Subject: Rollup merge of #50789 - cuviper:bootstrap-metadata, r=alexcrichton
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=e4f8132a32b8364c839864e32eeb42021ab37c6c;p=rust.git

Rollup merge of #50789 - cuviper:bootstrap-metadata, r=alexcrichton

Ensure libraries built in stage0 have unique metadata

Issue #50786 shows a case with local rebuild where the libraries built
by stage0 had the same suffix as stage0's own, and were accidentally
loaded by that stage0 rustc when compiling `librustc_trans`.

Now we set `__CARGO_DEFAULT_LIB_METADATA` to "bootstrap" during stage0,
rather than the release channel like usual, so the library suffix will
always be completely distinct from the stage0 compiler.
