2023-05-19Auto merge of #111641 - michaelwoerister:debugger-visualizer-fixes, r=cjgillotbors-1/+1
Fix dependency tracking for debugger visualizers This PR fixes dependency tracking for debugger visualizer files by changing the `debugger_visualizers` query to an `eval_always` query that scans the AST while it is still available. This way the set of visualizer files is already available when dep-info is emitted. Since the query is turned into an `eval_always` query, dependency tracking will now reliably detect changes to the visualizer script files themselves.

2023-05-10Auto merge of #106560 - bjorn3:support_staticlib_dylib_linking, r=pnkfelixbors-5/+70
Support linking to rust dylib with --crate-type staticlib This allows for example dynamically linking libstd, while statically linking the user crate into an executable or C dynamic library. For this two unstable flags (`-Z staticlib-allow-rdylib-deps` and `-Z staticlib-prefer-dynamic`) are introduced. Without the former you get an error. The latter is the equivalent to `-C prefer-dynamic` for the staticlib crate type to indicate that dynamically linking is preferred when both options are available, like for libstd. Care must be taken to ensure that no crate ends up being merged into two distinct staticlibs that are linked together. Doing so will cause a linker error at best and undefined behavior at worst. In addition two distinct staticlibs compiled by different rustc may not be combined under any circumstances due to some rustc private symbols not being mangled. To successfully link a staticlib, `--print native-static-libs` can be used while compiling to ask rustc for the linker flags necessary when linking the staticlib. This is an existing flag which previously only listed native libraries. It has been extended to list rust dylibs too. Trying to locate libstd yourself to link against it is not supported and may break if for example the libstd of multiple rustc versions are put in the same directory. For an example on how to use this see the `src/test/run-make-fulldeps/staticlib-dylib-linkage/` test.

2023-05-03Restrict `From<S>` for `{D,Subd}iagnosticMessage`.Nicholas Nethercote-4/+4
Currently a `{D,Subd}iagnosticMessage` can be created from any type that impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static, str>`, which are reasonable. It also includes `&String`, which is pretty weird, and results in many places making unnecessary allocations for patterns like this: ``` self.fatal(&format!(...)) ``` This creates a string with `format!`, takes a reference, passes the reference to `fatal`, which does an `into()`, which clones the reference, doing a second allocation. Two allocations for a single string, bleh. This commit changes the `From` impls so that you can only create a `{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static, str>`. This requires changing all the places that currently create one from a `&String`. Most of these are of the `&format!(...)` form described above; each one removes an unnecessary static `&`, plus an allocation when executed. There are also a few places where the existing use of `&String` was more reasonable; these now just use `clone()` at the call site. As well as making the code nicer and more efficient, this is a step towards possibly using `Cow<'static, str>` in `{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing the `From<&'a str>` impls to `From<&'static str>`, which is doable, but I'm not yet sure if it's worthwhile.

Fixes https://github.com/rust-lang/rust/issues/110912 Checking `flavor == RlibFlavor::Normal` was accidentally lost in 601fc8b36b1962285e371cf3c54eeb3b1b9b3a74 https://github.com/rust-lang/rust/pull/105601 That caused combining +whole-archive and +bundle link modifiers on non-rlib crates to fail with a confusing error message saying that combination is unstable for rlibs. In particular, this caused the build to fail when +whole-archive was used on staticlib crates, even though +whole-archive effectively does nothing on non-bin crates because the final linker invocation is left to an external build system.

2023-04-22Auto merge of #109507 - Amanieu:panic-oom-payload, r=davidtwcobors-1/+1
Report allocation errors as panics OOM is now reported as a panic but with a custom payload type (`AllocErrorPanicPayload`) which holds the layout that was passed to `handle_alloc_error`. This should be review one commit at a time: - The first commit adds `AllocErrorPanicPayload` and changes allocation errors to always be reported as panics. - The second commit removes `#[alloc_error_handler]` and the `alloc_error_hook` API.

Initial support for loongarch64-unknown-linux-gnu Hi, We hope to add a new port in rust for LoongArch. LoongArch intro LoongArch is a RISC style ISA which is independently designed by Loongson Technology in China. It is divided into two versions, the 32-bit version (LA32) and the 64-bit version (LA64). LA64 applications have application-level backward binary compatibility with LA32 applications. LoongArch is composed of a basic part (Loongson Base) and an expanded part. The expansion part includes Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD EXtension (LSX) and Loongson Advanced SIMD EXtension(LASX). Currently the LA464 processor core supports LoongArch ISA and the Loongson 3A5000 processor integrates 4 64-bit LA464 cores. LA464 is a four-issue 64-bit high-performance processor core. It can be used as a single core for high-end embedded and desktop applications, or as a basic processor core to form an on-chip multi-core system for server and high-performance machine applications. Documentations: ISA: https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html ABI: https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html More docs can be found at: https://loongson.github.io/LoongArch-Documentation/README-EN.html Since last year, we have locally adapted two versions of rust, rust1.41 and rust1.57, and completed the test locally. I'm not sure if I'm submitting all the patches at once, so I split up the patches and here's one of the commits

`-Cdebuginfo=1` was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for line tables only was added. Additionally an option for line info directives only was added, which is well needed for some targets. The debug info options should now behave the same as clang's debug info options.
2023-03-29Auto merge of #108089 - Zoxc:windows-tls, r=bjorn3bors-7/+36
Support TLS access into dylibs on Windows This allows access to `#[thread_local]` in upstream dylibs on Windows by introducing a MIR shim to return the address of the thread local. Accesses that go into an upstream dylib will call the MIR shim to get the address of it. `convert_tls_rvalues` is introduced in `rustc_codegen_ssa` which rewrites MIR TLS accesses to dummy calls which are replaced with calls to the MIR shims when the dummy calls are lowered to backend calls. A new `dll_tls_export` target option enables this behavior with a `false` value which is set for Windows platforms. This fixes https://github.com/rust-lang/rust/issues/84933.
