binutils-gdb/gdb/configure.in
Peter Schauer 0db3fe94c3 Add support for Irix 6.2 native O32 and N32 ABI. 
* config.in, configure.in, configure:  Check for <objlist.h>.
	* configure.tgt:  Handle mips*-sgi-irix6* like irix5 for now.

	* cp-valprint.c (cp_print_value_fields):  Use SYMBOL_VALUE_ADDRESS
	instead of SYMBOL_BLOCK_VALUE to get the address of a static member.

	* dwarf2read.c:  Turn warnings and recoverable errors into complaints,
	add new complaints where appropriate.
	gcc -Wall cleanup.
	(struct line_head):  Change line_base from char to int to avoid
	problems with compilers whose plain char is represented by an
	unsigned char.
	(struct partial_die_info):  Add is_declaration field.
	(dwarf2_tmp_obstack):  New obstack for allocating temporary storage
	used during symbol reading.
	(cu_header_offset):  New variable for resolving relative reference
	dies.
	(optimized_out, basereg, islocal, frame_base_reg, frame_base_offset):
	New interface variables for decode_locdesc.
	(struct dwarf2_pinfo):  New structure for communication between
	psymtab and symtab reading, passed via pst->read_symtab_private.

	without line number sections.
	(dwarf2_build_psymtabs_hard):  Initialize temporary obstack
	for symbol reading.
	Allocate and initialize pst->read_symtab_private.
	Relocate pst->textlow and pst->texthigh with baseaddr.
	(scan_partial_symbols):  Do not add DW_AT_declaration symbols
	to the partial symbol table.
	Add file scope enumerator symbols to the partial symbol table.
	Fix typo in highpc computation.
	If we didn't find a lowpc, set it to highpc to avoid complaints
	from `maint check.
	(add_partial_symbol):  Relocate symbol values with baseaddr.
	Add static DW_TAG_subprogram and DW_TAG_variable symbols to the
	minimal symbol table.
        Obtain symbol values for DW_TAG_variable symbols from the location
	descriptor, skip symbols with missing location desciptors.
	Skip symbols for aggregate types without children.
	Handle enumerator symbols.
	(dwarf2_psymtab_to_symtab):  Issue symbol reading message if verbose.
	(psymtab_to_symtab_1):  Set local variables from
	pst->read_symtab_private, set cu_header_offset and baseaddr.

	buildsym and add a cleanup to really_free_pendings.

	If the compilation is from a C file generated by language
	preprocessors, do not set the symtab language if it was already
	deduced by start_subfile.
	Removed verbose sorting symbol table message.
	(process_die):  Handle DW_TAG_ptr_to_member_type and
	DW_TAG_reference_type.
	Use read_subroutine_type to get the function type for
	DW_TAG_subprogram before calling read_func_scope.
	(read_file_scope):  Initialize file name to <unknown>, start_subfile
	expects a non-NULL name.
	If we didn't find a lowpc, set it to highpc to avoid complaints
	from finish_symbol.
	Relocate lowpc and highpc with baseaddr.
	Get rid of Irix6.2 native cc compile machine prefix in comp_dir.
	Zero out ftypes for each new compilation unit (may be different
	language or different objfile).
	Accept compilation units without line number information, pass
	comp_dir to decode_lines.
	(read_func_scope):  Initialize function name to <unknown> to avoid
	core dumps when DW_AT_name is missing.

	Create array type only if a DW_TAG_subrange_type was found.
	(read_tag_pointer_type, read_tag_reference_type):
	Use lookup_pointer_type and lookup_reference_type instead
	of handcrafting a type.
	(read_tag_ptr_to_member_type):  New function to handle
	DW_TAG_ptr_to_member_type.

	Use lookup_function_type instead of handcrafting a type.
	(read_typedef):  Allocate a TYPE_CODE_TYPEDEF type for the typedef.
	(read_base_type):  If the type has a name, use init_type to create
	a new type instead of second guessing a fundamental type.
	(read_comp_unit):  Reset die reference table before building
	a new one.
	(dwarf2_read_section):  Read section contents into psymbol_obstack.

	New routines to get signed values from a buffer.
	(read_n_bytes, read_string):  Allocate storage from the temporary
	obstack. If the host char size permits it, return pointer
	to buffer instead of allocating storage.
	(set_cu_language):  Handle DW_LANG_Mips_Assembler.
	(dwarf_attr):  Return NULL if reference die for DW_AT_specification
	or DW_AT_abstract_origin die is not found.
	(record_minimal_symbol):  Removed, replaced with a direct call to
	prim_record_minimal_symbol, it now handles saving the string itself.
	(convert_locdesc):  Removed, partial symtab reading now uses
	decode_locdesc.
	(dwarf_attr):  Use dwarf2_get_ref_die_offset to get the absolute
	offset for the die reference.
	(dwarf_decode_lines):  Complain if the line section info is missing.

        problems with compilers whose plain char is represented by an
        unsigned char.
	Add cleanups for allocated temporary storage.
	Start a subfile for the first file in the state machine.
	Fix off by one problem with dirs.dirs access.
	Use comp_dir when directory index is 0.

	(dwarf2_start_subfile):  Try to keep line numbers from identical
	absolute and relative file names in a common subfile.
	(new_symbol):  Allocate symbol and symbol name on the symbol_obstack.
	Set SYMBOL_LINE from DW_AT_decl_line if present.
	Set SYMBOL_TYPE from passed type if not NULL.

	known as LOC_UNRESOLVED symbols.
	Synthesize typedefs for C++ classes, structs, unions and enumerations.
	Handle DW_TAG_enumerator symbols, complain for unrecognized
	symbol tags.
	(die_type):  A missing DW_AT_type represents a void type.

	reference table.

	(dwarf_alloc_block):  Allocate block on temporary obstack.

	* elfread.c (elf_symtab_read):  When handling Irix dynamic symbols,
	skip section name symbols and relocate all others.
	(elf_symfile_read):  Build dwarf2 psymtab even if offset is non-zero.

	from N32 executables. Call registers_fetched after extracting
	the registers.
	(obj_list_variant, struct link_map, LM_OFFSET, LM_ADDR):  New
	definitions to enable support of O32 and N32 format objlists.
