2020-02-06Rollup merge of #68788 - Centril:unified-fn-bodies, r=petrochenkovDylan DPC-2/+2
Towards unified `fn` grammar Part of https://github.com/rust-lang/rust/pull/68728. - Syntactically, `fn` items in `extern { ... }` blocks can now have bodies (`fn foo() { ... }` as opposed to `fn foo();`). As above, we use semantic restrictions instead. - Syntactically, `fn` items in free contexts (directly in a file or a module) can now be without bodies (`fn foo();` as opposed to `fn foo() { ... }`. As above, we use semantic restrictions instead, including for non-ident parameter patterns. - We move towards unifying the `fn` front matter; this is fully realized in https://github.com/rust-lang/rust/pull/68728. r? @petrochenkov

2020-02-05parser: merge `fn` grammars wrt. bodies & headersMazdak Farrokhzad-2/+2

2020-01-31Auto merge of #68080 - varkor:declared-here, r=petrochenkovbors-5/+5
Address inconsistency in using "is" with "declared here" "is" was generally used for NLL diagnostics, but not other diagnostics. Using "is" makes the diagnostics sound more natural and readable, so it seems sensible to commit to them throughout. r? @Centril
2020-01-26rustc_span: move pretty syntax from macro_backtrace to ExpnKind::descr.Eduard-Mihai Burtescu-1/+1

2019-12-08Rollup merge of #66325 - BartMassey:master, r=joshtriplettMazdak Farrokhzad-1/+1
Change unused_labels from allow to warn Fixes #66324, making the unused_labels lint warn instead of allow by default. I'm told @rust-lang/lang will need to review this, and perhaps will want to do a crater run.
2019-11-26Bless ui tests for libcore reformatDavid Tolnay-2/+2
2019-11-25Tweak removed feature errorEsteban Küber-6/+2
2019-11-25Tweak duplicate matcher binding errorEsteban Küber-28/+12
2019-11-15Cleaned up unused labelsBart Massey-1/+1
Deleted unused labels from compiler and fixed or allowed unused labels in tests. This patch removes some gratuitous unused labels and turns off the warning for unused labels that are a necessary part of tests. This will permit setting the `unused_labels` lint to `warn`.
2019-11-14Fix ui tests with better error code usageGuillaume Gomez-0/+1
2019-11-10Make error and warning annotations mandatory in UI testsTomasz Miąsko-13/+3
This change makes error and warning annotations mandatory in UI tests. The only exception are tests that use error patterns to match compiler output and don't have any annotations.

2019-10-29Rollup merge of #65832 - tlively:emscripten-exception-handling, r=alexcrichtonTyler Mandry-1/+1
Re-enable Emscripten's exception handling support Passes LLVM codegen and Emscripten link-time flags for exception handling if and only if the panic strategy is `unwind`. Sets the default panic strategy for Emscripten targets to `unwind`. Re-enables tests that depend on unwinding support for Emscripten, including `should_panic` tests. r? @alexcrichton
2019-10-28Rollup merge of #65640 - estebank:recover-missing-semi, r=CentrilMazdak Farrokhzad-2/+2
Use heuristics to recover parsing of missing `;` - Detect `,` and `:` typos where `;` was intended. - When the next token could have been the start of a new statement, detect a missing semicolon. Fix #48160, fix #44767 (after adding note about statements).

2019-10-28Tweak unexpected token wordingEsteban Küber-1/+1
2019-10-27Point at local similarly named element and tweak references to variantsEsteban Küber-2/+7
Point at the span for the definition of ADTs internal to the current crate. Look at the leading char of the ident to determine whether we're expecting a likely fn or any of a fn, a tuple struct or a tuple variant. Turn fn `add_typo_suggestion` into a `Resolver` method.
2019-10-25Re-enable Emscripten's exception handling supportThomas Lively-1/+1
Passes LLVM codegen and Emscripten link-time flags for exception handling if and only if the panic strategy is `unwind`. Sets the default panic strategy for Emscripten targets to `unwind`. Re-enables tests that depend on unwinding support for Emscripten, including `should_panic` tests.
2019-10-24Increase spacing for suggestions in diagnosticsEsteban Küber-0/+11
Make the spacing between the code snippet and verbose structured suggestions consistent with note and help messages.
2019-10-16Upgrade Emscripten targets to use upstream LLVM backendThomas Lively-0/+2
- Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

2019-10-05Revert "Auto merge of #63649 - tlively:emscripten-upstream-upgrade, ↵Tyler Mandry-2/+0
r=alexcrichton" This reverts commit 7870050796e5904a0fc85ecbe6fa6dde1cfe0c91, reversing changes made to 2e7244807a7878f6eca3eb7d97ae9b413aa49014.
2019-10-04Upgrade Emscripten targets to use upstream LLVM backendThomas Lively-0/+2
- Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the incorrect wasm32 C call ABI with the old asmjs version, which is correct for both wasm32 and JS. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Temporarily makes Emscripten targets use panic=abort by default because supporting unwinding will require an LLVM patch.
