This doesn't work when the MIR inliner inlines code as it creates spans with expansion information set to `ExprKind::Inlined` and results in the line number being attributed to the inline callsite rather than the normal line number of the inlined code. --- compiler/rustc_middle/src/ty/mod.rs | 4 +++- compiler/rustc_span/src/lib.rs | 8 +++++++- src/test/codegen/mir-inlined-line-numbers.rs | 2 +- 3 files changed, 11 insertions(+), 3 deletions(-) (limited to 'src/test') diff --git a/compiler/rustc_middle/src/ty/mod.rs b/compiler/rustc_middle/src/ty/mod.rs index 0d7d4054bb3..34938ab05cb 100644 --- a/compiler/rustc_middle/src/ty/mod.rs +++ b/compiler/rustc_middle/src/ty/mod.rs @@ -2522,7 +2522,9 @@ impl<'tcx> TyCtxt<'tcx> { && if self.features().collapse_debuginfo { span.in_macro_expansion_with_collapse_debuginfo() } else { - span.from_expansion() + // Inlined spans should not be collapsed as that leads to all of the + // inlined code being attributed to the inline callsite. + span.from_expansion() && !span.is_inlined() } } diff --git a/compiler/rustc_span/src/lib.rs b/compiler/rustc_span/src/lib.rs index 91eef647713..ec5491116e8 100644 --- a/compiler/rustc_span/src/lib.rs +++ b/compiler/rustc_span/src/lib.rs @@ -558,7 +558,7 @@ impl Span { self.data_untracked().is_dummy() } - /// Returns `true` if this span comes from a macro or desugaring. + /// Returns `true` if this span comes from any kind of macro, desugaring or inlining. #[inline] pub fn from_expansion(self) -> bool { self.ctxt() != SyntaxContext::root() @@ -571,6 +571,12 @@ impl Span { matches!(outer_expn.kind, ExpnKind::Macro(..)) && outer_expn.collapse_debuginfo } + /// Returns `true` if this span comes from MIR inlining. + pub fn is_inlined(self) -> bool { + let outer_expn = self.ctxt().outer_expn_data(); + matches!(outer_expn.kind, ExpnKind::Inlined) + } + /// Returns `true` if `span` originates in a derive-macro's expansion. pub fn in_derive_expansion(self) -> bool { matches!(self.ctxt().outer_expn_data().kind, ExpnKind::Macro(MacroKind::Derive, _)) diff --git a/src/test/codegen/mir-inlined-line-numbers.rs b/src/test/codegen/mir-inlined-line-numbers.rs index 53efe0f5be5..19d83f0eee7 100644 --- a/src/test/codegen/mir-inlined-line-numbers.rs +++ b/src/test/codegen/mir-inlined-line-numbers.rs @@ -20,6 +20,6 @@ pub fn example() { // CHECK-LABEL: @example // CHECK: tail call void @bar(), !dbg [[DBG_ID:![0-9]+]] -// CHECK: [[DBG_ID]] = !DILocation(line: 18, +// CHECK: [[DBG_ID]] = !DILocation(line: 7, // CHECK-SAME: inlinedAt: [[INLINE_ID:![0-9]+]]) // CHECK: [[INLINE_ID]] = !DILocation(line: 18, -- cgit 1.4.1-3-g733a5 From 73d655e9c2106566f328de28aeff6fd3a8ee8e21 Mon Sep 17 00:00:00 2001 From: Ralf Jung Date: Sun, 16 Oct 2022 10:38:48 +0200 Subject: remove redundant Send impls for references also move them next to the trait they are implementing --- library/core/src/marker.rs | 13 ++++++------- src/test/ui/async-await/async-fn-nonsend.stderr | 2 +- 2 files changed, 7 insertions(+), 8 deletions(-) (limited to 'src/test') diff --git a/library/core/src/marker.rs b/library/core/src/marker.rs index d5ed52124e2..bb10caee6e2 100644 --- a/library/core/src/marker.rs +++ b/library/core/src/marker.rs @@ -44,6 +44,12 @@ impl !Send for *const T {} #[stable(feature = "rust1", since = "1.0.0")] impl !Send for *mut T {} +// Most instances arise automatically, but this instance is needed to link up `T: Sync` with +// `&T: Send` (and it also removes the unsound default instance `T Send` -> `&T: Send` that would +// otherwise exist). +#[stable(feature = "rust1", since = "1.0.0")] +unsafe impl Send for &T {} + /// Types with a constant size known at compile time. /// /// All type parameters have an implicit bound of `Sized`.

This commit renames several `def_id: OwnerId` fields as `owner_id`, so those expressions become `item_id.owner_id.def_id`. `item_id.owner_id.local_def_id` would be even clearer, but the use of `def_id` for values of type `LocalDefId` is *very* widespread, so I left that alone. --- compiler/rustc_ast_lowering/src/index.rs | 16 +-- compiler/rustc_ast_lowering/src/item.rs | 26 ++---
