2019-11-14Update to use new librustc_error_codes libraryGuillaume Gomez-0/+2
2019-11-07syntax::parser::token -> syntax::tokenMazdak Farrokhzad-1/+1
2019-10-16move syntax::ext to new crate syntax_expandMazdak Farrokhzad-1/+1
2019-09-26Rename `Expr.node` to `Expr.kind`varkor-1/+1
For both `ast::Expr` and `hir::Expr`.
2019-09-15Remove `with_legacy_ctxt`Matthew Jasper-1/+1
2019-09-03use TokenStream rather than &[TokenTree] for built-in macrosAleksey Kladov-14/+10
That way, we don't loose the jointness info
2019-08-23Audit uses of `apply_mark` in built-in macrosVadim Petrochenkov-1/+1
Replace them with equivalents of `Span::{def_site,call_site}` from proc macro API. The new API is much less error prone and doesn't rely on macros having default transparency.
2019-08-17Remove SyntaxContext from {ast, hir}::{GlobalAsm, InlineAsm}Matthew Jasper-2/+1
We now store it in the `Span` of the expression or item.
2019-08-13syntax: Remove `DummyResult::expn_only`Vadim Petrochenkov-2/+2
2019-07-07syntax: Migrate built-in macros to the regular stability checkingVadim Petrochenkov-9/+0
2019-06-06syntax: Use `Token` in `Parser`Vadim Petrochenkov-1/+1
2019-06-06syntax: Use `Token` in `TokenTree::Token`Vadim Petrochenkov-3/+4
2019-05-27Avoid unnecessary internings.Nicholas Nethercote-2/+2
Most involving `Symbol::intern` on string literals.
2019-05-24Tweak macro parse errors when reaching EOF during macro call parseEsteban Küber-1/+5
- Add detail on origin of current parser when reaching EOF and stop saying "found <eof>" and point at the end of macro calls - Handle empty `cfg_attr` attribute - Reword empty `derive` attribute error
2019-05-13Remove the equality operation between `Symbol` and strings.Nicholas Nethercote-4/+4
And also the equality between `Path` and strings, because `Path` is made up of `Symbol`s.
2019-05-13Pass a `Symbol` to `check_name`, `emit_feature_err`, and related functions.Nicholas Nethercote-2/+2
2019-02-13Rename rustc_errors dependency in rust 2018 cratesTaiki Endo-1/+1
2019-02-04libsyntax_ext => 2018Taiki Endo-5/+6
2019-01-02make `panictry!` private to libsyntaxAndy Russell-45/+71
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.
2018-12-27Make sure feature gate errors are recoverableVadim Petrochenkov-1/+0

2018-05-15Add missing error codes in libsyntax-ext asmGuillaume Gomez-3/+6
2018-04-14Add error codes for libsyntax_extGuillaume Gomez-2/+14
2018-02-05Make inline assembly volatile if it has no outputs. Fixes #46026John Kåre Alsaker-0/+6
2017-08-15use field init shorthand EVERYWHEREZack M. Davis-8/+8
Like #43008 (f668999), but _much more aggressive_.
2017-03-29Merge `ExpnId` and `SyntaxContext`.Jeffrey Seyfried-11/+1
2017-03-03Integrate `TokenStream`.Jeffrey Seyfried-1/+1
2016-11-21Use `Symbol` instead of `InternedString` in the AST, HIR, and various other ↵Jeffrey Seyfried-10/+11
places.
2016-11-20Move `syntax::util::interner` -> `syntax::symbol`, cleanup.Jeffrey Seyfried-5/+5
2016-11-03Make `ast::ExprKind` smaller.Jeffrey Seyfried-2/+2
2016-10-29Move `CrateConfig` from `Crate` to `ParseSess`.Jeffrey Seyfried-1/+1
2016-10-19Rollup merge of #37161 - nnethercote:no-cfg-cloning, r=nrcEduard-Mihai Burtescu-1/+1
Avoid many CrateConfig clones. This commit changes `ExtCtx::cfg()` so it returns a `CrateConfig` reference instead of a clone. As a result, it also changes all of the `cfg()` callsites to explicitly clone... except one, because the commit also changes `macro_parser::parse()` to take `&CrateConfig`. This is good, because that function can be hot, and `CrateConfig` is expensive to clone. This change almost halves the number of heap allocations done by rustc for `html5ever` in rustc-benchmarks suite, which makes compilation 1.20x faster. r? @nrc

2016-10-05Rename Parser::last_span as prev_span.Nicholas Nethercote-6/+6
This is a [breaking-change] for libsyntax.

2016-07-06Correct inline assembly clobber formatting.CensoredUsername-0/+3
Fixes the formatting for inline assembly clobbers used in the book. As this causes llvm to silently ignore the clobber an error is also added to catch cases in which the wrong formatting was used. Additionally a test case is added to confirm that this error works.
2016-06-26Rollup merge of #34339 - jseyfried:thin_vec, r=petrochenkov,ManishearthJeffrey Seyfried-1/+1
Generalize and abstract `ThinAttributes` to `ThinVec<Attribute>`.
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-3/+4
syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).
2016-06-23Move errors from libsyntax to its own crateJonathan Turner-1/+1
