…rics export). Includes the anticipated fallout to run-make-fulldeps test suite from this change. (We need to reopen issue 64319 as part of landing this.)
(Many thanks to alex for 1. making this even smaller than what I had originally minimized, and 2. pointing out that there is precedent for having ui tests with crate dependency chains of length > 2, thus allowing me to avoid encoding this as a run-make test.)

…r=alexcrichton Revert PR 64324: dylibs export generics again (for now) As discussed on PR rust-lang#65781, this is a targeted attempt to undo the main semantic change from PR rust-lang#64324, by putting `dylib` back in the set of crate types that export generic symbols. The main reason to do this is that PR rust-lang#64324 had unanticipated side-effects that caused bugs like rust-lang#64872, and in the opinion of @alexcrichton and myself, the impact of rust-lang#64872 is worse than rust-lang#64319. In other words, it is better for us, in the short term, to reopen rust-lang#64319 as currently unfixed for now than to introduce new bugs like rust-lang#64872. Fix rust-lang#64872 Reopen rust-lang#64319

It seems like the PR this reverts (#64324) did not ever land into beta, so presumably this PR also does not need to land into beta. De-nominating. |
