CHANGES
1
Version 4.6d
2
3
2000/8/10
4
- use newer versions of mkdirs.sh and install.sh
5
- regenerate configure script with autoconf 2.13
6
- restructure aclocal.m4
7
- modify Makefile.in to allow $(bindir) and $(mandir) to be altered
8
independently of $(prefix) and $(exec_prefix) (patch by Carsten Leonhardt
9
<leo@debian.org>).
10
11
Version 4.6c
12
13
2000/7/8
14
- add a clause to handle "__extension__" before extern declarations.
15
(report by Bob van der Poel <bvdpoel@uniserve.com>)
16
17
Version 4.6b
18
19
1999/12/27
20
- correct check for size of vec[] array in yaccExpected(), broken in 4.6a
21
changes.
22
(report by Wolfgang Wander)
23
1999/12/19
24
- add keywords "restrict", "_Bool", "_Complex", "_Imaginary" based on c9x
25
draft.
26
- add keywords "__restrict__" and "__restrict", for gcc.
27
(report by Wolfgang Wander <wwc@rentec.com>)
28
29
Version 4.6a
30
31
1999/12/14
32
- change vec[] array in yaccExpected() to be dynamically allocated. It was a
33
fixed-size (10 entries) array before. Also fix problem reported by Wolfgang
34
Wander <wwc@rentec.com>, which is that if the array were empty, it was passed
35
to qsort() with a zero-size, causing a core dump.
36
- add to syntax.c & corresponding test-cases the typedef/identifier example.
37
1999/10/21
38
- allow identifiers to be the same as typedef names, handle this case:
39
typedef int badStyle;
40
void badFunc(int *badStyle) { }
41
(reported by Paul Haas <paulh@iware.com>)
42
1999/1/3
43
- add '__extension__' keyword
44
45
Version 4.6
46
47
- Since cproto is no longer being distributed on USENET in shar file format,
48
the patchlev.h and MANIFEST files have been removed.
49
The patchlevel number has been removed from the version number.
50
51
- Moved files out of the porting directory into separate platform specific
52
directories. The emx directory has files used to compile using EMX.
53
The os2 directory has files used to compile on OS/2 using Watcom C/C++.
54
The win32 directory has files to compile on Windows 95 and Windows NT
55
using Watcom C/C++.
56
57
- correct order of include-path to keep standard include (e.g., /usr/include)
58
at the end of the search list.
59
60
- modified lint-library include-stack recovery to work on OSF/1.
61
62
- supply default initializer for lint-library const data
63
64
- corrected reset of __attribute__((noreturn))
65
66
- added '__volatile', '__const__', '__inline' keywords to grammar to
67
accommodate gcc.
68
69
- modified configure script to add several development/debugging options (i.e.,
70
--with-trace, --with-dbmalloc, --with-dmalloc).
71
72
- modified ifdefs to avoid using predefined 'unix' (not defined on AIX or CLIX)
73
74
Patchlevel 5 (April 1996)
75
76
- corrected instance of fclose on a file pointer after pclose was done (found
77
with Electric Fence).
78
79
- corrected script make_bat.sh to prevent expansion of \n in argument-string.
80
81
- Modified handling of lint library option to allow generation of lint libraries
82
for ANSI compilers (set -a -l).
83
84
- corrected a missing 'void' in parameter list
85
86
- modified to allow compile/test with 'dmalloc' library in addition to
87
'dbmalloc'.
88
89
- corrected memory leak in yyerror.c, and allocation-size for cpp command.
90
91
- added keywords to work with gcc 2.7.0
92
93
- corrected unresolved references to flush_varargs() when OPT_LINTLIBRARY
94
is not defined
95
96
Patchlevel 4 (August 1995)
97
98
- Added -S option to only output static declarations.
99
100
- Fix: The configure script didn't replace @CFLAGS@, @CPPFLAGS@ and @LDFLAGS@
101
in the makefile generated from makefile.in.
102
103
- Fix: The -a option generated incorrect function definitions.
104
105
- update test-cases for the -f2 fix in patch 3.
