What the previous one was getting wrong is that sometimes it would<br>
output just the base destructor. If we are using aliases and<br>
implementing weak functions with comdats, we have to make sure every<br>
translation unit emits comdats with the same symbols. If we don't, the<br>
linker can decide to keep a copy that has only the base destructor and<br>
the link gets an undefined reference to the complete destructor.<br>

I have tested the patch by using a patched clang to build a debug<br>
version of clang.<br></blockquote><div><br></div><div>Since you've got it setup, have you run this against the GDB 7.5 test suite?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
