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. +

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

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. + Relocate lowpc and highpc with baseaddr. + Handle DW_AT_frame_base, keep result for DW_OP_fbreg operations. + Pass function type to new_symbol. + (read_lexical_block_scope): Relocate lowpc and highpc with baseaddr. + (read_structure_scope): Set TYPE_TAG_NAME, not TYPE_NAME. + Handle DW_TAG_class_type. + Copy fields to

TYPE_NAME. + Copy fields to type_obstack, release temporary storage for fields. + Let new_symbol handle the symbol creation for enumerators + instead of handcrafting a symbol. + Determine signedness of enum type from enumerators. + (dwarf_read_array_type): Handle variable length arrays. + Use lookup_pointer_type instead of handcrafting a type. + 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. + (read_subroutine_type): Handle parameter dies. + Use lookup_function_type instead of handcrafting a type. + (read_typedef): Allocate a TYPE_CODE_TYPEDEF type for
