RITEM. Note that it must be able to code symbol numbers as positive number, and the negation of rule numbers as negative numbers. Adjust all dependencies (pretty many). * src/reduce.c (rule): Remove this `short *' pointer: use item_number_t. * src/system.h (MINSHORT, MAXSHORT): Remove. Include `limits.h'. Adjust dependencies to using SHRT_MAX and SHRT_MIN. (shortcpy): Remove. (MAXTABLE): Move to... * src/output.c (MAXTABLE): here. (prepare_rules): Use output_int_table to output rhs. * data/bison.simple, data/bison.c++: Adjust. * tests/torture.at (Big triangle): Move the limit from 254 to 500. * tests/regression.at (Web2c Actions): Ajust. Trying with bigger grammars shows various phenomena: at 3000 (28Mb of grammar file) bison is killed by my system, at 2000 (12Mb) bison passes, but produces negative #line number, once fixed, GCC is killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of C), it passes. * src/state.h (state_h): Code input lines on ints, not shorts.
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.
