</span>Hi Lang,<br>
this is a relatively large change. For the future it would be nice if<br>
we can discuss this before checking in (e.g. on llvm-devel).<br>
That said, do you have an use-case for this? In the past we explicitly<br>
tried to not change return type from 'void' to 'std::error_code' just<br>
in case.<br>
<br>
Thanks!<br>
<br>
