<http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>. * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which evaluate to 0 if it's impossible for NINF to be in the respective table. (yygetLRActions, yyrecoverParseError): Use them. * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were counted in the token inserted at end of file. Now takes location_t *, not location_t, so that the location can be adjusted. All uses changed. * tests/regression.at (Invalid inputs): Adjust wording in diagnostic to match the new behavior. * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) abort ();'. This reduces the runtime of the "Many lookaheads" test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running GCC 3.2.
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.
