@dyung Thanks.  That's exactly what I was looking for.  It looks like [lit is adding that directory here](https://github.com/llvm/llvm-project/blob/1d8985fc14457429c8120b09ae842250bdd225b1/llvm/utils/lit/lit/llvm/config.py#L46) based on the following [output from that windows bot](https://lab.llvm.org/buildbot/#/builders/216/builds/29020/steps/7/logs/stdio):

```
llvm-lit.py: Z:\b\llvm-clang-x86_64-sie-win\llvm-project\llvm\utils\lit\lit\llvm\config.py:46: note: using lit tools: C:\Program Files\Git\usr\bin
