Building on the work of # 45684 this commit updates the compiler to unconditionally load the `rustc_trans` crate at runtime instead of linking to it at compile time. The end goal of this work is to implement # 46819 where rustc will have multiple backends available to it to load. This commit starts off by removing the `extern crate rustc_trans` from the driver. This involved moving some miscellaneous functionality into the `TransCrate` trait and also required an implementation of how to locate and load the trans backend. This ended up being a little tricky because the sysroot isn't always the right location (for example `--sysroot` arguments) so some extra code was added as well to probe a directory relative to the current dll (the rustc_driver dll). Rustbuild has been updated accordingly as well to have a separate compilation invocation for the `rustc_trans` crate and assembly it accordingly into the sysroot. Finally, the distribution logic for the `rustc` package was also updated to slurp up the trans backends folder. A number of assorted fallout changes were included here as well to ensure tests pass and such, and they should all be commented inline. |
