Use the hash node as Node_param_list; + Saves a NODE for each parameter. + (install_params): Install function parameters into the symbol + table. + (remove_params): Remove parameters out of the symbol table. + * awk.h (parmlist, FUNC): Nuked. + (fparms): New define. + + + Dynamically loaded function parameters are now handled like + those for a builtin. + + * awk.h (Node_ext_func, Op_ext_builtin): New types. + (Op_ext_func): Nuked. + * ext.c (make_builtin): Simplified. + (get_curfunc_arg_count): Nuked; Use the argument 'nargs' of + the extension function instead. + (get_argument, get_actual_argument): Adjust. + * eval.c (r_interpret): Update case Op_func_call for a dynamic + extension function. Handle the new opcode Op_ext_builtin. + * pprint (profile.c): Adjust. + + + Use a single variable to process gawk options. + + * awk.h (do_flags): New variable. + (DO_LINT_INVALID, DO_LINT_ALL, DO_LINT_OLD, DO_TRADITIONAL, + DO_POSIX, DO_INTL, DO_NON_DEC_DATA, DO_INTERVALS, + DO_PROFILING, DO_DUMP_VARS, DO_TIDY_MEM, + DO_SANDBOX): New defines. + (do_traditional, do_posix, do_intervals, do_intl, + do_non_decimal_data, do_profiling, do_dump_vars, + do_tidy_mem, do_sandbox, do_lint, + do_lint_old): Defined as macros. + * main.c: Remove definitions of the do_XX variables. Add + do_flags definition. + * debug.c (execute_code, do_eval, parse_condition): Save + do_flags before executing/parsing and restore afterwards. + + + Nuke PERM flag. Always increment/decrement the reference + count for a Node_val. Simplifies macros and avoids + occassional memory leaks, specially in the debugger. + + * awk.h (UPREF, DEREF, dupnode, unref): Simplified. + (mk_number): Nuked. + * (*.c): Increment the reference count of Nnull_string before + assigning as a value. + + + Revamped array handling mechanism for more speed and + less memory consumption. + + * awk.h (union bucket_item, BUCKET): New definitions. Used as + bucket elements for the hash table implementations of arrays; + 40% space saving in 32 bit x86. + (buckets, nodes, array_funcs, array_base, array_capacity, + xarray, alookup, aexists, aclear, aremove, alist, + acopy, adump, NUM_AFUNCS): New defines. + (array_empty): New macro to test for an empty array. + (assoc_lookup, in_array): Defined as macros. + (enum assoc_list_flags): New declaration. + (Node_ahash, NUMIND): Nuked. + * eval.c (r_interpret): Adjust cases Op_subscript, + Op_subscript_lhs, Op_store_var and Op_arrayfor_incr. + * node.c (dupnode, unref): Removed code related to Node_ahash. + * str_array.c: New file to handle array with string indices. + * int_array.c: New file to handle array with integer indices. + * cint_array.c: New file. Special handling of arrays with + (mostly) consecutive integer indices. + + + Memory pool management reworked to handle NODE and BUCKET. + + * awk.h (struct block_item, BLOCK, block_id): New definitions. + (getblock, freeblock): New macros. + (getbucket, freebucket): New macros to allocate and deallocate + a BUCKET. + (getnode, freenode): Adjusted. + * node.c (more_nodes): Nuked. + (more_blocks): New routine to allocate blocks of memory. + 2011-08-24 Arnold D.
