2023-03-08Remove `identity_future` indirectionArpad Borsos-357/+145
This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm. Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]` annotation.
2023-03-01Auto merge of #108476 - saethlin:remove-library-rustc-box, r=thomccbors-9/+7
Remove or document uses of #[rustc_box] in library r? `@thomcc` Only one of these uses is tested for in the rustc-perf benchmark suite. The impact there on compile time is somewhat dramatic, but I am inclined to make this change as a simplification to the library and wait for people to complain if it explodes their compilation time. I think in the absence of data or reports from users about what code paths really matter, if we are optimizing for compilation time, it's hard to argue against using `#[rustc_box]` everywhere we currently call `Box::new`.

2023-03-01Rollup merge of #108376 - liushuyu:fix-sysroot-infer-103660, r=ozkanonurMatthias Krüger-1/+11
compiler/rustc_session: fix sysroot detection logic This pull request fixes the sysroot detection logic on systems where `/usr/lib` contains a multi-arch structure (e.g. installs `rustc_driver` into `/usr/lib/x86_64-linux-gnu` folder). This fixes a regression for various Linux systems introduced in #103660. On Debian and Ubuntu systems, the logic in the pull request, as mentioned earlier, will resolve the sysroot to `/usr/lib`, making `rustc --print target-libdir` to return `/usr/lib/lib/rustlib/x86_64-unknown-linux-gnu/lib` (notice the extra `lib` at the beginning). The fix is not very "clean" according to the standard. If you have any suggestions on improving the logic, you are more than welcome to comment below!
2023-03-01Rollup merge of #108558 - RalfJung:core-tests, r=thomccMatthias Krüger-0/+1
add missing feature in core/tests https://github.com/rust-lang/rust/pull/104265 introduced the `ip_in_core` feature. For some reason core tests seem to still build without that feature -- no idea how that is possible. Might be related to https://github.com/rust-lang/rust/issues/15702? I was under the impression that `pub use` with different stability doesn't actually work. That's why `intrinsics::transmute` is stable, for example. Either way, core tests fail to build in miri-test-libstd, and adding the feature fixes that. r? ```@thomcc```

Stabilize `#![feature(target_feature_11)]` ## Stabilization report ### Summary Allows for safe functions to be marked with `#[target_feature]` attributes. Functions marked with `#[target_feature]` are generally considered as unsafe functions: they are unsafe to call, cannot be assigned to safe function pointers, and don't implement the `Fn*` traits. However, calling them from other `#[target_feature]` functions with a superset of features is safe. ```rust // Demonstration function #[target_feature(enable = "avx2")] fn avx2() {} fn foo() { // Calling `avx2` here is unsafe, as we must ensure // that AVX is available first. unsafe { avx2(); } } #[target_feature(enable = "avx2")] fn bar() { // Calling `avx2` here is safe. avx2(); } ``` ### Test cases Tests for this feature can be found in [`src/test/ui/rfcs/rfc-2396-target_feature-11/`](https://github.com/rust-lang/rust/tree/b67ba9ba208ac918228a18321fc3a11a99b1c62b/src/test/ui/rfcs/rfc-2396-target_feature-11/). ### Edge cases - https://github.com/rust-lang/rust/issues/73631 Closures defined inside functions marked with `#[target_feature]` inherit the target features of their parent function. They can still be assigned to safe function pointers and implement the appropriate `Fn*` traits. ```rust #[target_feature(enable = "avx2")] fn qux() { let my_closure = || avx2(); // this call to `avx2` is safe let f: fn() = my_closure; } ``` This means that in order to call a function with `#[target_feature]`, you must show that the target-feature is available while the function executes *and* for as long as whatever may escape from that function lives. ### Documentation - Reference: https://github.com/rust-lang/reference/pull/1181 --- cc tracking issue #69098 r? `@ghost`
2023-02-27Auto merge of #108487 - cjgillot:no-typeck-mir, r=oli-obkbors-207/+223
Avoid invoking typeck from borrowck This PR attempts to reduce direct dependencies between typeck and MIR-related queries. The goal is to have all the information transit either through THIR or through dedicated queries that avoid depending on the whole `TypeckResults`. In a first commit, we store the type information that MIR building requires into THIR. This avoids edges between mir_built and typeck. In the second and third commit, we wrap informations around closures (upvars, kind origin and user-provided signature) to avoid borrowck depending on typeck information. There should be a single remaining borrowck -> typeck edge in the good path, due to inline consts.
