2020-02-18Rollup merge of #69194 - Centril:assoc-extern-fuse, r=petrochenkovMazdak Farrokhzad-1/+1
parse: fuse associated and extern items up to defaultness Language changes: - The grammar of extern `type` aliases is unified with associated ones, and becomes: ```rust TypeItem = "type" ident generics {":" bounds}? where_clause {"=" type}? ";" ; ``` Semantic restrictions (`ast_validation`) are added to forbid any parameters in `generics`, any bounds in `bounds`, and any predicates in `where_clause`, as well as the presence of a type expression (`= u8`). (Work still remains to fuse this with free `type` aliases, but this can be done later.) - The grammar of constants and static items (free, associated, and extern) now permits the absence of an expression, and becomes: ```rust GlobalItem = {"const" {ident | "_"} | "static" "mut"? ident} {"=" expr}? ";" ; ``` - A semantic restriction is added to enforce the presence of the expression (the body). - A semantic restriction is added to reject `const _` in associated contexts. Together, these changes allow us to fuse the grammar of associated items and extern items up to `default`ness which is the main goal of the PR. ----------------------- We are now very close to fully fusing the entirely of item parsing and their ASTs. To progress further, we must make a decision: should we parse e.g. `default use foo::bar;` and whatnot? Accepting that is likely easiest from a parsing perspective, as it does not require using look-ahead, but it is perhaps not too onerous to only accept it for `fn`s (and all their various qualifiers), `const`s, `static`s, and `type`s. r? @petrochenkov

[experiment] Support linking from a .rlink file Flag `-Z no-link` was previously introduced, which allows creating an `.rlink` file to perform compilation without linking. This change enables linking from an `.rlink` file. Part of Issue #64191
2020-02-11Rollup merge of #66498 - bjorn3:less_feature_flags, r=Dylan-DPCDylan DPC-2/+0
Remove unused feature gates I think many of the remaining unstable things can be easily be replaced with stable things. I have kept the `#![feature(nll)]` even though it is only necessary in `libstd`, to make regressions of it harder.

Use BufWriter for emitting MIR I noticed that `--emit=mir` takes long time on a large crate. https://github.com/rust-lang/rust/pull/64344 seem to have fixed `-Zdump-mir`, but not `--emit=mir`.

This commit reduces the size of `Nonterminal` from a whopping 240 bytes to 72 bytes (on x86-64), which gets it below the `memcpy` threshold. It also removes some impedance mismatches with `Annotatable`, which already uses `P` for these variants.