106
107
- remove dependency on GNU-make from makefile.in
108
109
- corrected configuration script that tests whether yyerror can be extended
110
(had cached wrong flag, preventing some configurations from being
111
recognized).
112
113
- added calls for 'flush_varargs()' to correct situation in lint-library output
114
where VARARGS comments were not reset properly when a function
115
was skipped.
116
117
- improved the logic of 'strip_name()' (used to compute include-directives for
118
the lint-library option) so that it recognizes the conventional include
119
directory created by a GCC install.
120
121
Patchlevel 3 (January 1995)
122
123
- check for a special case in lint-library generation, i.e., prototype
124
arguments of the form "*()", which need more parentheses for SunOS's lint.
125
126
- modified configure.in, aclocal.m4, makefile.in to work with autoconf 2.1
127
(also added install.sh - note that "install-sh" is not an MS-DOS-compatible
128
filename).
129
130
- derive the program name from the argv[0] entry, in case it's installed
131
under a different name.
132
133
- Fix: The -f2 option generated incorrect prototypes for functions that
134
take a variable argument list.
135
136
- use 'sed' rather than 'flip' to apply trailing CR's to MS-DOS scripts.
137
138
Patchlevel 2 (October 1994)
139
140
- modified grammar to recognize C++ ref-variables (i.e., '&' as a prefix to
141
identifiers at the top lexical level). Lint libraries are formatted without
142
this '&', since lint doesn't grok C++. This corrects an error in cproto 4.0
143
which caused '&' characters to be suppressed altogether, e.g., when filtering
144
with the "-t" option.
145
146
- modified rules that generate MANIFEST to put auto-generated scripts there
147
also, if they've been created (e.g., cd testing; make scripts).
148
149
- modified makefile.in to have shar target for both GNU shar and Rick Salz's
150
cshar utility.
151
152
- use 'const' in yyerror.c, otherwise the error-reporting auto-configuration
153
does not work.
154
155
- don't use "#elif" preprocessor control; not all systems support it.
156
157
Patchlevel 1 (October 1994)
158
159
- Added testing scripts for MS-DOS and VMS.
160
161
- Added makefile for Borland C++ for OS/2.
162
163
- Fix: When the -a, -t or -b options were used, '&' characters were stripped
164
from the output files.
165
166
- Fix: The system.h file should define EXIT_SUCCESS and EXIT_FAILURE
167
regardless of the presence of <stdlib.h>.
168
169
Patchlevel 0 (dickey, September 1994)
170
171
- corrected two malloc-defects in lint library generation (one place where
172
generated parameter name was copied rather than allocated, and another memory
173
leak).
174
175
- corrected generation of lint library function body, to handle function
176
pointers.
177
178
- changed the implicit lint library function type from "" to "void", to avoid
179
special-cases in the function-body generation.
180
181
- added logic using 'NestedParams' to suppress prototype-arguments in lint
182
library function-pointer arguments.
183
184
- corrected lint-library function parameter derived from prototype "char [2]"
185
(parameter name wasn't supplied).
186
187
- added PRINTFLIKE and SCANFLIKE to the comments interpreted for the lint
188
library translation.
189
190
- modified "LINT_PREPRO" comment to pass-thru all comment text if no count is
191
given.
192
193
- added new comment keyword "LINT_SHADOWED" to generate "#undef symbol" before
194
each function template in lint libraries (useful for processing files that
195
define both macros and functions with the same names).
196
197
- interpret GCC's __attribute__ noreturn and format for lint-library text
198
(GCC 2.5.8 preprocessor passes these macros through, GCC 2.6 apparently does
199
not).
200
201
- treat carriage-return (^M) as whitespace where appropriate.
202
203
- added configuration-test to avoid conflict with prototype for 'popen()'
204
205
- added several function-pointer regression test-cases
206
207
Version 3
208
209
Patchlevel 9 (dickey, August 1994)
210
211
- use 'autoconf' to make a UNIX configure-script.
212
213
- recognize GCC extensions '__inline' and '__attribute__'
214
215
- added ifdef OPT_LINTLIBRARY to allow compiling without the lint library
216
code (saves about 4kb).
