The guard is the same guard for the include that is in `Unix.h` in support. The problem is `Unix.h` in support is in a subdirectory that I cannot easily add to the include path for this file, so instead I directly copied it over. ================ Comment at: llvm/unittests/Support/CMakeLists.txt:3 Support + TargetParser ) ---------------- fpetrogalli wrote: > Is this needed? The tests for TargetParser should not be here anymore, no? This is needed because the tests in Support still use the Triple - they are not testing the triple, they just choose whether to run the tests based on the triple.
