I've first tried option 4 via adding ``` $(LLVMInstallDir) $(LLVMToolsVersion) ``` to https://github.com/python/cpython/blob/8c87bcd7f2fd7ea5f731b5fd64ab261814ec892f/PCbuild/regen.targets#L122-L127 This would have been my preferred choice, because then we would not have to "teach something new"...

Implementing option 3 is easy, too: just add ``` $(LLVM_TOOLS_INSTALL_DIR) $(LLVM_VERSION) ``` after https://github.com/python/cpython/blob/8c87bcd7f2fd7ea5f731b5fd64ab261814ec892f/PCbuild/python.props#L30-L32 Now we'd have to document that when overriding the clang used to build the jit stencils...
