+
+ * dwarf2expr.h (struct dwarf_expr_context): Add ADDR_SIZE member.
+ (dwarf2_read_address): Update prototype.
+
+ * dwarf2expr.c (unsigned_address_type): Add ADDR_SIZE parameter.
+ (signed_address_type): Likewise.
+ (dwarf2_read_address): Replace BYTES_READ parameter with ADDR_SIZE.
+ (execute_stack_op): Update calls to unsigned_address_type,
+ signed_address_type and dwarf2_read_address. Fix implementation
+ of DW_OP_deref_size.
+
+ * dwarf2loc.h (dwarf2_per_cu_objfile): Add prototype.
+ (dwarf2_per_cu_addr_size): Likewise.
+ (struct dwarf2_locexpr_baton): Replace OBJFILE with PER_CU.
+ (struct dwarf2_loclist_baton): Likewise.
+
+ * dwarf2loc.c (find_location_expression): Update calls to
+ dwarf2_read_address. Use dwarf2_per_cu_objfile and
+ dwarf2_per_cu_addr_size to retrieve PER_CU parameters.
+ (locexpr_describe_location): Likewise.
+ (dwarf2_evaluate_loc_desc): Replace OBJFILE with PER_CU parameter.
+ Set ctx->addr_size to dwarf2_per_cu_addr_size (per_cu).
+ (dwarf2_loc_desc_needs_frame): Add PER_CU parameter. Set ctx->addr_size
+ to dwarf2_per_cu_addr_size (per_cu).
+ (locexpr_read_variable): Update dwarf2_evaluate_loc_desc call.
+ (loclist_read_variable): Likewise.
+ (locexpr_read_needs_frame): Update dwarf2_loc_desc_needs_frame call.
+
+ * dwarf2read.c (dwarf2_symbol_mark_computed): Set baton->per_cu
+ instead of baton->objfile.
+ (dwarf2_per_cu_obfile): New function.
+ (dwarf2_per_cu_addr_size): Likewise.
+
+ * dwarf2-frame.c (struct comp_unit): Move higher.
+ (struct dwarf2_cie): Add UNIT and ADDR_SIZE members.
+ (execute_stack_op): Add ADDR_SIZE parameter; set ctx->addr_size.
+ (execute_cfa_program): Add FDE parameter. Replace EH_FRAME_P
+ parameter by using fde->eh_frame_p. Use read_encoded_value
+ to implement DW_CFA_set_loc.
+ (struct dwarf2_frame_cache): Add ADDR_SIZE member.
+ (dwarf2_frame_cache): Set cache->addr_size. Update calls to
+ execute_stack_op and execute_cfa_program.
+ (dwarf2_frame_prev_register): Update calls to execute_stack_op.
+ (size_of_encoded_value): Remove.
+ (read_encoded_value): Add PTR_LEN and FUNC_BASE parameters.
+ Remove call to size_of_encoded_value. Implement DW_EH_PE_funcrel.
+ (add_cie): Set cie->unit backlink.
+ (decode_frame_entry_1): Set cie->addr_size. Update calls to
+ read_encoded_value.
+ (dwarf2_build_frame_info): Allocate UNIT on objfile obstack.
