* Makefile.in (YYFILES): Add ch-exp.tab.c. * Makefile.in (YYOBJ): Add ch-exp.tab.o. * Makefile.in (saber_gdb): Add unload of ch-exp.y and load of ch-exp.tab.c. * Makefile.in (distclean): Add target ch-exp.tab.c. * Makefile.in (realclean): Add rm of ch-exp.tab.c. * Makefile.in (c-exp.tab.c, m2-exp.tab.c): Add dependency on Makefile since it contains sed patterns used in generation. Add sed pattern to also delete #include of any malloc.h. * Makefile.in (ch-exp.tab.o, ch-exp.tab.c): New targets. * ch-exp.y: New expression parser, for GNU-Chill. * c-exp.y, expr.c, expression.h, language.c, m2-exp.y, parser-defs.h, valarith.c, valops.c, value.h: Remap macros and function names to conform to K&R terminology with respect to logical and bitwise operators: UNOP_ZEROP => UNOP_LOGICAL_NOT UNOP_LOGNOT => UNOP_COMPLEMENT BINOP_LOGAND => BINOP_BITWISE_AND BINOP_LOGXOR => BINOP_BITWISE_XOR BINOP_LOGIOR => BINOP_BITWISE_IOR BINOP_AND => BINOP_LOGICAL_AND BINOP_OR => BINOP_LOGICAL_OR PREC_OR => PREC_LOGICAL_OR PREC_AND => PREC_LOGICAL_AND PREC_LOGIOR => PREC_BITWISE_IOR PREC_LOGXOR => PREC_BITWISE_XOR PREC_LOGAND => PREC_BITWISE_AND value_zerop() => value_logical_not() value_lognot() => value_complement() * c-exp.y (c_op_print_tab): Add explicit empty terminator. * m2-exp.y (m2_op_print_tab): Add explicit empty terminator. * defs.h (enum language): Add language_chill. * dwarfread.c (set_cu_language): Add LANG_CHILL case and make LANG_MODULA2 a recognized language. * eval.c (evaluate_subexp): Add OP_BOOL case. * expprint.c (print_subexp): Add OP_BOOL case. * gdbtypes.h (enum_typecode): Note TYPE_CODE_BOOL used for Chill as well as Modula-2. * gdbtypes.y (builtin_type_chill_bool, builtin_type_chill_long, builtin_type_chill_ulong, builtin_type_chill_real): Add. * i387-tdep.c (sys/dir.h): Remove, appears to be unnecessary and is nonexistant in some SVR4 based systems. * language.c (DEFAULT_ALLOCSIZE): Change from 3 => 4. * language.c (set_language_command): Add chill. * language.c (binop_result_type, integral_type, character_type, boolean_type, structured_type, value_true, binop_type_check): Add language_chill cases. * language.h (_LANG_chill): Define. * m2-exp.y (number_sign, modblock): Make static, #ifdef out unused modblock. * m2-exp.y (ANDAND): Rename to LOGICAL_AND. * source.c (source_info): Fix minor nits, print "1 line" rather than "1 lines", and "language is <lang>". * symfile.c (deduce_language_from_filename): Recognize the filename extensions ".chill", ".c186", and ".c286" for Chill. * valarith.c (value_binop): Handle TYPE_CODE_BOOL as well as TYPE_CODE_INT and TYPE_CODE_FLOAT. * valprint.c (val_print): Print TYPE_CODE_BOOL type values as "TRUE" or "FALSE". * valprint.c (typedef_print): Add case for language_chill. * values.c (value_from_longest): Handle TYPE_CODE_BOOL.
