2020-08-03Auto merge of #74969 - nnethercote:rm-GCX_PTR, r=Mark-Simulacrumbors-79/+36
Remove `GCX_PTR`. We store an `ImplicitCtxt` pointer in a thread-local value (TLV). This allows implicit access to a `GlobalCtxt` and some other things. We also store a `GlobalCtxt` pointer in `GCX_PTR`. This is always the same `GlobalCtxt` as the one within the `ImplicitCtxt` pointer in TLV. `GCX_PTR` is only used in the parallel compiler's `handle_deadlock()` function. This commit does the following. - It removes `GCX_PTR`. - It also adds `ImplicitCtxt::new()`, which constructs an `ImplicitCtxt` from a `GlobalCtxt`. `ImplicitCtxt::new()` + `tls::enter_context()` is now equivalent to the old `tls::enter_global()`. - Makes `tls::get_tlv()` public for the parallel compiler, because it's now used in `handle_deadlock()`. r? @petrochenkov
2020-08-02Auto merge of #74948 - lzutao:stalize-result-as-deref, r=dtolnaybors-192/+14
Stabilize `Result::as_deref` and `as_deref_mut` FCP completed in https://github.com/rust-lang/rust/issues/50264#issuecomment-645681400. This PR stabilizes two new APIs for `std::result::Result`: ```rust fn as_deref(&self) -> Result<&T::Target, &E> where T: Deref; fn as_deref_mut(&mut self) -> Result<&mut T::Target, &mut E> where T: DerefMut; ``` This PR also removes two rarely used unstable APIs from `Result`: ```rust fn as_deref_err(&self) -> Result<&T, &E::Target> where E: Deref; fn as_deref_mut_err(&mut self) -> Result<&mut T, &mut E::Target> where E: DerefMut; ``` Closes #50264

compiletest: Support ignoring tests requiring missing LLVM components This PR implements a more principled solution to the problem described in https://github.com/rust-lang/rust/pull/66084. Builds of LLVM backends take a lot of time and disk space. So it usually makes sense to build rustc with ```toml [llvm] targets = "X86" experimental-targets = "" ``` unless you are working on some target-specific tasks. A few tests, however, require non-x86 backends to be built. A new test directive `// needs-llvm-components: component1 component2 component3` makes such tests to be automatically ignored if one of the listed components is missing in the provided LLVM (this is determined through `llvm-config --components`). As a result, the test suite now fully passes with LLVM built only with the x86 backend. The component list in this case is ``` aggressiveinstcombine all all-targets analysis asmparser asmprinter binaryformat bitreader bitstreamreader bitwriter cfguard codegen core coroutines coverage debuginfocodeview debuginfodwarf debuginfogsym debuginfomsf debuginfopdb demangle dlltooldriver dwarflinker engine executionengine frontendopenmp fuzzmutate globalisel instcombine instrumentation interpreter ipo irreader jitlink libdriver lineeditor linker lto mc mca mcdisassembler mcjit mcparser mirparser native nativecodegen objcarcopts object objectyaml option orcerror orcjit passes profiledata remarks runtimedyld scalaropts selectiondag support symbolize tablegen target textapi transformutils vectorize windowsmanifest x86 x86asmparser x86codegen x86desc x86disassembler x86info x86utils xray ``` (With the default target list it's much larger.) ``` aarch64 aarch64asmparser aarch64codegen aarch64desc aarch64disassembler aarch64info aarch64utils aggressiveinstcombine all all-targets analysis arm armasmparser armcodegen armdesc armdisassembler arminfo armutils asmparser asmprinter avr avrasmparser avrcodegen avrdesc avrdisassembler avrinfo binaryformat bitreader bitstreamreader bitwriter cfguard codegen core coroutines coverage debuginfocodeview debuginfodwarf debuginfogsym debuginfomsf debuginfopdb demangle dlltooldriver dwarflinker engine executionengine frontendopenmp fuzzmutate globalisel hexagon hexagonasmparser hexagoncodegen hexagondesc hexagondisassembler hexagoninfo instcombine instrumentation interpreter ipo irreader jitlink libdriver lineeditor linker lto mc mca mcdisassembler mcjit mcparser mips mipsasmparser mipscodegen mipsdesc mipsdisassembler mipsinfo mirparser msp430 msp430asmparser msp430codegen msp430desc msp430disassembler msp430info native nativecodegen nvptx nvptxcodegen nvptxdesc nvptxinfo objcarcopts object objectyaml option orcerror orcjit passes powerpc powerpcasmparser powerpccodegen powerpcdesc powerpcdisassembler powerpcinfo profiledata remarks riscv riscvasmparser riscvcodegen riscvdesc riscvdisassembler riscvinfo riscvutils runtimedyld scalaropts selectiondag sparc sparcasmparser sparccodegen sparcdesc sparcdisassembler sparcinfo support symbolize systemz systemzasmparser systemzcodegen systemzdesc systemzdisassembler systemzinfo tablegen target textapi transformutils vectorize webassembly webassemblyasmparser webassemblycodegen webassemblydesc webassemblydisassembler webassemblyinfo windowsmanifest x86 x86asmparser x86codegen x86desc x86disassembler x86info x86utils xray ``` https://github.com/rust-lang/rust/pull/66084 is also reverted now. r? @Mark-Simulacrum

r=petrochenkov pprust: adjust mixed comment printing and add regression test for #74745 Fixes #74745. This PR adds a regression test for #74745. While a `ignore-tidy-trailing-lines` header is required, this doesn't stop the test from reproducing, so long as there is no newline at the end of the file. However, adding the header comments made the test fail due to a bug in pprust - so this PR also adjusts the pretty printing of mixed comments so that the initial zero-break isn't emitted at the beginning of the line. Through this, the `block-comment-wchar` test can have the `pp-exact` file removed, as it no longer converges from pretty printing of the source.

Introduce NonterminalKind for more type-safe mbe parsing It encapsulate the (part of) the interface between the parser and macro by example (macro_rules) parser. The second bit is somewhat more general `parse_ast_fragment`, which is the reason why we keep some `parse_xxx` functions as public.

2020-08-03Rollup merge of #74762 - ssomers:btree_no_root_in_remove_kv_tracking, ↵Yuki Okushi-52/+405
r=Mark-Simulacrum BTreeMap::drain_filter should not touch the root during iteration Although Miri doesn't point it out, I believe there is undefined behaviour using `drain_filter` when draining the 11th-last element from a tree that was larger. When this happens, the last remaining child nodes are merged, the root becomes empty and is popped from the tree. That last step establishes a mutable reference to the node elected root and writes a pointer in `node::Root`, while iteration continues to visit the same node. This is mostly code from #74437, slightly adapted.
