* parser-defs.h (struct exp_descriptor): New definition, containing
language-specific info for printing, prefixifying, dumping, and evaluating expressions. (exp_descriptor_standard): Declare new variable. (print_subexp): Make global and declare here (from expprint.c). (dump_subexp): Ditto. (dump_subexp_body_standard): Declare. (operator_length_standard): Declare. (op_name_standard): Declare. (print_subexp): Declare. (print_subexp_standard): Declare. * language.h (struct language_defn): Add la_exp_desc field to hold pointer to table for language-specific operators. Remove evaluate_exp field, which is now in struct exp_descriptor. * parse.c (operator_length): Move most code to new operator_length_standard function. Use language-specific information. (operator_length_standard): New function taking most code from operator_length. (exp_descriptor_standard): New constant. * expression.h (enum exp_opcode): Add definitions of OP_EXTENDED0 and OP_EXTENDED_LAST. * expprint.c (print_subexp): Use language-specific print_subexp. Make global; remove static declaration. Move most code to print_subexp_standard. (print_subexp_standard): New function, containing code formerly in print_subexp. (op_name): Add expression to argument signature. Use langauge-specific op_name. Move most code to op_name_standard. (op_name_standard): New function, containing code formerly in op_name. (dump_subexp): Use new version of op_name function. Use language-specific dump_subexp_body, and move most existing code to dump_subexp_body_standard. (dump_raw_expression): Use new op_name interface. (dump_subexp_body): Move most code to dump_subexp_body_standard. (dump_subexp_body_standard): New function, containing code formerly in dump_subexp_body. * language.c (unknown_language): Add default la_exp_desc field and remove evaluate_exp field. (auto_language): Ditto. (local_language): Ditto. * f-lang.c (f_language_defn): Ditto. * c-lang.c (c_language_defn): Ditto. (cplus_language_defn): Ditto. (asm_language_defn): Ditto. (minimal_language_defn): Ditto. * p-lang.c (pascal_language_defn): Ditto. * m2-lang.c (m2_language_defn): Ditto. * objc-lang.c (objc_language_defn): Ditto. * jv-lang.c (exp_descriptor_java): New variable, containing Java-specific expression evaluator. (java_language_defn): Add la_exp_desc field and remove evaluate_exp field. * scm-lang.c (exp_descriptor_scm): New variable, containing Scheme-specific expression evaluator. (scm_language_defn): Add la_exp_desc field and remove evaluate_exp field. * objc-lang.c (print_object_command): Take evaluate_exp from the la_exp_desc field. * Makefile.in (eval.o): Add dependency on parser-defs.h. * eval.c: Include parser-defs.h for the full declaration of la_exp_desc's type. (evaluate_subexp): Get evaluate_exp out of la_exp_desc field.
