* src/output.c (prepare): Add prefixed names. (output_parser): Output semantic actions. (output_parser): Fix bug on '%%line' directives. 2001-08-19 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_rule_data): Do not output tables to the table obstack. * src/reader.c (reader): Remove calls to 'output_headers' and 'output_trailers'. Remove some C output. (readgram): Disable a piece of code that was writing a default definition for 'YYSTYPE'. (reader_output_yylsp): Remove. (packsymbols): Output token defintions to a macro. (copy_definition): Disable C output. * src/output.c (output_headers): Remove. The C code printed by this function should now be in the skeletons. (output_trailers): Remove. (output): Disable call to 'reader_output_yylsp'. 2001-08-18 Robert Anisko <robert.anisko@epita.fr> * src/output.c: Remove some C dedicated output. 2001-08-18 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_defines): Remove. 2001-08-18 Robert Anisko <robert.anisko@epita.fr> * src/output.c: Improve the use of macro and output obstacks. 2001-08-18 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_token_translations): Associate 'translate' table with a macro. No output to the table obstack. (output_gram): Same for 'rhs' and 'prhs'. (output_stos): Same for 'stos'. (output_rule_data): Same for 'r1' and 'r2'. (token_actions): Same for 'defact'. (goto_actions): Same for 'defgoto'. (output_base): Same for 'pact' and 'pgoto'. (output_table): Same for 'table'. (output_check): Same for 'check'. 2001-08-18 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_table_data): New function. (output_short_table): Remove. (output_short_or_char_table): Remove. 2001-08-17 Robert Anisko <robert.anisko@epita.fr> * src/main.c (main): Initialize the macro table. 2001-08-17 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_parser): Use the macro table. * src/macrotab.c: New file. * src/macrotab.h: New file. 2001-08-17 Robert Anisko <robert.anisko@epita.fr> * lib/xalloc.h (CALLOC, MALLOC, REALLOC): New macros. 2001-08-17 Robert Anisko <robert.anisko@epita.fr> * lib/hash.c: New file. * lib/hash.h: New file. 2001-08-16 Robert Anisko <robert.anisko@epita.fr> * src/reader.c (parse_macro_decl): Read macro identifiers using copy_identifier rather than lex. 2001-08-16 Robert Anisko <robert.anisko@epita.fr> * src/reader.c (copy_identifier): New. 2001-08-16 Robert Anisko <robert.anisko@epita.fr> * src/reader.c (read_declarations): Add case for macro definition. * src/lex.c (percent_table): Add tok_define. * src/lex.h: Add tok_define. 2001-08-16 Robert Anisko <robert.anisko@epita.fr> * src/reader.c (parse_macro_decl): New function used to parse macro declarations. (copy_string2): Put the body of copy_string into this new function. Add a parameter to let the caller choose whether he wants to copy the string delimiters or not. (copy_string): Be a simple call to copy_string2 with the last argument bound to true. 2001-08-15 Robert Anisko <robert.anisko@epita.fr> * src/output.c (output_parser): Replace most of the skeleton copy code with something new. Skeletons are now processed character by character rather than line by line, and Bison looks for '%%' macros. This is the first step in making Bison's output process (a lot) more flexible.
