For example, a direct comparaison of two raw pointers will not trigger the lint anymore. --- clippy_lints/src/ptr.rs | 22 ++++++++++++-------- tests/ui/ptr_eq.fixed | 26 +++++++++++++----------- tests/ui/ptr_eq.rs | 16 ++++++++------- tests/ui/ptr_eq.stderr | 38 ++++------------------------------- tests/ui/ptr_eq_no_std.fixed | 20 +++++++++--------- tests/ui/ptr_eq_no_std.rs | 12 ++++++----- tests/ui/ptr_eq_no_std.stderr | 26 +----------------------- 7 files changed, 60 insertions(+), 100 deletions(-) diff --git a/clippy_lints/src/ptr.rs b/clippy_lints/src/ptr.rs index 5fb4d3a837b1..b76e54c382db 100644 --- a/clippy_lints/src/ptr.rs +++ b/clippy_lints/src/ptr.rs @@ -715,9 +715,9 @@ fn check_ptr_eq<'tcx>( } // Remove one level of usize conversion if any - let (left, right) = match (expr_as_cast_to_usize(cx, left), expr_as_cast_to_usize(cx, right)) { - (Some(lhs), Some(rhs)) => (lhs, rhs), - _ => (left, right), + let (left, right, usize_peeled) = match (expr_as_cast_to_usize(cx, left), expr_as_cast_to_usize(cx, right)) { + (Some(lhs), Some(rhs)) => (lhs, rhs, true), + _ => (left, right, false), };

The unfortunate thing about this is that the analysis needs to be mutable everywhere (`&mut Analysis`) which forces the `Results` to be mutable everywhere, even though `EntryStates` is immutable everywhere. To fix this, this commit renames `Results` as `AnalysisAndResults`, renames `EntryStates` as `Results`, and separates the analysis and results as much as possible. (`AnalysisAndResults` doesn't get much use, it's mostly there to facilitate method chaining of `iterate_to_fixpoint`.) `Results` is immutable everywhere, which: - is a bit clearer on how the data is used, - avoids an unnecessary clone of entry states in `locals_live_across_suspend_points`, and - moves the results outside the `RefCell` in Formatter. The commit also reformulates `ResultsHandle` as the generic `CowMut`, which is simpler than `ResultsHandle` because it doesn't need the `'tcx` lifetime and the trait bounds. It also which sits nicely alongside the new use of `Cow` in `ResultsCursor`. --- compiler/rustc_borrowck/src/lib.rs | 20 ++--- .../src/framework/cursor.rs | 78 +++++++++++-------- .../src/framework/direction.rs | 18 ++--- .../src/framework/graphviz.rs | 32 ++++---- .../rustc_mir_dataflow/src/framework/mod.rs | 30 ++++--- .../src/framework/results.rs | 57 +++----------- .../rustc_mir_dataflow/src/framework/tests.rs | 6 +- .../src/framework/visitor.rs | 23 +++++- compiler/rustc_mir_dataflow/src/lib.rs | 4 +- compiler/rustc_mir_dataflow/src/points.rs | 6 +- compiler/rustc_mir_dataflow/src/rustc_peek.rs | 20 ++--- compiler/rustc_mir_transform/src/coroutine.rs | 47 +++++++---- .../src/dataflow_const_prop.rs | 11 +-- compiler/rustc_mir_transform/src/dest_prop.rs | 2 +- .../src/lint_tail_expr_drop_order.rs | 