2021-08-31Auto merge of #88414 - Aaron1011:guess-foreign-head-span, r=estebankbors-15/+97
Don't use `guess_head_span` in `predicates_of` for foreign span Previously, the result of `predicates_of` for a foreign trait would depend on the *current* state of the corresponding source file in the foreign crate. This could lead to ICEs during incremental compilation, since the on-disk contents of the upstream source file could potentially change without the upstream crate being recompiled. Additionally, this ensure that that the metadata we produce for a crate only depends on its *compiled* upstream dependencies (e.g an rlib or rmeta file), *not* the current on-disk state of the upstream crate source files.
2021-08-30Expand documentation for `FpCategory`.Kevin Reid-4/+22
I intend these changes to be helpful to readers who are not yet familiar with the quirks of floating-point numbers. Additionally, I felt it was misleading to describe `Nan` as being the result of division by zero, since most divisions by zero (except for 0/0) produce `Infinite` floats, so I moved that remark to the `Infinite` variant with adjustment. The first sentence of the `Nan` documentation is copied from `f32`; I followed the example of the `f64` documentation by referring to `f32` for general concepts, rather than duplicating the text.

update const generics feature gates **tl;dr: split const generics into three features: `adt_const_params`, `const_generics_defaults` and `generic_const_exprs`** continuing the work of `@BoxyUwU` in #88324, this PR - renames `feature(const_evaluatable_checked)` to `feature(generic_const_exprs)` which now doesn't need any other feature gate to work. Previously `feature(const_evaluatable_checked)` was only useful in combination with `feature(const_generics)`. - completely removes `feature(lazy_normalization_consts)`. This feature only supplied the parents generics to anonymous constants, which is pretty useless as generic anon consts are only allowed with `feature(generic_const_exprs)` anyways. - moves the ability to use additional const param types from `feature(const_generics)` into `feature(adt_const_params)`. As `feature(const_generics)` is now mostly useless without `feature(generic_const_exprs)` we also remove that feature flag. - updates tests, removing duplicates and unnecessary revisions in some cases and also deletes all unused `*.stderr` files. I not also remove the ordering restriction for const and type parameters if any of the three const generics features is active. This ordering restriction feels like the only "real" use of the current `feature(const_generics)` right now so this change isn't a perfect solution, but as I intend to stabilize the ordering - and `feature(const_generics_defaults)` - in the very near future, I think this is acceptable for now. --- cc `@rust-lang/project-const-generics` about the new feature names and this change in general. I don't think we need any external approval for this change but I do intend to publish an update to the const generics tracking issue the day this PR lands, so I don't want this merged yet. Apologies to whoever ends up reviewing this PR :sweat_smile: :heart: r? rust-lang/project-const-generics
