2023-02-22various: translation resources from cg backendDavid Wood-0/+4
Extend `CodegenBackend` trait with a function returning the translation resources from the codegen backend, which can be added to the complete list of resources provided to the emitter. Signed-off-by: David Wood <david.wood@huawei.com>
2023-02-22errors: generate typed identifiers in each crateDavid Wood-4/+97
Instead of loading the Fluent resources for every crate in `rustc_error_messages`, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the `rustc_driver` crate and provided to the diagnostic emitter.

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.

Specify dlltool prefix when generating import libs Ref: https://github.com/rust-lang/rust/pull/106610#issuecomment-1418221274 tl;dr: This PR adds an explicit dlltool temporary filename prefix. The prefix resolves a race condition by ensuring dlltool temporary files are siloed in an appropriate/unique Rust temporary directory. --- GNU dlltool, as part of its import library generation logic, uses a bunch of temporary files on disk. In the interest of deterministic build runs, dlltool supports deterministic temporary filenames. The temporary filename prefix is automatically generated internally or can be explicitly specified via a `--temp-prefix` argument. GNU dlltool **2.38** (that ships with `x86_64-12.2.0-release-posix-seh-rt_v10-rev0` [installed during CI](https://github.com/rust-lang/rust/blob/master/src/ci/scripts/install-mingw.sh)) generates a prefix based on the target library name ([source](https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=binutils/dlltool.c;h=d95bf3f5470b999fa3b30bc887791859f48d81d1;hb=20756b0fbe065a84710aa38f2457563b57546440#l3992)). The tool writes to files such as `target_dll_h.s` and `target_dll_s00203.o` in the current working directory. This presents a problem when multiple instances of rustc_codegen_llvm are running to generate an import library (as part of the raw_dylib feature) for the same target library (e.g. kernel32) ([source](https://github.com/rust-lang/rust/blob/master/compiler/rustc_codegen_llvm/src/back/archive.rs#L185-L196)). That is, dlltool instances race and may overwrite or delete files belonging to each other. GNU dlltool **2.39**+ (not used in Rust CI) generates a prefix based on the output library path ([source](https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=binutils/dlltool.c;h=e2af20847009945b4c61a6fef08268fbb4429715;hb=b51c2fec1da205ea3e7354cbb3e253018d64873c#l3992)). The tool, when invoked as part of rustc_codegen_llvm, writes to files at paths such as `C_Users_Foo_AppData_Local_Temp_rustcOFqhXZ_target_lib_h.s`. (The output library path is normalized and non-alphanumeric characters are replaced with underscores.)
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.

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.

...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.
