-Sat Nov 11 13:43:17 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
+Sat May 2 12:31:51 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * src/version.cc (version_string): Remove the "(C++ version)" suffix.
+ It's redundant: the early C versions of gperf are called cperf.
+ Reported by Karl Berry.
+ * src/option.cc (Options::operator()): Trim the output of "gperf -v".
+
+Thu Apr 16 13:22:16 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * lib/Makefile.in, src/Makefile.in: Don't use $(TARGET_ARCH).
+ Solaris "make" sets it to a value not understood by "cc".
+
+Wed Apr 15 23:52:14 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * lib/Makefile.in, src/Makefile.in: Don't use implicit rules. Don't
+ use $<. AIX "make" and OSF/1 "make" have problems with both.
+ * src/gen-perf.cc, src/key-list.cc: Cast free() argument to char*,
+ otherwise it doesn't compile on SunOS 4.
+ * src/key-list.h: Declare structs outside of other declarations,
+ needed for OSF/1 cxx 5.5.
+ * lib/getopt.h: Use prototypes if __STDC__ || __cplusplus.
+ Don't give a prototype for getopt(), to avoid error on SunOS 4.
+ * lib/getopt.c: Declare strncmp, to avoid warnings.
+
+Tue Apr 14 23:24:07 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * lib/GetOpt.{h,cc}: Remove files.
+ * lib/getopt.{h,c}, lib/getopt1.c: New files, from GNU libc.
+ * lib/configure.in (AC_INIT): Search for hash.cc, not GetOpt.cc.
+ * lib/Makefile.in (OBJECTS): Remove GetOpt.o, add getopt.o, getopt1.o.
+ (getopt.o, getopt1.o, hash.o): Use explicit building rules. Some
+ "make"s don't support to have both implicit rules for "%.o : %.c"
+ and "%.o : %.cc" in the same Makefile.
+ * lib/hash.{h,cc}: Remove #pragma; there are no templates here.
+ * src/option.h (Options::usage): Remove.
+ (Options::short_usage, Options::long_usage): Declare.
+ * src/option.cc (Options::usage): Remove.
+ (Options::short_usage, Options::long_usage): New functions.
+ (long_options): New array.
+ (Options::operator()): Use getopt_long instead of GetOpt::operator(),
+ change all references to GetOpt members.
+
+ * src/std-err.{h,cc}: Remove files.
+ * src/gen-perf.cc, src/key-list.cc, list-node.cc, new.cc, options.cc:
+ Call fprintf(stderr) instead of Std_Err::report_error().
+ * src/key-list.h, src/list-node.h, src/options.h: Don't use class
+ Std_Err any more.
+ * src/option.cc (program_name): New variable.
+ * src/Makefile.in: Remove STD_ERR_H.
+ (OBJECTS): Remove std-err.o.
+
+Mon Mar 23 01:03:35 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * aclocal.m4, {lib,src,tests}/configure.in: Remove CL_CC_WORKS and
+ CL_CXX_WORKS, already contained in autoconf 2.12.
+
+ * src/gen-perf.cc, src/key-list.cc: Move some code from
+ Gen_Perf::Gen_Perf() to Key_List::output().
+ * src/Makefile.in: Update dependencies.
+
+ * src/options.{h,cc}: Remove option "-p".
+ * src/key-list.cc (Key_List::set_output_types): Rewrite.
+ (default_array_type, default_return_type): Remove.
+ * src/key-list.cc: Adjust "const" handling.
+ + With option "-t" [TYPE], don't emit wrong code if there is no
+ space before the struct's opening brace.
+
+Sun Mar 22 16:59:15 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * src/key-list.{h,cc}: Completely reorganized the output routines.
+ Rewrote from scratch the output_switch() function. Use classes
+ (Output_Constants, Output_Expr, Output_Compare) for abstraction.
+ In particular:
+ + Don't emit trailing whitespace and spurious blank lines.
+ + Adjust indentation of the arrays.
+ + Don't emit commas at the end of array initializers and
+ struct initializers.
+ + With option "-l" [LENTABLE], compare the length before
+ fetching the word from memory.
+ + With option "-S" [SWITCH], emit the comparison code just once,
+ not once in every switch statement.
+ + With option "-S" [SWITCH], choose the right switch statement
+ through a binary search, not a linear search.
+ + With option "-S" [SWITCH], emit straightforward comparisons
+ instead of switch statements with just one "case" label.
+ + With options "-S -p -t" [SWITCH, POINTER, TYPE], don't emit
+ spurious empty elements at the beginning of the wordlist array.
+ + With option "-D" [DUP] and not option "-S" [SWITCH], if there
+ is no more room for duplicate entries in the lookup array,
+ don't call `assert (i != 0)'. Instead, make the array larger :-)
+ + With option "-D" [DUP], if there are no duplicates, don't
+ automatically fall back to the non-"-D" algorithm. If the user
+ wants the non-"-D" algorithm, he can just not specify "-D".
+ + With option "-D" [DUP] and either options "-p -t" [POINTER, TYPE]
+ or not option "-S" [SWITCH], don't emit spurious empty elements
+ at the beginning of the wordlist array.
+ + With option "-D" [DUP], simplify the detection and processing
+ of duplicate entries in the lookup array.
+ + With options "-D -l" [DUP, LENTABLE] and not option "-S" [SWITCH],
+ don't forget to emit the lengthtable array.
+ + With options "-D -l -S" [DUP, LENTABLE, SWITCH], don't forget to
+ compare the lengths before comparing the strings.
+
+ * src/gen-perf.cc: No need to include <assert.h>.
+ * src/options.cc: Likewise.
+
+ * src/options.cc: Don't use `errno' after freopen failed.
+ * src/std-err.cc: `report_error' doesn't call strerror(errno) any
+ more. No need to include <string.h> and <errno.h>.
+
+ * tests/Makefile.in (check-*): Any difference between .exp and .out
+ is a failure. Don't ignore whitespace differences.
+
+ * tests/Makefile.in (check-lang-syntax): Add some more checks.
+
+Fri Mar 20 00:54:54 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * tests/jscript.gperf: Renamed from tests/javascript.gperf, because
+ of Minix and SVR2 14-character filename limit.
+ * src/key-list.cc (output_string): New function.
+ (Key_List::output_switch, Key_List::output_keyword_table): Call it.
+
+ * src/options.{h,icc,cc} (get_wordlist_name): New function. Add
+ option -W.
+ * src/key-list.cc (Key_List::output_switch,
+ Key_List::output_keyword_table, Key_List::output_lookup_function):
+ Use it.
+ Patch from William Bader <wbader@CSEE.Lehigh.Edu>.
+
+ * src/version.cc: Bump version number directly from 2.5 to 2.7,
+ because Schmidt's last release from 1991 carries version number 2.6.
+
+Tue Jul 30 00:02:39 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
+
+ * Fixed a small bug in the Key_List::output_keyword_table routine
+ that caused an extra newline to be printed if there where no
+ leading blank entries... (who cares, right?!)
+
+Mon Jul 29 22:05:40 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
+
+ * Modified the handling of the -E (emit enums rather than
+ #defines) option in conjunction with the -G option. Now, if -G
+ and -E are given the enums are generated outside the lookup
+ function, rather than within it!
+
+Mon Apr 8 18:17:04 1991 Doug Schmidt (schmidt at net4.ics.uci.edu)
+
+ * Yucko, there was a bug in the handling of -c (and of course the
+ new -I command in key-list.cc). Apparently when I added the
+ super-duper hack that provided support for duplicate keys I
+ forgot to update the strcmp output...
+
+Mon Mar 9 02:19:04 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
+
+ * Moved the documentation to doc/, put the stuff borrowed from
+ libg++ into lib/.

