* Merge #8813bors[bot]2021-05-161-20/+12
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8813: Get some more array lengths! r=lf- a=lf- This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of: * `let a: [u8; 2] = ...` * `let a = b"aaa"` * `let a = [0u8; 4]` I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!). Fixes #2922.

| * Address final feedbackJade2021-05-161-3/+2
| | | | | | | | | | * rename ConstExtension->ConstExt * refactor a manual construction of a Const
| * Add more tests, refactor array lengths/consteval workJade2021-05-141-33/+8
| | | | | | | | | | | | | | | | | | | | | | Fix #2922: add unknown length as a condition for a type having unknown. Incorporate reviews: * Extract some of the const evaluation workings into functions * Add fixmes on the hacks * Add tests for impls on specific array lengths (these work!!! 😁) * Add tests for const generics (indeed we don't support it yet)
| * Add support for lengths in array repeats, if they are literalsJade2021-05-131-6/+16
| | | | | | | | Now we will get the type of `[0u8; 4]`.
| * Support length for ByteStringsJade2021-05-131-6/+14
| | | | | | | | I am not confident that my added byte string parsing is right.
| * Add lowering of array lengths in typesJade2021-05-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | Now e.g. ```rust fn a(b: [u8; 2]) { } ``` will know about the length of b.

* Merge #8799bors[bot]2021-05-121-6/+20
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 8799: Add basic support for array lengths in types r=flodiebold a=lf- This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range array declarations are unsupported as before. I don't know why a bunch of our rustc tests had single quotes inside strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's bad? Maybe something in a nightly?

| | | | | | Now that we're using Chalk's `substitute` which actually knows about lifetimes, the hack doesn't work anymore, but we can put in a proper lifetime.

|/ | | | | | I'd prefer getting rid of it, but it's used in the impl search and not super easy to replace there (I think ideally the impl search would do proper unification, but that's a bit more complicated).
* Remove Ty::substs{_mut}Florian Diebold2021-04-072-3/+8
| | | | | | Almost all uses actually only care about ADT substs, so it's better to be explicit. The methods were a bad abstraction anyway since they already didn't include the inner types of e.g. `TyKind::Ref` anymore.

|\ | | | | | | | | | | | | | | | | | | 8364: Memory usage improvements r=jonas-schievink a=alexmaco These are mostly focused on splitting up enum variants with large size differences between variants by `Box`-ing things up. In my testing this reduces the memory usage somewhere in the low percentages, even though the measurements are quite noisy. Co-authored-by: Alexandru Macovei <[email protected]>
| * Use Box'es to reduce the size of hir_def::expr::Pat from 112 to 64 bytes on ↵Alexandru Macovei2021-04-061-2/+2
| | | | | | | | 64bit
| * Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on ↵Alexandru Macovei2021-04-061-2/+8
| | | | | | | | | | | | | | | | | | | | 64bit systems) Rationale: only a minority of variants used almost half the size. By keeping large members (especially in Option) behind a box the memory cost is only payed when the large variants are needed. This reduces the size Vec<Expr> needs to allocate.

* Fix shifting of binders in FnPointerFlorian Diebold2021-04-051-2/+4
| | | | | | | | | - don't shift in/out for Chalk mapping (we want to have the same binders now) - do shift in when creating the signature for a closure (though it shouldn't matter much) - do shift in when lowering a `fn()` type - correctly deal with the implied binder in TypeWalk
