Add case + Op_K_case to handle switch. + Add cases Op_K_do, Op_K_while, Op_K_for, Op_K_arrayfor, Op_K_switch + and Op_K_default as no-ops, needed for pgawk. + * debug.c (print_instruction): Remove case Op_K_switch, + add case Op_K_case instead. + + Unrelated: + * awkgram.y (case_statements): As case values, "abc" and /abc/ + no longer considered as duplicates. + + Cleanup grammar and run-time code for switch and loops. + Jump targets for break and continue are now fixed, and known + at parse time. See ChangeLog entry dated Oct 21, 2010. + + * awk.h (OPCODE): Remove Op_push_loop and Op_pop_loop. + (loop_count): Remove definition. + * awkgram.y (fix_break_continue): Change calling parameters to + instruction list, break and continue targets.
