I find the code easier to read if the values in `config` are all used directly, rather than a mix of `config` values and local variables. It will also faciliate some of the following commits. Also, use `config.bitcode_needed()` in one place.
Because the `(true, true)` combination isn't valid.
This adds a missing `!config.obj_is_bitcode` condition to two places that should have it. As a result, when `obj_is_bitcode` and `no_integrated_as` are both true, the compiler will no longer unnecessarily emit asm, convert it to an object file, and then overwrite that object file with bitcode.
Previously, we threw away the `Span` associated with a definition's identifier when we encoded crate metadata, causing us to lose location and hygiene information. We now store the identifier's `Span` in the crate metadata. When we decode items from the metadata, we combine the name and span back into an `Ident`. This improves the output of several tests, which previously had messages suppressed due to dummy spans. This is a prerequisite for rust-lang#68686, since throwing away a `Span` means that we lose hygiene information.
Make the `type_of` return a generic type for generators Fixes rust-lang#67651. r? @nikomatsakis
…ltin_traits, r=Dylan-DPC Fix sequence of Type and Trait in optin-builtin-traits in Unstable Book A simple fix in docs - the sequence of words in basic example of negative trait implementation was reversed.
…atthewjasper Make `needs_drop` less pessimistic on generators Generators only have non-trivial drop logic when they may store (in upvars or across yields) a type that does. This prevents generation of some unnecessary MIR in simple generators. There might be some impact on compile times, but this is probably limited in real-world applications. ~~This builds off of rust-lang#69814 since that contains some fixes that are made relevant by *this* PR (see rust-lang#69814 (comment) (this has been merged)
…t, r=petrochenkov Store idents for `DefPathData` into crate metadata Previously, we threw away the `Span` associated with a definition's identifier when we encoded crate metadata, causing us to lose location and hygiene information. We now store the identifier's `Span` in a side table, which gets encoded into the crate metadata. When we decode items from the metadata, we combine the name and span back into an `Ident`. This improves the output of several tests, which previously had messages suppressed due to dummy spans. This is a prerequisite for rust-lang#68686, since throwing away a `Span` means that we lose hygiene information.
…omatsakis traits/fulfill: allow `stalled_on` to track `ty::Const::Infer(_)` (unused yet). This PR addresses the representation side of rust-lang#70180, but only *actually collects* `ty::Infer`s via `Ty::walk` into `stalled_on` (collecting `ty::ConstKind::Infer`s requires rust-lang#70164). However, it should be enough to handle rust-lang#70107's needs (WF obligations are stalled only on the outermost type/const being an inference variable, no `walk`-ing is involved). This is my second attempt, see rust-lang#70181 for the previous one, which unacceptably regressed perf. r? @nikomatsakis cc @nnethercote
Use Reveal::All in MIR optimizations Resolves some code review feedback in rust-lang#67662. Fixes rust-lang#68855 r? @eddyb
…r=eddyb correctly handle const params in type_of extends rust-lang#70223, retry of rust-lang#70276 fixes rust-lang#70273 r? @eddyb cc @varkor
Refactor `codegen` `codegen` in `src/librustc_codegen_llvm/back/write.rs` is long and has complex control flow. These commits refactor it and make it easier to understand.
