New Revision: 273104
URL: http://llvm.org/viewvc/llvm-project?rev=273104&view=rev
Log:
Add UBSan blacklist for <__tree> and <__hash_table>
We all know <__tree> and <__hash_table> have plenty of UB that UBSan faithfully
finds. I am working on fixing this. However the noisy output from these failures
prevent automatically detecting regressions elsewhere.
This patch adds a blacklist file for these failures so I can later set up a
UBSAN buildbot.
