2019-11-15Rollup merge of #66415 - tmandry:force-test-in-process, r=alexcrichtonMazdak Farrokhzad-1/+2
Add --force-run-in-process unstable option to libtest When running tests with `-Zpanic_abort_tests`, it's sometimes desirable to fall back to the old behavior of only running tests in-process. This comes in handy if the system process launcher is unavailable, or the test code somehow expects all tests to be run in the same process. For example, in Fuchsia we have unit tests that actually test the process launcher itself, in which case we can't use the process launcher to run the tests :). r? @alexcrichton cc @cramertj,@petrhosek

2019-11-10Auto merge of #65324 - Centril:organize-syntax, r=petrochenkovbors-11/+12
Split libsyntax apart In this PR the general idea is to separate the AST, parser, and friends by a more data / logic structure (tho not fully realized!) by separating out the parser and macro expansion code from libsyntax. Specifically have now three crates instead of one (libsyntax): - libsyntax: - concrete syntax tree (`syntax::ast`) - definition of tokens and token-streams (`syntax::{token, tokenstream}`) -- used by `syntax::ast` - visitors (`syntax::visit`, `syntax::mut_visit`) - shared definitions between `libsyntax_expand` - feature gating (`syntax::feature_gate`) -- we could possibly move this out to its own crater later. - attribute and meta item utilities, including used-marking (`syntax::attr`) - pretty printer (`syntax::print`) -- this should possibly be moved out later. For now I've reduced down the dependencies to a single essential one which could be broken via `ParseSess`. This entails that e.g. `Debug` impls for `Path` cannot reference the pretty printer. - definition of `ParseSess` (`syntax::sess`) -- this is used by `syntax::{attr, print, feature_gate}` and is a common definition used by the parser and other things like librustc. - the `syntax::source_map` -- this includes definitions used by `syntax::ast` and other things but could ostensibly be moved `syntax_pos` since that is more related to this module. - a smattering of misc utilities not sufficiently important to itemize -- some of these could be moved to where they are used (often a single place) but I wanted to limit the scope of this PR. - librustc_parse: - parser (`rustc_parse::parser`) -- reading a file and such are defined in the crate root tho. - lexer (`rustc_parse::lexer`) - validation of meta grammar (post-expansion) in (`rustc_parse::validate_attr`) - libsyntax_expand -- this defines the infra for macro expansion and conditional compilation but this is not libsyntax_ext; we might want to merge them later but currently libsyntax_expand is depended on by librustc_metadata which libsyntax_ext is not. - conditional compilation (`syntax_expand::config`) -- moved from `syntax::config` to here - the bulk of this crate is made up of the old `syntax::ext` r? @estebank

2019-11-09Rollup merge of #66134 - estebank:unknown-formatting-trait, r=nikomatsakisMazdak Farrokhzad-33/+55
Point at formatting descriptor string when it is invalid When a formatting string contains an invalid descriptor, point at it instead of the argument: ``` error: unknown format trait `foo` --> $DIR/ifmt-bad-arg.rs:86:17 | LL | println!("{:foo}", 1); | ^^^ | = note: the only appropriate formatting traits are: - ``, which uses the `Display` trait - `?`, which uses the `Debug` trait - `e`, which uses the `LowerExp` trait - `E`, which uses the `UpperExp` trait - `o`, which uses the `Octal` trait - `p`, which uses the `Pointer` trait - `b`, which uses the `Binary` trait - `x`, which uses the `LowerHex` trait - `X`, which uses the `UpperHex` trait ```

2019-11-07syntax: use distinct FloatTy from rustc_target.Mazdak Farrokhzad-2/+1
We also sever syntax's dependency on rustc_target as a result. This should slightly improve pipe-lining. Moreover, some cleanup is done in related code.

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-6/+8
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.

This kind of thing just makes the code harder to read.
