(readgram): Use `#if 0' around code that accepted %command inside grammar rules: The documentation doesn't allow it, and it will fail since the %command processors scan for the next %. (parse_token_decl): Extended the %token declaration to allow a multi-character symbol as an alias. (parse_thong_decl): New function. (read_declarations): Added %thong declarations. (read_declarations): Handle NOOP to deal with allowing % declarations as another means to specify the flags. (readgram): Allow %prec prior to semantics embedded in a rule. (skip_to_char, read_declarations, copy_definition) (parse_token_decl, parse_start_decl, parse_type_decl) (parse_assoc_decl, parse_union_decl, parse_expect_decl) (get_type_name, copy_guard, copy_action, readgram) (get_type, packsymbols): Revised most error messages. Changed `fatal' to `warnxxx' to avoid aborting for error. Revised and use multiple warnxxx functions to avoid using VARARGS1. (read_declarations): Improve the error message for an invalid character. Do not abort. (read_declarations, copy_guard, copy_action): Use printable_version to avoid unprintable characters in printed output. (parse_expect_decl): Error if argument to %expect exceeds 10 digits. (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type): Allow the type of a non-terminal can be given more than once, as long as all specifications give the same type.
This directory contains the Bison parser generator. See the file INSTALL for compilation and installation instructions. It was once true that, when installing Bison on Sequent (or Pyramid?) systems, you had to be in the Berkeley universe. This may no longer be true; we have no way to tell. On VMS, you will probably have to create Makefile from Makefile.in by hand. Remember to do `SET COMMAND BISON' to install the data in `BISON.CLD'. Send bug reports to bug-gnu-utils@prep.ai.mit.edu. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report.
