bf60087f69 Add new information about how to unpack the bison source on
MSDOS and other systems which have 8.3 file name restrictions
using djunpack.bat and fnchange.lst.

90ddbd5eed Replace file name scan-gram-c.c with scangram-c.c and
scan-skel-c.c with /src/scanskel-c.c to conform with
the 8.3 file name restriction on MSDOS.

3e7a2cd95f * data/glr.c: Reorder typedef declarations for structs to match order
of struct declarations.
Rename yystack everywhere to yystackp except in yyparse where it's not
a pointer.
(yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
consistency.
(yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
(yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
(yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
lint.

6c65b1525f Work around flex portability bug. 2005-12-09 23:53:14 +00:00
Paul Eggert
2cec9080f6 Work around portability problem on Solaris 10: flex-generated
files include <stdio.h> before <config.h>, which messes up
because the latter defines __EXTENSIONS__.  Address the problem
by creating two new little files that include <config.h> first,
then include the flex-generated files.  Rewrite everyone else
to include <config.h> first, as well.
* lib/timevar.c: Always include "config.h".
* src/Makefile.am (bison_SOURCES): Replace scan-gram.l with
scan-gram-c.c, and scan-skel.l with scan-skel-c.c.
(EXTRA_bison_SOURCES): New macro.
* src/scan-gram-c.c, src/scan-skel-c.c: New files.
* src/system.h: Don't include config.h.

12ce2df60d Cleanups so that Bison-generated parsers have less lint.
* data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
Prepend /*ARGSUSED*/, for lint's sake.
* data/glr.c (YYUSE): Properly parenthesize, and use an alternate
definition if 'lint' is defined.
(YYID): New macro (or function, if lint).
All uses of /*CONSTCOND*/0 replaced by YYID(0).
* data/yacc.c: Likewise.
* data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
(yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
* data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
is C++ only.
* data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
* data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
Use YYID(0) rather than 0, for lint.
(yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
(yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

stacks, and iterate another stack in order to call user
destructors.
* tests/glr-regression.at (No users destructors if stack 0 deleted):
New test case.
(Duplicated user destructor for lookahead): This test now is expected
to succeed.

af3412cdea * data/yacc.c: Say "parser skeleton" rather than "file", since
it's no longer just a file.
* data/glr.c: Grant a special exception for C GLR parsers, that
reads like the already-existing exception for C LALR(1) parsers.
* data/glr.cc: Likewise.
* data/lalr1.cc: Likewise.
* data/location.cc: Likewise.

d9963c8597 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
Fix typos in previous change that broke 'make check'.
YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
supported in C.
* tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
Don't check NUM-STDERR-LINES, since the output format is fluctuating.
We can revert this once things settle down.

035aa4a0bb * src/conflicts.c (conflicts_print): Don't print file name twice

change.
