The skipped test passes since nightly-2024-11-29. Let's stop skipping it to increase the chance of detecing a regression.
Signed-off-by: xizheyin <xizheyin@smail.nju.edu.cn>
compiletest has confusingly two terminology to refer to the same concept -- "headers" and "directives". To make this more self-consistent and less confusing, stick with "directives" only. This commit **intentionally** tries to be limited to move-only (modulo some key usage reference renames) to help git history.
Explain `TOCTOU` on the top of `std::fs`, and reference it in functions Fixes rust-lang#141837 r? ```@workingjubilee```
…ilee Expose elf abi on ppc64 targets Fixes rust-lang#60617 (after MCP rust-lang/compiler-team#885 is accepted) by exposing the abi information on ppc64 targets. Conditional compilation can now use `cfg(target_abi = "elfv1")` or `cfg(target_abi = "elfv2")` to determine the abi in use. Technical details are included in the other PR rust-lang#142598
ci: aarch64-gnu: Stop skipping `panic_abort_doc_tests` The skipped test passes since `nightly-2024-11-29`. See rust-lang#123733 (comment) and rust-lang#123733 (comment) for more info. Let's stop skipping it to increase the chance of detecting a regression. r? ```@cuviper``` who added the skip in rust-lang#123828 Also see rust-lang#142304 for an alternative regression test that I am hoping to also land in the near future to complement the test we now stop skipping, but I need to investigate that setup more.
…-traits, r=tgross35 avoid suggesting traits from private dependencies fixes rust-lang#142676 fixes rust-lang#138191 r? ```@tgross35```
…-bitcast, r=workingjubilee fix bitcast of single-element SIMD vectors in effect this reverts rust-lang#142768 and adds additional tests. That PR relaxed the conditions on an early return in an incorrect way that would create broken LLVM IR. https://godbolt.org/z/PaaGWTv5a ```rust #![feature(repr_simd)] #[repr(simd)] #[derive(Clone, Copy)] struct S([i64; 1]); #[no_mangle] pub extern "C" fn single_element_simd(b: S) -> i64 { unsafe { std::mem::transmute(b) } } ``` at the time of writing generates this LLVM IR, where the type of the return is different from the function's return type. ```llvm define noundef i64 ```@single_element_simd(<1``` x i64> %b) unnamed_addr { start: ret <1 x i64> %b } ``` The test output is actually the same for the existing tests, showing that the change didn't actually matter for any tested behavior. It is probably a bit faster to do the early return, but, well, it's incorrect in general. zullip thread: [#t-compiler > Is transmuting a &rust-lang#96;T&rust-lang#96; to &rust-lang#96;Tx1&rust-lang#96; (one-element SIMD vector) UB?](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Is.20transmuting.20a.20.60T.60.20to.20.60Tx1.60.20.28one-element.20SIMD.20vector.29.20UB.3F/with/526262799) cc ```@sayantn``` r? ```@scottmcm```

Suggest use another lifetime specifier instead of underscore lifetime cc rust-lang#143152 r? compiler
…, r=Kobzol [COMPILETEST-UNTANGLE 3/N] Use "directives" consistently within compiletest Instead of using *both* "headers" and "directives" within compiletest to refer to the same thing. This of course induces some churn, but it's been bugging me for a while, and I rather do the self-consistency changes now than later. The first commit tries to be mostly move-only to help per-file git history. I intend to revisit rustc-dev-guide's testing docs, but I don't want to do it on rust-lang/rust side because it would need syncing and might conflict.
…e, r=oli-obk Don't recompute `DisambiguatorState` for every RPITIT in trait definition The `associated_type_for_impl_trait_in_trait` currently needs to rerun the `RPITVisitor` for every RPITIT to compute its disambiguator. Instead of synthesizing all of the RPITITs def ids one at a time in different queries, just synthesize them inside of the `associated_types_for_impl_traits_in_associated_fn` query. There we can just share the same `DisambiguatorState` for all the RPITITs in one function signature. r? ```@Zoxc``` or ```@oli-obk``` cc rust-lang#140453
Use the correct export kind for __rust_alloc_error_handler_should_panic Fixes rust-lang#143253 `__rust_alloc_error_handler_should_panic` is a static but was being exported as a function. For most targets this doesn't matter, but Arm64EC Windows uses different decorations for exported variables vs functions, hence it fails to link when `-Z oom=abort` is enabled. Fix is to export the symbol as data. r? ```@bjorn3```
