…les.

It's tautological, and Rust-specific Jargon. This changes various Option/Result methods to consistently describe unwrapping behavior using the words "return", "contain", "consume". It also renames the closure argument of `Return::unwrap_or_else` to `default` to be consistent with `Option`.

This reduces the number of `associated_item` queries done here.

Quickly skip impls that do not define any items with the same name

Implement proper C ABI lowering for RISC-V This is necessary for full RISC-V psABI compliance when passing argument across C FFI boundary. cc @lenary

@michaelwoerister

…agisa rustc_codegen_llvm: always set AlwaysPreserve on all debuginfo variables Making this depend on the optimization level appears to have been a copy-paste mistake (other LLVM functions called in this module also take a `bool` argument, but there it means something unrelated). Also see rust-lang#8855 (comment). I don't believe we have any reason to let LLVM omit user variables from DWARF, and we were already setting this to `true` when LLVM *could* optimize them away, so this PR should have no effect anyway. r? @michaelwoerister or @nagisa cc @rkruppe @nikomatsakis

…=petrochenkov Speed up the inherent impl overlap check This gives a ~7% improvement in compile times for the stm32f0(x2) crate. Also addresses @eddyb's comment in rust-lang#68837 (comment).

Pretty-print generic params and where clauses on associated types closes rust-lang#67509

Don't use the word "unwrap" to describe "unwrap" methods It's tautological, and "unwrap" is essentially Rust-specific jargon. I was teaching a newbie some Rust, and doing the usual hand-waving about error handling using unwrap. They asked what 'unwrap' means. I said look it up in the docs. The docs read (paraphrased) "unwrap unwraps". I was embarrassed. This changes all the Option/Result functions with unwrapping behavior to use a variation on a single description: > "Returns the contained `Some/Ok` value [or ...]." It also renames the closure of `Result::unwrap_or_else` to `default` for consistency with `Option`, and perhaps makes a few other small tweaks. Previous: rust-lang#68849
