cfg(version): treat nightlies as complete This PR makes cfg(version) treat the nightlies for version 1.n.0 as 1.n.0, even though that nightly version might not have all stabilizations and features of the released 1.n.0. This is done for greater convenience for people who want to test a newly stabilized feature on nightly, or in other words, give newly stabilized features as many eyeballs as possible. For users who wish to pin nightlies, this commit adds a -Z assume-incomplete-release option that they can enable if they run into any issues due to this change. Implements the suggestion in https://github.com/rust-lang/rust/issues/64796#issuecomment-640851454

2021-01-26Auto merge of #80692 - Aaron1011:feature/query-result-debug, r=estebankbors-3/+3
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.
2021-01-24Replace version_check dependency with own version parsing codeest31-4/+28
This gives compiler maintainers a better degree of control over how the version gets parsed and is a good way to ensure that there are no changes of behaviour in the future. Also, issue a warning if the version is invalid instead of erroring so that we stay forwards compatible with possible future changes of the versioning scheme. Last, this improves the present test a little.

2020-12-14Get rid of `clean::Deprecation`Joshua Nelson-1/+1
This brings the size of `item.deprecation` from 56 to 16 bytes.

2020-11-20Never inline naked functionsTomasz Miąsko-1/+1
The `#[naked]` attribute disabled prologue / epilogue emission for the function and it is responsibility of a developer to provide them. The compiler is no position to inline such functions correctly. Disable inlining of naked functions at LLVM and MIR level.

2020-10-11Move `PartialOrd` impl out of rustcJoshua Nelson-14/+0
Rustdoc's ordering requirements are probably not relevant to the rest of the compiler.
2020-10-11Switch rustdoc from `clean::Stability` to `rustc_attr::Stability`Joshua Nelson-1/+15
This gives greater type safety and is less work to maintain on the rustdoc end.

2020-09-27Remove `rustc_allow_const_fn_ptr`Dylan MacKenzie-24/+7
This was a hack to work around the lack of an escape hatch for the "min `const fn`" checks in const-stable functions. Now that we have co-opted `allow_internal_unstable` for this purpose, we no longer need the bespoke attribute.
