First, the CFI type of returning `!` came up in https://github.com/rust-lang/rust/issues/159446#issuecomment-5011154213, where we found that it doesn\u0027t have the same CFI type as returning `()`, which it probably should.\n\nThen in rust-lang/rust#159935, I wanted to make sure that this does not change the CFI type of functions when `*mut c_void` appears as an argument. Luckily it does not since it\u0027s a lang item, but there\u0027s no test for this case.\n\nThus, add tests for all of these cases and a few others.\n\nAI assistance was involved with writing the test.\n"

Previously all wasm targets, without the `atomics` feature, were funneled into the `no_threads` implementation and various fallbacks in the `thread_local` module. The upcoming `wasm32-wasip3` target, however, will actually have threads and will need different treatment. Additionally the modules that `wasm32-wasip3` needs all already work on all other WASI targets as well -- for example the `pthread_*` symbols needed to manage destructors are exposed by `wasi-libc`.\n\nThe end result is that the `wasm32-wasip3` target will be \"ready for threads\" as soon as `wasi-libc` has support. Other targets shouldn\u0027t have any functional difference from before, too.\n"

The lldb command runs `lldb_batchmode.main()`\r\n4. the input commands are executed line by line.\r\n5. If the command is a `repr` pseudo-command, it is intercepted and passed to the checking logic\r\n5a. if blessing, `INPUT_DATA` is blank. Each check inserts the appropriate var into `INPUT_DATA`, and then runs the checking logic against `INPUT_DATA` as normal (for sanity reasons)\r\n5b. the checking logic checks the variable against `INPUT_DATA` (\u003c-- this is incomplete atm, see below for what still isn\u0027t finished) and prints any mismatches that occur.\r\n6. Once all commands have been run (or if a `quit`/`exit` command is encountered) `lldb_batchmode` checks 1. have we seen every type that exists in the input data? 2. have we seen every variable that exists in the input data? If not, it reports what was missing and exits with an error code. \r\n6a. If `--bless`, and no errors occurred, and at least 1 `repr` pseudo-command was processed, `INPUT_DATA` is serialized and written to the input data file.\r\n\r\nTo preemptively answer the question \"When blessing, why not just build a second `TargetData` instance and compare `INPUT_DATA` to that?\" - the goal of diffing in python (rather than rust) is to still have access to the underlying LLDB objects for error reporting purposes. \r\n\r\n\u003cdetails\u003e\r\n\u003csummary\u003eSample Output (`basic-types.rs`)\u003c/summary\u003e\r\nThe input data was manually tampered with to force errors (`char32_t` size set to 1, double type renamed to `half`, `int` type deleted)\r\n\r\n```txt\r\nerror: Error while running LLDB\r\nstatus: exit status: 1\r\n... # skipping to repr output for brevity\r\nrepr b\r\nb: Ok\r\nrepr i\r\ni: Ok\r\nrepr c\r\n  [repr error: type \u0027char32_t\u0027] size does not match.\r\n    Expected: \u00271\u0027\r\n    Got: \u00274\u0027\r\nrepr i8\r\ni8: Ok\r\nrepr i16\r\ni16: Ok\r\nrepr i32\r\ni32: Ok\r\nrepr i64\r\ni64: Ok\r\nrepr u\r\nu: Ok\r\nrepr u8\r\nu8: Ok\r\nrepr u16\r\nu16: Ok\r\nrepr u32\r\n  [repr error: type \u0027unsigned int\u0027] type not found in input data\r\nrepr u64\r\nu64: Ok\r\nrepr f32\r\nf32: Ok\r\nrepr f64\r\n  [repr error: type \u0027double\u0027] type not found in input data\r\n[repr error] The following types were expected, but were not tested:\r\n  {\u0027half\u0027}\r\n```\r\n\u003c/details\u003e\r\n\r\n\u003cdetails\u003e\r\n\u003csummary\u003eSample Output (`simple-struct.rs`)\u003c/summary\u003e\r\nThe input data was manually tampered with to force errors.\r\n\r\n* `simple_struct::NoPadding64` field name `y` to `q`\r\n* `simple_struct::NoPadding163264` last field moved to first position\r\n* `simple_struct::InternalPadding` `y` field deleted\r\n* `simple_struct::PaddingAtEnd` `q` field added\r\n\r\nKeep in mind that I edited the *expected* data, not the actual structs in the test file, so the output reports the opposite of the changes i made (sortof) i.e. it reports that `q` was deleted because it exists in the expected data but not in the LLDB object.\r\n\r\n```txt\r\nrepr no_padding16\r\nno_padding16: Ok\r\nrepr no_padding32\r\nno_padding32: Ok\r\nrepr no_padding64\r\n  [repr error: type \u0027simple_struct::NoPadding64\u0027] The following field(s) appear to have been renamed.

