* Merge #8813bors[bot]2021-05-1611-103/+251
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 feedbackJade2021-05-163-31/+17
| | | | | | | | | | * rename ConstExtension->ConstExt * refactor a manual construction of a Const
| * Add more tests, refactor array lengths/consteval workJade2021-05-145-34/+179
| | | | | | | | | | | | | | | | | | | | | | 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)
| * Test lowering byte strings some moreJade2021-05-131-14/+25
| |
| * Add support for lengths in array repeats, if they are literalsJade2021-05-132-7/+17
| | | | | | | | Now we will get the type of `[0u8; 4]`.
| * Support length for ByteStringsJade2021-05-132-8/+16
| | | | | | | | I am not confident that my added byte string parsing is right.
| * Add lowering of array lengths in typesJade2021-05-139-76/+64
| | | | | | | | | | | | | | | | | | | | | | Now e.g. ```rust fn a(b: [u8; 2]) { } ``` will know about the length of b.

* Merge #8799bors[bot]2021-05-1211-109/+155
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 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?

| | | | | | | This isn't actually how it works, you have to specify the exact trait that has the associated type. Fixes #8686.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8432: decl_check: consider outer scopes' allows r=jonas-schievink a=lf- Fix #8417. Also makes it less noisy about no_mangle annotated stuff the user can do nothing about. Note: this still is broken with bitfield! macros. A repro in an ignore test is included here. I believe this bug is elsewhere, and I don't think I can work around it here. I would like help filing the remaining bug, as it does actually affect users, but I don't know how to describe the behaviour (or even if it is unintended). Co-authored-by: Jade <[email protected]>
