2022-01-18Auto merge of #87648 - JulianKnodt:const_eq_constrain, r=oli-obkbors-7/+8
allow eq constraints on associated constants Updates #70256 (cc `@varkor,` `@Centril)`
2022-01-17Abstract the pretty printer's ringbuffer to be infinitely sizedDavid Tolnay-22/+67
2022-01-17Use Term in ProjectionPredicatekadmin-3/+1
ProjectionPredicate should be able to handle both associated types and consts so this adds the first step of that. It mainly just pipes types all the way down, not entirely sure how to handle consts, but hopefully that'll come with time.
2022-01-17Add termkadmin-7/+6
Instead of having a separate enum variant for types and consts have one but have either a const or type.

2022-01-17Auto merge of #92816 - tmiasko:rm-llvm-asm, r=Amanieubors-56/+0
Remove deprecated LLVM-style inline assembly The `llvm_asm!` was deprecated back in #87590 1.56.0, with intention to remove it once `asm!` was stabilized, which already happened in #91728 1.59.0. Now it is time to remove `llvm_asm!` to avoid continued maintenance cost. Closes #70173. Closes #92794. Closes #87612. Closes #82065. cc `@rust-lang/wg-inline-asm` r? `@Amanieu`
2022-01-17Rollup merge of #92921 - dtolnay:printernew, r=wesleywiserMatthias Krüger-25/+25
Rename Printer constructor from mk_printer() to Printer::new() The original naming is left over from 2011 which was before impl blocks and associated functions existed. https://github.com/rust-lang/rust/blob/21313d623a505086b2973f30c19db4f1d6ec8f61/src/comp/pretty/pp.rs
2022-01-16Rollup merge of #92487 - dtolnay:traitalias, r=matthewjasperMatthias Krüger-3/+3
Fix unclosed boxes in pretty printing of TraitAlias This was causing trait aliases to not even render at all in stringified / pretty printed output. ```rust macro_rules! repro { ($item:item) => { stringify!($item) }; } fn main() { println!("{:?}", repro!(pub trait Trait<T> = Sized where T: 'a;)); } ``` Before:&ensp;`""` After:&ensp;`"pub trait Trait<T> = Sized where T: 'a;"` The fix is copied from how `head`/`end` for `ItemKind::Use`, `ItemKind::ExternCrate`, and `ItemKind::Mod` are all done in the pretty printer: https://github.com/rust-lang/rust/blob/dd3ac41495e85a9b7b5cb3186379d02ce17e51fe/compiler/rustc_ast_pretty/src/pprust/state.rs#L1178-L1184

2022-01-07Rollup merge of #92336 - dtolnay:printstateself, r=michaelwoeristerEric Huss-24/+24
Remove &self from PrintState::to_string The point of `PrintState::to_string` is to create a `State` and evaluate the caller's closure on it: https://github.com/rust-lang/rust/blob/e9fbe79292783972a222afd270db3f77c0b4f3c8/compiler/rustc_ast_pretty/src/pprust/state.rs#L868-L872 Making the caller *also* construct and pass in a `State`, which is then ignored, was confusing.
2022-01-06Rollup merge of #92417 - dtolnay:printimpl, r=jackh726Matthias Krüger-3/+6
Fix spacing and ordering of words in pretty printed Impl Follow-up to #92238 fixing one of the FIXMEs. ```rust macro_rules! repro { ($item:item) => { stringify!($item) }; } fn main() { println!("{}", repro!(impl<T> Struct<T> {})); println!("{}", repro!(impl<T> const Trait for T {})); } ``` Before:&ensp;`impl <T> Struct<T> {}` After:&ensp;`impl<T> Struct<T> {}` Before:&ensp;`impl const <T> Trait for T {}` :crying_cat_face: After:&ensp;`impl<T> const Trait for T {}`
2022-01-03Rollup merge of #92418 - dtolnay:emptystructpat, r=michaelwoeristerMatthias Krüger-2/+8

