Seems this doesn't trigger error on LLVM 15, but let's fix it for better compatibility.

2022-08-28Support `#[unix_sigpipe = "inherit|sig_dfl|sig_ign"]` on `fn main()`Martin Nordholts-6/+10
This makes it possible to instruct libstd to never touch the signal handler for `SIGPIPE`, which makes programs pipeable by default (e.g. with `./your-program | head -n 1`) without `ErrorKind::BrokenPipe` errors.

2022-07-27Reliably signal coordinator thread on panic during ongoing codegenNikita Popov-54/+4
Replace the separate AbortCodegenOnDrop guard by integrating this functionality into OngoingCodegen (or rather, the Coordinator part of it). This ensures that we send a CodegenAborted message and wait for workers to finish even if the panic occurs outside codegen_crate() (e.g. inside join_codegen()). This requires some minor changes to the handling of CodegenAborted, as it can now occur when the main thread is LLVMing rather than Codegenning.

2022-07-13Rename `debugging_opts` to `unstable_opts`Joshua Nelson-1/+1
This is no longer used only for debugging options (e.g. `-Zoutput-width`, `-Zallow-features`). Rename it to be more clear.

It returns the previous work product or panics if there is none. This rename makes the purpose of this method clearer.

There is no reason it needs to be lazily computed at the first iteration of the cgu loop.

Generate synthetic object file to ensure all exported and used symbols participate in the linking Fix #50007 and #47384 This is the synthetic object file approach that I described in https://github.com/rust-lang/rust/pull/95363#issuecomment-1079932354, allowing all exported and used symbols to be linked while still allowing them to be GCed.

Remove `SymbolStr` This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences. Best reviewed one commit at a time. r? `@oli-obk`

2021-12-07Use object crate for .rustc metadata generationNikita Popov-26/+40
We already use the object crate for generating uncompressed .rmeta metadata object files. This switches the generation of compressed .rustc object files to use the object crate as well. These have slightly different requirements in that .rmeta should be completely excluded from any final compilation artifacts, while .rustc should be part of shared objects, but not loaded into memory. The primary motivation for this change is #90326: In LLVM 14, the current way of setting section flags (and in particular, preventing the setting of SHF_ALLOC) will no longer work. There are other ways we could work around this, but switching to the object crate seems like the most elegant, as we already use it for .rmeta, and as it makes this independent of the codegen backend. In particular, we don't need separate handling in codegen_llvm and codegen_gcc. codegen_cranelift should be able to reuse the implementation as well, though I have omitted that here, as it is not based on codegen_ssa. This change mostly extracts the existing code for .rmeta handling to allow using it for .rustc as well, and adjust the codegen infrastructure to handle the metadata object file separately: We no longer create a backend-specific module for it, and directly produce the compiled module instead. This does not fix #90326 by itself yet, as .llvmbc will need to be handled separately.
2021-09-30Move EncodedMetadata to rustc_metadata.Camille GILLOT-1/+1
2021-09-05Auto merge of #88499 - eddyb:layout-off, r=nagisabors-2/+2
Provide `layout_of` automatically (given tcx + param_env + error handling). After #88337, there's no longer any uses of `LayoutOf` within `rustc_target` itself, so I realized I could move the trait to `rustc_middle::ty::layout` and redesign it a bit. This is similar to #88338 (and supersedes it), but at no ergonomic loss, since there's no funky `C: LayoutOf<Ty = Ty>` -> `Ty: TyAbiInterface<C>` generic `impl` chain, and each `LayoutOf` still corresponds to one `impl` (of `LayoutOfHelpers`) for the specific context. After this PR, this is what's needed to get `trait LayoutOf` (with the `layout_of` method) implemented on some context type: * `TyCtxt`, via `HasTyCtxt` * `ParamEnv`, via `HasParamEnv` * a way to transform `LayoutError`s into the desired error type * an error type of `!` can be paired with having `cx.layout_of(...)` return `TyAndLayout` *without* `Result<...>` around it, such as used by codegen * this is done through a new `LayoutOfHelpers` trait (and so is specifying the type of `cx.layout_of(...)`) When going through this path (and not bypassing it with a manual `impl` of `LayoutOf`), the end result is that only the error case can be customized, the query itself and the success paths are guaranteed to be uniform. (**EDIT**: just noticed that because of the supertrait relationship, you cannot actually implement `LayoutOf` yourself, the blanket `impl` fully covers all possible context types that could ever implement it) Part of the motivation for this shape of API is that I've been working on querifying `FnAbi::of_*`, and what I want/need to introduce for that looks a lot like the setup in this PR - in particular, it's harder to express the `FnAbi` methods in `rustc_target`, since they're much more tied to `rustc` concepts. r? `@nagisa` cc `@oli-obk` `@bjorn3`

2021-08-31Include debug info for the allocator shimDaniel Paoliello-3/+9
Issue Details: In some cases it is necessary to generate an "allocator shim" to forward various Rust allocation functions (e.g., `__rust_alloc`) to an underlying function (e.g., `malloc`). However, since this allocator shim is a manually created LLVM module it is not processed via the normal module processing code and so no debug info is generated for it (if debugging info is enabled). Fix Details: * Modify the `debuginfo` code to allow creating debug info for a module without a `CodegenCx` (since it is difficult, and expensive, to create one just to emit some debug info). * After creating the allocator shim add in basic debug info.
