+ * TODO: Add request from Nelson H. F. Beebe to be able to install
+ Bison without installing the yacc script.
+
+2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
+ and yytext if they're already #define'd.
+ * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
+ * src/scan-code-c.c: ... here.
+ * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
+ <config.h>.
+
+2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Get Bison to build again when configured with --enable-gcc-warnings.
+ * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
+ missing #include's.
+ * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
+ loc argument as it shadows a global.
+ * src/scan-gram.l: Remove stray comma that prevents boundary_set
+ invocation.
+
+ * src/.cvsignore: Add scan-code.c.
+
+2006-06-07 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l: Move the "add a trailing ; to actions" code
+ to...
+ * src/scan-code.l: here.
+ * tests/input.at (Torturing the Scanner): Fix another location
+ error.
+
+2006-06-07 Akim Demaille <akim@epita.fr>
+
+ * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.

+
+ Extract the parsing of user actions from the grammar scanner.
+ As a consequence, the relation between the grammar scanner and
+ parser is much simpler. We can also split "composite tokens" back
+ into simple tokens.
+ * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
+ * src/scan-gram.l (add_column_width, adjust_location): Move to and
+ rename as...
+ * src/location.h, src/location.c (add_column_width)
+ (location_compute): these.
+ Fix the column count: the initial column is 0.
+ (location_print): Be robust to ending column being 0.
+ * src/location.h (boundary_set): New.
+ * src/main.c: Adjust to scanner_free being renamed as
+ gram_scanner_free.
+ * src/output.c: Include scan-code.h.
+ * src/parse-gram.y: Include scan-gram.h and scan-code.h.
+ Use boundary_set.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
+ (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
+ which is now, again, a separate token.
+ Adjust all dependencies.
+ Whereever actions with $ and @ are used, use translate_code.
+ (action): Remove this nonterminal which is now useless.
+ * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
+ (grammar_current_rule_action_append): Use translate_code.
+ (packgram): Bound check ruleno, itemno, and rule_length.
+ * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
+ (last_string, last_braced_code_loc, max_left_semantic_context)
+ (scanner_initialize, scanner_free, scanner_last_string_free)
+ (gram_out, gram_lineno, YY_DECL_): Move to...
+ * src/scan-gram.h: this new file.
+ (YY_DECL): Rename as...
+ (GRAM_DECL): this.
+ * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
+ * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+ (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
+ (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+ Move these declarations, and...
+ (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
+ these to...
+ * src/flex-scanner.h: this new file.
+ * src/scan-gram.l (rule_length, rule_length_overflow)
+ (increment_rule_length): Remove.
+ (last_braced_code_loc): Rename as...
+ (gram_last_braced_code_loc): this.
+ Adjust to the changes of the parser.
+ Move all the handling of $ and @ into...
+ * src/scan-code.l: here.
+ * src/scan-gram.l (handle_dollar, handle_at): Remove.
+ (handle_action_dollar, handle_action_at): Move to...
+ * src/scan-code.l: here.
+ * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
+ scan-code.h, scan-code-c.c, scan-gram.h.
+ (EXTRA_bison_SOURCES): Add scan-code.l.
+ (BUILT_SOURCES): Add scan-code.c.
+ (yacc): Be robust to white spaces.
+
+ * tests/conflicts.at, tests/input.at, tests/reduce.at,
+ * tests/regression.at: Adjust the column numbers.
+ * tests/regression.at: Adjust the error message.
