expand vec![] to Vec::new() #70632

tspiteri · 2020-03-31T19:42:38Z

The current expansion of vec![] calls into_vec on a boxed slice, which results in longer IR, and even after optimization, some unwinding artifacts are still present in the IR. This PR uses Vec::new() for vec![].

This also allows vec![] to be used in const expressions.

This does allow vec![] in const exprs, but I think that's fine personally.

matthiaskrgr · 2020-03-31T20:34:46Z

Curious if this PR improves the situation about #54475

tspiteri · 2020-03-31T21:23:39Z

@matthiaskrgr I don't think so, in fact I think it only stops the hack workaround from working, as with the PR vec![] would expand to Vec::new(), but then the workaround is quite finicky, even changing the conditional to false (which it is) breaks it.

LukasKalbertodt · 2020-03-31T22:08:22Z

Just to be sure, cc @rust-lang/wg-const-eval

I also don't think merging this is a problem. There shouldn't be a reason why vec![] should not be equivalent to Vec::new().

expand vec![] to Vec::new() The current expansion of `vec![]` calls `into_vec` on a boxed slice, which results in longer IR, and even after optimization, some unwinding artifacts are still present in the IR. This PR uses `Vec::new()` for `vec![]`. This also allows `vec![]` to be used in const expressions.

Yeah there shouldn't be a problem, but note that reverting this PR will become a breaking change.

Rust 1.44 made `vec![]` expand to `Vec::new()` (rust-lang/rust#70632). As such clippy is now (somewhat correctly) interpreting that the macro could be used points-free. clippy should be smart enough to not substitute the expanded macro, but for now we can silence the errors by using a points-free constructor.
