Paul Eggert 570fe42828 New file, from gnulib. 2002-12-02 18:19:30 +00:00
Paul Eggert 6c30d6413e (no_cr_read, extend_location): Move to epilogue, 
and put only a forward declaration in the prologue.  This is for
consistency with the other scanner helper functions.
 2002-12-01 02:37:56 +00:00
Paul Eggert 6ba5559289 Type clashes now generate warnings, not errors, since it 
appears that POSIX may allow some grammars with type clashes.
 2002-11-30 09:52:42 +00:00
Paul Eggert e927351156 (grammar_current_rule_check): Warn about 
type clashes instead of complaining.
 2002-11-30 09:52:11 +00:00
Paul Eggert 38e71ff8c8 (Type Clashes): Expect warnings, not complaints. 2002-11-30 09:51:50 +00:00
Paul Eggert 3b0ee3aa8b fund -> found 2002-11-30 09:25:06 +00:00
Paul Eggert 6e746484fc Add Yacc Library. 
gram_error is static.
yylex and yyerror must be declared.
 2002-11-30 09:20:52 +00:00
Paul Eggert 74724a70a5 Describe Yacc library, lex-param and parse-param changes. 2002-11-30 09:18:34 +00:00
Paul Eggert 1fec91df90 (gram_error): Now static. Add static decl. 
(print_token_value): Omit parameter names from forward decl,
for consistency.
 2002-11-30 09:16:54 +00:00
Paul Eggert d18f45311a (gram_error): Remove decl. 2002-11-30 09:16:32 +00:00
Paul Eggert 93dd49ab29 (Yacc Library): New node. Regenerate top menu. 2002-11-30 09:11:30 +00:00
Paul Eggert 1f14d97ae5 (lib_LIBRARIES, liby_a_SOURCES): New macros. 2002-11-30 09:10:55 +00:00
Paul Eggert 0af19cd0c1 lib/main.c, lib/yyerror.c: New files. 2002-11-30 09:10:20 +00:00
Paul Eggert 38a92d500a Emphasize that yylex and yyerror must be declared before being used. 
E.g., one should typically declare them in the prologue.  Use GNU
coding style in examples.  Put "const" consistently after the type it
modifies.  Mention that C99 supports "inline".  Mention that yyerror
traditionally returns "int".
 2002-11-30 07:42:37 +00:00
Paul Eggert 6b0d38ab2c [a-f] -> [abcdef], so that we don't assume the C locale. 2002-11-29 09:03:16 +00:00
Paul Eggert 88510f9c07 %parse-param and %lex-param now take just one argument, the 
declaration; the argument name is deduced from the declaration.
 2002-11-29 08:45:33 +00:00
Paul Eggert da90e18c6e (Simple LALR Calculator): Adopt new convention for %parse-param 
and %lex-param.
 2002-11-29 08:45:14 +00:00
Paul Eggert 763ed7a687 "," now elicits a warning, rather than being 
a token; this is more compatible with byacc.

Paul Eggert 1773ceee65 (add_param): New function. 
(COMMA): Remove.

 2002-11-29 08:44:04 +00:00
Paul Eggert feeb0edaf1 (Parser Function, Pure Calling, Error Reporting, Table of Symbols): 
%parse-param and %lex-param now take just one argument, the
declaration; the argument name is deduced from the declaration.
 2002-11-29 08:43:12 +00:00

Paul Eggert ad8a3efc5a (print_token_value): Renamed from yyprint. 
All uses changed.
(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
The name "yycontrol" violates the name space rules, and this stuff
wasn't being used anyway.
(input): Remove action; this stuff wasn't being used.
(gram_error): Rename local variable yylloc -> loc.
 2002-11-27 18:33:18 +00:00

Paul Eggert dda7aa54b6 Sync with gnulib. 2002-11-25 07:50:25 +00:00
Paul Eggert 16f37b35a5 (Actions after errors): Use an output format 
more similar to that of the Printers and Destructors test.
Test the position of the ';' token too.
(Printers and Destructors): Likewise.
(Printers and Destructors: %glr-parser): Remove for now, to avoid
unnecessarily alarming people when the test fails.
 2002-11-25 07:36:54 +00:00
Paul Eggert 300a796626 (yyerrlab1): Move this label down, so that the 
parser does not discard the lookahead token if the user code
invokes YYERROR.  This change is required for POSIX conformance.
 2002-11-25 06:42:10 +00:00
Paul Eggert f6cf0f6e5f Sync with gnulib. 2002-11-23 07:25:41 +00:00

Paul Eggert 580043087e * lib/argmatch.c, lib/argmatch.h: Sync with gnulib. 
Avoid use of <assert.h>, as the GNU Coding Standards hint that one
should use `if (! x) abort ();' rather than `assert (x);', and
anyway it's one less thing to worry about configuring.

`yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
This fixes the regression with Sun ONE Studio 7 cc that I reported in
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.
 2002-11-19 09:33:21 +00:00

 2002-11-18 07:52:13 +00:00
Paul Eggert ee16363fd2 (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do not define to 
{}, since this breaks the common use of `YYDPRINTF ((...));' if a
single statement is desired (e.g. before `else').  Work around GCC
warnings by surrounding corresponding calls with {} if needed.
(yyhasResolvedValue): Remove unused function.
(yymergeOptionSets, yyresolvStack): Use `continue;' for empty
loop body.
(yyreportSyntaxError): Renamed from yyreportParseError.

"parse error" -> "syntax error" for POSIX compatibility.
"parsing stack overflow..." -> "parser stack overflow" so
that code matches Bison documentation.
 2002-11-15 20:32:21 +00:00
Paul Eggert edbc04c709 (AT_TEST_CPP_GUARD_H): Compile with -I., as Forte 7 C requires it, 
and it shouldn't hurt on other compilers.
 2002-11-15 01:57:23 +00:00
Paul Eggert 7ec1b48eb8 * src/output.c (output_skeleton): Call xfopen instead of

Paul Eggert 8fcc7db138 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that 
"$CC -E foo.h" is allowed, as this doesn't work with the Portland
Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
file twice in the grammar, as an extra check.

* tests/input.at (Torturing the Scanner): Surround the
backslash-newline tests with "#if 0", to make it less likely that
we'll run into compiler bugs.  Bring back solitary \ inside
comment, but add a closing comment to work around HP C bug.  Don't
test backslash-newline in C character constant.  This should fix
the input.at bug reported by Nelson H. F. Beebe in
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
 2002-11-14 23:08:27 +00:00

Paul Eggert 2b42986e75 (export YYLTYPE): Don't invoke "cc a.c b.c -o c"; the HP-UX 11i C 
compiler chatters during compilation.  Instead, invoke "cc -c a.c -o
a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
 2002-11-14 00:36:03 +00:00

Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
 2002-11-14 00:35:27 +00:00
Paul Eggert 149365be01 (Torturing the Scanner): Remove lines containing 
solitary backslashes, as they tickle a bug in the HP-UX 11i C
compiler.
 2002-11-14 00:26:45 +00:00
Paul Eggert 9a86cdb99b * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //

 2002-11-14 00:04:57 +00:00
Paul Eggert c240826c06 (Badly Collapsed GLR States): Avoid //

 2002-11-13 07:46:19 +00:00
Paul Eggert dbba6a3be7 [! BITSET_INLINE]: Remove.

to avoid shadowing warnings by GCC.
 2002-11-13 07:02:51 +00:00
Paul Eggert e84e65da40 (BITSET_INLINE): Remove. 2002-11-13 07:02:13 +00:00
Paul Eggert 53b7799056 (inline): Remove #define. It's the user's responsibility to #define 
it away, just like 'const'.  This fixes one of the bugs reported by
Nelson H.F. Beebe in
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>.
 2002-11-13 06:48:18 +00:00

Paul Eggert 322c501d89 Remove src/parse-gram.c, src/scan-gram.c, 
src/system.h.  Add src/parsegram.y, src/scan-gram.l.
 2002-11-13 06:40:06 +00:00
Paul Eggert 8a1dd2fe05 (po-check): Scan .l and .y files instead 
of the .c and the .h files that they generate.  Look for N_
as well as for _.  Try to avoid matching #define for N_ and _.
 2002-11-13 06:39:26 +00:00
Paul Eggert 0eae1c91c8 (struniq_new): Do not declare the return type 
to be 'const'; this violates the C standard.
 2002-11-13 06:27:18 +00:00
Paul Eggert ccdb39e0a6 Add src/system.h; this isn't really needed, but it keeps "make update" 
happy.
 2002-11-12 07:51:44 +00:00
Paul Eggert 62ddaef6a7 Regenerate. 2002-11-12 07:44:22 +00:00
Paul Eggert ea44c25efc No need to keep this file in CVS, since it's automatically generated. 2002-11-12 07:40:11 +00:00
Paul Eggert 7672019c42 Revamp to fix many (but not all) of the C- and M4-related quoting 
problems.  Among other things, this fixes the Bison bug reported
by Jan Hubicka when processing the Bash grammar.
 2002-11-12 07:33:36 +00:00
Paul Eggert 5b7f88c7f2 (Torturing the Scanner): Add tests that @oline@, 
__oline__, #output, $@, and @{ do not have unintended meanings.
 2002-11-12 07:28:25 +00:00
Paul Eggert e9683cfd3d (yylineno, yyoutname): Remove static vars, replacing 
them with auto vars.
Switch to new escape scheme, where @ is the escape character uniformly.
Abort if a stray escape character is found.  Avoid unbounded input
buffer when parsing non-escaped text.
 2002-11-12 07:27:51 +00:00
Paul Eggert ac060e78a3 (<SC_CHARACTER>): Don't worry about any backslash 
escapes other than \\ and \'; this simplifies the code.
(<SC_STRING>): Likewise, for \\ and \".
(<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
Use new escapes @{ and @} for [ and ].
 2002-11-12 07:27:04 +00:00
