Hi all,

I want to use the LLVM_DISTRIBUTION_COMPONENTS support to create an installed toolchain image (via the install-distribution target). I'd also like the installed binaries to be stripped.

If you're invoking a cmake install script directly, you can pass -DCMAKE_INSTALL_DO_STRIP=1 to cmake to request stripping. The install-* targets set up by LLVM's build system don't seem to have any provision for this though, as far as I can tell. I also can't figure out a way to pass cmake this option apart from just putting it in the invocation (and the cmake invocation here is controlled by the install-* target).

I could go ahead and change the cmake invocation in all the install-* targets to (conditionally) enable stripping, but the creation of the various install-* targets is spread throughout the build system (a quick grep shows at least 20 of them spread around LLVM, clang, LLD, and libcxx), so it's a bit ugly. It's obviously not hard to do (just tedious), and I'll put up some patches for that if I can't figure out anything better, but I wanted to ask for suggestions before embarking down that route.
