Had to tweak linking options in target spec to make it work (see moturus/motor-os#46).
There is no compelling reason to use this alias instead of the full target name.
add larger test for `proc_macro` `FromStr` implementations Currently, there are only few tests that check the output of `TokenStream::from_str` and `Literal::from_str` (which is somewhat understandable as the rustc implementation just delegates these calls to the parser). In preparation for both the standalone backend (rust-lang#130856) which will probably need to reimplement this logic as well as for removing panics from these functions (rust-lang#58736), this PR adds a test which shows the various messy ways of how these functions report errors and the return values for successful parses. Followup PRs such as rust-lang#147859 will change more and more of these "diagnostic + error"s into `LexErrors`. The test structure with the extra module is used to allow reusing it later easily for the standalone backend.

Error if an autodiff user does not set lto=fat Based on your feedback, I started to provide a nice error message for a lack of `lto=fat`, instead of us forcing it. In a next step, we should replace `RUSTFLAGS="-Zautodiff=Enable"` with another Cargo.toml setting, as discussed here: rust-lang#147487 (comment) As another improvement, we should also figure out why rlib builds do not properly obey the fat=lto setting. ```````@bjorn3```````
add note to `lines` docs about empty str behavior This pull request adds a short note to the documentation for `str::lines` that describes the behavior of the resulting iterator when called on an empty string. I tripped over this a few days ago because I thought (incorrectly) that the iterator would return a single line with an empty string. I don't doubt that the actual behavior (return no lines) is the correct behavior, but in the absence of explicit documentation describing it, I came to the wrong conclusion about it and maybe others will too. If this is so obvious as to be not worth including, I'm happy to withdraw the pull request! Thanks for taking a look.
Run codegen tests on a 32-bit target in PR CI wasm32-wasip1 is the wasm target used in test-various. So using it somewhere else seems like a good bet.
…up, r=jieyouxu Abi compatibility test cleanup r? `@jieyouxu` - moves `NonNull` (and some friends) into `minicore.rs` so it can be re-used. - tests the abi compatibility of a couple more targets. It's useful to have a comprehensive overview of all ABIs that rust has some amount of support for, e.g. testing for c-variadic or guaranteed tail calls (cc rust-lang#148748)
…ouxu Tweak Motor OS linker preset, fix `remote-test-server` for Motor OS Had to tweak linking options in target spec to make it work (see moturus/motor-os#46).
… r=jieyouxu compiletest: Avoid race condition in file deletion Fixes rust-lang#149003 There is a TOCTOU when multiple threads attempt to delete the same file. Instead of pre-checking if the file exists, we can simply ignore `NotFound` errors.
…ouxu triagebot: remove jsha from notifications for rustdoc HTML See rust-lang/team#2083 - I'm moving to alumni status for rustdoc and no longer need these notifications.
compiletest: Remove the "wasm32-bare" alias for `wasm32-unknown-unknown` - Follow-up to rust-lang#148969 This "wasm32-bare" alias, understood by compiletest's `//@ ignore-wasm32-bare` and `//@ only-wasm32-bare` directives, dates all the way back to the original introduction of the `wasm32-unknown-unknown` target in rust-lang#45905. But there is no compelling reason to use an alias instead of the full target name. r? jieyouxu
