[Thomas Preud'homme via Phabricator via llvm-commits]

thopre added inline comments.


================
Comment at: llvm/docs/CommandGuide/lit.rst:381
+ **standalone_tests** Mark a directory with tests expected to be run
+ standalone. Test discovery is disabled for that directory and
+ *--no-indirectly-run-check* is in effect.

I think a mix of discoverable tests and non discoverable ones is indeed unlikely and also non desirable because then when adding a new tests if it is not discoverable you cannot know whether it was intentional or an error (e.g. suffixes should have been modified to add a new suffix).

I'm reluctant to use suffixes being unset to disable the indirect check because not setting it might have been an error (i.e. someone creates a new directory, adds tests and a config name but forgets the suffixes). Besides suffixes is not used for all lit format (googletest ignores it).