+ * src/bool-array.{h,cc}: Change type of `Bool_Array::size' from int
+ to unsigned int.
+ * src/bool-array.{h,cc}: Change type of `Bool_Array::init' argument
+ from STORAGE_TYPE to unsigned int.
+ * src/gen-perf.{h,cc}: Change two `Gen_Perf::compute_disjoint_union'

+ * src/iterator.cc: Cast to `unsigned char' before calling `isdigit'.
+ * src/key-list.{h,cc}: Change type of `Key_List::array_type',
+ `Key_List::return_type', `Key_List::struct_tag',

+ and return type of `Key_List::get_array_type',
+ `Key_List::get_special_input', `Key_List::save_include_src' from
+ `char *' to `const char *'.
+ * src/key-list.cc: Change "pretty gross" assignment.

+ * lib/GetOpt.cc: Likewise.
+ * src/key-list.cc (merge): Use iteration instead of recursion.
+ * src/list-node.{h,cc}: Change type of `List_Node::key',

+ * src/read-line.icc (get_line): Use iteration instead of tail recursion.
+ Don't call ungetc(EOF,stdin).
+ * src/std-err.{h,cc}: Change type of `Std_Err::program_name' and of
+ argument `Std_Err::report_error' from `char *' to `const char *'.
+ * src/std-err.cc: `report_error' doesn't call `exit' any more. All
+ callers changed to do that themselves.
+ * src/trace.h: Make constructor/destructor calls non-inline.
+
+ * src/key-list.cc (output_hash_function): If option[CPLUSPLUS],
+ always make the hash function inline.
+ (output): Declare the hash function inline, with the right name.
+ * src/options.{h,cc}, src/gen-perf.cc, src/key-list.cc: Remove
+ options -g, making it on by default. Remove option -a. Instead,
+ introduce "-L KR-C", "-L C", "-L ANSI-C", "-L C++".

+ * tests/jstest*.gperf, tests/validate: New tests.
+
+Sat Jan 31 01:38:11 1998 Alexandre Oliva <oliva@dcc.unicamp.br>

+
+Mon Apr 30 17:37:24 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Fixed stupid bug in Key_List::output_lookup_array that was
+ making the generated lookup[] array contain `chars' even
+ when the values stored in the chars are greater than 127!
+
+ * Changed the behavior of the -G (global table) option so that it
+ will output the `length[]' array in the global scope along with
+ the `word_list[]' array.
+
+ * Fixed a stupid bug in Key_List::output_lookup_function that
+ would always output the complicated `duplicate-handling' lookup
+ logic, even when there were no duplicates in the input!
+
+ * Yikes, had to modify a bunch of stuff in key-list.cc to correctly
+ handle duplicate entries. Changed the generated code so that
+ the MIN_HASH_VALUE is no longer subtracted off when calculating
+ the hash value for a keyword. This required changing some other
+ code by substituting MAX_HASH_VALUE for TOTAL_KEYS in several places.
+ Finally, this means that the generated tables may contain leading
+ null entries, but I suppose it is better to trade-off space to get
+ faster performance...
+
+Mon Mar 26 13:08:43 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Updated version number to 2.4 to reflect the latest changes.
+
+ * Changed the main program so that it always prints out gperf's
+ execution timings to the generated output file.
+
+Sun Mar 25 12:39:30 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Added the -Z option so that users can specify the name of the
+ generated class explicitly. Updated documentation to reflect
+ this change.
+
+ * Modified the generated C++ class interface so that the functions
+ are declared static (to remove the overhead of passing the `this'
+ pointer). This means that operator()() can no longer be used,
+ since it only works on non-static member functions.
+ Also changed things so that there is no constructor (why waste
+ the extra call, when it doesn't do anything, eh?)
+
+ * Modified the behavior of Key_List::output when the -L C++ option
+ is enabled. Previously the code generated use const data members
+ to record MIN_WORD_LENGTH, MIN_HASH_VALUE, etc. However, as
+ pointed out by James Clark this may result in suboptimal behavior
+ on the part of C++ compilers that can't inline these values.
+ Therefore, the new behavior is identical to what happens with
+ -L C, i.e., either #defines or function-specific enums are used.
+ Why sacrifice speed for some abstract notion of `code purity?' ;-)
+
+Tue Mar 6 18:17:42 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Added the -E option that defines constant values using an enum
+ local to the lookup function rather than with #defines. This
+ also means that different lookup functions can reside in the
+ same file. Thanks to James Clark (jjc@ai.mit.edu).
+
+Sat Mar 3 20:19:00 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
+
+ * Added a special case to key_list::output_switch that doesn't
+ generate extra comparisons when the `-S' is given an argument
+ of 1 (the normal case). This should speed up the generated
+ code output a tad...

