+
+ Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.
+ * data/lalr1.cc (b4_tables_map): Move to...
+ * data/bison.m4: here.
+ Update the comment for yytable during the flight.
+ (b4_tables_declare, b4_tables_define): New.
+ * data/lalr1.cc: Use them.
+ * data/c.m4 (b4_table_define): New.
+ * data/yacc.c: Use b4_tables_define instead of output the tables
+ by hand.
+ * tests/regression.at (Web2c Actions): Adjust the expected output,
+ the order of the tables changed.
+
+2008-11-26 Akim Demaille <demaille@gostai.com>
+
+ Get rid of (yy)rhs and (yy)prhs.
+ These tables are no longer needed in the parsers, and they don't seem to
+ be useful. They are not documented either.
+
+ * src/output.c (prepare_rules): Get rid of rhs and prhs.
+ Adjust the computation of (yy)r2.
+
+2008-11-26 Akim Demaille <demaille@gostai.com>
+
+ Rule length is unsigned.
+ * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
+
+2008-11-26 Akim Demaille <demaille@gostai.com>
+
+ Get rid of lalr1-split.cc.
+ It was no longer maintainer.
+
+ * data/lalr1-split.cc: Remove.
+ * etc/bench.pl.in (bench_fusion_parser): Remove.
+ Adjust.
+
+2008-11-26 Akim Demaille <demaille@gostai.com>
+
+ Use yy* consistently.
+ * data/glr.c: Now that yyrhs no longer exists as a global
+ variable, rename local "rhs" variables into "yyrhs" for
+ consistency.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ Get rid of yyrhs and yyprhs in glr.c.
+ * data/glr.c (yyrhs, yyprhs): Remove.
+ Instead, use the state stack and yystos.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ Flag glr tests.
+ * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
+ as an Autotest keyword.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ Prefer TESTSUITE_FLAGS.
+ TESTSUITEFLAGS is barely readable.
+
+ * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
+ for backward compatibility.
+ Use the former instead of the latter.

+
+ Get rid of yyrhs and yyprhs in larl1.java.
+ * data/lalr1.java (yyrhs_, yyprhs_): Remove.
+ (yy_reduce_print): Rather, use yystos_ and the state stack.

+
+ Get rid of yyrhs and yyprhs in yacc.c.
+ They were used to get the symbol types, given a rule number, when
+ displaying the top of the stack before a reduction. But the symbol type
+ is available from the state stack. This has two be benefits: two tables
+ less in the parser (making it smaller), and a more consistent use of the
+ three stacks which will help to fuse them.
+
+ * data/yacc.c (yyprhs, yyrhs): Remove.
+ (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
+ (yy_reduce_print): Take yyssp as argument.
+ Use it, together with yystos, to get the symbol type.
+ * tests/regression.at (Web2c Report): Remove these tables from the
+ expected output.
+

+
+ b4_tables_map.
+ The point is to factor the generation of the tables across skeletons.
+ This is language dependant.
+
+ * data/c.m4 (b4_comment_): New.
+ Should be usable to define how to generate tables independently of
+ the language.
+ (b4_c_comment): New.
+ (b4_comment): Bounce to b4_c_comment.
+ Now support $2 = [PREFIX] for indentation.
+ * data/lalr1.cc (b4_table_declare): Don't output a comment if
+ there is no comment.
+ Indent it properly when there is one.
+ Output the ending semicolon.
+ (b4_table_define): Space changes.
+ Output the ending semicolon.
+ (b4_tables_map): New.
+ Use it twice instead of declaring and defining the (integral)
+ tables by hand.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ b4_table_declare.
+ * data/lalr1.cc (b4_table_declare): New.
+ Use it to declare the tables defined with b4_table_define.
+ (b4_table_define): Declare a third arg to match b4_table_declare
+ signature.
+ Move all the comments around invocations of b4_table_define into
+ the invocations itselves.
+ Move things around to have the order for declarations and
+ definitions.
