Its value can be "LALR", "IELR", or "canonical LR". * lib/timevar.def (TV_IELR_PHASE1): New var. (TV_IELR_PHASE2): New var. (TV_IELR_PHASE3): New var. (TV_IELR_PHASE4): New var. * src/local.mk (src_bison_SOURCES): Add AnnotationList.c, AnnotationList.h, InadequacyList.c, InadequacyList.h, Sbitset.c, Sbitset.h, ielr.c, and ielr.h. * src/getargs.h, src/getargs.c (enum trace, trace_args, trace_types): Add trace_ielr. * src/lalr.h, src/lalr.c (ngotos): Export it. (F): Rename to... (goto_follows): ... this, update all uses, and export it. (set_goto_map): Export it. (map_goto): Export it. (compute_lookahead_tokens): Don't free goto_follows yet. Now handled in ielr. (initialize_LA): Export it. Move lookback allocation to... (lalr): ... here because, for canonical LR, initialize_LA must be invoked but lookback and much of the rest of LALR isn't needed. * main.c (main): Instead of lalr, invoke ielr, which invokes lalr. * src/reader.c (reader): Default lr.type to "LALR". Default lr.default_rules to "accepting" if lr.type is "canonical LR". Leave the default as "all" otherwise. Check for a valid lr.type value. * src/state.h, src/state.c (struct state_list): Add state_list member. (state_new): Initialize state_list member to NULL. (state_new_isocore): New function, exported. * tests/existing.at (AT_TEST_EXISTING_GRAMMAR): New macro that exercises all values of lr.type. (GNU AWK Grammar): Rename test group to... (GNU AWK 3.1.0 Grammar): ... this, and extend to use AT_TEST_EXISTING_GRAMMAR. (GNU Cim Grammar): Extend to use AT_TEST_EXISTING_GRAMMAR. (GNU pic Grammar): Rename test group to... (GNU pic (Groff 1.18.1) Grammar): ... this, and extend to use AT_TEST_EXISTING_GRAMMAR. * tests/reduce.at (AT_TEST_LR_TYPE): New macro that exercises all values of lr.type. (Single State Split): New test groups using AT_TEST_LR_TYPE. (Lane Split): Likewise. (Complex Lane Split): Likewise. (Split During Added Lookahead Propagation): Likewise.
This package contains the GNU Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the section FAQ in the documentation (doc/bison.info) for frequently asked questions. The documentation is also available in PDF and HTML, provided you have a recent version of Texinfo installed: run "make pdf" or "make html". Bison requires GNU m4 1.4.6 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz Bison can work with pre-1.4.6 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.6 as the first step in trying to fix it. Please 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 and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005, 2008 Free Software Foundation, Inc.
