	# Install miscellaneous LLVM tools.
	#
	# These tools are already provided in the SDK, but they're built with
	# the version of LLVM built by sys-devel/llvm. Rust uses an independent
	# version of LLVM, so the use of these tools is sometimes necessary to
	# produce artifacts that work with `rustc` and such.
	#
	# Our long-term plan is to have Rust using the same version of LLVM as
	# sys-devel/llvm. When that happens, all of the below will be removed, with
	# the expectation that users will migrate to the LLVM tools on `$PATH`.
