This makes `rustc` support `@path` arguments on the command line. The `path` is opened and the file is interpreted as new command line options which are logically inserted at that point in the command-line. The options in the file are one per line. The file is UTF-8 encoded, and may have either Unix or Windows line endings. It does not support recursive use of `@path`. This is useful for very large command lines, or when command-lines are being generated into files by other tooling.
It was getting a bit awkward.
It already imlements the right behaviour, and it saves us implementing the state machine.

This is needed to permit us building core_arch which is a submodule dep (so we can't snap it to the new beta compiler).
Add lint for excess trailing semicolons Closes rust-lang#60876. A caveat (not necessarily a negative, but something to consider) with this implementation is that excess semicolons after return/continue/break now also cause an 'unreachable statement' warning. For the following example: ``` fn main() { extra_semis(); } fn extra_semis() -> i32 { let mut sum = 0;;; for i in 0..10 { if i == 5 { continue;; } else if i == 9 { break;; } else { sum += i;; } } return sum;; } ``` The output is: ``` warning: unnecessary trailing semicolons --> src/main.rs:5:21 | 5 | let mut sum = 0;;; | ^^ help: remove these semicolons | = note: `#[warn(redundant_semicolon)]` on by default warning: unnecessary trailing semicolon --> src/main.rs:8:22 | 8 | continue;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:10:19 | 10 | break;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:12:22 | 12 | sum += i;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:15:16 | 15 | return sum;; | ^ help: remove this semicolon warning: unreachable statement --> src/main.rs:8:22 | 8 | continue;; | ^ | = note: `#[warn(unreachable_code)]` on by default warning: unreachable statement --> src/main.rs:10:19 | 10 | break;; | ^ warning: unreachable statement --> src/main.rs:15:16 | 15 | return sum;; | ^ ```
Miri: Check that a ptr is aligned and inbounds already when evaluating `*` This syncs Miri with what the Nomicon and the Reference say, and resolves rust-lang/miri#447. Also this would not have worked without rust-lang#62982 due to new cycles. ;) r? @oli-obk
rustc: implement argsfiles for command line Many tools, such as gcc and gnu-ld, support "args files" - that is, being able to specify @file on the command line. This causes `file` to be opened and parsed for command line options. They're separated with whitespace; whitespace can be quoted with double or single quotes, and everything can be \\-escaped. Args files may recursively include other args files via `@file2`. See https://sourceware.org/binutils/docs/ld/Options.html#Options for the documentation of gnu-ld's @file parameters. This is useful for very large command lines, or when command lines are being generated into files by other tooling.
…chenkov libsyntax: cleanup and refactor `pat.rs` A smaller refactoring & cleanup of `pat.rs` (best read commit by commit). r? @petrochenkov
Remove redundant `ty` fields from `mir::Constant` and `hair::pattern::PatternRange`. Fixes rust-lang#56137. As a side-effect, associated const literals have the correct type now, which should make things easier for rust-lang#61041. r? @oli-obk / @matthewjasper cc @davidtwco @varkor
Point at the right enclosing scope when using `await` in non-async fn Fix rust-lang#63398.
syntax: Remove `DummyResult::expr_only` The effect is that if a built-in macro both returns an erroneous AST fragment and is used in unexpected position, then the incorrect position error won't be reported. This combination of two errors should be rare and isn't worth an extra field that makes people ask questions in comments. (There wasn't even a test making sure it worked.) Addresses rust-lang#63468 (comment) r? @estebank
expand: Unimplement `MutVisitor` on `MacroExpander` Each call to `fully_expand_fragment` is something unique, interesting, and requiring attention. It represents a "root" of expansion and its use means that something unusual is happening, like eager expansion or expansion performed outside of the primary expansion pass. So, it shouldn't hide under a generic visitor call. Also, from all the implemented visitor methods only two were actually used. cc rust-lang#63468 (comment)

Issue #63576 |
|
It looks like the tests have some platform variations. Is there a way to wildcard/patternmatch/normalize .stderr files to ignore the variations? Otherwise I can make the tests platform specific. |

@jsgf please follow up re. questions on the PR itself. |
