-/// Compiles the `compiler-rt` library, or at least the builtins part of it.
-///
-/// Note that while compiler-rt has a build system associated with it, we
-/// specifically don't use it here. The compiler-rt build system, written in
-/// CMake, is actually *very* difficult to work with in terms of getting it to
-/// compile on all the relevant platforms we want it to compile on. In the end
-/// it became so much pain to work with local patches, work around the oddities
-/// of the build system, etc, that we're just building everything by hand now.
-///
-/// In general compiler-rt is just a bunch of intrinsics that are in practice
-/// *very* stable. We just need to make sure that all the relevant functions and
-/// such are compiled somewhere and placed in an object file somewhere.
-/// Eventually, these should all be written in Rust!
-///
-/// So below you'll find a listing of every single file in the compiler-rt repo
-/// that we're compiling. We just reach in and compile with the `gcc` crate
-/// which should have all the relevant flags and such already configured.
-///
-/// The risk here is that if we update compiler-rt we may need to compile some
-/// new intrinsics, but to be honest we surely don't use all of the intrinsics
-/// listed below today so the likelihood of us actually needing a new intrinsic
-/// is quite low. The failure case is also just that someone reports a link
-/// error (if any) and then we just add it to the list. Overall, that cost is
-/// far far less than working with compiler-rt's build system over time.
