[llvm-dev] Failing unit tests

[David Blaikie via llvm-dev]

Given that the LLVM project runs a variety of automated validation
regularly on build bots (& many developers run the tests locally), it may
require a bit more investigation (possibly on your part) & debugging to
figure out why these are failing for you and presumably not for everyone
else.
