Instead of manually navigating directories based on stage0 rustc, use `--print sysroot` to get the sysroot directly. This also works when using the bootstrap `rustc` shim. Signed-off-by: onur-ozkan <[email protected]>
It looks like this was added 6 years ago because of issues with the MacOS linker. MacOS got a new linker in the meantime, so that should probably be resolved now. Hopefully.
Structurally normalize types as needed in `projection_ty_core` Introduce a `structurally_normalize` callback to `projection_ty_core`, and then use it before we match on the ty kind in `projection_ty_core`. Previously we were only structurally normalizing the return type of the `handle_field` struct, but if we were to (e.g.) apply a deref projection to that type, then the resulting type is not guaranteed to be structurally normalized and any subsequent projections applied would ICE. Fixes rust-lang/trait-system-refactor-initiative#221 I'll leave a few comments inline to explain the changes. r? lcnr --- Also fixes rust-lang#141708
Add tls_model for cygwin and enable has_thread_local I've also tried to set `has_thread_local` to `true` and found it works actually. Why do we still implement our own `thread_local` instead of delegating all of them to LLVM? cc: `@jeremyd2019`
…rom-rustc, r=Kobzol resolve stage0 sysroot from rustc Similar to rust-lang#141729, instead of manually navigating directories based on stage0 rustc, use `--print sysroot` to get the sysroot directly. This also works when using the bootstrap `rustc` shim. r? Kobzol
…llaumeGomez Rework `#[doc(cfg(..))]` checks as distinct pass in rustdoc This PR reworks how rustdoc calls `rustc_attr_parsing::cfg_matches` to be in a separate pass, instead of being wired-up in a ad-hoc way, which is causing problems in rust-lang#138907 (comment). This un-does most part of rust-lang#140894, but the result is IMO much cleaner, easier to reason about, and most importantly no longer interfears with rust-lang#138907. r? `@GuillaumeGomez`
…TRY_LINKER_ON_SEGFAULT, r=petrochenkov Remove RUSTC_RETRY_LINKER_ON_SEGFAULT hack It looks like this was added in rust-lang#40422 6 years ago because of issues with the MacOS linker. MacOS got a new linker in the meantime, so that should probably be resolved now. Hopefully. r? petrochenkov

Finished benchmarking commit (aa5832b): comparison URL. Overall result: ❌✅ regressions and improvements - please read the text belowOur benchmarks found a performance regression caused by this PR. Next Steps:
@rustbot label: +perf-regression Instruction countThis is the most reliable metric that we have; it was used to determine the overall result at the top of this comment. However, even this metric can sometimes exhibit noise.
Max RSS (memory usage)Results (primary -0.1%, secondary -0.7%)This is a less reliable metric that may be of interest but was not used to determine the overall result at the top of this comment.
CyclesResults (secondary 0.2%)This is a less reliable metric that may be of interest but was not used to determine the overall result at the top of this comment.
Binary sizeThis benchmark run did not return any relevant results for this metric. Bootstrap: missing data |

No clear cause (inlining changes?) from one cachegrind run. I don't think there's further investigation warranted. |
