(dwarf2_fetch_die_loc_cu_off): Rename from dwarf2_fetch_die_location_block. Rewrite to use dwarf2_fetch_die_loc_sect_off. * dwarf2loc.h (dwarf2_fetch_die_loc_sect_off): Declare. (dwarf2_fetch_die_loc_cu_off): Rename. * dwarf2loc.c (indirect_pieced_value): Use dwarf2_fetch_die_loc_sect_off. * dwarf2expr.h (struct dwarf_expr_context) <len, data>: Update comment. (struct dwarf_expr_piece) <v.ptr.die>: Now a sect_offset. * dwarf2expr.c (add_piece): Update. (execute_stack_op) <DW_OP_GNU_implicit_pointer>: Update comment. testsuite * gdb.dwarf2/implptr-64bit.exp: Run tests with two CUs as well. (test): Add "two_cu" argument. * gdb.dwarf2/implptr-64bit.S: Move subprogram later; use ref_addr for types; allow two CUs.