217
218
- corrected some logic that made incorrect commenting for options -c -f1
219
(e.g., "void (*Sigdisp(int sig, void (*func)(int sig)))(int sig)").
220
221
- corrected logic that macroizes (e.g., with P_) functions like 'Sigdisp'
222
(it wasn't doing anything about the trailing "(int sig)").
223
224
- corrected handling of K&R conversion of mixed-mode functions (K&R style
225
with prototypes in arguments) to avoid losing comments.
226
227
- modified logic for options -c -f2 so that cproto inserts a space before
228
the beginning of a comment when it immediately follows an '*'.
229
230
- enhanced error reporting with new module yyerror.c which (attempts to)
231
report the expected token type/name when a syntax error is encountered.
232
233
- modified the grammar.y file to try to recover from errors at the next
234
semicolon (as well as the next right curly bracket).
235
236
- modified to process lex/yacc files with gcc as C-preprocessor.
237
238
- Added option "-O" to force redirection of errors without shell operations
239
(useful for VAX/VMS and MS-DOS in particular).
240
241
- added "\s" as a synonym for space in the format options (-P, -F, -C)
242
243
- tested on Solaris with lex/yacc and flex 2.4.6 / bison 1.22
244
(SunOS explorer 5.3 Generic_101318-42 sun4m sparc; gcc 2.6.0)
245
246
- tested on SunOS 4.1.1 with lex/yacc and flex 2.4.6 / bison 1.22
247
(SunOS calvin 4.1.1 1 sun4c)
248
249
- tested on IRIX with lex/yacc
250
(IRIX dbs3 5.2 02282015 IP19 mips)
251
252
- tested on Linux 0.99.15 with lex/yacc and flex 2.4.6 / bison 1.22 / byacc 1.9
253
254
- tested on MS-DOS with flex 2.37 / byacc 1.9 (built with turboc.mak).
255
(Bison uses too much stack space).
256
257
- tested on VAX/VMS 6.1 with VAX-C 3.2 and flex 2.4.6 / bison 1.22.
258
259
- moved non-UNIX files into 'porting' subdirectory.
260
261
- added 'testing' subdirectory, for simple regression tests.
262
263
- tested for memory leaks with dbmalloc (on Linux).
264
265
Patchlevel 8 (internal: dickey/cthuang, June 1993)
266
267
- added files 'lintlibs.c' and 'strkey.c'
268
269
- Allow dollar signs in identifiers
270
271
- Defined FAIL, SUCCESS to use in 'exit()' calls (VMS is approximately the
272
reverse of UNIX).
273
274
- Added option "-o" to force redirection without shell operations (useful for
275
VAX/VMS in particular).
276
277
- Added options "-l" (lintlibrary format), "-T" (typedefs), "-x" (externs
278
in include-files).
279
280
- Added "-C" option to cpp-invocation (to support VARARGS-decoding for -l
281
option).
282
283
- Modified grammar.y so that if -T option is turned on, instances of untagged
284
struct, union or enum are shown with the contents of the curly braces.
285
286
- Modified lex.l so that it sets 'return_val' iff at least one return statement
287
within curly braces returns an expression. Use this to support -l option.
288
289
- Modified semantic.c (for -l option) to put tabs after short names for better
290
readability. Also (only -l option), put a blank line before function
291
definitions and typedefs.
292
293
- Corrected lex.l so that it recognizes preprocessor lines within curly braces.
294
295
- Modified 'gen_prototype()' to trim 'extern' and 'auto' keywords from the text
296
(so that 'extern' is emitted in this function only if the -e option is
297
specified). Do this to support -l option (and to correct normal usage, which
298
implies that -e option is needed to put an 'extern' before declaration).
299
300
- Corrected test in 'put_decl_spec()' by using 'strkey()' (which tests for a
301
name, not simply a substring).
302
303
- Modified semantic.c to use 'put_string()' and related procedures to simplify
304
pretty-printing of lint-library text (mainly to control blank lines). (See
305
'fmt_library()').
306
307
- linted some xmalloc calls using ALLOC macro.
