In CI, the receiver thread can be descheduled for a surprisingly long time, so there's no guarantee that a timeout actually occurs.

Avoid an ICE for: struct A; impl A<B> {} The compiler no longer panics and can proceed to emit existing diagnostics. Adds `tests/ui/missing/undeclared-generic-parameter.rs`. Signed-off-by: Usman Akinyemi <usmanakinyemi202@gmail.com>

Now that the tracking issue has been opened, point to it.

…lacrum Remove a flaky `got_timeout` assert from two channel tests In CI, the receiver thread can be descheduled for a surprisingly long time, so there's no guarantee that a timeout actually occurs. One of these tests actually failed in rust-lang#153387 (comment). Earlier failures: - rust-lang#150365 (comment) - rust-lang#147775 (comment) --- - Prior art: rust-lang#152878

@bors

… r=sayantn add neon load/store assembly test I'm adding this test because it was requested for the beta backport of rust-lang#153336. We'd like to test this with Miri, but currently there is no load/store pair that roundtrips because one or the other still uses the platform-specific intrinsics. r? sayantn I believe test-various runs some arm and android tests? @bors try job=test-various

…ulacrum Add new alias for Guillaume Gomez email address I'm switching to a new email account and slowly updating all references to the old one.

…tebank diagnostics: avoid ICE for undeclared generic parameter in impl Avoid an ICE for: struct A; impl A<B> {} The compiler no longer panics and can proceed to emit existing diagnostics. Adds `tests/ui/missing/undeclared-generic-parameter.rs`. Fixes rust-lang#154165 and introduced by rust-lang#152913

…o_the_tracking_issue, r=JonathanBrouwer Update the tracking issue for #[diagnostic::on_move] PR rust-lang#150935 has been merged and then I have opened the tracking issue (whoops ?). So this update `compiler/rustc_feature/src/unstable.rs` to point to the right tracking issue. This is related to the tracking issue rust-lang#154181
