Everything in the compiler is compiled as an # rlib/dylib pair but all crates.io crates tend to just be rlibs. This means # we've got a problem for dependency graphs that look like: # # foo - rustc_trans # / \ # rustc ---- rustc_driver # \ / # foo - rustc_metadata # # Here the crate `foo` is linked into the `rustc_trans` and the # `rustc_metadata` dylibs, meaning we've got duplicate copies! When we then # go to link `rustc_driver` the compiler notices this and gives us a compiler # error. # # To work around this problem we just add these crates.io dependencies to the # `rustc` crate which is a shared dependency above. That way the crate `foo` # shows up in the dylib for the `rustc` crate, deduplicating it and allowing # crates like `rustc_trans` to use `foo` *through* the `rustc` crate. # # tl;dr; this is not needed to get `rustc` to compile, but if you remove it then # later crate stop compiling. If you can remove this and everything # compiles, then please feel free to do so! flate2 = "0.2"
