> Incorrect. There is also a zero_call_used_regs attribute.
Thanks, now I've found it in your tree:
```
You can control this behavior for a specific function by using the function
attribute @code{zero_call_used_regs}.
```
Could you explain the connection between your attribute for zeroing registers
and 'no_caller_saved_registers' attribute?
