 Replying to [comment:5 ryandesign]:
 > Why twice for i386?
 My [https://rustc-dev-guide.rust-lang.org/building/bootstrapping.html
 understanding] is that the x86_64 upstream stage0 compiler builds an
 x86_64 stage1 compiler which in turn builds an i386 stage2 compiler.\\

 > If rust is building its own private copy of llvm every time, yes,
 putting it in another port or subport could make a lot of sense. Maybe
 there are times when you are making a change to the port that only affects
 the private llvm, or only rust, so you could revbump just that subport and
 not have to rebuild the other part.

 There was a time when Rust [https://github.com/macports/macports-
 ports/commit/4c5878867bdeb08e5d8c394a76598343cefd081a used the MacPorts
 LLVM].\\
 However the [https://trac.macports.org/ticket/61082 consensus] was that it
 was too difficult to keep track of [https://github.com/rust-lang/llvm-
 project/ Rust's LLVM fork].
