(declaration): Replace expected_conflicts with expected_sr_conflicts.
Add %expect-rr rule.
* src/scan-gram.l: Recognize %expect-rr.
* src/conflicts.h (expected_sr_conflicts): Rename from
expected_conflicts.
(expected_rr_conflicts): Declare.
* src/conflicts.c (expected_sr_conflicts): Rename from
expected_conflicts.
(expected_rr_conflicts): Define.
(conflicts_print): Check r/r conflicts against expected_rr_conflicts
for GLR parsers.
Use expected_sr_conflicts in place of expected_conflicts.
Warn if expected_rr_conflicts used in non-GLR parser.
* doc/bison.texinfo: Add documentation for %expect-rr.
* src/LR0.c (new_state): Set it to 0.
* src/conflicts.h, src/conflicts.c (print_conflicts)
(free_conflicts, solve_conflicts): Rename as...
(conflicts_print, conflicts_free, conflicts_solve): these.
Adjust callers.
* src/conflicts.c (enum conflict_resolution_e)
(solved_conflicts_obstack): New, used by...
(log_resolution): this.
Adjust to attach the conflict resolution to each state.
Complete the description with the precedence/associativity
information.
(resolve_sr_conflict): Adjust.
* src/print.c (print_state): Output its solved_conflicts.
* tests/conflicts.at (Unresolved SR Conflicts)
(Solved SR Conflicts): Exercise --report=all.
(resolve_sr_conflict, set_conflicts, solve_conflicts)
(count_sr_conflicts, count_rr_conflicts, conflicts_output)
(conflicts_print, print_reductions): Use a state_t instead of an
integer when referring to a state.
As much as possible, depend upon nlookaheads, instead of the
`lookaheadsp' member of the following state (since lookaheads of
successive states are successive, the difference between state n + 1
and n served as the number of lookaheads for state n).
* src/lalr.c (add_lookback_edge): Likewise.
* src/print.c (print_core, print_actions, print_state)
(print_results): Likewise.
* src/print_graph.c (print_core, print_actions, print_state)
(print_graph): Likewise.
* src/conflicts.h: Adjust.
