…haelwoerister Introduce -Z remap-cwd-prefix switch This switch remaps any absolute paths rooted under the current working directory to a new value. This includes remapping the debug info in `DW_AT_comp_dir` and `DW_AT_decl_file`. Importantly, this flag does not require passing the current working directory to the compiler, such that the command line can be run on any machine (with the same input files) and produce the same results. This is critical property for debugging compiler issues that crop up on remote machines. This is based on adetaylor's rust-lang@dbc4ae7 Major Change Proposal: rust-lang/compiler-team#450 Discussed on rust-lang#38322. Would resolve issue rust-lang#87325.
…ports, r=Amanieu Remove `cfg(doc)` from std::os module reexports to fix rustdoc linking issues Fixes rust-lang#88304. I tested it based on rust-lang#88292. Not sure if it's the best approach, but at least it makes thing a bit simpler. cc ```@jyn514```
…xpr-parse, r=nagisa
Accept `m!{ .. }.method()` and `m!{ .. }?` statements.
This PR fixes something that I keep running into when using `quote!{}.into()` in a proc macro to convert the `proc_macro2::TokenStream` to a `proc_macro::TokenStream`:
Before:
```
error: expected expression, found `.`
--> src/lib.rs:6:6
|
4 | quote! {
5 | ...
6 | }.into()
| ^ expected expression
```
After:
```
```
(No output, compiles fine.)

Context:
For expressions like `{ 1 }` and `if true { 1 } else { 2 }`, we accept them as full statements without a trailing `;`, which means the following is not accepted:
```rust
{ 1 } - 1 // error
```
since that is parsed as two statements: `{ 1 }` and `-1`. Syntactically correct, but the type of `{ 1 }` should be `()` as there is no `;`.
However, for specifically `.` and `?` after the `}`, we do [continue parsing it as an expression](https://github.com/rust-lang/rust/blob/13db8440bbbe42870bc828d4ec3e965b38670277/compiler/rustc_parse/src/parser/expr.rs#L864-L876):
```rust
{ "abc" }.len(); // ok
```
For braced macro invocations, we do not do this:
```rust
vec![1, 2, 3].len(); // ok
vec!{1, 2, 3}.len(); // error
```
(It parses `vec!{1, 2, 3}` as a full statement, and then complains about `.len()` not being a valid expression.)
This PR changes this to also look for a `.` and `?` after a braced macro invocation. We can be sure the macro is an expression and not a full statement in those cases, since no statement can start with a `.` or `?`.
… r=davidtwco Revert anon union parsing Revert PR rust-lang#84571 and rust-lang#85515, which implemented anonymous union parsing in a manner that broke the context-sensitivity for the `union` keyword and thus broke stable Rust code. Fix rust-lang#88583.
Tokenize emoji as if they were valid identifiers In the lexer, consider emojis to be valid identifiers and reject them later to avoid knock down parse errors. Partially address rust-lang#86102.
…r=estebank feat(rustc_typeck): suggest removing bad parens in `(recv.method)()` Fixes rust-lang#88803
`Wrapping<T>` has the same layout and ABI as `T`
Remove implementation of `min_align_of` intrinsic Since rust-lang#88839 `min_align_of` is lowered to AlignOf operator.
