[llvm-dev] [llvm-lit] Is it possible to write a test for Linux only?

[Taewook Oh via llvm-dev]

Maybe I was totally confused. When I see /test/lit.cfg (https://github.com/llvm-mirror/clang/blob/master/test/lit.cfg), some available_features are based on config.target_triple (e.g. https://github.com/llvm-mirror/clang/blob/master/test/lit.cfg#L420), so I though REQUIRES is not necessarily about $host.

    Because you're asking about REQUIRES, which refers to features of the 
    $host. If you just want to write a target dependent test, use -target / 
    -triple.
