llvm dev - Sep 2013 - [LLVMdev] [lld] buildbot configuration on using -fsanitize options

Hi Alex,

+ Galina

Ubuntu/Debian should work as well, I wanted one flavor where lld could 
be built on linux platform.

I will want to have a seperate buildbot to seperate failures if any due 
to the fsanitize options.

Do you know if llvm itself gets tested as a complete build with the 
fsanitize options ?

Enabling tsan seems to be a good idea too.

Thanks

Shankar Easwaran

Also, tsan especially because lld uses threads.

We test it very regularly with all of the sanitizers. We've not been able
to add these bots easily due to infrastructure issues.

Thanks for the info Chandler. I would like to add the extra fsanitize 
configs to the lld buildbot to detect problems early.

There have been a bunch of temporary string issues, which would have 
been easily caught by the sanitizer tools.

Thanks
