handle negative $ indices or $ indices in embedded rules correctly. See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>. (b4_rhs_value): Change to use YYFILL macro. (b4_rhs_location): Ditto. (yyfill): New function to copy from stack tree into array incrementally. (yyuserAction): Modify to allow incremental move of semantic values to rhs array when in GLR mode. Define YYFILL to use in user-defined actions to fill semantic array as needed. Remove dummy use of yystack, as there is now a guaranteed use. (yydoAction): Modify to allow incremental move of semantic values to rhs array when in GLR mode. (yyresolveAction): Ditto. (yyglrShiftDefer): Update comment. (yyresolveStates): Use X == NULL for pointers, not !X. (yyglrReduce): Ditto. (yydoAction): Ditto
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.
