* dwarf2.h (enum dwarf_call_frame_info): Add
DW_CFA_def_cfa_expression.
* dwarf2out.c (union dw_cfi_oprnd_struct): Add a pointer to a
dw_loc_descr_struct entry.
(struct cfa_loc): New structure to track a CFA location.
(lookup_cfa): Take a cfa_loc parameter instead of a reg and an offset.
(lookup_cfa_1): Take a cfa_loc parameter instead of a reg and an
offset, plus handle DW_CFA_def_cfa_expression.
(def_cfa_1): Use to be dwarf2out_def_cfa, only now it uses a
cfa_loc record.
(dwarf2out_def_cfa): Entry point maintained for compatability.
(dwarf_cfi_name): Add DW_CFA_def_cfa_expression.
(cfa_reg, cfa_offset): Replace with cfa_loc record 'cfa'.
(cfa_store_reg, cfa_store_offset): Replace with cfa_loc 'cfa_store'.
(initial_return_save, dwarf2out_stack_adjust): Use cfa.reg, not
cfa_reg.
(dwarf2out_frame_debug_expr): Use new cfa_loc records. Recognize rtl
sequences for the new DW_CFA_def_cfa_expression record.
(dwarf2out_frame_debug): Use new variables/fields.A
(output_cfi): Handle DW_CFA_def_cfa_expression.
(output_cfa_loc): New function to generate a CFI record for
DW_CFA_def_cfa_expression.
(get_cfa_from_loc_descr): New function to get a cfa_loc record from
a dw_loc_descr sequeunce.
(build_loc_descr): Build a dw_loc_descr from a cfa_loc record.
(dwarf_stack_op_name, new_loc_descr, add_loc_descr, size_of_loc_descr,
size_of_locs, output_loc_operands, output_loc_sequence): Move into
unwind info section.
* frame.h (frame_state): Add base_offset and indirect fields.
* frame-dwarf2.c (decode_stack_op): New function to interpret a
dw_loc_descr operation.
(execute_cfa_insn): Add support for DW_CFA_def_cfa_expression.
(struct frame_state): Add base offset and indirect fields.
* libgcc2.c (next_stack_level): Support indirect loading for CFA.
