[hadrian] Use LLVM for test and validate target

Hi all, Is it possible to force Hadrian to use the LLVM code generator for the test and validate targets? For example, while using the following commands it seems to me that only the native code generator (if available) is used: $ ./hadrian/build -c -j --flavour=quick-llvm test $ ./hadrian/build -c -j --flavour=validate Cheers, Stefan
