[CMake] Support separate installation of

Authored by phosek on Jul 10 2019, 2:42 PM.



This header fragment is useful on its own for any consumer that wants
to use custom instruction profile runtime with the LLVM instrumentation.
The concrete use case is in Fuchsia's kernel where we want to use
instruction profile instrumentation, but we cannot use the compiler-rt
runtime because it's not designed for use in the kernel environment.
This change allows installing this header as a separate distribution
component without having to install all LLVM headers.

You can use add_llvm_install_targets right?

LGTM with the comment; the use case makes sense to me.

I've changed the approach and moved this to compiler-rt which I think is a more appropriate place since this is related to the runtime.

Lgtm. There are a few more profile headers we’d like to expose for internal clients. Thanks for laying the groundwork.
