I guess e.g. ia64_expand_prologue could add all those regs that it
/* Even if we're not going to generate an epilogue, we still
need to save the register so that EH works. */
if (! epilogue_p)
emit_insn (gen_prologue_use (XXX_reg));
when epilogue_p as USEs into CALL_INSN_FUNCTION_USAGE of all noreturn calls.
