Fix `rustdoc --version` when used with download-rustc

2022-11-09T08:54:51+00:00

Previously, rustdoc would unconditionally report the version that *rustc* was compiled with. That showed things like `nightly-2022-10-30`, which wasn't right, since this was a `dev` build compiled from source. Fix it by changing `rustc_driver::version` to a macro expanded at invocation time.

ssa: implement `#[collapse_debuginfo]`

2022-09-07T12:54:51+00:00

Debuginfo line information for macro invocations are collapsed by default - line information are replaced by the line of the outermost expansion site. Using `-Zdebug-macros` disables this behaviour. When the `collapse_debuginfo` feature is enabled, the default behaviour is reversed so that debuginfo is not collapsed by default. In addition, the `#[collapse_debuginfo]` attribute is available and can be applied to macro definitions which will then have their line information collapsed. Signed-off-by: David Wood

Rename `debugging_opts` to `unstable_opts`

2022-07-13T22:47:06+00:00

This is no longer used only for debugging options (e.g. `-Zoutput-width`, `-Zallow-features`). Rename it to be more clear.

Overhaul `TyS` and `Ty`.

2022-02-15T05:03:24+00:00

Specifically, change `Ty` from this: ``` pub type Ty<'tcx> = &'tcx TyS<'tcx>; ``` to this ``` pub struct Ty<'tcx>(Interned<'tcx, TyS<'tcx>>); ``` There are two benefits to this. - It's now a first class type, so we can define methods on it. This means we can move a lot of methods away from `TyS`, leaving `TyS` as a barely-used type, which is appropriate given that it's not meant to be used directly. - The uniqueness requirement is now explicit, via the `Interned` type. E.g. the pointer-based `Eq` and `Hash` comes from `Interned`, rather than via `TyS`, which wasn't obvious at all. Much of this commit is boring churn. The interesting changes are in these files: - compiler/rustc_middle/src/arena.rs - compiler/rustc_middle/src/mir/visit.rs - compiler/rustc_middle/src/ty/context.rs - compiler/rustc_middle/src/ty/mod.rs Specifically: - Most mentions of `TyS` are removed. It's very much a dumb struct now; `Ty` has all the smarts. - `TyS` now has `crate` visibility instead of `pub`. - `TyS::make_for_test` is removed in favour of the static `BOOL_TY`, which just works better with the new structure. - The `Eq`/`Ord`/`Hash` impls are removed from `TyS`. `Interned`s impls of `Eq`/`Hash` now suffice. `Ord` is now partly on `Interned` (pointer-based, for the `Equal` case) and partly on `TyS` (contents-based, for the other cases). - There are many tedious sigil adjustments, i.e. adding or removing `*` or `&`. They seem to be unavoidable.

Store a `Symbol` instead of an `Ident` in `VariantDef`/`FieldDef`

2022-01-11T15:16:22+00:00

The field is also renamed from `ident` to `name. In most cases, we don't actually need the `Span`. A new `ident` method is added to `VariantDef` and `FieldDef`, which constructs the full `Ident` using `tcx.def_ident_span()`. This method is used in the cases where we actually need an `Ident`. This makes incremental compilation properly track changes to the `Span`, without all of the invalidations caused by storing a `Span` directly via an `Ident`.
