- It's `--print`, not `--prints`. - `-Ztime` and `-Ztime-passes` print to stderr, not stdout.
The compiler currently has `-Ztime` and `-Ztime-passes`. I've used `-Ztime-passes` for years but only recently learned about `-Ztime`. What's the difference? Let's look at the `-Zhelp` output: ``` -Z time=val -- measure time of rustc processes (default: no) -Z time-passes=val -- measure time of each rustc pass (default: no) ``` The `-Ztime-passes` description is clear, but the `-Ztime` one is less so. Sounds like it measures the time for the entire process? No. The real difference is that `-Ztime-passes` prints out info about passes, and `-Ztime` does the same, but only for a subset of those passes. More specifically, there is a distinction in the profiling code between a "verbose generic activity" and an "extra verbose generic activity". `-Ztime-passes` prints both kinds, while `-Ztime` only prints the first one. (It took me a close reading of the source code to determine this difference.) In practice this distinction has low value. Perhaps in the past the "extra verbose" output was more voluminous, but now that we only print stats for a pass if it exceeds 5ms or alters the RSS, `-Ztime-passes` is less spammy. Also, a lot of the "extra verbose" cases are for individual lint passes, and you need to also use `-Zno-interleave-lints` to see those anyway. Therefore, this commit removes `-Ztime` and the associated machinery. One thing to note is that the existing "extra verbose" activities all have an extra string argument, so the commit adds the ability to accept an extra argument to the "verbose" activities.
`print_time_passes_entry` unconditionally prints data about a pass. The most commonly used call site, in `VerboseTimingGuard::drop`, guards it with a `should_print_passes` test. But there are a couple of other call sites that don't do that test. This commit moves the `should_print_passes` test within `print_time_passes_entry` so that all passes are treated equally.
…lcnr make `compare_const_impl` a query and use it in `instance.rs` Fixes rust-lang#88365 the bug in rust-lang#88365 was caused by some `instance.rs` code using the `PartialEq` impl on `Ty` to check that the type of the associated const in an impl is the same as the type of the associated const in the trait definition. This was wrong for two reasons: - the check typeck does is that the impl type is a subtype of the trait definition's type (see `mismatched_impl_ty_2.rs` which [was ICEing](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=f6d60ebe6745011f0d52ab2bc712025d) before this PR on stable) - it assumes that if two types are equal then the `PartialEq` impl will reflect that which isnt true for higher ranked types or type level constants when `feature(generic_const_exprs)` is enabled (see `mismatched_impl_ty_3.rs` for higher ranked types which was [ICEing on stable](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=d7af131a655ed515b035624626c62c71)) r? `@lcnr`
Fix overconstrained Send impls in btree internals Fixes dtolnay/async-trait#215. Minimal repro: ```rust use std::collections::btree_map::Iter; fn require_send<T: Send>(_: T) {} fn main() { require_send(async { let _iter = None::<Iter<(), &()>>; async {}.await; }); } ``` ```console error: higher-ranked lifetime error --> src/main.rs:6:5 | 6 | / require_send(async { 7 | | let _iter = None::<Iter<(), &()>>; 8 | | async {}.await; 9 | | }); | |______^ | = note: could not prove `impl Future<Output = ()>: Send` ``` Not-quite-so-minimal repro: ```rust use std::collections::BTreeMap; use std::future::Future; fn spawn<T: Future + Send>(_: T) {} async fn f() { let map = BTreeMap::<u32, Box<dyn Send + Sync>>::new(); for _ in &map { async {}.await; } } fn main() { spawn(f()); } ``` ```console error: higher-ranked lifetime error --> src/main.rs:14:5 | 14 | spawn(f()); | ^^^^^^^^^^ | = note: could not prove `impl Future<Output = ()>: Send` ``` I am not familiar with the btree internals, but it seems clear to me that the `async fn f` above should return a Send future. Using HashMap instead of BTreeMap in that code makes it already return a Send future. The _"higher-ranked lifetime error"_ message may be a regression in Rust 1.63. Using older compilers the error message was more detailed: ```console error: implementation of `Send` is not general enough --> src/main.rs:14:5 | 14 | spawn(f()); | ^^^^^ implementation of `Send` is not general enough | = note: `Send` would have to be implemented for the type `alloc::collections::btree::node::NodeRef<alloc::collections::btree::node::marker::Immut<'0>, u32, Box<(dyn Send + Sync + '1)>, alloc::collections::btree::node::marker::LeafOrInternal>`, for any two lifetimes `'0` and `'1`... = note: ...but `Send` is actually implemented for the type `alloc::collections::btree::node::NodeRef<alloc::collections::btree::node::marker::Immut<'2>, u32, Box<dyn Send + Sync>, alloc::collections::btree::node::marker::LeafOrInternal>`, for some specific lifetime `'2` error: implementation of `Send` is not general enough --> src/main.rs:14:5 | 14 | spawn(f()); | ^^^^^ implementation of `Send` is not general enough | = note: `Send` would have to be implemented for the type `alloc::collections::btree::node::NodeRef<alloc::collections::btree::node::marker::Immut<'0>, u32, Box<(dyn Send + Sync + '1)>, alloc::collections::btree::node::marker::Leaf>`, for any two lifetimes `'0` and `'1`... = note: ...but `Send` is actually implemented for the type `alloc::collections::btree::node::NodeRef<alloc::collections::btree::node::marker::Immut<'2>, u32, Box<dyn Send + Sync>, alloc::collections::btree::node::marker::Leaf>`, for some specific lifetime `'2` ```
