# If the tests are broken, it's probably for one of two reasons:
#
# 1. The version of llvm used doesn't match the expectations of rustc and/or
# cargo-llvm-cov. This is relatively unlikely because we pull llvm out of
# rustc's attrset, so it *should* be the right version as long as this is the
# case.
# 2. Nixpkgs has changed its rust infrastructure in a way that causes
# cargo-llvm-cov to misbehave under test. It's likely that even though the
# tests are failing, cargo-llvm-cov will still function properly in actual
# use. This has happened before, and is described [here][0] (along with a
# feature request that would fix this instance of the problem).
#
# For previous test-troubleshooting discussion, see [here][1].
