Comment (by alexcrichton):

 Ah that's a good point! I should probably have mentioned that earlier
 too... In any case you can set `RUSTFLAGS=-Csave-temps` and that'll spray
 a massive amount of files all over the place (`*.bc`, `*.o`, etc). You
 should be able to basically run a diff of all those files between builds,
 and you can probably pick the smallest one which has a difference in it.
 The `*.bc` files should also be natively disassemble-able by `llvm-dis`