+
+Wed Feb 14 23:27:24 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
+

+ gperf replaced each '%' with the succeeding character.
+
+ * Added support for multiple target language generation. Currently
+ handled languages are C and C++, with C as the default. Updated
+ documentation and option handler to reflect the changes.
+
+ * Added a global destructor to new.cc and removed the #ifdef, since
+ the bloody thing now works with libg++.
+
+Mon Feb 14 13:00:00 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)

+ USENIX C++ Conference in San Francisco. Yow!

+
+ * #ifdef'd out the new.cc memory allocator, since there are
+ problems with this and the libg++ stuff.
+
+ * Changed key-list.h so that class Vectors is a public (rather
+ than private) base class for class Key_List. The previous
+ form was illegal C++, but wasn't being caught by the old
+ g++ compiler. Should work now... ;-)
+
+Sun Dec 10 14:08:23 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
+
+ * Added several changes from rfg@ics.uci.edu. These changes
+ help to automate the build process.
+
+Wed Nov 15 15:49:33 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
+
+ * Removed conditional compilation for GATHER_STATISTICS. There's
+ really no good reason to avoid collecting this info at run-time,
+ since that section of code is *hardly* the bottleneck... ;-)
+
+ * Simplified the C output routines in Key_List::set_output_types
+ and Key_List::output_keyword_table a bit in order to
+ speed-up and clean up the code generation.
+
+ * Modified function Key_List::get_special_input so that it does
+ not try to `delete' a buffer that turned out to be too short.
+ This is important since the new memory management scheme
+ does not handle deletions. However, adding a small amount of
+ garbage won't hurt anything, since we generally don't do this
+ operation more than a couple times *at most*!
+
+ * Created a new file (new.cc) which includes my own overloaded
+ operator new. This function should dramatically reduce the
+ number of calls to malloc since it grabs large chunks and
+ doles them out in small pieces. As a result of this change
+ the class-specific `operator new' was removed from class List_Node.
+
+Tue Nov 14 21:45:30 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
+
+ * Continued to refine the great hack. The latest trick is to
+ try and replace most uses of dynamic memory (i.e., calls to
+ new) with uses of gcc dynamic arrays (i.e., an alloca solution).
+ This makes life much easier for the overall process-size, since
+ it reduces the amount of overhead for memory management. As a
+ side-effect from this change there is no reason to have the
+ Bool_Array::dispose member function, so it's outta here!
+
+ * Fixed a stupid bug that was an disaster waiting to happen...
+ Instead of making the boolean array large enough to index
+ max_hash_value it was only large enough to index max_hash_value
+ - 1. Once again, an off-by-one mistake in C/C++!!!!
+
+Mon Nov 13 19:38:27 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
+
+ * Added the final great hack! This allows us to generate hash tables
+ for near-perfect hash functions that contain duplicates, *without*
+ having to use switch statements! Since many compilers die on large
+ switch statements this feature is essential. Furthermore, it appears
+ that the generated code is often *smaller* than that put out by
+ compilers, even though a large, sparse array must be created.
+ Here's the general idea:
+
+ a. Generate the wordlist as a contiguous block of keywords,
+ just as before when using a switch statement. This
+ wordlist *must* be sorted by hash value.
+
+ b. Generate the lookup array, which is an array of signed
+ {chars,shorts,ints}, (which ever allows full coverage of
+ the wordlist dimensions). If the value v, where v =
+ lookup[hash(str,len)], is >= 0 and < TOTAL_KEYWORDS, then we
+ simply use this result as a direct access into the wordlist
+ array to snag the keyword for comparison.
+
+ c. Otherwise, if v is < -TOTAL_KEYWORDS or > TOTAL_KEYWORDS
+ this is an indication that we'll need to search through
+ some number of duplicates hash values. Using a hash
+ linking scheme we'd then index into a different part of
+ the hash table that provides the starting index and total
+ length of the duplicate entries to find via linear search!
+
+Sun Nov 12 13:48:10 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
+
+ * Simplified Key_List::output_min_max considerably by recognizing
+ that since the keyword list was already sorted by hash value finding
+ the min and max values is trivial!
+
+ * Improved the debugging diagnostics considerably in classes Key_List,
+ Hash_Table, and Gen_Perf.
+
+ * Modified the `-s' option so that a negative argument is now
+ interpreted to mean `allow the maximum associated value to be
+ about x times *smaller* than the number of input keys.' This
+ should help prevent massive explosion of generated hash table
+ size for large keysets.
+
+Sat Nov 11 11:31:13 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
+
+ * Added a field in class Key_List that counts the total number
+ of duplicate keywords, both static and dynamic.
+
+ * Added a new member function Bool_Array that deletes the dynamic
+ memory allocated to Bool_Array::storage_array. This space may
+ be needed for subsequent options, so it made sense to free it as
+ soon as possible...
+
+ * Renamed file/class Alpha_Vectors to Vectors, to avoid problems
+ with 14 character length filenames on SYSV. Also changed file
+ adapredefined.gperf to adadefs.gperf in the ./tests directory.
+
+ * Modified class Options by changing the member function
+ Options::total_positions to Options::get_charset_size and
+ Options::set_charset_size. These two routines now either return
the total charset size *or* the length of the largest keyword
if the user specifies the -k'*' (ALLCHARS) option. This change
cleans up client code.

