2023-02-18Auto merge of #99679 - repnop:kernel-address-sanitizer, r=cuviperbors-1/+7
Add `kernel-address` sanitizer support for freestanding targets This PR adds support for KASan (kernel address sanitizer) instrumentation in freestanding targets. I included the minimal set of `x86_64-unknown-none`, `riscv64{imac, gc}-unknown-none-elf`, and `aarch64-unknown-none` but there's likely other targets it can be added to. (`linux_kernel_base.rs`?) KASan uses the address sanitizer attributes but has the `CompileKernel` parameter set to `true` in the pass creation.

Add `-Z instrument-xray` flag Implement MCP https://github.com/rust-lang/compiler-team/issues/561, adding `-Z instrument-xray` flag which enables XRay instrumentation in LLVM.
2023-02-09Emit basic XRay instrumentation attributesOleksii Lozovskyi-0/+28
Add the attributes to functions according to the settings. "xray-always" overrides "xray-never", and they both override "xray-ignore-loops" and "xray-instruction-threshold", but we'll let lints deal with warnings about silly attribute combinations.

Four because that's the new reasonable maximum for XRay instrumentation attributes in the following commit.

2023-01-28Rollup merge of #107373 - ↵Matthias Krüger-0/+5
michaelwoerister:dont-merge-vtables-when-debuginfo, r=WaffleLapkin Don't merge vtables when full debuginfo is enabled. This PR makes the compiler not emit the `unnamed_addr` attribute for vtables when full debuginfo is enabled, so that they don't get merged even if they have the same contents. This allows debuggers to more reliably map from a dyn pointer to the self-type of a trait object by looking at the vtable's debuginfo. The PR only changes the behavior of the LLVM backend as other backends don't emit vtable debuginfo (as far as I can tell). The performance impact of this change should be small as [measured](https://github.com/rust-lang/rust/pull/103514#issuecomment-1290833854) in a previous PR.

Remove backwards compat for LLVM 12 coverage format The minimum external LLVM was updated to 13 recently in https://github.com/rust-lang/rust/pull/100611, so this PR removes backwards compat with older coverage formats. I kept the version check and error message there, in accordance with this comment: https://github.com/rust-lang/rust/pull/91207#issuecomment-981121867

2023-01-22abi: add `AddressSpace` field to `Primitive::Pointer`Erik Desjardins-18/+23
...and remove it from `PointeeInfo`, which isn't meant for this. There are still various places (marked with FIXMEs) that assume all pointers have the same size and alignment. Fixing this requires parsing non-default address spaces in the data layout string, which will be done in a followup.

2023-01-17Put `noundef` on all scalars that don't allow uninitNilstrieb-1/+1
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.

JhonnyBillM:migrate-codegen-ssa-to-diagnostics-structs-pt3, r=davidtwco 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``
