gpu offload host code generation r? ghost This will generate most of the host side code to use llvm's offload feature. The first PR will only handle automatic mem-transfers to and from the device. So if a user calls a kernel, we will copy inputs back and forth, but we won't do the actual kernel launch. Before merging, we will use LLVM's Info infrastructure to verify that the memcopies match what openmp offloa generates in C++. `LIBOMPTARGET_INFO=-1 ./my_rust_binary` should print that a memcpy to and later from the device is happening. A follow-up PR will generate the actual device-side kernel which will then do computations on the GPU. A third PR will implement manual host2device and device2host functionality, but the goal is to minimize cases where a user has to overwrite our default handling due to performance issues. I'm trying to get a full MVP out first, so this just recognizes GPU functions based on magic names. The final frontend will obviously move this over to use proper macros, like I'm already doing it for the autodiff work. This work will also be compatible with std::autodiff, so one can differentiate GPU kernels. Tracking: - https://github.com/rust-lang/rust/issues/131513

2025-07-20Auto merge of #143002 - Enselic:tests-ui-run-fail-exit-vs-signal, r=petrochenkovbors-7/+19
tests: Require `run-fail` ui tests to have an exit code (`SIGABRT` not ok) And introduce two new directives for ui tests: * `run-crash` * `run-fail-or-crash` Normally a `run-fail` ui test like tests that panic shall not be terminated by a signal like `SIGABRT`. So begin having that as a hard requirement. Some of our current tests do terminate by a signal/crash however. Introduce and use `run-crash` for those tests. Note that Windows crashes are not handled by signals but by certain high bits set on the process exit code. Example exit code for crash on Windows: `0xc000001d` (`STATUS_ILLEGAL_INSTRUCTION`). Because of this, we define "crash" on all platforms as "not exit with success and not exit with a regular failure code in the range 1..=127". Some tests behave differently on different targets: * Targets without unwind support will abort (crash) instead of exit with failure code 101 after panicking. As a special case, allow crashes for `run-fail` tests for such targets. * Different sanitizer implementations handle detected memory problems differently. Some abort (crash) the process while others exit with failure code 1. Introduce and use `run-fail-or-crash` for such tests. This adds further (cc https://github.com/rust-lang/rust/pull/142304, https://github.com/rust-lang/rust/pull/142886) protection against the regression in https://github.com/rust-lang/rust/issues/123733 since that bug also manifested as `SIGABRT` in `tests/ui/panics/panic-main.rs` (shown as `Aborted (core dumped)` in the logs attached to that issue, and I have also been able to reproduce this locally). ### TODO - [x] **Q:** what about on Windows? **A:** we'll treat any exit code outside of 1 - 127 as "crashed", and we'll do the same on unix. - [x] test all permutations of actual vs expected **Done:** See https://github.com/rust-lang/rust/pull/143002#issuecomment-3007502894. - [x] Handle targets without unwind support - [x] Add `run-fail-or-crash` for some sanitizer tests - [x] remote-test-client.
