std::sync::mpsc uses thread locals and depending on the order TLS dtors are run `rx.recv()` can panic when used in a TLS dtor.
This controls whether run-* tests actually get run.
I was wary of doing any automatic disabling here, since should-fail is how we test compiletest itself.
I came up with this idea ages ago, but rustdoc used to ICE on it. Now it doesn't.
The comment says that build dependencies shouldn't matter unless they do some kind of codegen. It is safer to always check it though.
using allow_internal_unstable (as recommended) Fixes: rust-lang#84836 ```shell $ ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc src/test/run-make-fulldeps/coverage/no_cov_crate.rs error[E0554]: `#![feature]` may not be used on the dev release channel --> src/test/run-make-fulldeps/coverage/no_cov_crate.rs:2:1 | 2 | #![feature(no_coverage)] | ^^^^^^^^^^^^^^^^^^^^^^^^ error: aborting due to previous error For more information about this error, try `rustc --explain E0554`. ```
I just need this until rustbuild supports -Cpanic=abort std directly.
… thread 1 enters TLS destructors
This is a regression test for rust-lang#82820. This test case is included in more general tests, but I think the error regressed because there were a bunch of other diagnostic changes in the test that obscured this regression. Hopefully, having a test specific to the suggestion, and running rustfix for the test, will prevent this error from regressing in the future.
…r=jethrogb Ensure TLS destructors run before thread joins in SGX The excellent test is from ```@jethrogb``` For context see: rust-lang#83416 (comment)
…k-Simulacrum Add --run flag to compiletest This controls whether run-* tests actually get run. r? ```@Mark-Simulacrum```
…rk-Simulacrum Add test for suggestion to borrow unsized function parameters Closes rust-lang#82820. This is a regression test for rust-lang#82820. This test case is included in more general tests, but I think the error regressed because there were a bunch of other diagnostic changes in the test that obscured this regression. Hopefully, having a test specific to the suggestion, and running rustfix for the test, will prevent this error from regressing in the future.
…=Mark-Simulacrum Add `needs-unwind` and beginning of support for testing `panic=abort` std to compiletest For the Fuchsia platform we build libstd with `panic=abort` and would like a way to run tests with that enabled. This adds low-level support for this directly to compiletest. In the future I'd like to add high-level support in rustbuild, e.g. having target-specific flags that allow configuring a panic strategy. (Side note: It would be nice if we could also build multiple configurations for the same target, but I'm getting ahead of myself.) This plus rust-lang#84500 have everything that's needed to get ui tests passing on fuchsia targets. Part of rust-lang#84766. Note that this change only includes the header on tests which need an unwinder to _build_, not those which need it to _run_. r? ````@Mark-Simulacrum````
Allow using `core::` in intra-doc links within core itself I came up with this idea ages ago, but rustdoc used to ICE on it. Now it doesn't. Helps with rust-lang#73445. Doesn't fix it completely since `extern crate self as std;` in std still gives strange errors.
…, r=nagisa Disallows `#![feature(no_coverage)]` on stable and beta (using standard crate-level gating) Fixes: rust-lang#84836 Removes the function-level feature gating solution originally implemented, and solves the same problem using `allow_internal_unstable`, so normal crate-level feature gating mechanism can still be used (which disallows the feature on stable and beta). I tested this, building the compiler with and without `CFG_DISABLE_UNSTABLE_FEATURES=1` With unstable features disabled, I get the expected result as shown here: ```shell $ ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc src/test/run-make-fulldeps/coverage/no_cov_crate.rs error[E0554]: `#![feature]` may not be used on the dev release channel --> src/test/run-make-fulldeps/coverage/no_cov_crate.rs:2:1 | 2 | #![feature(no_coverage)] | ^^^^^^^^^^^^^^^^^^^^^^^^ error: aborting due to previous error For more information about this error, try `rustc --explain E0554`. ``` r? ````@Mark-Simulacrum```` cc: ````@tmandry```` ````@wesleywiser````
Wire up tidy dependency checks for cg_clif Also contains a fix and improvement to tidy. Required for rust-lang#81746.
Handle incorrect placement of parentheses in trait bounds more gracefully Fix rust-lang#84772. CC ``````@jonhoo``````
CTFE engine: rename copy → copy_intrinsic, move to intrinsics.rs The `copy` name is confusing for this function because we also have `copy_op` which is pretty different. I hope `copy_intrinsic` is clearer. Also `step.rs` should really just contain the main loop and opcode dispatch, so move this helper function to a more appropriate place. r? ``````@oli-obk``````
…_default_session_globals, r=jyn514 Remove unneeded call to with_default_session_globals in rustdoc highlight This was the origin of the `Span` bug in rust-lang#84176. cc `````@Aaron1011````` r? `````@jyn514`````
