* src/LR0.c, src/closure.c, src/derives.c, src/gram.c, src/lalr.c * src/nullable.c, src/output.c, src/print.c, src/reader.c * src/reduce.c: Allocate and free from &rules[0], not &rules[1]. Iterate from 0 to nrules. Use rule_number_as_item_number and item_number_as_rule_number. Adjust to `derive' now containing possibly 0. * src/gram.h (rule_number_as_item_number, item_number_as_rule_number): Handle the `- 1' part in rule numbers from/to item numbers. * src/conflicts.c (log_resolution): Fix the message which reversed shift and reduce. * src/output.c (action_row): Initialize default_rule to -1. (token_actions): Adjust. * tests/sets.at (Nullable, Firsts): Fix the previously bogus expected output. * tests/conflicts.at (Resolved SR Conflicts): Likewise.
This directory contains the Bison parser generator. See the file INSTALL for compilation and installation instructions. See the file doc/FAQ for frequently asked questions. 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'. VMS and MS-DOS builds are probably broken right now. If you are able to build Bison on either platform and you need to make changes to do so, please submit those changes as a bug report. Send bug reports to bug-bison@gnu.org. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison which the documentation does not answer, send mail to help-bison@gnu.org.
