How do tests like test/Shell/Register/x86*.test work in such standalone builds then? They use lines like these: # XFAIL: system-windows # REQUIRES: native && target-x86_64 # RUN: %clangxx -fomit-frame-pointer %p/Inputs/x86-64-gp-read.cpp -o %t # RUN: %lldb -b -s %s %t | FileCheck %s (The XFAIL for system-windows, at least in this test, when I tried it out, seemed to relate to the fact that `register read --all` on windows didn't include all the 32 bit subregisters.) If tests already can use such constrcuts, I don't see why we couldn't use `# RUN: %clang_cl ..`, as lit sets up `%clang_cl` in the same way as `%clangxx`.
