[LLVMdev] [lld] buildbot configuration on using -fsanitize options
Does it build with libstdc++?

[LLVMdev] [lld] buildbot configuration on using -fsanitize options
Hi Evgeniy, Can you add the step to checkout lld and build and run the unittests then ? Thanks Shankar Easwaran On 9/10/2013 4:59 AM, Evgeniy Stepanov wrote:> Does it build with libstdc++?

[LLVMdev] [lld] buildbot configuration on using -fsanitize options
The bootstrap bot currently builds with libstdc++. AFAIU, lld does not support that. It would need to be switched to libc++. Also, MSan uses a precompiled, instrumented libstdc++ binary, which should be replaced with libc++ built from source. We've got a script for it, which is not used at the moment: https://code.google.com/p/address-sanitizer/source/browse/trunk/build/scripts/slave/bootstrap/build_libcxx.sh This looks like a non-trivial amount of work that I would be not have time for in the near future. You are welcome to try.
