2002-10-14 Akim Demaille <akim@epita.fr>
Version 1.75.
2002-10-14 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (maintainer-check-posix): New.
2002-10-14 Akim Demaille <akim@epita.fr>
* data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
member.
2002-10-14 Akim Demaille <akim@epita.fr>
* src/tables.c (table_ninf_remap): base -> tab.
Reported by Matt Rosing.
2002-10-14 Paul Eggert <eggert@twinsun.com>
* tests/action.at, tests/calc.at, tests/conflicts.at,
tests/cxx-type.at, tests/headers.at, tests/input.at,
tests/regression.at, tests/synclines.at, tests/torture.at:
Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
so that the tests still work even if POSIXLY_CORRECT is set.
* doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
* data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
for portability to K&R hosts. Fix typo: signed char is guaranteed
only to 127, not to 128.
* data/glr.c (yysigned_char): New type.
* data/yacc.c (yysigned_char): Likewise.
* tests/regression.at (Web2c Actions): signed char -> yysigned_char.
2002-10-13 Paul Eggert <eggert@twinsun.com>
* data/yacc.c (yyparse): Rewrite to avoid "comparison is always
true due to limited range of data type" warning from GCC.
* data/c.m4 (b4_token_defines): Protect against double-inclusion
by wrapping enum yytokentype's definition inside #ifndef
YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
2002-10-13 Akim Demaille <akim@epita.fr>
* data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
Un yy- yyrhs to avoid the name clash with the global YYRHS.
2002-10-13 Akim Demaille <akim@epita.fr>
* Makefile.maint: Update from Autoconf 2.54.
* m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
2002-10-13 Akim Demaille <akim@epita.fr>
* src/print.c (print_state): Separate the list of solved conflicts
from the other items.
* tests/conflicts.at (Resolved SR Conflicts): Adjust.
2002-10-13 Akim Demaille <akim@epita.fr>
Let nondeterministic skeletons be usable with deterministic
tables.
With the patch, GAWK compiled by GCC without -O2 passes its test
suite using a GLR parser driven by LALR tables. It fails with -O2
because `struct stat' gives two different answers on my machine:
88 (definition of an auto var) and later 96 (memset on this var).
Hence the stack is badly corrumpted. The headers inclusion is to
blame: if I move the awk.h inclusion before GLR's system header
inclusion, the two struct stat have the same size.
* src/tables.c (pack_table): Always create conflict_table.
(token_actions): Always create conflict_list.
* data/glr.c (YYFLAG): Remove, unused.
2002-10-13 Akim Demaille <akim@epita.fr>
* configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
(O0FLAGS): New.
(VALGRIND, GXX): New.
* tests/atlocal.in (CFLAGS): Use O0FLAGS.
* tests/bison.in: Run $PREBISON a pre-command.
* tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
(maintainer-check-g++): New.
* Makefile.am (maintainer-check): New.
2002-10-13 Akim Demaille <akim@epita.fr>
* data/glr.c: Formatting changes.
Tweak some trace messages to match yacc.c's.
2002-10-13 Akim Demaille <akim@epita.fr>
GLR parsers sometimes raise parse errors instead of performing the
default reduction.
Reported by Charles-Henry de Boysson.
* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
check the length of the traces when %glr.
(_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
GLR's traces.
(AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
Test GLR parsers.
* data/glr.c (YYLEFTMOST_STATE): Fix its value.
(yyltype): Remove the yy prefix from the member names.
(yytable): Complete its comment.
(yygetLRActions): Map error action number from YYTABLE from
YYTABLE_NINF to 0.
(yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
(which was a bug: it should have been YYTABEL_NINF, and yet it was
not satisfying as we could compare an YYACTION computed from
YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
only value for error actions.
(yyreportParseError): In verbose parse error messages, don't issue
`error' in the list of expected tokens.
* data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
next action to perform to match glr.c's decoding.
(yytable): Complete its comment.
2002-10-13 Paul Eggert <eggert@twinsun.com>
Fix problem reported by Henrik Grubbstroem in
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
"nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
because the Bison parser reads the second action before reducing
the first one.
* src/scan-gram.l (rule_length): New static var.
Use it to keep track of the rule length in the scanner, since
we can't expect the parser to be in lock-step sync with the scanner.
(handle_action_dollar, handle_action_at): Use this var.
* tests/actions.at (Exotic Dollars): Test for the problem.
2002-10-12 Paul Eggert <eggert@twinsun.com>
* lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
* m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
Include <sys/time.h> when checking for clock_t and struct tms.
Use same include order as source.
