`destroyed'), we now sometimes examine them, and store information related to them. Hence we need to know their number, and adjust memory allocations. * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer static. * src/LR0.c (allocate_itemsets): The memory allocated to `symbol_count' was used for two different purpose: once to count the number of occurrences of each symbol, and later reassigned to `shift_symbol', containing the symbol that can be shifted from a given state. Deobfuscate, i.e., allocate, use and free `symbol_count' here only, and... (new_itemsets): Allocate `shift_symbol' here. (allocate_itemsets): symbol_count includes useless nonterminals. Make room for them. (free_storage): Use `free', not `XFREE', for pointers that cannot be null.
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.
