- Default to trying git rev-parse for the root directory CARGO_MANIFEST_DIR is a path on the build machine, not the running machine. Don't require this to succeed, to allow building from a tarball; in that case fall back to CARGO_MANIFEST_DIR. - Set `initial_rustc` to a path based on the path of the running executable, not CARGO_MANIFEST_DIR. We only reset `initial_rustc` if we're sure this isn't the working tree bootstrap was originally built in, since I'm paranoid that setting this in other cases will cause things to break; it's not clear to me when $RUSTC differs from `build/$TARGET/stage0/bin/rustc` (maybe never? but better to be sure). Instead, only set this when a) We are not using a custom rustc. If someone has specified a custom rustc we should respect their wishes. b) We are in a checkout of rust-lang/rust other than the one bootstrap was built in. |
