compnerd created this revision.
compnerd added reviewers: xiaobai, beanz, smeenai.
Herald added a subscriber: mgorny.
Herald added a project: clang.
This adds the clang-cl and clang++ symlinks. Since there are no targets to
depend on for this, we cannot force the creation of the symlinks. Furthermore,
the current build only installs the symbolic links in the install tree, not the
build tree. This enables the use of the clang driver without having adjust the
C/C++ flags to add `--driver=...` to switch between driver modes. Usage of
this is present in Swift and there is some usage in lldb.
