* dwarf2read.c: Replace integral tag, name and form fields in

Browse Source 
internal structure definitions with the corresponding enumeration
	types from dwarf2.h. Add default cases to switches on enumerations
	where appropriate.
	Make quoting of string arguments in complaint messages consistent.
	Check for NULL returns from DW_STRING.
	(struct partial_die_info):  Add sibling and has_type fields, remove
	unused value field.
	(DW_*):  Move access macro definitions near the definition of the
	attribute structure.
	(struct field_info):  New structure to pass information about fields
	and member functions between die processing routines.
	(dwarf2_build_psymtabs_hard):  Set cu_header_offset.
	(scan_partial_symbols):  Do not enter DW_TAG_subprogram dies into
	the partial symbol table if the DW_AT_*_pc attributes are missing.
	Add file scope base type definitions to the partial symbol table.
	Skip over child dies if the die has a sibling attribute.
	(add_partial_symbol):  Enter global variables with type attributes
	and without location descriptors into the partial symbol table.
	Store value of DW_TAG_variable dies in the partial symbol table.
	Do not enter global variables into the minimal symbol table.
	Add base type definitions to the partial symbol table.
	(psymtab_to_symtab_1):  Use dwarf2_get_pc_bounds to determine highpc.
	(process_die):  Move check for DW_AT_low_pc to read_func_scope.
	Add a typedef symbol for base type definitions to the symbol table.
	Ignore DW_TAG_inlined_subroutine tags for now.
	(read_file_scope):  Use dwarf2_get_pc_bounds to determine pc bounds.
	(read_func_scope, read_lexical_block_scope):  Use dwarf2_get_pc_bounds
	to determine pc bounds, ignore dies with invalid bounds.
	(dwarf2_get_pc_bounds):  New routine to extract and validate the
	DW_AT_*_pc attributes of a die.
	(dwarf2_add_field, dwarf2_attach_fields_to_type, skip_member_fn_name,
	dwarf2_add_member_fn, dwarf2_attach_fn_fields_to_type):
	New functions to handle fields and member functions.
	(read_structure_scope):  Rewritten to use them.
	(read_array_type):  Renamed from dwarf_read_array_type.
	Default upper array bound to describe an array with unspecified
	length.
	Create array types in backwards order, as dwarf2 puts out the array
	dimensions from left to right.
	(read_subroutine_type):  Handle DW_TAG_unspecified_parameters,
	DW_AT_artificial and DW_AT_prototyped.
	(read_base_type):  Make an unsigned type for DW_ATE_boolean.
	Pass objfile to dwarf_base_type.
	(read_partial_die):  Use read_attribute to read in the attributes.
	Handle DW_AT_sibling and DW_AT_type.
	Follow references when determining DW_AT_name and DW_AT_external
	attributes of the die.
	Validate DW_AT_*_pc attributes.
	(read_full_die):  Use read_attribute to read in the attributes.
	(read_attribute):  New function to read an attribute described
	by an abbreviated attribute.
	(new_symbol):  Relocate symbol value for DW_TAG_label with baseaddr.
	Do not set SYMBOL_VALUE_ADDRESS for DW_TAG_subprogram,
	SYMBOL_BLOCK_VALUE for the symbol will be set later by finish_block.
	Change symbol class for global variables with a zero valued location
	descriptor to LOC_UNRESOLVED.
	Handle DW_AT_const_value attributes for DW_TAG_variable,
	DW_TAG_formal_parameter and DW_TAG_enumerator.
	Build a typedef symbol for DW_TAG_base_type.
	(dwarf2_const_value):  New routine to copy a constant value from an
	attribute to a symbol.
	(dwarf_base_type):  Use passed in objfile, not current_objfile
	when calling dwarf2_fundamental_type.
	(dump_die):  Use DW_* accessor macros to access values of attributes.
	(decode_locdesc):  Handle DW_OP_plus_uconst.
