;-)
|
351
| 1124
|
352 * Fixed a typo in options.c that prevented the -f option
353 from being given on the command-line.
| 1125 * Removed the operator new hack from Read_Line, since this seemed
1126 to create horrible bus error problems.
1127
1128 * Changed many class member functions and data members to be `static',
1129 if they don't manipulate this!

354
| 1132
|
355Wed May 3 17:48:02 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
| 1133 * Changed class Std_Err to use static member functions, a la
1134 Ada or Modula 2. This eliminates the need for an explicit
1135 error-handler class object.
|
356
| 1136
|
| 1137 * Added the ``named return value'' feature to Hash_Table::operator ()
1138 and Bool_Array::operator [], just for the heck of it.... ;-)
1139
1140 * Changed the previous hack in Read_Line so that we now use
1141 the overloaded global `new' instead of NEW_STRING!
1142
1143Wed May 3 17:36:55 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
1144
|
357 * Updated to version 1.7. This reflects the recent major changes
358 and the new C port.
359
| 1145 * Updated to version 1.7. This reflects the recent major changes
1146 and the new C port.
1147
|
360 * Fixed a typo in perfect.c perfect_destroy that prevented the actual
361 maximum hash table size from being printed.
| 1148 * Modified the GNU getopt.cc routine to have a class-based interface.
|
362
| 1149
|
| 1150 * Fixed a typo in Perfect.cc ~Perfect that prevented the actual maximum
1151 hash table size from being printed (maybe the stream classes
1152 weren't so bad after all.... ;-).
1153
|
363 * Added support for the -f option. This generates the perfect
364 hash function ``fast.'' It reduces the execution time of
365 gperf, at the cost of minimizing the range of hash values.
366
367Tue May 2 16:23:29 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
368
| 1154 * Added support for the -f option. This generates the perfect
1155 hash function ``fast.'' It reduces the execution time of
1156 gperf, at the cost of minimizing the range of hash values.
1157
1158Tue May 2 16:23:29 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1159
|
369 * Enabled the diagnostics dump if the debugging option is enabled.
370
371 * Removed all calls to FREE (silly to do this at program termination).
| 1160 * Added an efficiency hack to Read_Line. Instead of making
1161 a call to operator NEW (a.k.a. malloc) for each input string
1162 a new member function NEW_STRING stores a large buffer from
1163 which new strings are carved out, growing the buffer if
1164 necessary. It might be useful to add this throughout the
1165 program....
|
372
| 1166
|
| 1167 * Removed all unnecessary calls to DELETE. If the program is about
1168 to exit it is silly to waste time freeing memory.
1169
1170 * Added the GNU getopt program to the distribution. This makes
1171 GPERF portable to systems that don't include getopt in libc.
1172
1173 * Added a strcspn member to class Key_List. This also increases
1174 portability.
1175
1176 * Added the get_include_src function from keylist.c as a member
1177 function in class Key_List. Hopefully every function is
1178 now associated with a class. This aids abstraction and
1179 modularity.
1180
|
373 * Ported gperf to C. From now on both K&R C and GNU G++ versions
| 1181 * Ported gperf to C. From now on both K&R C and GNU G++ versions
|
374 will be supported.
| 1182 will be supported. There will be two ChangeLog files, one
1183 for each version of the program.

| 1185Mon May 1 16:41:45 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1186
1187 * Fixed a bug with -k'*'. This now prints out *all* the cases
1188 up to the length of the longest word in the keyword set.
1189
1190Sun Apr 30 12:15:25 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1191
1192 * Removed all use of the stream classes. Too ugly, slow, and
1193 not handled by the c++-mode formatter....
1194
1195 * Modified the handling of links (i.e., keywords that have
1196 identical hash values as other keywords). This should
1197 speed up hash function generation for keyword sets with
1198 many duplicate entries. The trick is to treat duplicate
1199 values as equivalence classes, so that each set of duplicate
1200 values is represented only once in the main list processing.
