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

Hi All, Chandler,

After listening to Chandlers presentation at Going native 2013,

I think "lld" should add a buildbot configuration to turn on building 
lld with -fsanitize options and have buildbot configurations to run on

* darwin
* linux (ubuntu).

I was not really sure on if llvm changes use a buildbot with the 
-fsanitize options turned on / how stable the llvm libraries are when 
compiled using those options.

Does it make sense to have

* llvm built in the normal way
* just build lld with the options -fsanitize=address,undefined,memory 
options ?

(or)

* build all the sources including lld with the options 
-fsanitize=address,undefined,memory

Has anyone done this experiment already ?

Thanks

There are existing Darwin and Win7 builders, and a few Debian configs that also
build lld. I'd support enabling the sanitizers on these builds as is. Also,
tsan especially because lld uses threads.

If you'd like an Ubuntu bot, somebody is going to have to provide one.

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
