2024-04-23Auto merge of #3493 - eduardosm:env-set, r=oli-obkbors-12/+43
Add `-Zmiri-env-set` to set environment variables without modifying the host environment This option allows to pass environment variables to the interpreted program without needing to modify the host environment (which may have undesired effects in some cases).

2024-04-23Auto merge of #121801 - zetanumbers:async_drop_glue, r=oli-obkbors-24/+1916
Add simple async drop glue generation This is a prototype of the async drop glue generation for some simple types. Async drop glue is intended to behave very similar to the regular drop glue except for being asynchronous. Currently it does not execute synchronous drops but only calls user implementations of `AsyncDrop::async_drop` associative function and awaits the returned future. It is not complete as it only recurses into arrays, slices, tuples, and structs and does not have same sensible restrictions as the old `Drop` trait implementation like having the same bounds as the type definition, while code assumes their existence (requires a future work). This current design uses a workaround as it does not create any custom async destructor state machine types for ADTs, but instead uses types defined in the std library called future combinators (deferred_async_drop, chain, ready_unit). Also I recommend reading my [explainer](https://zetanumbers.github.io/book/async-drop-design.html). This is a part of the [MCP: Low level components for async drop](https://github.com/rust-lang/compiler-team/issues/727) work. Feature completeness: - [x] `AsyncDrop` trait - [ ] `async_drop_in_place_raw`/async drop glue generation support for - [x] Trivially destructible types (integers, bools, floats, string slices, pointers, references, etc.) - [x] Arrays and slices (array pointer is unsized into slice pointer) - [x] ADTs (enums, structs, unions) - [x] tuple-like types (tuples, closures) - [ ] Dynamic types (`dyn Trait`, see explainer's [proposed design](https://github.com/zetanumbers/posts/blob/main/async-drop-design.md#async-drop-glue-for-dyn-trait)) - [ ] coroutines (https://github.com/rust-lang/rust/pull/123948) - [x] Async drop glue includes sync drop glue code - [x] Cleanup branch generation for `async_drop_in_place_raw` - [ ] Union rejects non-trivially async destructible fields - [ ] `AsyncDrop` implementation requires same bounds as type definition - [ ] Skip trivially destructible fields (optimization) - [ ] New [`TyKind::AdtAsyncDestructor`](https://github.com/zetanumbers/posts/blob/main/async-drop-design.md#adt-async-destructor-types) and get rid of combinators - [ ] [Synchronously undroppable types](https://github.com/zetanumbers/posts/blob/main/async-drop-design.md#exclusively-async-drop) - [ ] Automatic async drop at the end of the scope in async context

miri libstd tests: test windows-msvc instead of windows-gnu This avoids https://github.com/rust-lang/rust/issues/123583. MSVC is the more widely used target anyway AFAIK, so probably makes more sense to cover that.

coverage: Prepare for improved branch coverage When trying to rebase my new branch coverage work (including #124154) on top of the introduction of MC/DC coverage (#123409), I found it a lot harder than anticipated. With the benefit of hindsight, the branch coverage code and MC/DC code have become more interdependent than I'm happy with. This PR therefore disentangles them a bit, so that it will be easier for both areas of code to evolve independently without interference. --- This PR also includes a few extra branch coverage tests that I had sitting around from my current branch coverage work. They mostly just demonstrate that certain language constructs listed in #124118 currently don't have branch coverage support. ``@rustbot`` label +A-code-coverage

2024-04-22Auto merge of #115120 - icedrocket:ignore-strip-on-msvc, r=michaelwoeristerbors-57/+103
Ignore `-C strip` on MSVC tl;dr - Define `-Cstrip` to only ever affect the binary; no other build artifacts. This is necessary to improve cross-platform behavior consistency: if someone wanted debug information to be contained only in separate files on all platforms, they would set `-Cstrip=symbols` and `-Csplit-debuginfo=packed`, but this would result in no PDB files on MSVC. Resolves #114215

Add localtime_r shim - Implement ``localtime_r`` shim as mentioned in #2057 Note: - ``tm_zone``, ``tm_gmtoff`` might not be consistent with ``libc::localtime_r`` as custom implementation is provided through ``chrono``.