+Tue Jan 10 00:08:16 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Added a new option, -n, that instructs gperf to not use the
+ length of an identifier when computing the hash functions.
+ I'm not sure how useful this is!
+
+ * Retransmitted the distribution to rocky.oswego.edu. Hopefully,
+ this will work!
+
+ * Began fixing the indentation and capitalization to conform
+ to the GNU coding guidelines.
+
+Mon Jan 9 22:23:18 1989 Doug Schmidt (schmidt at pompe.ics.uci.edu)
+
+ * Fixed horrible bug in Read_Line::Readln_Aux. This was
+ a subtle and pernicous off-by-1 error, that overwrote
+ past the last character of the input string buffer. I
+ think this fault was killing the vax!
+
+ * Yow, fixed an oversight in List_Node::List_Node, where the
+ pointer field Next was uninitialized. Luckily, the new routine
+ seems to return 0 filled objects the first time through!
+
+Sun Jan 8 13:43:14 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Modified the ``key linked'' diagnostic in Key_List::Read_Keys
+ to be more helpful and easy to read.
+
+ * Fixed the List_Node::List_Node so that it would ignore trailing
+ fields if the -t option was not enabled.
+
+ * Moved the List_Node declarations out of keylist.h and
+ into a file of its own, called listnode.cc and listnode.h
+ Made Set_Sort a member function of class List_Node.
+
+ * Massively updated the documentation in the gperf.texinfo file.
+
+ * Polished off the major revision to the print functions,
+ added a few new tests in the Makefile to check for the
+ validity of the program and ftp'ed the entire distribution
+ off to Doug Lea for libg++. ( changed it to
+ 1.3 to reflect the major changes with the generated
+ C code ).
+
+ * Fixed Key_List::Print_Switch to deal with the -p and -t options.
+ This meant that the ``still-born'' function Key_List::
+ Print_Type_Switch was superflous, so I removed it.
+ Also, removed the restriction in Option that the -p and
+ -t options couldn't be used simultaneously.
+
+ * Modified List_Node::List_Node, to perform only 1 call to
+ ``new'' when dynamically allocating memory for the Key_Set
+ and the Uniq_Set.
+
+Sat Jan 7 14:10:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
+
+ * Fixed a big bug with the new policy of nesting the
+ wordlist inside of generated function ``in_word_set.''
+ I'd forgotten to declare the wordlist array as static!
+ ( arrgh ).
+
+ * Added a new function Key_List::Set_Types, that figures out
+ the return type for generated function ``in_word_set,''
+ the user-defined ``struct tag,'' if one is used, and also
+ formates the array type for the static local array.
+
+ * Changed the print routines to take advantage of the
+ new -p option.
+
+ * Began adding the hooks to allow the return of a pointer
+ to a user defined struct location from the generated
+ ``in_word_set'' function instead of the current 0 or 1
+ return value. Created function Key_List::Print_Type_Switch
+ and added option -p to class Option, allowing the user to
+ request generation of the aforementioned pointers returned
+ instead of booleans.
+
+ * Put in checks in class Option to make sure that -S and -t
+ options are not used simultaneously. This restriction
+ will be removed in subsequent releases, once I decide on
+ a clean way to implement it.
+
+ * Sent version 1.2 to Doug Lea for possible inclusion into
+ the libg++ distribution.
+
+ * Moved the static word_list array inside the generated function
+ in_word_set. This supports better data hiding.
+
+ * Added a texinfo file, gperf.texinfo
+
+ * Revised the Makefile to cleanup the droppings from texinfo
+ and changed the name of gperf.cc and gperf.h to perfect.cc
+ and perfect.h.
+
+Fri Jan 6 13:04:45 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
+
+ * Implemented the switch statement output format. Much better
+ for large datasets in terms of space used.
+
+ * Added new functions to break up the Key_List::Output function.
+ Functions added were Key_List::Print_Switch, Key_List::Print_Min_Max,
+ Key_List::Print_Keyword_Table, Key_List::Print_Hash_Function,
+ and Key_List::Print_Lookup_Function. This simplifies the
+ big mess in Key_List::Output considerably!
+
+ * Added switch statement option to Options, which potentially
+ trades time for space in the generated lookup code.
+
+Thu Jan 5 22:46:34 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
+
+ * Released version 1.1
+
+ * Fixed a bug with Gperf::Merge_Set, it was skipping letters shared
+ between the Set_1 and Set_2.
+
+ * Added the optimal min/max algorithm in Key_List::Output. This
+ runs in O ( 3n/2 ), rather than O ( 2n ) time.
+
+ * Changed Gperf::Sort_Set to use insertion sort, rather than
+ bubble sort.
+
+ * Added a check in Key_List::Output for the special case where
+ the keys used are 1,$. It is possible to generate more
+ efficient C code in this case.

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+
+* gperf is now a stand-alone package, untied from libg++.
+* Autoconfiguring.
+* Removed the "-a" and "-g" options, extended the "-L" option instead.

+gperf \- generate a perfect hash function from a key set
+.SH SYNOPSIS
+.B gperf
+[
+.B \-adghijklnoprsStv
+] [
+.I keyfile
+]
+.SH DESCRIPTION
+
+\fIgperf\fP reads a set of ``keys'' from \fIkeyfile\fP (or, by
+default, from the standard input) and attempts to find a non-minimal
+perfect hashing function that recognizes a member of the key set in
+constant, i.e., O(1), time. If such a function is found the program
+generates a pair of \fIC\fP source code routines that perform the
+hashing and table lookup. All generated code is directed to the
+standard output.
+
+Please refer to the \fIgperf.texi\fP file for more information.
+This file is distributed with \fIgperf\fP release.

+@unnumberedsec Preamble
+
+ The license agreements of most software companies try to keep users
+at the mercy of those companies. By contrast, our General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users. The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, that you receive source code or can get it if you want it,
+that you can change the software or use pieces of it in new free
+programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of a such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must tell them their rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.

+@center TERMS AND CONDITIONS
+@end ifinfo
+
+@enumerate
+@item
+This License Agreement applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License. The
+``Program'', below, refers to any such program or work, and a ``work based
+on the Program'' means either the Program or any work containing the
+Program or a portion of it, either verbatim or with modifications. Each
+licensee is addressed as ``you''.
+
+@item
+You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program. You may charge a fee for the physical act of
+transferring a copy.
+
+@item
+You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+@itemize @bullet
+@item
+cause the modified files to carry prominent notices stating that
+you changed the files and the date of any change; and
+
+@item
+cause the whole of any work that you distribute or publish, that
+in whole or in part contains the Program or any part thereof, either
+with or without modifications, to be licensed at no charge to all
+third parties under the terms of this General Public License (except
+that you may choose to grant warranty protection to some or all
+third parties, at your option).
+
+@item
+If the modified program normally reads commands interactively when
+run, you must cause it, when started running for such interactive use
+in the simplest and most usual way, to print or display an
+announcement including an appropriate copyright notice and a notice
+that there is no warranty (or else, saying that you provide a
+warranty) and that users may redistribute the program under these
+conditions, and telling the user how to view a copy of this General
+Public License.
+
+@item
+You may charge a fee for the physical act of transferring a
+copy, and you may at your option offer warranty protection in
+exchange for a fee.
+@end itemize
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+@item
+You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 1 and 2 above provided that you also do one of the following:
+
+@itemize @bullet
+@item
+accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of
+Paragraphs 1 and 2 above; or,
+
+@item
+accompany it with a written offer, valid for at least three
+years, to give any third party free (except for a nominal charge
+for the cost of distribution) a complete machine-readable copy of the
+corresponding source code, to be distributed under the terms of
+Paragraphs 1 and 2 above; or,
+
+@item
+accompany it with the information you received as to where the
+corresponding source code may be obtained. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form alone.)
+@end itemize
+
+Source code for a work means the preferred form of the work for making
+modifications to it. For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+@item
+You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License. However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+@item
+By copying, distributing or modifying the Program (or any work based
+on the Program) you indicate your acceptance of this license to do so,
+and all its terms and conditions.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these
+terms and conditions. You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of the license which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.