2022-01-01Rollup merge of #92420 - dtolnay:patrange, r=Mark-SimulacrumMatthias Krüger-1/+0
Fix whitespace in pretty printed PatKind::Range Follow-up to #92238 fixing one of the FIXMEs. ```rust macro_rules! repro { ($pat:pat) => { stringify!($pat) }; } fn main() { println!("{}", repro!(0..=1)); } ``` Before:&ensp;`0 ..=1` After:&ensp;`0..=1` The canonical spacing applied by rustfmt has no space after the lower expr. Rustc's parser diagnostics also do not put a space there: https://github.com/rust-lang/rust/blob/df96fb166f59431e3de443835e50d5b8a7a4adb0/compiler/rustc_parse/src/parser/pat.rs#L754
2022-01-01Rollup merge of #92412 - dtolnay:tryspace, r=Mark-SimulacrumMatthias Krüger-1/+0
Fix double space in pretty printed TryBlock Follow-up to #92238 fixing one of the FIXMEs. ```rust macro_rules! repro { ($expr:expr) => { stringify!($expr) }; } fn main() { println!("{}", repro!(try {})); } ``` Before:&ensp;<code>try&nbsp;&nbsp;{}</code> After:&ensp;<code>try&nbsp;{}</code> The `head` helper already appends a space: https://github.com/rust-lang/rust/blob/2b67c30bfece00357d5fc09d99b49f21066f04ba/compiler/rustc_ast_pretty/src/pprust/state.rs#L654-L664 so doing `head` followed by `space` resulted in a double space: https://github.com/rust-lang/rust/blob/2b67c30bfece00357d5fc09d99b49f21066f04ba/compiler/rustc_ast_pretty/src/pprust/state.rs#L2241-L2242

2021-12-29Rollup merge of #92372 - dtolnay:fntype, r=jackh726Matthias Krüger-4/+1
Print space after formal generic params in fn type Follow-up to #92238 fixing one of the FIXMEs. ```rust macro_rules! repro { ($ty:ty) => { stringify!($ty) }; } fn main() { println!("{}", repro!(for<'a> fn(&'a u8))); } ``` Before:&ensp;`for<'a>fn(&'a u8)` After:&ensp;`for<'a> fn(&'a u8)` The pretty printer's `print_formal_generic_params` already prints formal generic params correctly with a space, we just need to call it when printing BareFn types instead of reimplementing the printing incorrectly without a space. https://github.com/rust-lang/rust/blob/83b15bfe1c15f325bc186ebfe3691b729ed59f2b/compiler/rustc_ast_pretty/src/pprust/state.rs#L1394-L1400

2021-12-07Rollup merge of #91562 - dtolnay:asyncspace, r=Mark-SimulacrumMatthias Krüger-1/+0
Pretty print async block without redundant space **Repro:** ```rust macro_rules! m { ($e:expr) => { stringify!($e) }; } fn main() { println!("{:?}", m!(async {})); } ``` **Before:** <code>"async&nbsp;&nbsp;{}"</code> **After:** `"async {}"` <br> In this function: https://github.com/rust-lang/rust/blob/65c55bf931a55e6b1e5ed14ad8623814a7386424/compiler/rustc_ast_pretty/src/pprust/state.rs#L2049-L2051 the `print_capture_clause` and `word_nbsp`/`word_space` calls already put a space after the `async` and `move` keywords being printed. The extra `self.s.space()` call removed by this PR resulted in the redundant double space. https://github.com/rust-lang/rust/blob/65c55bf931a55e6b1e5ed14ad8623814a7386424/compiler/rustc_ast_pretty/src/pprust/state.rs#L2640-L2645 https://github.com/rust-lang/rust/blob/65c55bf931a55e6b1e5ed14ad8623814a7386424/compiler/rustc_ast_pretty/src/helpers.rs#L34-L37 https://github.com/rust-lang/rust/blob/65c55bf931a55e6b1e5ed14ad8623814a7386424/compiler/rustc_ast_pretty/src/helpers.rs#L5-L8
