Updates LLVM to pick up the cherry-picked support for correctly handling exception handling with aggregates passed by value. This will be necessary to continue to support Emscripten's exception handling once we switch using Emscripten's LLVM backend. See rust-lang#63649.
Implement (HashMap) Entry::insert as per rust-lang#60142 Implementation of `Entry::insert` as per @SimonSapin's comment on rust-lang#60142. This requires a patch to hashbrown: ```diff diff --git a/src/rustc_entry.rs b/src/rustc_entry.rs index fefa5c3..7de8300 100644 --- a/src/rustc_entry.rs +++ b/src/rustc_entry.rs @@ -546,6 +546,32 @@ impl<'a, K, V> RustcVacantEntry<'a, K, V> { let bucket = self.table.insert_no_grow(self.hash, (self.key, value)); unsafe { &mut bucket.as_mut().1 } } + + /// Sets the value of the entry with the RustcVacantEntry's key, + /// and returns a RustcOccupiedEntry. + /// + /// # Examples + /// + /// ``` + /// use hashbrown::HashMap; + /// use hashbrown::hash_map::RustcEntry; + /// + /// let mut map: HashMap<&str, u32> = HashMap::new(); + /// + /// if let RustcEntry::Vacant(v) = map.rustc_entry("poneyland") { + /// let o = v.insert_and_return(37); + /// assert_eq!(o.get(), &37); + /// } + /// ``` + #[inline] + pub fn insert_and_return(self, value: V) -> RustcOccupiedEntry<'a, K, V> { + let bucket = self.table.insert_no_grow(self.hash, (self.key, value)); + RustcOccupiedEntry { + key: None, + elem: bucket, + table: self.table + } + } } impl<K, V> IterMut<'_, K, V> { ``` This is also only an implementation for HashMap. I tried implementing for BTreeMap, but I don't really understand BTreeMap's internals and require more guidance on implementing the equivalent `VacantEntry::insert_and_return` such that it returns an `OccupiedEntry`. Notably, following the original PR's modifications I end up needing a `Handle<NodeRef<marker::Mut<'_>, _, _, marker::LeafOrInternal>, _>` while I only have a `Handle<NodeRef<marker::Mut<'_>, _, _, marker::Internal>, _>` and don't know how to proceed. (To be clear, I'm not asking for guidance right now; I'd be happy getting only the HashMap implementation — the subject of this PR — reviewed and ready, and leave the BTreeMap implementation for a latter PR.)
…varkor Function pointers as const generic arguments Makes function pointers as const generic arguments usable. Fixes rust-lang#62395 r? @varkor
`#[track_caller]` feature gate (RFC 2091 1/N) RFC text: https://github.com/rust-lang/rfcs/blob/master/text/2091-inline-semantic.md Tracking issue: rust-lang#47809 I started with @ayosec's commit to add the feature gate with tests and rebased it onto current master. I fixed up some tidy lints and added a test.
Suggest to add `move` keyword for generator capture Closes rust-lang#64382 r? @estebank
add more info in debug traces for gcu merging to help in investigation of CGU partitioning problems e.g rust-lang#64913