+@unnumberedsec Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to humanity, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+ To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+``copyright'' line and a pointer to where the full notice is found.

+The GNU @code{gperf} perfect hash function generator utility was
+originally written in GNU C++ by Douglas C. Schmidt. It is now also
+available in a highly-portable ``old-style'' C version. The general
+idea for the perfect hash function generator was inspired by Keith
+Bostic's algorithm written in C, and distributed to net.sources around
+1984. The current program is a heavily modified, enhanced, and extended
+implementation of Keith's basic idea, created at the University of
+California, Irvine. Bugs, patches, and suggestions should be reported
+to @code{<bug-gnu-utils@@gnu.org>} and @code{<schmidt@@ics.uci.edu>}.

+Special thanks is extended to Michael Tiemann and Doug Lea, for

+@end itemize

+@node Motivation, Search Structures, Contributors, Top
+@chapter Introduction
+
+@code{gperf} is a perfect hash function generator written in C++. It
+transforms an @var{n} element user-specified keyword set @var{W} into
+a perfect hash function @var{F}. @var{F} uniquely maps keywords in
+@var{W} onto the range 0..@var{k}, where @var{k >= n}. If
+@var{k = n} then @var{F} is a @emph{minimal} perfect hash function.
+@code{gperf} generates a 0..@var{k} element static lookup table and a
+pair of C functions. These functions determine whether a given
+character string @var{s} occurs in @var{W}, using at most one probe
+into the lookup table.
+
+@code{gperf} currently generates the reserved keyword recognizer for
+lexical analyzers in several production and research compilers and
+language processing tools, including GNU C, GNU C++, GNU Pascal, GNU
+Modula 3, and GNU indent. Complete C++ source code for @code{gperf} is
+available via anonymous ftp from @code{ics.uci.edu} and
+@code{ftp.santafe.edu}. @code{gperf} was also distributed along with
+the GNU libg++ library for several years. A highly portable,
+functionally equivalent K&R C version of @code{gperf} is archived in
+comp.sources.unix, volume 20. Finally, a paper describing
+@code{gperf}'s design and implementation in greater detail is available
+in the Second USENIX C++ Conference proceedings.
+
+@node Search Structures, Description, Motivation, Top
+@chapter Static search structures and GNU @code{gperf}
+
+A @dfn{static search structure} is an Abstract Data Type with certain
+fundamental operations, e.g., @emph{initialize}, @emph{insert},
+and @emph{retrieve}. Conceptually, all insertions occur before any
+retrievals. In practice, @code{gperf} generates a @code{static} array
+containing search set keywords and any associated attributes specified
+by the user. Thus, there is essentially no execution-time cost for the
+insertions. It is a useful data structure for representing @emph{static
+search sets}. Static search sets occur frequently in software system
+applications. Typical static search sets include compiler reserved
+words, assembler instruction opcodes, and built-in shell interpreter
+commands. Search set members, called @dfn{keywords}, are inserted into
+the structure only once, usually during program initialization, and are
+not generally modified at run-time.
+
+Numerous static search structure implementations exist, e.g.,
+arrays, linked lists, binary search trees, digital search tries, and
+hash tables. Different approaches offer trade-offs between space
+utilization and search time efficiency. For example, an @var{n} element
+sorted array is space efficient, though the average-case time
+complexity for retrieval operations using binary search is
+proportional to log @var{n}. Conversely, hash table implementations
+often locate a table entry in constant time, but typically impose
+additional memory overhead and exhibit poor worst case performance.
+
+
+@emph{Minimal perfect hash functions} provide an optimal solution for a
+particular class of static search sets. A minimal perfect hash
+function is defined by two properties:
+
+@itemize @bullet
+@item
+It allows keyword recognition in a static search set using at most
+@emph{one} probe into the hash table. This represents the ``perfect''
+property.
+@item
+The actual memory allocated to store the keywords is precisely large
+enough for the keyword set, and @emph{no larger}. This is the
+``minimal'' property.
+@end itemize
+
+For most applications it is far easier to generate @emph{perfect} hash
+functions than @emph{minimal perfect} hash functions. Moreover,
+non-minimal perfect hash functions frequently execute faster than
+minimal ones in practice. This phenomena occurs since searching a
+sparse keyword table increases the probability of locating a ``null''
+entry, thereby reducing string comparisons. @code{gperf}'s default
+behavior generates @emph{near-minimal} perfect hash functions for
+keyword sets. However, @code{gperf} provides many options that permit
+user control over the degree of minimality and perfection.
+
+Static search sets often exhibit relative stability over time. For
+example, Ada's 63 reserved words have remained constant for nearly a
+decade. It is therefore frequently worthwhile to expend concerted
+effort building an optimal search structure @emph{once}, if it
+subsequently receives heavy use multiple times. @code{gperf} removes
+the drudgery associated with constructing time- and space-efficient
+search structures by hand. It has proven a useful and practical tool
+for serious programming projects. Output from @code{gperf} is currently
+used in several production and research compilers, including GNU C, GNU
+C++, GNU Pascal, and GNU Modula 3. The latter two compilers are not yet
+part of the official GNU distribution. Each compiler utilizes
+@code{gperf} to automatically generate static search structures that
+efficiently identify their respective reserved keywords.

