* config/i386/i386-expand.cc (ix86_expand_call): Replace
no_caller_saved_registers check with call_saved_registers check.
Clobber all registers that are not used by the callee with
no_callee_saved_registers attribute.
* config/i386/i386-options.cc (ix86_set_func_type): Set
call_saved_registers to TYPE_NO_CALLEE_SAVED_REGISTERS for
noreturn function. Disallow no_callee_saved_registers with
interrupt or no_caller_saved_registers attributes together.
(ix86_set_current_function): Replace no_caller_saved_registers
check with call_saved_registers check.
(ix86_handle_no_caller_saved_registers_attribute): Renamed to ...
(ix86_handle_call_saved_registers_attribute): This.
(ix86_gnu_attributes): Add
ix86_handle_call_saved_registers_attribute.
* config/i386/i386.cc (ix86_conditional_register_usage): Replace
no_caller_saved_registers check with call_saved_registers check.
(ix86_function_ok_for_sibcall): Don't allow callee with
no_callee_saved_registers attribute when the calling function
has callee-saved registers.
(ix86_comp_type_attributes): Also check
no_callee_saved_registers.
(ix86_epilogue_uses): Replace no_caller_saved_registers check
with call_saved_registers check.
(ix86_hard_regno_scratch_ok): Likewise.
(ix86_save_reg): Replace no_caller_saved_registers check with
call_saved_registers check. Don't save any registers for
TYPE_NO_CALLEE_SAVED_REGISTERS. Save all registers with
TYPE_DEFAULT_CALL_SAVED_REGISTERS if function with
no_callee_saved_registers attribute is called.
(find_drap_reg): Replace no_caller_saved_registers check with
call_saved_registers check.
* config/i386/i386.h (call_saved_registers_type): New enum.