This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
* lib/timevar.c: Update copyright date and clarify comments.
(get_time) [IN_GCC]: Keep the GCC version for reference.
* lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
GCC version as of today, then merge Bison's changes.
Change "GCC" to "Bison" in copyright notice. timevar.def's
author is Akim, so change that too.
* src/reader.c (grammar_current_rule_check):
Don't worry about the default action if $$ is untyped.
Prevents bogus warnings reported by Jim Gifford in
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
* data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
* data/glr.c, data/lalr1.cc, data/yacc.c:
Output token definitions before the first part of user declarations.
Fixes compatibility problem reported by Jim Gifford for kbd in
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
2002-10-11 Paul Eggert <eggert@twinsun.com>
* data/yacc.c (yyreport_parse_error): Remove, putting its body into...
(yyparse): here. This undoes some of the 2002-07-25 change.
Compatibility problem reported by Ralf S. Engelschall with
OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
2002-10-11 Akim Demaille <akim@epita.fr>
* tests/regression.at Characters Escapes): New.
* src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
characters.
Reported by Jan Nieuwenhuizen.
2002-10-11 Akim Demaille <akim@epita.fr>
* po/id.po: New.
2002-10-10 Paul Eggert <eggert@twinsun.com>
Portability fixes for bitsets; this also avoids several GCC
warnings.
* lib/abitset.c: Include <stddef.h>, for offsetof.
* lib/lbitset.c: Likewise.
* lib/abitset.c (abitset_bytes): Return a size that is aligned
properly for vectors of objects. Do not assume that adding a
header size to a multiple of a word size yields a value that is
properly aligned for the whole union.
* lib/bitsetv.c (bitsetv_alloc): Likewise.
* lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
unique names for structures.
* lib/ebitset.c (ebitset_bytes): Likewise.
* lib/lbitset.c (lbitset_bytes): Likewise.
* lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
abitset_or_and_cmp, abitset_copy): Supply prototype decls,
to improve the type-checking that GCC can do.
* lib/bitset.c (bitset_op4_cmp): Likewise.
* lib/bitset_stats.c (bitset_stats_count,
bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
bitset_stats_copy, bitset_stats_disjoint_p,
bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
bitset_stats_and_or_cmp, bitset_stats_andn_or,
bitset_stats_andn_or_cmp, bitset_stats_or_and,
bitset_stats_or_and_cmp): Likewise.
* lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
* lib/abitset.h: Include bitset.h, not bbitset.h.
* lib/ebitset.h: Likewise.
* lib/lbitset.h: Likewise.
* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
All instances of parameters of type enum bitset_opts are now of
type enum_bitset_opts, to conform to the C Standard, and similarly
for enum_bitset_type.
* lib/ebitset.c (enum_ebitset_find_mode): Likewise.
* lib/lbitset.c (enum_lbitset_find_mode): Likewise.
Do not use "struct bitset_struct" to mean different things in
different modules. Not only is this confusing, it violates
the C Standard, which requires that structure types in different
modules must be compatible if one is to be passed to the other.
* lib/bbitset.h (bitset): Now points to a union, not to a struct.
All instances of "struct bitset_struct *" replaced with "bitset".
* lib/bitset.h (struct bitset_struct): Remove, replacing with....
(union bitset_union, struct abitset_struct, struct ebitset_struct,
struct lbitset_struct, struct bitset_stats_struct): New types.
All uses of struct bitset_struct changed to union bitset_union,
etc.
* lib/abitset.c (struct abitset_struct, abitset,
struct bitset_struct): Remove.
* lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
struct bitset_struct): Remove.
* lib/ebitset.c (struct ebitset_struct, ebitset, struct
bitset_struct): Remove.
* lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
Likewise.
Do not call a function of type T using a call that assumes the
function is of a different type U. Standard C requires that a
function must be called with a type that is compatible with its
definition.
* lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
New decls.
* lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
New functions.
* lib/ebitset.c (PFV): Remove.
* lib/lbitset.c (PFV): Likewise.
* lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
decls.
(ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
(ebitset_vtable): Use them.
* lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
lbitset_xor): New functions.
(lbitset_vtable): Use them.
* lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
Declare.
* lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
GCC warning.
* lib/lbitset.c (LBITSET_CURRENT1): Likewise.
Use offsetof, for simplicity.
2002-10-06 Paul Eggert <eggert@twinsun.com>
* lib/bitset.h (bitset_reset): Do not assume that bitset_word is
the same width as int. This reapplies a hunk of the 2002-08-12 patch
<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
which was inadvertently undone by the 2002-09-30 patch.
* lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
the same width as int.
