# Note that these dependencies are a lie, they're just here to get linkage to
|
|
# work.
|
|
#
|
|
# We're creating a bunch of dylibs for the compiler but we're also compiling a
|
|
# bunch of crates.io crates. 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!
