Revert "Remove macOS fat archive support from LlvmArchiveBuilder"

2023-02-02T20:22:04+00:00

This reverts commit 047c7cc60c05e2cf182c6f578581cf2a67b1d0ff.

Revert back to LlvmArchiveBuilder on all platforms

2023-02-02T20:21:35+00:00

ArArchiveBuilder doesn't support reading thin archives, causing a regression.

Use UnordSet instead of FxHashSet in define_id_collections!().

Various cleanups around pre-TyCtxt queries and functions part of #105462 based on https://github.com/rust-lang/rust/pull/106776 (everything starting at [0e2b39f](https://github.com/rust-lang/rust/pull/106810/commits/0e2b39fd1ffde51b50d45ccbe41de52b85136b8b) is new in this PR) r? `@petrochenkov` I think this should be most of the uncontroversial part of #105462.

Put `noundef` on all scalars that don't allow uninit

2023-01-17T07:14:35+00:00

Previously, it was only put on scalars with range validity invariants like bool, was uninit was obviously invalid for those. Since then, we have normatively declared all uninit primitives to be undefined behavior and can therefore put `noundef` on them. The remaining concern was the `mem::uninitialized` function, which cause quite a lot of UB in the older parts of the ecosystem. This function now doesn't return uninit values anymore, making users of it safe from this change. The only real sources of UB where people could encounter uninit primitives are `MaybeUninit::uninit().assume_init()`, which has always be clear in the docs about being UB and from heap allocations (like reading from the spare capacity of a vec. This is hopefully rare enough to not break anything.

Rollup merge of #104543 - JhonnyBillM:migrate-codegen-ssa-to-diagnostics-structs-pt3, r=davidtwco

2023-01-07T19:43:19+00:00

Migrate `codegen_ssa` to diagnostics structs - [Part 3] Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates: 1. [`rustc_middle::mir::interpret::InterpError`](https://github.com/rust-lang/rust/blob/b6097f2e1b2ca62e188ba53cf43bd66b06b36915/compiler/rustc_middle/src/mir/interpret/error.rs#L475): I saw `rustc_middle` is unassigned, I am open to take this work. 2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](https://github.com/rust-lang/rust/commit/9a31b3cdda78a2c0891828254fe9886e0a1cfd16) of this PR, but would like to know the team's preference on how we should keep replacing the other macros: 2.1. Update macros to expect a `Diagnostic` 2.2. Remove macros and expand the code on each use. See [some examples of the different options in this experimental commit](https://github.com/JhonnyBillM/rust/commit/64aee83e80857dcfa450f0c6e31d5f29c6d577e6) _Part 2 - https://github.com/rust-lang/rust/pull/103792_ r? ``@davidtwco`` Cc ``@compiler-errors``