308
309
Patchlevel 7
310
311
- Fix: The processing of string literals is now more robust.
312
313
- Removed the -f4 option which generated prototypes like
314
315
int main P_((int argc, char **argv));
316
317
Use the -m option now to put a guard macro around the prototype
318
parameter list. Use the -m option together with -f3 (which is the
319
default) to produce the same output as the old -f4 option. The option
320
to set the guard macro name is now -M.
321
322
- Comments in prototype parameter lists are now disabled by default.
323
Use the -c option now to output these comments.
324
325
- Can now process #include directives in which the file is specified with
326
a #define macro.
327
328
- Now does not convert function definitions that take the formal
329
parameter va_alist from <varargs.h>.
330
331
- Now recognizes the GNU C modifiers __const and __inline__.
332
333
Patchlevel 6
334
335
- Fix: A function in lex.l exploited the ANSI C feature of concatenating
336
string literals. This prevented the module from being compiled with
337
pre-ANSI C compilers.
338
339
Patchlevel 5
340
341
- Fix: The -v option did not output declarations for function pointers.
342
343
- Fix: String literals continued over more than one line messed up the
344
line number count.
345
346
- Fix: The program generated incorrect prototypes for functions that
347
take a variable argument list using <varargs.h>.
348
349
- Fix: When converting functions from the standard input, cproto
350
generated no output if no functions needed to be converted.
351
352
- Fix: Now does not output a warning if an untagged struct is found in a
353
typedef declaration.
354
355
- Added the -b option which rewrites function definition heads to
356
include both old style and new style declarations separated by a
357
conditional compilation directive. For example, the program can
358
generate
359
360
#ifdef ANSI_FUNC
361
362
int
363
main (int argc, char *argv[])
364
#else
365
366
int
367
main (argc, argv)
368
int argc;
369
char *argv[]
370
#endif
371
{
372
}
373
374
Added the -B option to set the preprocessor directive that appears at
375
the beginning of such definitions.
376
377
- Added the keyword "interrupt" to the set of type qualifiers when
378
compiled on a UNIX system.
379
380
- The MS-DOS version now recognizes the type modifiers introduced by
381
Microsoft C/C++ 7.00.
382
383
- Now recognizes ANSI C trigraphs (yuck!).
384
385
- Now use "#if __STDC__" instead of "#if defined(__STDC__)".
386
387
- GNU bison orders the y.tab.c sections differently than yacc, which
388
resulted in references to variables before they were declared. The
389
grammar specification was modified to also be compatible with bison.
390
391
Patchlevel 4
392
393
- Fix: A typedef name defined as a pointer to char, short or float was
394
incorrectly promoted if it was used to specify a formal parameter.
395
For example, for the definition
396
397
typedef char *caddr_t;
398
399
int strlen (s)
400
caddr_t s;
401
{
402
}
403
404
cproto generated the incorrect prototype
405
406
int strlen(int s);
407
408
- Added implementation of the ANSI function tmpfile() for systems that
409
don't have it.
410
- If compiled with Microsoft C, cproto preprocesses its input by running
411
the command "cl /E". To eliminate the error messages when the file
412
<malloc.h> is included, the program now recognizes the specifier
413
_based(void).
414
415
Patchlevel 3
416
417
- Fix: The program didn't generate prototypes for functions defined with
418
the extern specifier.
419
- Fix: The -c option didn't output a space before parameter names in
420
generated prototypes.
421
- Added the -E option to specify a particular C preprocessor to run or
422
to stop the program from running the C preprocessor.
423
- Added the -q option to stop the program from outputting error messages
424
when it cannot read the file specified in an #include directive.
425
- Made the yacc specification compatible with UNIX SYSVR4 yacc.
426
427
Patchlevel 2
428
429
- Fix: The function definition conversion may produce a mangled function
430
definition if an #include directive appears before the function and
431
no comments appear between the directive and the function.
432
- Fix: The size of the buffer allocated for the C preprocessor command
433
string did not include enough space for options set in the environment
434
variable CPROTO.
435
- Replaced the -n option with -c which disables all comments in the
436
generated prototypes.
