* src/getargs.c (AS_FILE_NAME): New.
(getargs): Use it to convert DOSish file names.
* src/files.c (base_name): Rename as full_base_name to avoid
clashes with `base_name ()'.
(get_extension_index): Remove.
(filename_split): New.
(compute_base_names): N-th rewrite, using filename_split.
* lib/xstrndup.c, lib/strchr.c:
New, stolen from the Fileutils 4.1.
* lib/Makefile.am (libbison_a_SOURCES): Adjust.
* configure.in: Check for the presence of memrchr, strchr,
strnlen, and of their prototypes.
Don't check for strndup: we no longer use it.
* src/system.h: Adjust the prototypes.
convention is to fetch on entry.
* tests/torture.at (GNU Cim Grammar): Reintroduce their weird
'switch' without a following semicolon.
* tests/regression.at (braces parsing): New.
* tests/calc.at (exp): We no longer need to special case GCC as
the warning flags are passed by configure.
* tests/atlocal.in: Adjust.
* configure.in: Bump to 1.30j.
The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it. It still does with fprintf.
Also, s/cstdio.h/cstdio/.
cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
Sparc, as they were causing more porting problems than the
(minor) performance improvement was worth.
otherwise, since we range over their symbols, we might look at a
nonterminal which no longer ``exists'', i.e., it is not counted in
`nvars', hence we overflow our arrays.
RHS's properly.
* tests/torture.at (GNU AWK Grammar): New.
* tests/sets.at (Nullable): New.
* src/nullable.c (set_nullable): Instead of blindly looping over
`ritems', loop over the rules, and then over their rhs's.
Work around Autotest bugs.
* src/warshall.c (bitmatrix_print): Don't use `+--+' as table
frame, because Autotest understand lines starting with a `+' as
traces from the shell. Then, they are not processed properly.
Admittedly an Autotest bug, but we don't have time to wait for
Autotest to catch up.
* tests/regression.at (Broken Closure): Adjust to the new table
frames.
Move to...
* tests/sets.at: here.
Reported by Pascal Bart.
* src/warshall.c (bitmatrix_print): New.
(TC): Use it.
When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
j must be the outer loop.
* tests/regression.at (Broken Closure): New.
removal of useless rules via CPP but via `if (0)', so that the
compiler still check the code is valid.
For instance, it should have noticed `rline' no longer exists: use
the `line' member of rule_t.
* src/gram.c (dummy, rline): Remove, unused.
items of a state, not only its kernel.
* src/print.c (print_core): If `trace_flag', then invoke closure
before outputting the items of the state (print_core is no longer
a correct name them).
(print_results): Invoke new_closure/free_closure if needed.
have a valid SHIFTS, which NSHIFTS is possibly 0.
* src/LR0.c (shifts_new): Be global and move to..
* src/state.c, src/state.h: here.
* src/conflicts, src/lalr.c, src/output.c, src/print.c,
* src/print_graph: Adjust.
argument, as it is replaced by the results by the unique caller.
(build_relations): Merely invoke transpose: it handles the memory
deallocation.
Improve variable locality.
Avoid variables used as mere abbreviations.
(compute_lookaheads): Use arrays instead of pointers.
`destroyed'), we now sometimes examine them, and store information
related to them. Hence we need to know their number, and adjust
memory allocations.
* src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
static.
* src/LR0.c (allocate_itemsets): The memory allocated to
`symbol_count' was used for two different purpose: once to count
the number of occurrences of each symbol, and later reassigned to
`shift_symbol', containing the symbol that can be shifted from a
given state.
Deobfuscate, i.e., allocate, use and free `symbol_count' here
only, and...
(new_itemsets): Allocate `shift_symbol' here.
(allocate_itemsets): symbol_count includes useless nonterminals.
Make room for them.
(free_storage): Use `free', not `XFREE', for pointers that cannot
be null.
* src/gram.c (dummy): Remove, now there is actual code in gram.c.
(This useless function was defined only to work around VMS linkers
that can't handle compilation units with variables only).
* src/reduce.c (dump_grammar): Use it to trace the construction of
ritem.
(CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
Gettext doesn't compile cleanly, and dies with -Werror.
* src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
Include WARNING_CFLAGS here.
* lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
before being defined.
First arg is int, not unsigned.
* lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
(SIZE_MAX, UINT_MAX): New macros.
(quotearg_n_options): Abort if N is negative.
Avoid overflow check on hosts where size_t is 64 bits and int
is 32 bits, as overflow is impossible there.
Fix off-by-one typo that caused unnecessary reallocation.