1201
1202 * Fixed some capitialization typos and indentations mistakes in
1203 Key_List::print_hash_function.
1204
1205Sat Apr 29 12:04:03 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
1206
1207 * Fixed a typo/logico in Key_List::print_switch that prevented
1208 the last keyword in the keyword list to be print out. This
1209 requires further examination.....
1210
1211 * Fixed a stupid bug in List_Node::List_node. If the -k'*' option
1212 was enabled the KEY_SET string wasn't getting terminated with
1213 '\0'!
1214
1215Fri Apr 28 12:38:35 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1216
1217 * Renamed strexp.h and strexp.cc to iterator.h and iterator.cc.
1218 Also changed the strexp class to iterator. Continued to work
1219 on style...
1220
1221 * Updated the version number to 1.6. This reflects all the
1222 recent changes.
1223
1224Thu Apr 27 00:14:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1225
1226 * Added the -D option that properly handles keyword sets that
1227 contain duplicate hash values.
1228
1229 * Continued the stylistic changes. Added the #pragma once
1230 directive to all the *.h files. Removed all #defines and
1231 replaced them with static consts. Also moved the key_sort
1232 routine from options.cc into the options class as a
1233 member function.
1234
1235Mon Apr 3 13:26:55 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
1236
1237 * Made massive stylistic changes to bring source code into
1238 conformance with GNU style guidelines.
1239
1240Thu Mar 30 23:28:45 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1241
1242 * Fixed up the output routines so that they generate code
1243 corresponding to the GNU style guidelines.
1244
1245Sat Mar 11 13:12:37 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1246
1247 * Fixed Stderr constructors so that they wouldn't try to
1248 use the base class initializer syntax for the static
1249 class variable Program_Name. G++ 1.34 is stricter in
1250 enforcing the rules!
1251
1252Fri Mar 10 11:24:14 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1253
1254 * Removed -v and ``| more'' from the Makefile to keep rfg happy...
1255
1256Thu Mar 2 12:37:30 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1257
1258 * Sent latest GNU gperf version 1.5 to Doug Lea for inclusion
1259 into libg++ 1.34. Note that there is a small bug with
1260 the new %{ ... %} source inclusion facility, since it doesn't
1261 understand comments and will barf if %{ or %} appear nested
1262 inside the outermost delimiters. This is too trivial of
1263 a defect to fix at the moment...
1264
1265Tue Feb 28 11:19:58 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1266
1267 * Added the -K option, which allows the user to provide a
1268 alternative name for the keyword structure component.
1269 The default is still ``name.''
1270
1271 * Added the LEX and YACC-like ability to include arbitrary
1272 text at the beginning of the generated C source code output.
1273 This required two new functions Get_Special_Input,
1274 Key_List::Save_Include_Src;
1275
1276 * Fixed memory allocation bug in Key_List::Set_Types.
1277 Variable Return_Type needs 1 additional location
1278 to store the "*" if the -p option is used.
1279
1280 * Added code to NULL terminate both Struct_Tag and Return_Type,
1281 *after* the strncpy (stupid mistake).
1282
1283Mon Feb 27 14:39:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1284
1285 * Added a new option -N. This allows the user to specify the
1286 name to be used for the generated lookup function. The
1287 default name is still ``in_word_set.'' This makes it
1288 possible to completely automate the perfect hash function
1289 generation process!
1290
1291Mon Feb 20 23:33:14 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1292
1293 * Corrected the Hash_Table::operator () function so that
1294 *it* is responsible for deciding when a new key has the
1295 same signature as a previously seen key. The key length
1296 information is now used internally to this function to
1297 decide whether to add to the hash table those keys with
1298 the same key sets, but different lengths. Before, this
1299 was handled by the Key_List::Read_Keys function. However,
1300 this failed to work for certain duplicate keys, since
1301 they weren't being entered into the hash table properly.
