Extend flags to support multibit and enum bitfields.
gdb/ChangeLog:
Extend flags to support multibit and enum bitfields.
NEWS: Document new features.
* c-typeprint.c (c_type_print_varspec_prefix): Handle TYPE_CODE_FLAGS.
(c_type_print_varspec_suffix, c_type_print_base): Ditto.
* gdbtypes.c (arch_flags_type): Don't assume all fields are one bit.
(append_flags_type_field): New function.
(append_flags_type_flag): Call it.
* gdbtypes.h (append_flags_type_field): Declare.
* target-descriptions.c (struct tdesc_type_flag): Delete.
(enum tdesc_type_kind) <TDESC_TYPE_BOOL>: New enum value.
(enum tdesc_type_kind) <TDESC_TYPE_ENUM>: Ditto.
(struct tdesc_type) <u.f>: Delete.
(tdesc_predefined_types): Add "bool".
(tdesc_predefined_type): New function.
(tdesc_gdb_type): Handle TDESC_TYPE_BOOL, TDESC_TYPE_ENUM.
Update TDESC_TYPE_FLAGS support.
(tdesc_free_type): Handle TDESC_TYPE_ENUM. Update TDESC_TYPE_FLAGS.
(tdesc_create_flags): Update.
(tdesc_create_enum): New function.
(tdesc_add_field): Initialize start,end to -1.
(tdesc_add_typed_bitfield): New function.
(tdesc_add_bitfield): Call it.
(tdesc_add_flag): Allow TDESC_TYPE_STRUCT. Update.
(tdesc_add_enum_value): New function.
(maint_print_c_tdesc_cmd): Fold TDESC_TYPE_FLAGS support into
TDESC_TYPE_STRUCT. Handle TDESC_TYPE_ENUM.
* target-descriptions.h (tdesc_create_enum): Declare.
(tdesc_add_typed_bitfield, tdesc_add_enum_value): Declare.
* valprint.c (generic_val_print_enum_1): New function.
(generic_val_print_enum): Call it.
(val_print_type_code_flags): Make static. Handle multibit bitfields
and enum bitfields.
* valprint.h (val_print_type_code_flags): Delete.
* xml-tdesc.c (struct tdesc_parsing_data) <current_type_is_flags>:
Delete. All uses removed.
(tdesc_start_enum): New function.
(tdesc_start_field): Handle multibit and enum bitfields.
(tdesc_start_enum_value): New function.
(enum_value_attributes, enum_children, enum_attributes): New static
globals.
(feature_children): Add "enum".
* features/gdb-target.dtd (enum, evalue): New elements.
gdb/doc/ChangeLog:
* gdb.texinfo (Target Descriptions): New menu item "Enum Target Types".
(Target Description Format): Mention enum types. Update docs on
flags types.
(Predefined Target Types): Add "bool".
(Enum Target Types): New node.
gdb/testsuite/ChangeLog:
* gdb.xml/extra-regs.xml: Add enum, mixed_flags values.
