(enum address_class): Add LOC_COMPUTED and LOC_COMPUTED_ARG. (struct location_funcs): New type. (struct symbol): Add "loc" to aux_value. (SYMBOL_LOCATION_BATON, SYMBOL_LOCATION_FUNCS): New macros. * dwarf2read.c: Include "dwarf2expr.h". (dwarf2_symbol_mark_computed): New function. (read_func_scope): Use it. (var_decode_location): New function. (new_symbol): Use it. * dwarf2expr.c, dwarf2expr.h, dwarf2loc.c, dwarf2loc.h: New files. * Makefile.in (SFILES): Add dwarf2loc.c and dwarf2expr.c. (dwarf2expr_h, dwarf2loc_h): New variables. (COMMON_OBS): Add dwarf2expr.o and dwarf2loc.o. (dwarf2expr.o, dwarf2loc.o): New rules. (dwarf2read.o): Add $(dwarf2expr_h) and $(dwarf2loc_h). * buildsym.c (finish_block): Handle LOC_COMPUTED and LOC_COMPUTED_ARG. * findvar.c (symbol_read_needs_frame, read_var_value): Likewise. * m2-exp.y (yylex): Likewise. * printcmd.c (address_info, print_frame_args): Likewise. * stack.c (print_block_frame_locals, print_frame_arg_vars): Likewise. * symmisc.c (print_symbol, print_partial_symbols): Likewise. * ada-lang.c (ada_resolve_subexp, symtab_for_sym) (ada_add_block_symbols, fill_in_ada_prototype): Likewise. * symtab.c (lookup_block_symbol): Likewise. --- gdb/dwarf2loc.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gdb/dwarf2loc.h (limited to 'gdb/dwarf2loc.h') diff --git a/gdb/dwarf2loc.h b/gdb/dwarf2loc.h new file mode 100644 index 0000000..fde1329 --- /dev/null +++ b/gdb/dwarf2loc.h @@ -0,0 +1,39 @@ +/* Dwarf2 location expression support for GDB. + Copyright 2003 Free Software Foundation, Inc. + + This file is part of GDB. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
