2019-01-14Avoid some `TokenTree`-to-`TokenStream` conversions.Nicholas Nethercote-7/+6
This avoids some allocations.
2019-01-14Remove `ThinTokenStream`.Nicholas Nethercote-70/+21
`TokenStream` is now almost identical to `ThinTokenStream`. This commit removes the latter, replacing it with the former.
2019-01-14Remove `TokenStream::Tree` variant.Nicholas Nethercote-40/+5
`TokenStream::Stream` can represent a token stream containing any number of token trees. `TokenStream::Tree` is the special case representing a single token tree. The latter doesn't occur all that often dynamically, so this commit removes it, which simplifies the code quite a bit. This change has mixed performance effects. - The size of `TokenStream` drops from 32 bytes to 8 bytes, and there is one less case for all the match statements. - The conversion of a `TokenTree` to a `TokenStream` now requires two allocations, for the creation of a single element Lrc<Vec<_>>. (But a subsequent commit in this PR will reduce the main source of such conversions.)

2019-01-13Rollup merge of #57004 - nnethercote:TS-change-Stream, r=petrochenkovMazdak Farrokhzad-335/+141
Make `TokenStream` less recursive. `TokenStream` is currently recursive in *two* ways: - the `TokenTree` variant contains a `ThinTokenStream`, which can contain a `TokenStream`; - the `TokenStream` variant contains a `Vec<TokenStream>`. The latter is not necessary and causes significant complexity. This commit replaces it with the simpler `Vec<(TokenTree, IsJoint)>`. This reduces complexity significantly. In particular, `StreamCursor` is eliminated, and `Cursor` becomes much simpler, consisting now of just a `TokenStream` and an index. The commit also removes the `Extend` impl for `TokenStream`, because it is only used in tests. (The commit also removes those tests.) Overall, the commit reduces the number of lines of code by almost 200.

Update the const fn tracking issue to the new metabug The new `const fn` tracking issue is #57563. We don't want to point to a closed issue in the diagnostics (or FIXMEs), so these have been updated (from the old issue, #24111). r? @Centril

r=simulacrum Change `String` to `&'static str` in `ParseResult::Failure`. This avoids 770,000 allocations when compiling the `html5ever` benchmark, reducing instruction counts by up to 2%.

Stabilize `uniform_paths` Address all the things described in https://github.com/rust-lang/rust/issues/56417. Assign visibilities to `macro_rules` items - `pub` to `macro_export`-ed macros and `pub(crate)` to non-exported macros, these visibilities determine how far these macros can be reexported with `use`. Prohibit use of reexported inert attributes and "tool modules", after renaming (e.g. `use inline as imported_inline`) their respective tools and even compiler passes won't be able to recognize and properly check them. Also turn use of uniform paths in 2015 macros into an error, I'd prefer to neither remove nor stabilize them right away because I still want to make some experiments in this area (uniform path fallback was added to 2015 macros used on 2018 edition in https://github.com/rust-lang/rust/pull/56053#issuecomment-441405140). UPDATE: The last commit also stabilizes the feature `uniform_paths`.

make `panictry!` private to libsyntax This commit completely removes usage of the `panictry!` macro from outside libsyntax. The macro causes parse errors to be fatal, so using it in libsyntax_ext caused parse failures *within* a syntax extension to be fatal, which is probably not intended. Furthermore, this commit adds spans to diagnostics emitted by empty extensions if they were missing, à la #56491.
