f805dfcb3f
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/Makefile.am (bison_SOURCES): Add AnnotationList.c, AnnotationList.h, InadequacyList.c, InadequacyList.h, Sbitset.c, Sbitset.h, ielr.h, and ielr.c. * 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.