+@end menu
+
+The perfect hash function generator @code{gperf} reads a set of
+``keywords'' from a @dfn{keyfile} (or from the standard input by
+default). It attempts to derive a perfect hashing function that
+recognizes a member of the @dfn{static keyword set} with at most a
+single probe into the lookup table. If @code{gperf} succeeds in
+generating such a function it produces a pair of C source code routines
+that perform hashing and table lookup recognition. All generated C code
+is directed to the standard output. Command-line options described
+below allow you to modify the input and output format to @code{gperf}.
+
+By default, @code{gperf} attempts to produce time-efficient code, with
+less emphasis on efficient space utilization. However, several options
+exist that permit trading-off execution time for storage space and vice
+versa. In particular, expanding the generated table size produces a
+sparse search structure, generally yielding faster searches.
+Conversely, you can direct @code{gperf} to utilize a C @code{switch}
+statement scheme that minimizes data space storage size. Furthermore,
+using a C @code{switch} may actually speed up the keyword retrieval time
+somewhat. Actual results depend on your C compiler, of course.
+
+In general, @code{gperf} assigns values to the characters it is using
+for hashing until some set of values gives each keyword a unique value.
+A helpful heuristic is that the larger the hash value range, the easier
+it is for @code{gperf} to find and generate a perfect hash function.
+Experimentation is the key to getting the most from @code{gperf}.
+
+@node Input Format, Output Format, Description, Description
+@section Input Format to @code{gperf}
+
+You can control the input keyfile format by varying certain command-line
+arguments, in particular the @samp{-t} option. The input's appearance
+is similar to GNU utilities @code{flex} and @code{bison} (or UNIX
+utilities @code{lex} and @code{yacc}). Here's an outline of the general
+format:
+
+@example
+@group
+declarations
+%%
+keywords
+%%
+functions
+@end group
+@end example
+
+@emph{Unlike} @code{flex} or @code{bison}, all sections of @code{gperf}'s input
+are optional. The following sections describe the input format for each
+section.
+

+* Declarations:: @code{struct} Declarations and C Code Inclusion.
+* Keywords:: Format for Keyword Entries.
+* Functions:: Including Additional C Functions.

+@node Declarations, Keywords, Input Format, Input Format
+@subsection @code{struct} Declarations and C Code Inclusion
+
+The keyword input file optionally contains a section for including
+arbitrary C declarations and definitions, as well as provisions for
+providing a user-supplied @code{struct}. If the @samp{-t} option
+@emph{is} enabled, you @emph{must} provide a C @code{struct} as the last
+component in the declaration section from the keyfile file. The first
+field in this struct must be a @code{char *} identifier called @samp{name},
+although it is possible to modify this field's name with the @samp{-K}
+option described below.
+
+Here is simple example, using months of the year and their attributes as
+input:
+
+@example
+@group
+struct months @{ char *name; int number; int days; int leap_days; @};
+%%
+january, 1, 31, 31
+february, 2, 28, 29
+march, 3, 31, 31
+april, 4, 30, 30
+may, 5, 31, 31
+june, 6, 30, 30
+july, 7, 31, 31
+august, 8, 31, 31
+september, 9, 30, 30
+october, 10, 31, 31
+november, 11, 30, 30
+december, 12, 31, 31
+@end group
+@end example
+
+Separating the @code{struct} declaration from the list of key words and
+other fields are a pair of consecutive percent signs, @code{%%},
+appearing left justified in the first column, as in the UNIX utility
+@code{lex}.
+
+Using a syntax similar to GNU utilities @code{flex} and @code{bison}, it
+is possible to directly include C source text and comments verbatim into
+the generated output file. This is accomplished by enclosing the region
+inside left-justified surrounding @code{%@{}, @code{%@}} pairs. Here is
+an input fragment based on the previous example that illustrates this
+feature:
+
+@example
+@group
+%@{
+#include <assert.h>
+/* This section of code is inserted directly into the output. */
+int return_month_days (struct months *months, int is_leap_year);
+%@}
+struct months @{ char *name; int number; int days; int leap_days; @};
+%%
+january, 1, 31, 31
+february, 2, 28, 29
+march, 3, 31, 31
+...
+@end group
+@end example
+
+It is possible to omit the declaration section entirely. In this case
+the keyfile begins directly with the first keyword line, e.g.:
+
+@example
+@group
+january, 1, 31, 31
+february, 2, 28, 29
+march, 3, 31, 31
+april, 4, 30, 30
+...
+@end group
+@end example
+
+@node Keywords, Functions, Declarations, Input Format
+@subsection Format for Keyword Entries
+
+The second keyfile format section contains lines of keywords and any
+associated attributes you might supply. A line beginning with @samp{#}
+in the first column is considered a comment. Everything following the
+@samp{#} is ignored, up to and including the following newline.
+
+The first field of each non-comment line is always the key itself. It
+should be given as a simple name, i.e., without surrounding
+string quotation marks, and be left-justified flush against the first
+column. In this context, a ``field'' is considered to extend up to, but
+not include, the first blank, comma, or newline. Here is a simple
+example taken from a partial list of C reserved words:
+
+@example
+@group
+# These are a few C reserved words, see the c.@code{gperf} file
+# for a complete list of ANSI C reserved words.
+unsigned
+sizeof
+switch
+signed
+if
+default
+for
+while
+return
+@end group
+@end example
+
+Note that unlike @code{flex} or @code{bison} the first @code{%%} marker
+may be elided if the declaration section is empty.
+
+Additional fields may optionally follow the leading keyword. Fields
+should be separated by commas, and terminate at the end of line. What
+these fields mean is entirely up to you; they are used to initialize the
+elements of the user-defined @code{struct} provided by you in the
+declaration section. If the @samp{-t} option is @emph{not} enabled
+these fields are simply ignored. All previous examples except the last
+one contain keyword attributes.

+@node Functions, , Keywords, Input Format
+@subsection Including Additional C Functions
+
+The optional third section also corresponds closely with conventions
+found in @code{flex} and @code{bison}. All text in this section,
+starting at the final @code{%%} and extending to the end of the input
+file, is included verbatim into the generated output file. Naturally,
+it is your responsibility to ensure that the code contained in this
+section is valid C.

