+       lalr1.cc: get rid of yyparse's yystate.
+       yystate and yystack_[0].state are equal, keep only the latter.
+       The former was also used as a temporary variable to compute the
+       post-reduction state.  Move this computation into an auxiliary
+       function.
+
+       * data/glr.c (yyLRgotoState): Fuse variable definition and first
+       assignment.
+       * data/lalr1.cc (yy_lr_goto_state_): New.
+       (yyparse): Use it.
+       Replace remaining uses of yystate by yystate_[0].state.
+       Remove the former.
