2021-04-08Fix outdated crate names in compiler docspierwill-1/+1
Changes `librustc_X` to `rustc_X`, only in documentation comments. Plain code comments are left unchanged. Also fix incorrect file paths.
2021-03-27Remove (lots of) dead codeJoshua Nelson-10/+0
Found with https://github.com/est31/warnalyzer. Dubious changes: - Is anyone else using rustc_apfloat? I feel weird completely deleting x87 support. - Maybe some of the dead code in rustc_data_structures, in case someone wants to use it in the future? - Don't change rustc_serialize I plan to scrap most of the json module in the near future (see https://github.com/rust-lang/compiler-team/issues/418) and fixing the tests needed more work than I expected. TODO: check if any of the comments on the deleted code should be kept.

Any use of it has been shown to be a bug in the past.

2021-03-12Implement valtreeOli Scherer-1/+1
valtree is a version of constants that is inherently safe to be used within types. This is in contrast to ty::Const which can have different representations of the same value. These representation differences can show up in hashing or equality comparisons, breaking type equality of otherwise equal types. valtrees do not have this problem.
2021-03-06Change x64 size checks to not apply to x32.Harald van Dijk-5/+5
Rust contains various size checks conditional on target_arch = "x86_64", but these checks were never intended to apply to x86_64-unknown-linux-gnux32. Add target_pointer_width = "64" to the conditions.

Scalars can represent integers up to u128, but the docs state otherwise.
2021-01-30Rollup merge of #80959 - jhpratt:unsigned_abs-stabilization, r=m-ou-seYuki Okushi-11/+2
Stabilize `unsigned_abs` Resolves #74913. This PR stabilizes the `i*::unsigned_abs()` method, which returns the absolute value of an integer _as its unsigned equivalent_. This has the advantage that it does not overflow on `i*::MIN`. I have gone ahead and used this in a couple locations throughout the repository.
2021-01-26Auto merge of #80692 - Aaron1011:feature/query-result-debug, r=estebankbors-1/+1
Enforce that query results implement Debug Currently, we require that query keys implement `Debug`, but we do not do the same for query values. This can make incremental compilation bugs difficult to debug - there isn't a good place to print out the result loaded from disk. This PR adds `Debug` bounds to several query-related functions, allowing us to debug-print the query value when an 'unstable fingerprint' error occurs. This required adding `#[derive(Debug)]` to a fairly large number of types - hopefully, this doesn't have much of an impact on compiler bootstrapping times.

2020-10-06Rollup merge of #76995 - LingMan:middle_matches, r=varkorYuki Okushi-12/+6
Reduce boilerplate with the matches! macro Replaces simple bool `match`es of the form match $expr { $pattern => true _ => false } and their inverse with invocations of the matches! macro. Limited to rustc_middle for now to get my feet wet.

2020-09-20Auto merge of #74949 - oli-obk:validate_const_eval_raw, r=RalfJungbors-17/+17
Validate constants during `const_eval_raw` This PR implements the groundwork for https://github.com/rust-lang/rust/issues/72396 * constants are now validated during `const_eval_raw` * to prevent cycle errors, we do not validate references to statics anymore beyond the fact that they are not dangling * the `const_eval` query ICEs if used on `static` items * as a side effect promoteds are now evaluated to `ConstValue::Scalar` again (since they are just a reference to the actual promoted allocation in most cases).