5 +- src/doc/rustc-dev-guide/src/mir/dataflow.md | 3 +- 16 files changed, 188 insertions(+), 174 deletions(-) diff --git a/compiler/rustc_borrowck/src/lib.rs b/compiler/rustc_borrowck/src/lib.rs index 4ba238696e29..bf6512ee2332 100644 --- a/compiler/rustc_borrowck/src/lib.rs +++ b/compiler/rustc_borrowck/src/lib.rs @@ -47,7 +47,7 @@ use rustc_mir_dataflow::impls::{ use rustc_mir_dataflow::move_paths::{ InitIndex, InitLocation, LookupResult, MoveData, MovePathIndex, }; -use rustc_mir_dataflow::{Analysis, EntryStates, Results, ResultsVisitor, visit_results}; +use rustc_mir_dataflow::{Analysis, Results, ResultsVisitor, visit_results}; use rustc_session::lint::builtin::{TAIL_EXPR_DROP_ORDER, UNUSED_MUT}; use rustc_span::{ErrorGuaranteed, Span, Symbol}; use smallvec::SmallVec; @@ -461,11 +461,13 @@ fn do_mir_borrowck<'tcx>( // Compute and report region errors, if any. mbcx.report_region_errors(nll_errors); - let mut flow_results = get_flow_results(tcx, body, &move_data, &borrow_set, ®ioncx); + let (mut flow_analysis, flow_entry_states) = + get_flow_results(tcx, body, &move_data, &borrow_set, ®ioncx); visit_results( body, traversal::reverse_postorder(body).map(|(bb, _)| bb), - &mut flow_results, + &mut flow_analysis, + &flow_entry_states, &mut mbcx, ); @@ -525,7 +527,7 @@ fn get_flow_results<'a, 'tcx>( move_data: &'a MoveData<'tcx>, borrow_set: &'a BorrowSet<'tcx>, regioncx: &RegionInferenceContext<'tcx>, -) -> Results<'tcx, Borrowck<'a, 'tcx>> { +) -> (Borrowck<'a, 'tcx>, Results) { // We compute these three analyses individually, but them combine them into // a single results so that `mbcx` can visit them all together. let borrows = Borrows::new(tcx, body, regioncx, borrow_set).iterate_to_fixpoint( @@ -550,14 +552,14 @@ fn get_flow_results<'a, 'tcx>( ever_inits: ever_inits.analysis, }; - assert_eq!(borrows.entry_states.len(), uninits.entry_states.len()); - assert_eq!(borrows.entry_states.len(), ever_inits.entry_states.len()); - let entry_states: EntryStates<'_, Borrowck<'_, '_>> = - itertools::izip!(borrows.entry_states, uninits.entry_states, ever_inits.entry_states) + assert_eq!(borrows.results.len(), uninits.results.len()); + assert_eq!(borrows.results.len(), ever_inits.results.len()); + let results: Results<_> = + itertools::izip!(borrows.results, uninits.results, ever_inits.results) .map(|(borrows, uninits, ever_inits)| BorrowckDomain { borrows, uninits, ever_inits }) .collect(); - Results { analysis, entry_states } + (analysis, results) } pub(crate) struct BorrowckInferCtxt<'tcx> { diff --git a/compiler/rustc_mir_dataflow/src/framework/cursor.rs b/compiler/rustc_mir_dataflow/src/framework/cursor.rs index d5005768b80b..3f6e7a066192 100644 --- a/compiler/rustc_mir_dataflow/src/framework/cursor.rs +++ b/compiler/rustc_mir_dataflow/src/framework/cursor.rs @@ -1,5 +1,6 @@ //!

