2020-07-24Rollup merge of #74572 - Mark-Simulacrum:unify-rustc-depr, r=petrochenkovYuki Okushi-111/+55
Internally unify rustc_deprecated and deprecated This PR intentionally tries to be "featureless" in that the behavior is not altered for either attribute, though it more clearly exposes cases where that is the case in the code.

2020-07-20Migrate rustc_depr uses to use deprecation attributeMark Rousskov-52/+2
This should not be a change in behavior.
2020-07-20rustc_depr no longer needs to be connected to stabilityMark Rousskov-16/+0
We can deprecate non-stable/unstable items.

2020-07-15Add and use more static symbols.Nicholas Nethercote-4/+4
Note that the output of `unpretty-debug.stdout` has changed. In that test the hash values are normalized from a symbol numbers to small numbers like "0#0" and "0#1". The increase in the number of static symbols must have caused the original numbers to contain more digits, resulting in different pretty-printing prior to normalization.

2020-05-08Rollup merge of #72017 - ctaggart:wasm2, r=ecstatic-morseDylan DPC-0/+4
Work around ICEs during cross-compilation for target, ast, & attr This applies the fix for #72003 to work around #56935 to three more libraries. With these additional fixes, I'm able to use rustfmt_lib from wasm (https://github.com/rust-lang/rustfmt/issues/4132#issuecomment-616587989), which was my goal. To get it working locally and to test, I copied the `.cargo/registry/src` and applied the fix and replaced the reference in my project: ``` toml [replace] "rustc-ap-rustc_span:656.0.0" = { path = "../rustc-ap-rustc_span" } "rustc-ap-rustc_target:656.0.0" = { path = "../rustc-ap-rustc_target" } "rustc-ap-rustc_ast:656.0.0" = { path = "../rustc-ap-rustc_ast" } "rustc-ap-rustc_attr:656.0.0" = { path = "../rustc-ap-rustc_attr" } ```

2020-02-11Auto merge of #68491 - pnkfelix:hide-niches-under-unsafe-cell, r=olibors-0/+2
Hide niches under UnsafeCell Hide any niche of T from type-construction context of `UnsafeCell<T>`. Fix #68303 Fix #68206

2020-02-11Invert control in struct_lint_level.jumbatm-2/+2
Caller now passes in a `decorate` function, which is only run if the lint is allowed.
2020-02-10Add `#[repr(no_niche)]`.Felix S. Klock II-0/+2
This repr-hint makes a struct/enum hide any niche within from its surrounding type-construction context. It is meant (at least initially) as an implementation detail for resolving issue 68303. We will not stabilize the repr-hint unless someone finds motivation for doing so. (So, declaration of `no_niche` feature lives in section of file where other internal implementation details are grouped, and deliberately leaves out the tracking issue number.) incorporated review feedback, and fixed post-rebase.

2020-02-01Move builtin attribute logic to new rustc_attr crate.Mazdak Farrokhzad-0/+1082
For now, this is all the crate contains, but more attribute logic & types will be moved there over time.