+@section Output Format for Generated C Code with @code{gperf}
+
+Several options control how the generated C code appears on the standard
+output. Two C function are generated. They are called @code{hash} and
+@code{in_word_set}, although you may modify the name for
+@code{in_word_set} with a command-line option. Both functions require
+two arguments, a string, @code{char *} @var{str}, and a length
+parameter, @code{int} @var{len}. Their default function prototypes are
+as follows:
+
+@example
+@group
+static int hash (char *str, int len);
+int in_word_set (char *str, int len);
+@end group
+@end example
+
+By default, the generated @code{hash} function returns an integer value
+created by adding @var{len} to several user-specified @var{str} key
+positions indexed into an @dfn{associated values} table stored in a
+local static array. The associated values table is constructed
+internally by @code{gperf} and later output as a static local C array called
+@var{hash_table}; its meaning and properties are described below.
+@xref{Implementation}. The relevant key positions are specified via the
+@samp{-k} option when running @code{gperf}, as detailed in the @emph{Options}
+section below. @xref{Options}.
+
+Two options, @samp{-g} (assume you are compiling with GNU C and its
+@code{inline} feature) and @samp{-a} (assume ANSI C-style function
+prototypes), alter the content of both the generated @code{hash} and
+@code{in_word_set} routines. However, function @code{in_word_set} may
+be modified more extensively, in response to your option settings. The
+options that affect the @code{in_word_set} structure are:
+
+@itemize @bullet
+@table @samp
+@item -t
+Make use of the user-defined @code{struct}.
+
+@item -S @var{total switch statements}
+Generate 1 or more C @code{switch} statement rather than use a large,
+(and potentially sparse) static array. Although the exact time and
+space savings of this approach vary according to your C compiler's
+degree of optimization, this method often results in smaller and faster
+code.
+@end table
+@end itemize
+
+If the @samp{-t} and @samp{-S} options are omitted, the
+default action is to generate a @code{char *} array containing the keys,
+together with additional null strings used for padding the array. By
+experimenting with the various input and output options, and timing the
+resulting C code, you can determine the best option choices for
+different keyword set characteristics.

+
+@item -7
+This option specifies that all strings that will be passed as arguments

+solely consist of 7-bit ASCII characters (characters in the range 0..127).
+(Note that the ANSI C functions @code{isalnum} and @code{isgraph} do

+8-bit characters.
+
+@item -c
+Generates C code that uses the @code{strncmp} function to perform
+string comparisons. The default action is to use @code{strcmp}.
+
+@item -C
+Makes the contents of all generated lookup tables constant, i.e.,
+``readonly''. Many compilers can generate more efficient code for this
+by putting the tables in readonly memory.
+
+@item -E
+Define constant values using an enum local to the lookup function rather

+
+@item -I

+Generate the static table of keywords as a static global variable,
+rather than hiding it inside of the lookup function (which is the
+default behavior).
+
+@item -W @var{hash table array name}
+Allows you to specify the name for the generated array containing the
+hash table. Default name is @samp{wordlist}. This option permits the
+use of two hash tables in the same file, even when the option @samp{-G}
+is given.
+
+@item -S @var{total switch statements}
+Causes the generated C code to use a @code{switch} statement scheme,
+rather than an array lookup table. This can lead to a reduction in both
+time and space requirements for some keyfiles. The argument to this
+option determines how many @code{switch} statements are generated. A
+value of 1 generates 1 @code{switch} containing all the elements, a
+value of 2 generates 2 tables with 1/2 the elements in each

+
+@itemize @bullet
+@table @samp
+@item -k @var{keys}
+Allows selection of the character key positions used in the keywords'
+hash function. The allowable choices range between 1-126, inclusive.
+The positions are separated by commas, e.g., @samp{-k 9,4,13,14};
+ranges may be used, e.g., @samp{-k 2-7}; and positions may occur
+in any order. Furthermore, the meta-character '*' causes the generated
+hash function to consider @strong{all} character positions in each key,
+whereas '$' instructs the hash function to use the ``final character''
+of a key (this is the only way to use a character position greater than
+126, incidentally).
+
+For instance, the option @samp{-k 1,2,4,6-10,'$'} generates a hash
+function that considers positions 1,2,4,6,7,8,9,10, plus the last
+character in each key (which may differ for each key, obviously). Keys
+with length less than the indicated key positions work properly, since
+selected key positions exceeding the key length are simply not
+referenced in the hash function.
+
+@item -l
+Compare key lengths before trying a string comparison. This might cut
+down on the number of string comparisons made during the lookup, since
+keys with different lengths are never compared via @code{strcmp}.
+However, using @samp{-l} might greatly increase the size of the
+generated C code if the lookup table range is large (which implies that
+the switch option @samp{-S} is not enabled), since the length table
+contains as many elements as there are entries in the lookup table.
+
+@item -D
+Handle keywords whose key position sets hash to duplicate values.
+Duplicate hash values occur for two reasons:
+
+@itemize @bullet
+@item
+Since @code{gperf} does not backtrack it is possible for it to process
+all your input keywords without finding a unique mapping for each word.
+However, frequently only a very small number of duplicates occur, and
+the majority of keys still require one probe into the table.
+@item
+Sometimes a set of keys may have the same names, but possess different
+attributes. With the -D option @code{gperf} treats all these keys as part of
+an equivalence class and generates a perfect hash function with multiple
+comparisons for duplicate keys. It is up to you to completely
+disambiguate the keywords by modifying the generated C code. However,
+@code{gperf} helps you out by organizing the output.
+@end itemize
+
+Option @samp{-D} is extremely useful for certain large or highly
+redundant keyword sets, e.g., assembler instruction opcodes.
+Using this option usually means that the generated hash function is no
+longer perfect. On the other hand, it permits @code{gperf} to work on
+keyword sets that it otherwise could not handle.
+
+@item -f @var{iteration amount}
+Generate the perfect hash function ``fast''. This decreases @code{gperf}'s
+running time at the cost of minimizing generated table-size. The
+iteration amount represents the number of times to iterate when
+resolving a collision. `0' means iterate by the number of keywords.
+This option is probably most useful when used in conjunction with options
+@samp{-D} and/or @samp{-S} for @emph{large} keyword sets.
+
+@item -i @var{initial value}
+Provides an initial @var{value} for the associate values array. Default
+is 0. Increasing the initial value helps inflate the final table size,
+possibly leading to more time efficient keyword lookups. Note that this
+option is not particularly useful when @samp{-S} is used. Also,
+@samp{-i} is overriden when the @samp{-r} option is used.
+
+@item -j @var{jump value}
+Affects the ``jump value'', i.e., how far to advance the
+associated character value upon collisions. @var{Jump value} is rounded
+up to an odd number, the default is 5. If the @var{jump value} is 0
+@code{gperf} jumps by random amounts.
+
+@item -n
+Instructs the generator not to include the length of a keyword when
+computing its hash value. This may save a few assembly instructions in
+the generated lookup table.
+
+@item -o
+Reorders the keywords by sorting the keywords so that frequently
+occuring key position set components appear first. A second reordering
+pass follows so that keys with ``already determined values'' are placed
+towards the front of the keylist. This may decrease the time required
+to generate a perfect hash function for many keyword sets, and also
+produce more minimal perfect hash functions. The reason for this is
+that the reordering helps prune the search time by handling inevitable
+collisions early in the search process. On the other hand, if the
+number of keywords is @emph{very} large using @samp{-o} may
+@emph{increase} @code{gperf}'s execution time, since collisions will begin
+earlier and continue throughout the remainder of keyword processing.
+See Cichelli's paper from the January 1980 Communications of the ACM for
+details.
+
+@item -r
+Utilizes randomness to initialize the associated values table. This
+frequently generates solutions faster than using deterministic
+initialization (which starts all associated values at 0). Furthermore,
+using the randomization option generally increases the size of the
+table. If @code{gperf} has difficultly with a certain keyword set try using
+@samp{-r} or @samp{-D}.
+
+@item -s @var{size-multiple}
+Affects the size of the generated hash table. The numeric argument for
+this option indicates ``how many times larger or smaller'' the maximum
+associated value range should be, in relationship to the number of keys.
+If the @var{size-multiple} is negative the maximum associated value is
+calculated by @emph{dividing} it into the total number of keys. For
+example, a value of 3 means ``allow the maximum associated value to be
+about 3 times larger than the number of input keys''.
+
+Conversely, a value of -3 means ``allow the maximum associated value to
+be about 3 times smaller than the number of input keys''. Negative
+values are useful for limiting the overall size of the generated hash
+table, though this usually increases the number of duplicate hash
+values.
+
+If `generate switch' option @samp{-S} is @emph{not} enabled, the maximum
+associated value influences the static array table size, and a larger
+table should decrease the time required for an unsuccessful search, at
+the expense of extra table space.
+
+The default value is 1, thus the default maximum associated value about
+the same size as the number of keys (for efficiency, the maximum
+associated value is always rounded up to a power of 2). The actual
+table size may vary somewhat, since this technique is essentially a
+heuristic. In particular, setting this value too high slows down
+@code{gperf}'s runtime, since it must search through a much larger range
+of values. Judicious use of the @samp{-f} option helps alleviate this
+overhead, however.