It was broken out of #130227, which needed them to be able to remove unused annotations after computation without recomputing the SCCs themselves. As a drive-by it also removes some redundant code from the hot loop in SCC construction for a performance improvement. --- .../rustc_borrowck/src/constraints/mod.rs | 24 +-- .../rustc_borrowck/src/region_infer/mod.rs | 53 +++++- .../src/graph/scc/mod.rs | 132 ++++++------- .../src/graph/scc/tests.rs | 176 +++++++++++------- 4 files changed, 227 insertions(+), 158 deletions(-) diff --git a/compiler/rustc_borrowck/src/constraints/mod.rs b/compiler/rustc_borrowck/src/constraints/mod.rs index a52269df6828..514bbfe359b1 100644 --- a/compiler/rustc_borrowck/src/constraints/mod.rs +++ b/compiler/rustc_borrowck/src/constraints/mod.rs @@ -7,7 +7,7 @@ use rustc_middle::ty::{RegionVid, TyCtxt, VarianceDiagInfo}; use rustc_span::Span; use tracing::{debug, instrument}; -use crate::region_infer::{ConstraintSccs, RegionDefinition, RegionTracker}; +use crate::region_infer::{AnnotatedSccs, ConstraintSccs, RegionDefinition, SccAnnotations}; use crate::type_check::Locations; use crate::universal_regions::UniversalRegions; @@ -61,12 +61,14 @@ impl<'tcx> OutlivesConstraintSet<'tcx> { &self, static_region: RegionVid, definitions: &IndexVec>, - ) -> ConstraintSccs { + ) -> AnnotatedSccs { let constraint_graph = self.graph(definitions.len()); let region_graph = &constraint_graph.region_graph(self, static_region); - ConstraintSccs::new_with_annotation(®ion_graph, |r| { - RegionTracker::new(r, &definitions[r]) - }) + let mut annotation_visitor = SccAnnotations::new(definitions); + ( + ConstraintSccs::new_with_annotation(®ion_graph, &mut annotation_visitor), + annotation_visitor.scc_to_annotation, + ) } /// This method handles Universe errors by rewriting the constraint @@ -79,12 +81,12 @@ impl<'tcx> OutlivesConstraintSet<'tcx> { /// eventually go away. /// /// For a more precise definition, see the documentation for - /// [`RegionTracker::has_incompatible_universes()`]. + /// [`crate::region_infer::RegionTracker`]. /// /// This edge case used to be handled during constraint propagation /// by iterating over the strongly connected components in the constraint /// graph while maintaining a set of bookkeeping mappings similar - /// to what is stored in `RegionTracker` and manually adding 'sttaic as + /// to what is stored in `RegionTracker` and manually adding 'static as /// needed. /// /// It was rewritten as part of the Polonius project with the goal of moving @@ -108,9 +110,9 @@ impl<'tcx> OutlivesConstraintSet<'tcx> { &mut self, universal_regions: &UniversalRegions<'tcx>, definitions: &IndexVec>, - ) -> ConstraintSccs { + ) -> AnnotatedSccs { let fr_static = universal_regions.fr_static; - let sccs = self.compute_sccs(fr_static, definitions); + let (sccs, annotations) = self.compute_sccs(fr_static, definitions); // Changed to `true` if we added any constraints to `self` and need to // recompute SCCs. @@ -124,7 +126,7 @@ impl<'tcx> OutlivesConstraintSet<'tcx> { continue; } - let annotation = sccs.annotation(scc); + let annotation = annotations[scc]; // If this SCC participates in a universe violation, // e.g. if it reaches a region with a universe smaller than @@ -154,7 +156,7 @@ impl<'tcx> OutlivesConstraintSet<'tcx> { self.compute_sccs(fr_static, definitions) } else { // If we didn't add any back-edges; no more work needs doing - sccs + (sccs, annotations) } } } diff --git a/compiler/rustc_borrowck/src/region_infer/mod.rs b/compiler/rustc_borrowck/src/region_infer/mod.rs index c256051c122f..d483092d9b5a 100644 --- a/compiler/rustc_borrowck/src/region_infer/mod.rs +++ b/compiler/rustc_borrowck/src/region_infer/mod.rs @@ -47,12 +47,13 @@ mod reverse_sccs; pub(crate) mod values; -pub(crate) type ConstraintSccs = Sccs; +pub(crate) type ConstraintSccs = Sccs; +pub(crate) type AnnotatedSccs = (ConstraintSccs, IndexVec); /// An annotation for region graph SCCs that tracks -/// the values of its elements. +/// the values of its elements.

I've recently realized that shared-generics includes all instantiations of some_generic_function in the following snippet: ```rs pub fn some_generic_function(_: impl Fn()) {} pub fn non_generic_function() { some_generic_function(|| {}); some_generic_function(|| {}); some_generic_function(|| {}); some_generic_function(|| {}); some_generic_function(|| {}); some_generic_function(|| {}); some_generic_function(|| {}); } ``` even though none of these instantiations can actually be created from outside of `non_generic_function`. This PR makes shared-generics account for visibilities of generic arguments; an item is only considered for exporting if it is reachable from the outside or if all of it's arguments are visible outside of the local crate. This PR reduces incremental build time for Zed (touch edito.rs scenario) from 12.4s to 10.4s.

