2023-04-22Auto merge of #109507 - Amanieu:panic-oom-payload, r=davidtwcobors-2/+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.

2023-04-19Auto merge of #110407 - Nilstrieb:fluent-macro, r=davidtwcobors-1/+1
Add `rustc_fluent_macro` to decouple fluent from `rustc_macros` Fluent, with all the icu4x it brings in, takes quite some time to compile. `fluent_messages!` is only needed in further downstream rustc crates, but is blocking more upstream crates like `rustc_index`. By splitting it out, we allow `rustc_macros` to be compiled earlier, which speeds up `x check compiler` by about 5 seconds (and even more after the needless dependency on `serde_json` is removed from `rustc_data_structures`).

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-1/+4
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.

2022-10-31Rewrite implementation of `#[alloc_error_handler]`Amanieu d'Antras-2/+2
The new implementation doesn't use weak lang items and instead changes `#[alloc_error_handler]` to an attribute macro just like `#[global_allocator]`. The attribute will generate the `__rg_oom` function which is called by the compiler-generated `__rust_alloc_error_handler`. If no `__rg_oom` function is defined in any crate then the compiler shim will call `__rdl_oom` in the alloc crate which will simply panic. This also fixes link errors with `-C link-dead-code` with `default_alloc_error_handler`: `__rg_oom` was previously defined in the alloc crate and would attempt to reference the `oom` lang item, even if it didn't exist. This worked as long as `__rg_oom` was excluded from linking since it was not called. This is a prerequisite for the stabilization of `default_alloc_error_handler` (#102318).

2022-02-21debuginfo: Simplify TypeMap used during LLVM debuginfo generation.Michael Woerister-0/+4
The previous implementation was written before types were properly normalized for code generation and had to assume a more complicated relationship between types and their debuginfo -- generating separate identifiers for debuginfo nodes that were based on normalized types. Since types are now already normalized, we can use them as identifiers for debuginfo nodes.

2021-12-15Rollup merge of #91881 - Patrick-Poitras:stabilize-iter-zip, r=scottmcmMatthias Krüger-1/+0
Stabilize `iter::zip` Hello all! As the tracking issue (#83574) for `iter::zip` completed the final commenting period without any concerns being raised, I hereby submit this stabilization PR on the issue. As the pull request that introduced the feature (#82917) states, the `iter::zip` function is a shorter way to zip two iterators. As it's generally a quality-of-life/ergonomic improvement, it has been integrated into the codebase without any trouble, and has been used in many places across the rust compiler and standard library since March without any issues. For more details, I would refer to `@cuviper's` original PR, or the [function's documentation](https://doc.rust-lang.org/std/iter/fn.zip.html).

Use `OutputFilenames` to generate output file for `-Zllvm-time-trace` The resulting profile will include the crate name and will be stored in the `--out-dir` directory. This implementation makes it convenient to use LLVM time trace together with cargo, in the contrast to the previous implementation which would overwrite profiles or store them in `.cargo/registry/..`.

2021-12-07Use object crate for .rustc metadata generationNikita Popov-8/+0
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.
