	* 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.
