<br>
They're part of LLVM's representation of debugging information (as you<br>
may have guessed). So if compiling with Clang you can just not pass -g<br>
and you won't get any (or override with -g0 if your build system<br>
already adds -g and it's inconvenient to avoid that). Other front-ends<br>
will have similar options I expect.<br>
<br>
> If not, once I have the bc how can I remove all the occurrences?<br>
<br>
You can run "opt -strip-debug" will remove it in that situation.<br>
<br>
Cheers.<br>
<br>
Tim.<o:p></o:p></p>