1302
1303Sun Feb 19 16:02:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1304
1305 * Modified class Options by moving the enum Option_Type out
1306 of the class. This is to satisfy the new enumeration
1307 scope rules in C++.
1308
1309Sun Jan 15 15:12:09 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1310
1311 * Incremented the version number upto 1.4 to reflect the new
1312 options that affect the generated code. Send the new
1313 distribution off to Michael for use with g++ 1.33.
1314
1315 * Added a fix to Key_List::Read_Keys so that it checks for links
1316 properly when the -n option is used. Previously, it didn't
1317 catch obvious links, which caused it to spend large amount
1318 of time searching for a solution that could never occur!
1319
1320 * Modified the Key_List data structure to record *both* the
1321 minimum and the maximum key lengths. This information
1322 is now computed in Key_List::Read_Keys, and thus
1323 Key_List::Print_Min_Max doesn't need to bother.
1324
1325 * Modifed the key position iterator scheme in options.cc to
1326 eliminate the need for member function Options::Advance.
1327 Now, the Options::Get function performs the advancement
1328 automatically, obviating the need for an extra function call.
1329
1330 * Added the new function Options::Print_Options, to print out
1331 the user-specified command line options to generated C
1332 output file.
1333
1334 * Added a new function, Key_List::Print_Keylength_Table,
1335 which creates a table of lengths for use in speeding
1336 up the keyword search. This also meant that a new
1337 option, -l (LENTABLE) is recognized. It controls
1338 whether the length table is printed and the comparison
1339 made in the generated function ``in_word_set.''
1340
1341 * Added a comment at the top of the generated C code
1342 output file that tells what version of gperf was used.
1343 Next, I'll also dump out the command line options
1344 as a comment too. Thanks to Michael Tiemann for the
1345 feedback on this.
1346
1347 * Fixed the -n option to make it work correctly with
1348 other parts of the program (most notably the Perfect::Hash
1349 function and the computation of minimum and maximum lengths.
1350
1351Fri Jan 13 21:25:27 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
1352
1353 * Realized the the need to add a test that will enable
1354 optimziation of the generated C code in the ``hash'' function
1355 by checking whether all the requested key positions are
1356 guaranteed to exist due to the comparison in `in_word_set.''
1357 I'll put this in soon....
1358
1359Thu Jan 12 20:09:21 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1360
1361 * Added pascal, modula3, and modula2 tests inputs to the
1362 Makefile
1363
1364 * Recognised that there is a bug with the -n option. However
1365 I'm too busy to fix it properly, right now. The problem
1366 is that the generated #define end up being 0, since that's
1367 my hack to make -n work. This needs complete rethinking!
1368
1369Tue Jan 10 00:08:16 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1370
1371 * Added a new option, -n, that instructs gperf to not use the
1372 length of an identifier when computing the hash functions.
1373 I'm not sure how useful this is!
1374
1375 * Retransmitted the distribution to rocky.oswego.edu. Hopefully,
1376 this will work!
1377
1378 * Began fixing the indentation and capitalization to conform
1379 to the GNU coding guidelines.
1380
1381Mon Jan 9 22:23:18 1989 Doug Schmidt (schmidt at pompe.ics.uci.edu)
1382
1383 * Fixed horrible bug in Read_Line::Readln_Aux. This was
1384 a subtle and pernicous off-by-1 error, that overwrote
1385 past the last character of the input string buffer. I
1386 think this fault was killing the vax!
1387
1388 * Yow, fixed an oversight in List_Node::List_Node, where the
1389 pointer field Next was uninitialized. Luckily, the new routine
1390 seems to return 0 filled objects the first time through!
1391
1392Sun Jan 8 13:43:14 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
1393
1394 * Modified the ``key linked'' diagnostic in Key_List::Read_Keys
1395 to be more helpful and easy to read.
