(CXX): this, to keep the original Autoconf semantics. Require 2.57. * data/lalr1.cc: Fix b4_copyright invocations. If YYDEBUG is not defined, don't depend upon name_ being defined. (location.hh): Include string and iostream. (Position::filename): New member. (Position::Position ()): New. (operator<< (Position)): New. (operator- (Position, int)): New. (Location::first, Location::last): Rename as... (Location::begin, Location::end): these, to mock the conventional iterator names. (operator<< (Location)): New. * tests/atlocal.in (CXX): New. * tests/testsuite.at (AT_COMPILE_CXX): New. * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the locations in a more synthetic way. (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if lalr1.cc is used. Adjust the C locations to match those from Emacs: first column is column 0. Change all the expected results. Conform to the GCS: simplify the locations when applicable. (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS) (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace these CPP macros with the m4 macros new defined by... (AT_CHECK_PUSHDEFS): this, i.e.: (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS) (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALSm AT_LEX_PRE_ARGS) New macros. (AT_CHECK_POPDEFS): Undefine them. (AT_CHECK_CALC_LALR1_CC): New. Use it for the first lalr1.cc test.
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.