We can pretty trivially change how they\u0027re formatted by modifying/replacing these functions.\r\n\r\nAlso, each type in a test is only tested once per test, regardless of how many variables/fields reference it. When a type is seen a second time, if the prior check was a mismatch, it reports that the type does not match and  **does not** repeat the specific error messages of the mismatch. Instead, it directs people to look at the original type error further up in the output. \r\n\r\n# TODO\r\n\r\n- [x] Variable child mismatches don\u0027t have error reporting\r\n- [x] Rearrange the checks a bit so the type check happens midway through the variable check. Some of the variable\u0027s information is useful for the type\u0027s error reporting and vice versa.\r\n- [x] use some info from `lldb_providers` and the original `SBValue` and `SBType` to improve error messages \r\n- [ ] Some sort of warning if the python/lldb version and/or feature flags don\u0027t match\r\n- [x] A few more tests with input data to help verify behavior (one with generics, one with a synthetic/summary provider, probably need to enforce a formatter for `u8`/`i8` at some point to test that too).\r\n- [x] Various improvements to the error message wording/information/formatting/consistency.\r\n- [ ] Probably some other stuff i\u0027m forgetting about that I\u0027ll add in later\r\n\r\nr? @jieyouxu, @Kobzol"

This does fix the underlying issues there.\n\nThis change does affect `binius_field`, the remaining issues are tracked in https://github.com/rust-lang/trait-system-refactor-initiative/issues/274.\n\nThe core idea is that for\n- A\n  - B\n    - A (cycle with initial result)\n- B \u003c---\n\nWe normally run A until we reach a fixpoint. We don\u0027t do so in case trying to do so encounters overflow or the result of `A` ends up ambiguous to avoid performance issues.\n\nWe want to generally keep the provisional cache entries which depend on A around. Evaluating these goals depends on the current provisional result of A. This means it is fine to keep them around if A reached a fixpoint. If we bail without reaching a fixpoint, the provisional result used while computing B differs from the final result of A. This means the entry for B is not valid and we\u0027d need to discard it.\n\nDiscarding all nested provisional cache entries when not reaching a fixpoint causes perf issues. In case the final result of A is ambiguous, then this PR keeps nested cache entries which are ambiguous and don\u0027t have any inference constraints around. That is sound, as having more goals be ambiguous is never an issue, the trait solver can always say \":shrug: idk\". It also shouldn\u0027t cause any incorrect ambiguity errors issues, as changing the provisional result of A to be ambiguity should not change B to go from being ambiguous to something else.\n\nThe current implementation mutated the result of all nested provisional cache entries to be ambiguous, which resulted in incorrect ambiguity errors in https://github.com/rust-lang/trait-system-refactor-initiative/issues/257. This PR differs from that by dropping goals whose result isn\u0027t already ambiguous. That\u0027s means we don\u0027t keep quite as many cache entries around, which is potentially worse for perf, but from what I can tell this doens\u0027t cause issues in practice.\n\nr? BoxyUwU\n"

While exactly one definition survives expansion in any given build, the method itself is actually present in every configuration.\n\nCurrently, rustdoc\u0027s `auto_cfg` only looks at whichever `cfg` survived expansion and tags the method accordingly, generating a misleading \"Available on panic\u003dunwind only\" portability badge in the docs.\n\nThis is the same `auto_cfg` limitation previously addressed in rust-lang/rust#153964, rust-lang/rust#154311, and rust-lang/rust#156426: when an item is split into mutually-exclusive `cfg` variants that collectively cover all builds, rustdoc incorrectly marks it as conditionally available. Issue rust-lang/rust#149786 pointed out `PoisonError::new` as another case of this pattern, but it hadn\u0027t been touched yet.\n\nThis PR applies the same fix as rust-lang/rust#156426 (adding `#[doc(auto_cfg \u003d false)]` to both variants) and adds a regression test to cover this pattern going forward.\n\nr? @GuillaumeGomez\n"

Forward specialization covers `u8 u16\n  u32 u64 usize` (pointer-width-gated for u32/u64); backward specialization is\n  limited to `u8 u16 usize` since `RangeIter\u003cu32\u003e` / `RangeIter\u003cu64\u003e` do not\n  implement `ExactSizeIterator`.\n- `library/coretests/tests/iter/adapters/step_by.rs`: add\n  `test_step_by_new_range_iter` covering forward, backward, and interleaved\n  iteration via the new-range iterator.\n\n## Motivation\n\nFixes rust-lang/rust#157754. The inner loop for `core::range::Range::from(0..n).into_iter().step_by(2)` currently generates noticeably worse assembly than the equivalent `(0..n).step_by(2)` because specialization did not cover `RangeIter`.\n\nr? libs\n"

For unnamed consts, it will create additional internal \u0026 hidden symbols so that they can be referenced by global_asm.\n\n~~The feature is also implemented for GCC backend but it\u0027s untested.~~ Tested now.\n"

(That\u0027s unfortunate, but fixing it is outside the scope of this PR.)\n\nCurrently those code paths are skipped using `#[cfg(test)]` and `#[cfg(not(test))]`, which does achieve the desired effect, but has a few downsides. The stubbed-out code triggers dead-code and unused-import warnings, and makes IDE navigation harder when rust-analyzer treats `cfg(test)` as true when analyzing the code.\n\nIf we switch to using `cfg!(test)` and `cfg!(not(test))` to “dynamically” skip the relevant code paths, it still gets skipped, but the skipped code is still considered live for the purpose of dead-code warnings and IDE analysis.\n"