Most of the time is spent in collect_items_rec. This PR aims to reduce the number of locks taking place; instead of locking output MonoItems once per children of current node, we do so once per *parent*. We also get to reuse locks for mentioned and used items. While this commit does not reduce Wall time of Zed's build, it does shave off `cargo build -j1` from 43s to 41.5s. --- compiler/rustc_monomorphize/src/collector.rs | 64 +++++++++++--------- compiler/rustc_monomorphize/src/lib.rs | 1 + 2 files changed, 38 insertions(+), 27 deletions(-) diff --git a/compiler/rustc_monomorphize/src/collector.rs b/compiler/rustc_monomorphize/src/collector.rs index 76dad6b35714..1e3744e19f54 100644 --- a/compiler/rustc_monomorphize/src/collector.rs +++ b/compiler/rustc_monomorphize/src/collector.rs @@ -205,6 +205,7 @@ //! this is not implemented however: a mono item will be produced //! regardless of whether it is actually needed or not. +use std::cell::OnceCell; use std::path::PathBuf; use rustc_attr_parsing::InlineAttr; @@ -348,6 +349,27 @@ impl<'tcx> Extend>> for MonoItems<'tcx> { } } +fn collect_items_root<'tcx>( + tcx: TyCtxt<'tcx>, + starting_item: Spanned>, + state: &SharedState<'tcx>, + recursion_limit: Limit, +) { + if !state.visited.lock_mut().insert(starting_item.node) { + // We've been here already, no need to search again. + return; + } + let mut recursion_depths = DefIdMap::default(); + collect_items_rec( + tcx, + starting_item, + state, + &mut recursion_depths, + recursion_limit, + CollectionMode::UsedItems, + ); +} + /// Collect all monomorphized items reachable from `starting_point`, and emit a note diagnostic if a /// post-monomorphization error is encountered during a collection step. /// @@ -362,24 +384,6 @@ fn collect_items_rec<'tcx>( recursion_limit: Limit, mode: CollectionMode, ) { - if mode == CollectionMode::UsedItems { - if !state.visited.lock_mut().insert(starting_item.node) { - // We've been here already, no need to search again. - return; - } - } else { - if state.visited.lock().contains(&starting_item.node) { - // We've already done a *full* visit on this one, no need to do the "mention" visit. - return; - } - if !state.mentioned.lock_mut().insert(starting_item.node) { - // We've been here already, no need to search again. - return; - } - // There's some risk that we first do a 'mention' visit and then a full visit.

Val" Date: Wed, 30 Apr 2025 15:39:52 -0700 Subject: [PATCH 096/302] Change rustc_driver dependency on stable_mir crate This fixes issues with RustAnalyzer not finding stable_mir crate. It is also part of the long term architecture plan for these crates, since we are moving towards having stable_mir depend on rustc_smir and not the other way around. I believe this is an utility function that will come handy eventually for stable_mir users, but I'm keeping it as part of rustc_internal since it initializes the StableMir context and requires `TyCtxt`. Finally, I added the rustc_internal crate under a feature since the APIs from this module shall not be stabilized. --- Cargo.lock | 2 +- compiler/rustc_driver_impl/Cargo.toml | 2 +- compiler/rustc_driver_impl/src/pretty.rs | 2 +- compiler/stable_mir/Cargo.toml | 6 ++++++ compiler/stable_mir/src/lib.rs | 4 ++++ 5 files changed, 13 insertions(+), 3 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 60daa453c60d..821512a53c2c 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3583,13 +3583,13 @@ dependencies = [ "rustc_query_system", "rustc_resolve", "rustc_session", - "rustc_smir", "rustc_span", "rustc_target", "rustc_trait_selection", "rustc_ty_utils", "serde_json", "shlex", + "stable_mir", "tracing", "windows 0.59.0", ] diff --git a/compiler/rustc_driver_impl/Cargo.toml b/compiler/rustc_driver_impl/Cargo.toml index c823d11126e2..9da4f2dbc273 100644 --- a/compiler/rustc_driver_impl/Cargo.toml +++ b/compiler/rustc_driver_impl/Cargo.toml @@ -44,13 +44,13 @@ rustc_privacy = { path = "../rustc_privacy" } rustc_query_system = { path = "../rustc_query_system" } rustc_resolve = { path = "../rustc_resolve" } rustc_session = { path = "../rustc_session" } -rustc_smir = { path = "../rustc_smir" } rustc_span = { path = "../rustc_span" } rustc_target = { path = "../rustc_target" } rustc_trait_selection = { path = "../rustc_trait_selection" } rustc_ty_utils = { path = "../rustc_ty_utils" } serde_json = "1.0.59" shlex = "1.0" +stable_mir = { path = "../stable_mir", features = ["rustc_internal"] } tracing = { version = "0.1.35" } # tidy-alphabetical-end diff --git a/compiler/rustc_driver_impl/src/pretty.rs b/compiler/rustc_driver_impl/src/pretty.rs index 16d70af7e05d..ec77043cd128 100644 --- a/compiler/rustc_driver_impl/src/pretty.rs +++ b/compiler/rustc_driver_impl/src/pretty.rs @@ -10,8 +10,8 @@ use rustc_middle::ty::{self, TyCtxt}; use rustc_mir_build::thir::print::{thir_flat, thir_tree}; use rustc_session::Session; use rustc_session::config::{OutFileName, PpHirMode, PpMode, PpSourceMode}; -use rustc_smir::rustc_internal::pretty::write_smir_pretty; use rustc_span::{FileName, Ident}; +use stable_mir::rustc_internal::pretty::write_smir_pretty; use tracing::debug; use {rustc_ast as ast, rustc_hir_pretty as pprust_hir}; diff --git a/compiler/stable_mir/Cargo.toml b/compiler/stable_mir/Cargo.toml index 3a01ee5783ee..516c8e9c718b 100644 --- a/compiler/stable_mir/Cargo.toml +++ b/compiler/stable_mir/Cargo.toml @@ -5,3 +5,9 @@ edition = "2024" [dependencies] rustc_smir = { path = "../rustc_smir" } + +[features] +# Provides access to APIs that expose internals of the rust compiler. +# APIs enabled by this feature are unstable.

The Zic64b extension constrains the cache line to naturally-aligned 64 bytes that would make certain memory operations (like zeroing the memory using the Zicboz extension) easier. The Zicbom and Zicbop extensions enable managing cache block-based operations (the Zicbop contains hints that will work as a NOP when this extension is absent and the Zicbom contains control instructions). Of which, the Zicbom extension is going to be discoverable from the Linux kernel (as of the version 6.15-rc4) and this commit prepares for corresponding stdarch changes. The Zicc* extensions add certain constraints to "the main memory" (usually true on the user mode application on the application-class processor but those extensions make sure such constraints exist). --- compiler/rustc_target/src/target_features.rs | 7 +++++++ tests/ui/check-cfg/target_feature.stderr | 7 +++++++ 2 files changed, 14 insertions(+) diff --git a/compiler/rustc_target/src/target_features.rs b/compiler/rustc_target/src/target_features.rs index 9031e0530c58..99f39b34b629 100644 --- a/compiler/rustc_target/src/target_features.rs +++ b/compiler/rustc_target/src/target_features.rs @@ -531,7 +531,14 @@ static RISCV_FEATURES: &[(&str, Stability, ImpliedFeatures)] = &[ ("zfinx", Unstable(sym::riscv_target_feature), &["zicsr"]), ("zhinx", Unstable(sym::riscv_target_feature), &["zhinxmin"]), ("zhinxmin", Unstable(sym::riscv_target_feature), &["zfinx"]), + ("zic64b", Unstable(sym::riscv_target_feature), &[]), + ("zicbom", Unstable(sym::riscv_target_feature), &[]), + ("zicbop", Unstable(sym::riscv_target_feature), &[]), ("zicboz", Unstable(sym::riscv_target_feature), &[]), + ("ziccamoa", Unstable(sym::riscv_target_feature), &[]), + ("ziccif", Unstable(sym::riscv_target_feature), &[]), + ("zicclsm", Unstable(sym::riscv_target_feature), &[]), + ("ziccrse", Unstable(sym::riscv_target_feature), &[]), ("zicntr", Unstable(sym::riscv_target_feature), &["zicsr"]), ("zicond", Unstable(sym::riscv_target_feature), &[]), ("zicsr", Unstable(sym::riscv_target_feature), &[]), diff --git a/tests/ui/check-cfg/target_feature.stderr b/tests/ui/check-cfg/target_feature.stderr index 4f7b8345e86a..174058773549 100644 --- a/tests/ui/check-cfg/target_feature.stderr +++ b/tests/ui/check-cfg/target_feature.stderr @@ -329,7 +329,14 @@ LL | cfg!(target_feature = "_UNEXPECTED_VALUE"); `zfinx` `zhinx` `zhinxmin` +`zic64b` +`zicbom` +`zicbop` `zicboz` +`ziccamoa` +`ziccif` +`zicclsm` +`ziccrse` `zicntr` `zicond` `zicsr` From 501a539bbe74164384ebf42165b058bc01f6b5a2 Mon Sep 17 00:00:00 2001 From: Tsukasa OI Date: Wed, 30 Apr 2025 06:53:22 +0000 Subject: [PATCH 100/302] rustc_target: RISC-V: Add BF16 extensions This commit adds three ratified unprivileged RISC-V extensions related to BFloat16 (BF16) handling.

Most platforms use `vec::IntoIter` as the inner type, so prioritize delegating to the methods it provides. `std::env::Args` is implemented atop `std::env::ArgsOs` and performs UTF-8 validation with a panic for invalid data. This is a visible effect which users certainly rely on, so we can't skip any arguments. Any further iterator methods would skip some elements, so no change is needed for that type. Add `#[inline]` for any methods which simply wrap the inner iterator. --- library/std/src/env.rs | 73 +++++++++++++++++++++++- library/std/src/lib.rs | 3 + library/std/src/sys/args/common.rs | 66 +++++++++++++++++++-- library/std/src/sys/args/sgx.rs | 76 ++++++++++++++++++++----- library/std/src/sys/args/unsupported.rs | 18 ++++-- 5 files changed, 211 insertions(+), 25 deletions(-) diff --git a/library/std/src/env.rs b/library/std/src/env.rs index 1593969e114a..ce2dc7952207 100644 --- a/library/std/src/env.rs +++ b/library/std/src/env.rs @@ -12,9 +12,11 @@ use crate::error::Error;

Since mixing deref patterns with normal constructors is pretty niche (currently it only makes sense for `Cow`), emitting an error lets us avoid committing to supporting mixed exhaustiveness without a good answer for the diagnostics. --- compiler/rustc_pattern_analysis/messages.ftl | 4 ++ compiler/rustc_pattern_analysis/src/errors.rs | 14 ++++- compiler/rustc_pattern_analysis/src/rustc.rs | 53 +++++++++++++++++++ .../usefulness/mixed-constructors.rs | 48 +++++++++++++++++ .../usefulness/mixed-constructors.stderr | 43 +++++++++++++++ 5 files changed, 161 insertions(+), 1 deletion(-) create mode 100644 tests/ui/pattern/deref-patterns/usefulness/mixed-constructors.rs create mode 100644 tests/ui/pattern/deref-patterns/usefulness/mixed-constructors.stderr diff --git a/compiler/rustc_pattern_analysis/messages.ftl b/compiler/rustc_pattern_analysis/messages.ftl index 41a1d958f109..d3a3107f8e89 100644 --- a/compiler/rustc_pattern_analysis/messages.ftl +++ b/compiler/rustc_pattern_analysis/messages.ftl @@ -6,6 +6,10 @@ pattern_analysis_excluside_range_missing_max = exclusive range missing `{$max}` .label = this range doesn't match `{$max}` because `..` is an exclusive range .suggestion = use an inclusive range instead +pattern_analysis_mixed_deref_pattern_constructors = mix of deref patterns and normal constructors + .deref_pattern_label = matches on the result of dereferencing `{$smart_pointer_ty}` + .normal_constructor_label = matches directly on `{$smart_pointer_ty}` + pattern_analysis_non_exhaustive_omitted_pattern = some variants are not matched explicitly .help = ensure that all variants are matched explicitly by adding the suggested match arms .note = the matched value is of type `{$scrut_ty}` and the `non_exhaustive_omitted_patterns` attribute was found diff --git a/compiler/rustc_pattern_analysis/src/errors.rs b/compiler/rustc_pattern_analysis/src/errors.rs index e60930d6cd21..156ba9737673 100644 --- a/compiler/rustc_pattern_analysis/src/errors.rs +++ b/compiler/rustc_pattern_analysis/src/errors.rs @@ -1,5 +1,5 @@ use rustc_errors::{Diag, EmissionGuarantee, Subdiagnostic}; -use rustc_macros::{LintDiagnostic, Subdiagnostic}; +use rustc_macros::{Diagnostic, LintDiagnostic, Subdiagnostic}; use rustc_middle::ty::Ty; use rustc_span::Span; @@ -133,3 +133,15 @@ pub(crate) struct NonExhaustiveOmittedPatternLintOnArm { pub lint_level: &'static str, pub lint_name: &'static str, } + +#[derive(Diagnostic)] +#[diag(pattern_analysis_mixed_deref_pattern_constructors)] +pub(crate) struct MixedDerefPatternConstructors<'tcx> { + #[primary_span] + pub spans: Vec, + pub smart_pointer_ty: Ty<'tcx>, + #[label(pattern_analysis_deref_pattern_label)] + pub deref_pattern_label: Span, + #[label(pattern_analysis_normal_constructor_label)] + pub normal_constructor_label: Span, +} diff --git a/compiler/rustc_pattern_analysis/src/rustc.rs b/compiler/rustc_pattern_analysis/src/rustc.rs index 050b48d082b7..a89d01dcbbe4 100644 --- a/compiler/rustc_pattern_analysis/src/rustc.rs +++ b/compiler/rustc_pattern_analysis/src/rustc.rs @@ -1106,6 +1106,14 @@ pub fn analyze_match<'p, 'tcx>( scrut_ty: Ty<'tcx>, ) -> Result, ErrorGuaranteed> { let scrut_ty = tycx.reveal_opaque_ty(scrut_ty); + + // The analysis doesn't support deref patterns mixed with normal constructors; error if present. + // FIXME(deref_patterns): This only needs to run when a deref pattern was found during lowering. + if tycx.tcx.features().deref_patterns() { + let pat_column = PatternColumn::new(arms); + detect_mixed_deref_pat_ctors(tycx, &pat_column)?; + } + let scrut_validity = PlaceValidity::from_bool(tycx.known_valid_scrutinee); let report = compute_match_usefulness( tycx, @@ -1125,6 +1133,51 @@ pub fn analyze_match<'p, 'tcx>( Ok(report) } +// FIXME(deref_patterns): Currently it's the responsibility of the frontend (rustc or rust-analyzer) +// to ensure that deref patterns don't appear in the same column as normal constructors.

This commit updates the cargo() wrapper to call set_host_compiler_dylib_path(), aligning its behavior with the existing rustc() wrapper: https://github.com/rust-lang/rust/blob/f76c7367c6363d33ddb5a93b5de0d158b2d827f6/src/tools/run-make-support/src/external_deps/rustc.rs#L39 This ensures that Cargo invocations during tests inherit the necessary dylib paths, avoiding errors related to missing shared libraries in rpath-less builds.
