2023-10-22coverage: Encode function mappings without re-sorting themZalathar-1/+1
The main change here is that `VirtualFileMapping` now uses an internal hashmap to de-duplicate incoming global file IDs. That removes the need for `encode_mappings_for_function` to re-sort its mappings by filename in order to de-duplicate them. (We still de-duplicate runs of identical filenames to save work, but this is not load-bearing for correctness, so a sort is not necessary.)

c6e6ecb1afea9695a42d0f148ce153536b279eb5 added it to some of the compiler's crates, but avoided adding it to all of them to reduce bit-rot. This commit adds to more.

2023-07-21Rollup merge of #113780 - dtolnay:printkindpath, r=b-naberMatthias Krüger-18/+19
Support `--print KIND=PATH` command line syntax As is already done for `--emit KIND=PATH` and `-L KIND=PATH`. In the discussion of #110785, it was pointed out that `--print KIND=PATH` is nicer than trying to apply the single global `-o` path to `--print`'s output, because in general there can be multiple print requests within a single rustc invocation, and anyway `-o` would already be used for a different meaning in the case of `link-args` and `native-static-libs`. I am interested in using `--print cfg=PATH` in Buck2. Currently Buck2 works around the lack of support for `--print KIND=PATH` by [indirecting through a Python wrapper script](https://github.com/facebook/buck2/blob/d43cf3a51a31f00be2c2248e78271b0fef0452b4/prelude/rust/tools/get_rustc_cfg.py) to redirect rustc's stdout into the location dictated by the build system. From skimming Cargo's usages of `--print`, it definitely seems like it would benefit from `--print KIND=PATH` too. Currently it is working around the lack of this by inserting `--crate-name=___ --print=crate-name` so that it can look for a line containing `___` as a delimiter between the 2 other `--print` informations it actually cares about. This is commented as a "HACK" and "abuse". https://github.com/rust-lang/cargo/blob/31eda6f7c360d9911f853b3014e057db61238f3e/src/cargo/core/compiler/build_context/target_info.rs#L242 (FYI `@weihanglo` as you dealt with this recently in https://github.com/rust-lang/cargo/pull/11633.)

2023-07-16rustc_llvm: Add a `-Z print-llvm-stats` option to expose LLVM statistics.Patrick Walton-0/+5
LLVM has a neat [statistics] feature that tracks how often optimizations kick in. It's very handy for optimization work. Since we expose the LLVM pass timings, I thought it made sense to expose the LLVM statistics too. [statistics]: https://llvm.org/docs/ProgrammersManual.html#the-statistic-class-stats-option

Rather than returning an array of features from to_llvm_features, return a structure that contains the dependencies. This also contains metadata on how the features depend on each other to allow for the correct enabling and disabling.

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`).

2023-02-22errors: generate typed identifiers in each crateDavid Wood-1/+4

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).
