40 # Note that these dependencies are a lie, they're just here to get linkage to
43 # We're creating a bunch of dylibs for the compiler but we're also compiling a
44 # bunch of crates.io crates. Everything in the compiler is compiled as an
45 # rlib/dylib pair but all crates.io crates tend to just be rlibs. This means
46 # we've got a problem for dependency graphs that look like:
48 # foo - rustc_codegen_llvm
50 # rustc ---- rustc_driver
52 # foo - rustc_metadata
54 # Here the crate `foo` is linked into the `rustc_codegen_llvm` and the
55 # `rustc_metadata` dylibs, meaning we've got duplicate copies! When we then
56 # go to link `rustc_driver` the compiler notices this and gives us a compiler
59 # To work around this problem we just add these crates.io dependencies to the
60 # `rustc` crate which is a shared dependency above. That way the crate `foo`
61 # shows up in the dylib for the `rustc` crate, deduplicating it and allowing
62 # crates like `rustc_codegen_llvm` to use `foo` *through* the `rustc` crate.
64 # tl;dr; this is not needed to get `rustc` to compile, but if you remove it then
65 # later crate stop compiling. If you can remove this and everything
66 # compiles, then please feel free to do so!
