3 * src/LR0.c (insert_start_shift): Rename as...
4 (insert_start_shifting_state): this.
5 (insert_eof_shifting_state, insert_accepting_state): New.
6 (augment_automaton): Adjust.
7 Better locality of the variables.
8 When looking if the start_symbol is shifted from the initial
9 state, using `while (... symbol != start_symbol ...)' sounds
10 better than `while (... symbol < start_symbol ...)': If fail
11 to see how the order between symbols could be relevant!

15 * src/getargs.h: Don't declare `spec_name_prefix' and
16 `spec_file_prefix', declared by src/files.h.
17 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
19 * src/output.c (prepare): Adjust.
20 * src/reader.c (symbols_output): Likewise.
21 * src/vmsgetargs.c: Vaguely adjust, but who cares?

26 * src/muscle_tab.c (muscle_init): NULL is a better default than
27 `"0"'.

32 * src/reader.c (reader): Calling symbols_output once is enough.

37 Now that states have a complete set of members, the linked list of
38 reductions is useless: just fill directly the state's reductions
39 member.
40
41 * src/state.h (struct reductions): Remove member `number' and
42 `next'.
43 * src/LR0.c (first_reduction, last_reduction): Remove.
44 (save_reductions): Don't link the new reductions, store them in
45 this_state.
46 * src/lalr.c (set_state_table): No need to attach reductions to
47 states, it's already done.
48 * src/output.c (output_actions): No longer free the shifts, then
49 the reductions, then the states: free all the states and their
50 members.

55 * src/options.c (OPTN, DRTV, BOTH): New.
56 (option_table): Use them.
57
58
59 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
60 the job of system.h.
61 * src/options.c: Don't include stdio.h and xalloc.h for the same
62 reasons.

67 * src/output.c (output, prepare): Make sure the values of the
68 muscles `action' and `prologue' are 0-terminated.

72 Clean up GCC warnings.
73
74 * src/reader.c (copy_action): `buf' is not used.
75 (parse_skel_decl): Be static.
76 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
77 * src/options.h (create_long_option_table): Have a real prototype.
78 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
79 (hash_delete_at): Return const void *.
80 Adjust casts to preserve the const.

84 * configure.in: Require 2.52g.

92 One structure for states is enough, even though theoretically
93 there are LR(0) states and LALR(1) states.
94
95 * src/lalr.h (state_t): Remove.
96 (state_table): Be state_t **, not state_t *.
97 * src/state.h (core, CORE_ALLOC): Rename as...
98 (state_t, STATE_ALLOC): this.
99 Add the LALR(1) members: shifts, reductions, errs.
100 * src/LR0.c (state_table): Rename as...
101 (state_hash): this, to avoid name clashes with the global
102 `state_table'.
103 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
104 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

109 Bison dumps core on bash.y.
110 Reported by Pascal Bart.
111
112 * src/warshall.c (bitmatrix_print): New.
113 (TC): Use it.
114 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
115 j must be the outer loop.
116 * tests/regression.at (Broken Closure): New.

121 its argument.