+@chapter Known Bugs and Limitations with @code{gperf}
+
+The following are some limitations with the current release of
+@code{gperf}:
+
+@itemize @bullet
+@item
+The @code{gperf} utility is tuned to execute quickly, and works quickly
+for small to medium size data sets (around 1000 keywords). It is
+extremely useful for maintaining perfect hash functions for compiler
+keyword sets. Several recent enhancements now enable @code{gperf} to
+work efficiently on much larger keyword sets (over 15,000 keywords).
+When processing large keyword sets it helps greatly to have over 8 megs
+of RAM.
+
+However, since @code{gperf} does not backtrack no guaranteed solution
+occurs on every run. On the other hand, it is usually easy to obtain a
+solution by varying the option parameters. In particular, try the
+@samp{-r} option, and also try changing the default arguments to the
+@samp{-s} and @samp{-j} options. To @emph{guarantee} a solution, use
+the @samp{-D} and @samp{-S} options, although the final results are not
+likely to be a @emph{perfect} hash function anymore! Finally, use the
+@samp{-f} option if you want @code{gperf} to generate the perfect hash
+function @emph{fast}, with less emphasis on making it minimal.
+
+@item
+The size of the generate static keyword array can get @emph{extremely}
+large if the input keyword file is large or if the keywords are quite
+similar. This tends to slow down the compilation of the generated C
+code, and @emph{greatly} inflates the object code size. If this
+situation occurs, consider using the @samp{-S} option to reduce data
+size, potentially increasing keyword recognition time a negligible
+amount. Since many C compilers cannot correctly generated code for
+large switch statements it is important to qualify the @var{-S} option
+with an appropriate numerical argument that controls the number of
+switch statements generated.
+
+@item
+The maximum number of key positions selected for a given key has an
+arbitrary limit of 126. This restriction should be removed, and if
+anyone considers this a problem write me and let me know so I can remove
+the constraint.

+
+@node Projects, Implementation, Bugs, Top
+@chapter Things Still Left to Do
+
+It should be ``relatively'' easy to replace the current perfect hash
+function algorithm with a more exhaustive approach; the perfect hash
+module is essential independent from other program modules. Additional
+worthwhile improvements include:
+
+@itemize @bullet
+@item
+Make the algorithm more robust. At present, the program halts with an
+error diagnostic if it can't find a direct solution and the @samp{-D}
+option is not enabled. A more comprehensive, albeit computationally
+expensive, approach would employ backtracking or enable alternative
+options and retry. It's not clear how helpful this would be, in
+general, since most search sets are rather small in practice.
+
+@item
+Another useful extension involves modifying the program to generate
+``minimal'' perfect hash functions (under certain circumstances, the
+current version can be rather extravagant in the generated table size).
+Again, this is mostly of theoretical interest, since a sparse table
+often produces faster lookups, and use of the @samp{-S} @code{switch}
+option can minimize the data size, at the expense of slightly longer
+lookups (note that the gcc compiler generally produces good code for
+@code{switch} statements, reducing the need for more complex schemes).
+
+@item
+In addition to improving the algorithm, it would also be useful to
+generate a C++ class or Ada package as the code output, in addition to
+the current C routines.

+
+A paper describing the high-level description of the data structures and
+algorithms used to implement @code{gperf} will soon be available. This
+paper is useful not only from a maintenance and enhancement perspective,
+but also because they demonstrate several clever and useful programming
+techniques, e.g., `Iteration Number' boolean arrays, double
+hashing, a ``safe'' and efficient method for reading arbitrarily long
+input from a file, and a provably optimal algorithm for simultaneously
+determining both the minimum and maximum elements in a list.

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */
