…eports and remove the feature gate that silenced the lint
This allows the standard library to be compiled even with `download-rustc` enabled. Which means it's no longer a requirement to compile `rustc` in order to compile `std`. Signed-off-by: onur-ozkan <work@onurozkan.dev>

…d" assertion ICE See <rust-lang#128622>.
PR rust-lang#128581 introduced an assertion that all builtin attributes are actually checked via `CheckAttrVisitor` and aren't accidentally usable on completely unrelated HIR nodes. Unfortunately, the check had correctness problems. The match on attribute path segments looked like ```rust,ignore [sym::should_panic] => /* check is implemented */ match BUILTIN_ATTRIBUTE_MAP.get(name) { // checked below Some(BuiltinAttribute { type_: AttributeType::CrateLevel, .. }) => {} Some(_) => { if !name.as_str().starts_with("rustc_") { span_bug!( attr.span, "builtin attribute {name:?} not handled by `CheckAttrVisitor`" ) } } None => (), } ``` However, it failed to account for edge cases such as an attribute whose: 1. path segments *starts* with a builtin attribute such as `should_panic` 2. which does not start with `rustc_`, and 3. is also an `AttributeType::Normal` attribute upon registration with the builtin attribute map These conditions when all satisfied cause the span bug to be issued for e.g. `#[should_panic::skip]` because the `[sym::should_panic]` arm is not matched (since it's `[sym::should_panic, sym::skip]`). See <rust-lang#128622>.
…t, r=compiler-errors turn `invalid_type_param_default` into a `FutureReleaseErrorReportInDeps` `````@rust-lang/types````` I assume the plan is still to disallow this? It has been a future-compat lint for a long time, seems ripe to go for hard error. However, turns out that outright removing it right now would lead to [tons of crater regressions](rust-lang#127655 (comment)), so for now this PR just makes this future-compat lint show up in cargo's reports, so people are warned when they use a dependency that is affected by this. Fixes rust-lang#27336 by removing the feature gate (so there's no way to silence the lint even on nightly) CC rust-lang#36887
…ct_with_derive, r=nnethercote built-in derive: remove BYTE_SLICE_IN_PACKED_STRUCT_WITH_DERIVE hack and lint Fixes rust-lang#107457 by turning the lint into a hard error. The lint has been shown in future breakage reports since Rust 1.69 (released in April 2023). Let's see (via crater) if enough time has passed since rust-lang#104429, and unicode-org/icu4x#2834 has propagated far enough to let us make this a hard error. Cc ``@nnethercote`` ``@Manishearth``
…k-Simulacrum force compiling std from source if modified This allows the standard library to be compiled even with `download-rustc` enabled. Which means it's no longer a requirement to compile `rustc` in order to compile `std`. Ref. rust-lang#127322 (comment). Blocker for rust-lang#122709.
Implement cursors for `BTreeSet` Tracking issue: rust-lang#107540 This is a straightforward wrapping of the map API, except that map's `CursorMut` does not make sense, because there is no value to mutate. Hence, map's `CursorMutKey` is wrapped here as just `CursorMut`, since it's unambiguous for sets and we don't normally speak of "keys". On the other hand, I can see some potential for confusion with `CursorMut` meaning different things in each module. I'm happy to take suggestions to improve that. r? ````@Amanieu````
…lacrum Add test for updating enum discriminant through pointer Closes rust-lang#122600
…cote Do not fire unhandled attribute assertion on multi-segment `AttributeType::Normal` attributes with builtin attribute as first segment ### The Problem In rust-lang#128581 I introduced an assertion to check that all builtin attributes are actually checked via `CheckAttrVisitor` and aren't accidentally usable on completely unrelated HIR nodes. Unfortunately, the assertion had correctness problems as revealed in rust-lang#128622. The match on attribute path segments looked like ```rs,ignore // Normal handler [sym::should_panic] => /* check is implemented */ // Fallback handler [name, ..] => match BUILTIN_ATTRIBUTE_MAP.get(name) { // checked below Some(BuiltinAttribute { type_: AttributeType::CrateLevel, .. }) => {} Some(_) => { if !name.as_str().starts_with("rustc_") { span_bug!( attr.span, "builtin attribute {name:?} not handled by `CheckAttrVisitor`" ) } } None => (), } ``` However, it failed to account for edge cases such as an attribute whose: 1. path segments *starts* with a segment matching the name of a builtin attribute such as `should_panic`, and 2. the first segment's symbol does not start with `rustc_`, and 3. the matched builtin attribute is also of `AttributeType::Normal` attribute type upon registration with the builtin attribute map. These conditions when all satisfied cause the span bug to be issued for e.g. `#[should_panic::skip]` because the `[sym::should_panic]` arm is not matched (since it's `[sym::should_panic, sym::skip]`). ### Proposed Solution This PR tries to remedy that by adjusting all normal/specific handlers to not match exactly on a single segment, but instead match a prefix segment. i.e. ```rs,ignore // Normal handler, notice the `, ..` rest pattern [sym::should_panic, ..] => /* check is implemented */ // Fallback handler [name, ..] => match BUILTIN_ATTRIBUTE_MAP.get(name) { // checked below Some(BuiltinAttribute { type_: AttributeType::CrateLevel, .. }) => {} Some(_) => { if !name.as_str().starts_with("rustc_") { span_bug!( attr.span, "builtin attribute {name:?} not handled by `CheckAttrVisitor`" ) } } None => (), } ``` ### Review Remarks This PR contains 2 commits: 1. The first commit adds a regression test. This will ICE without the `CheckAttrVisitor` changes. 2. The second commit adjusts `CheckAttrVisitor` assertion logic. Once this commit is applied, the test should no longer ICE and produce the expected bless stderr. Fixes rust-lang#128622. r? ``@nnethercote`` (since you reviewed rust-lang#128581)