437
- Replaced the enum's with #define constants to accommodate C compilers
438
that don't like enumerators in constant expressions.
439
440
Patchlevel 1
441
442
- Fix: The program was calling ftell() on an invalid FILE pointer.
443
444
Patchlevel 0
445
446
- Added options to convert function definitions between the old style
447
and ANSI C style.
448
- Options can be specified from the environment variable CPROTO.
449
- The MS-DOS version recognizes more Microsoft C and Borland C++ type
450
modifiers (such as _cdecl, _far, _near).
451
- Fix: Formal parameters specified with typedef names were not promoted.
452
For example, for the definition
453
454
typedef unsigned short ushort;
455
456
void test (x)
457
ushort x;
458
{
459
}
460
461
cproto generated the incorrect prototype
462
463
void test(ushort x);
464
465
while the correct one is
466
467
void test(int x);
468
469
- Fix: Incorrect prototypes were generated for functions that returned
470
function pointers. For example, cproto generated an incorrect
471
prototype for the function definition
472
473
void (*signal(int x, void (*func)(int y)))(int z)
474
{
475
}
476
477
- Fix: Changed calls to memory allocation functions to abort the program
478
if they fail.
479
480
Version 2
481
482
Patchlevel 3
483
484
- Made cproto compatible with GNU flex.
485
- After compiling with the preprocessor symbol TURBO_CPP defined, on
486
MS-DOS systems, cproto will pipe its input through the Turbo C
487
preprocessor.
488
- Fix: Typedef names may now be omitted from typedef declarations.
489
For example, every C compiler I tried accepts
490
491
typedef int;
492
493
and some even give warnings when encountering this statement.
494
495
Patchlevel 2
496
497
- Cproto is now able to generate prototypes for functions defined in lex
498
and yacc source files named on the command line. Lex and yacc source
499
files are recognized by the .l or .y extension.
500
- Fix: The memory allocated to the typedef symbol table was not being
501
freed after scanning each source file.
502
- Fix: Failure to reset a variable during error recovery caused
503
segmentation faults.
504
505
Patchlevel 1
506
507
- Fix: Cproto incorrectly generated the parameter "int ..." in
508
prototypes of functions taking variable parameters.
509
- Fix: Function definitions can now be followed by an optional
510
semicolon. I found this feature in every C compiler I tried.
511
512
Patchlevel 0
513
514
- Added formal parameter promotion.
515
- Added prototype style that surrounds prototypes with a guard macro.
516
- Handles C++ style comment //.
517
- Nifty new way to set prototype output format.
518
- Got rid of the shell wrapper used to pipe the input through the C
519
preprocessor (cpp).
520
- For the port to MS-DOS, I modified cproto to run without cpp, but
521
since I didn't want to reimplement cpp, the program processes only the
522
#include and #define directives and ignores all others. Macro names
523
defined by the #define directive are treated like typedef names if
524
they appear in declaration specifiers.

Version 1

528
Patchlevel 3
529
530
- Fix: identical typedef names and struct tags should be allowed.
531
For example:
532
533
typedef struct egg_salad egg_salad;
534
535
struct egg_salad {
536
int mayo;
537
};
538
539
void dine(egg_salad l)
540
{
541
}
542
543
Patchlevel 2
544
545
- Fix: A typedef statement should allow a list of typedefs to be declared.
546
Example:
547
548
typedef int a, *b;
549
550
- Fix: When run with the -v option on this input, cproto did not output
551
a declaration for variable "b":
552
553
char *a="one"; char *b="two";
554
555
- The options were renamed. Added new options that change the output
556
format of the prototypes.
557
558
Patchlevel 1
559
560
- Fix: Incorrect prototypes were produced for functions that take
561
function pointer parameters or return a function pointer. For example,
562
cproto produced an erroneous prototype for this function definition:
563
564
void
565
(*signal (sig, func))()
566
int sig;
567
void (*func)();
568
{
569
/* stuff */
570
}
571
572
- The lexical analyser now uses LEX. It should still be compatible with
573
FLEX.