1396
1397 * Fixed the List_Node::List_Node so that it would ignore trailing
1398 fields if the -t option was not enabled.
1399
1400 * Moved the List_Node declarations out of keylist.h and
1401 into a file of its own, called listnode.cc and listnode.h
1402 Made Set_Sort a member function of class List_Node.
1403
1404 * Massively updated the documentation in the gperf.texinfo file.
1405
1406 * Polished off the major revision to the print functions,
1407 added a few new tests in the Makefile to check for the
1408 validity of the program and ftp'ed the entire distribution
1409 off to Doug Lea for libg++. ( changed it to
1410 1.3 to reflect the major changes with the generated
1411 C code ).
1412
1413 * Fixed Key_List::Print_Switch to deal with the -p and -t options.
1414 This meant that the ``still-born'' function Key_List::
1415 Print_Type_Switch was superflous, so I removed it.
1416 Also, removed the restriction in Option that the -p and
1417 -t options couldn't be used simultaneously.
1418
1419 * Modified List_Node::List_Node, to perform only 1 call to
1420 ``new'' when dynamically allocating memory for the Key_Set
1421 and the Uniq_Set.
1422
1423Sat Jan 7 14:10:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
1424
1425 * Fixed a big bug with the new policy of nesting the
1426 wordlist inside of generated function ``in_word_set.''
1427 I'd forgotten to declare the wordlist array as static!
1428 ( arrgh ).
1429
1430 * Added a new function Key_List::Set_Types, that figures out
1431 the return type for generated function ``in_word_set,''
1432 the user-defined ``struct tag,'' if one is used, and also
1433 formates the array type for the static local array.
1434
1435 * Changed the print routines to take advantage of the
1436 new -p option.
1437
1438 * Began adding the hooks to allow the return of a pointer
1439 to a user defined struct location from the generated
1440 ``in_word_set'' function instead of the current 0 or 1
1441 return value. Created function Key_List::Print_Type_Switch
1442 and added option -p to class Option, allowing the user to
1443 request generation of the aforementioned pointers returned
1444 instead of booleans.
1445
1446 * Put in checks in class Option to make sure that -S and -t
1447 options are not used simultaneously. This restriction
1448 will be removed in subsequent releases, once I decide on
1449 a clean way to implement it.
1450
1451 * Sent version 1.2 to Doug Lea for possible inclusion into
1452 the libg++ distribution.
1453
1454 * Moved the static word_list array inside the generated function
1455 in_word_set. This supports better data hiding.
1456
1457 * Added a texinfo file, gperf.texinfo
1458
1459 * Revised the Makefile to cleanup the droppings from texinfo
1460 and changed the name of gperf.cc and gperf.h to perfect.cc
1461 and perfect.h.

1464
1465 * Implemented the switch statement output format. Much better
1466 for large datasets in terms of space used.
1467
1468 * Added new functions to break up the Key_List::Output function.
1469 Functions added were Key_List::Print_Switch, Key_List::Print_Min_Max,
1470 Key_List::Print_Keyword_Table, Key_List::Print_Hash_Function,
1471 and Key_List::Print_Lookup_Function. This simplifies the
1472 big mess in Key_List::Output considerably!
1473
1474 * Added switch statement option to Options, which potentially
1475 trades time for space in the generated lookup code.

1478
1479 * Released version 1.1
1480
1481 * Fixed a bug with Gperf::Merge_Set, it was skipping letters shared
1482 between the Set_1 and Set_2.
1483
1484 * Added the optimal min/max algorithm in Key_List::Output. This
1485 runs in O ( 3n/2 ), rather than O ( 2n ) time.
1486
1487 * Changed Gperf::Sort_Set to use insertion sort, rather than
1488 bubble sort.
1489
1490 * Added a check in Key_List::Output for the special case where
1491 the keys used are 1,$. It is possible to generate more
1492 efficient C code in this case.
