This reverts commit 94c8bf5889a310cb758e89be0b3b066162013915.
Applied suggestions from code review Co-authored-by: Nikita Popov <github@npopov.com>
Before this commit, tests were invoked in multiple places, especially due to `-Z panic-abort-tests`, and adding a new test kind meant having to chase down and update all these places. This commit creates a new Runnable enum, and its children RunnableTest and RunnableBench. The rest of the harness will now pass around the enum rather than constructing and passing around boxed functions. The enum has two children enums because invoking tests and invoking benchmarks requires different parameters.
The inner function is not needed anymore as it's only called once after the previous commit's refactoring.
Before this commit, both static and dynamic benches were converted to a DynTestFn, with a boxed closure that ran the benchmarks exactly once. While this worked, it conflicted with -Z panic-abort-tests as the flag does not support dynamic tests. With this change, a StaticBenchFn is converted to a StaticBenchAsTestFn, avoiding any dynamic test creation. DynBenchFn is also converted to DynBenchAsTestFn for completeness.
This reverts commit 2050066.
Add `Read`, `Write` and `Seek` impls for `Arc<File>` where appropriate If `&T` implements these traits, `Arc<T>` has no reason not to do so either. This is useful for operating system handles like `File` or `TcpStream` which don't need a mutable reference to implement these traits. CC rust-lang#53835. CC rust-lang#94744.
Add gamma function to f32 and f64 Adds the [gamma function](https://en.wikipedia.org/wiki/Gamma_function) to `f32` and `f64` (`tgamma` and `tgammaf` from C). Refs: - rust-lang/rfcs#864 - rust-lang#18271
…=nikic Rebased: Mark drop calls in landing pads cold instead of noinline I noticed that certain inlining optimizations were missing while staring at some compiled code output. I'd like to see this relanded, so I rebased the PR from ``@erikdesjardins`` (PR rust-lang#94823). This PR reapplies rust-lang#92419, which was reverted in rust-lang#94402 due to rust-lang#94390. Fixes rust-lang#46515, fixes rust-lang#87055. Update: fixes rust-lang#97217.

Implement proposed API for `proc_macro_span` As proposed in [rust-lang#54725 (comment)](rust-lang#54725 (comment)). I have omitted the byte-level API as it's already available as [`Span::byte_range`](https://doc.rust-lang.org/nightly/proc_macro/struct.Span.html#method.byte_range). `@rustbot` label +A-proc-macros r? `@m-ou-se`
Always name the return place. MIR opts more and more consider `_0` as just another local, so there is no point in keeping the special case in debug-info logic.
[RFC-3086] Consider out-of-bound depths of `count` Fix rust-lang#111905 In the matching of macro calls and their respective declarations (transcribe), a warning is issued if `count` has a depth greater than the number of nested `NamedMatch`s through be verification of `MatchedSeq` with empty elements. Doesn't affect `( $( { $( [ $( ( $( $t:ident )* ) )* ] )* } )* ) => { ${count(t, 1)} }` called with `bar!( { [] [] } )` which will still continue to output `2`.
…ch, r=m-ou-se Test benchmarks with `-Z panic-abort-tests` During test execution, when a `#[bench]` benchmark is encountered it's executed once to check whether it works. Unfortunately that was not compatible with `-Z panic-abort-tests`: the feature works by spawning a subprocess for each test, which prevents the use of dynamic tests as we cannot pass closures to child processes, and before this PR the conversion from benchmark to test was done by turning benchmarks into dynamic tests whose closures execute the benchmark once. The approach this PR took was to add two new kinds of `TestFn`s: `StaticBenchAsTestFn` and `DynBenchAsTestFn` (:warning: **this is a breaking change** :warning:). With that change, a `StaticBenchFn` can be converted into a `StaticBenchAsTestFn` without creating dynamic tests, and making it possible to test `#[bench]` functions with `-Z panic-abort-tests`. The subprocess test runner also had to be updated to perform the conversion from benchmark to test when appropriate. Along with the bug fix, in the first commit I refactored how tests are executed: rather than executing the test function in multiple places across `libtest`, there is now a private `TestFn::into_runnable()` method, which returns either a `RunnableTest` or `RunnableBench`, on which you can call the `run()` method. This simplified the rest of the changes in the PR. This PR is best reviewed commit-by-commit. Fixes rust-lang#73509
… r=WaffleLapkin Better diagnostics for dlltool errors. When dlltool fails, show the full command that was executed. In particular, llvm-dlltool is not very helpful, printing a generic usage message rather than what actually went wrong, so stdout and stderr aren't of much use when troubleshooting.
Update LLVM submodule This adds rust-lang/llvm-project#147.
Enable zlib in LLVM on aarch64-apple-darwin Works on macOS 13.4, Xcode version 14.3.1.0.1.1683849156 This was disabled in rust-lang#75500 on Apple Silicon Developer Transition Kit, but Apple appears to have fixed their zlib now
…nted`-std-agnostic, r=WaffleLapkin Make `rustc_on_unimplemented` std-agnostic See rust-lang#112923 r? `@WaffleLapkin`
Use `CoverageKind::as_operand_id` instead of manually reimplementing it These two pieces of code are functionally equivalent to the `CoverageKind::as_operand_id` method that already exists, and is already used elsewhere in this file. This slightly reduces the amount of code that manually pattern-matches on `CoverageKind`.
…r=oli-obk Export AnalysisResults trait in rustc_mir_dataflow Followup to rust-lang#108293 Re-exports the new trait defined in mentioned PR to make ResultsCursor::seek_before_primary_effect, ResultsCursor::seek_after_primary_effect... usable again outside the compiler itself.
