Remove outdated rustc_allocator test

2022-07-27T14:19:07+00:00

This attribute now does more than just place noalias on the return, and has specific requirements for the signature. Drop the test entirely, as we already check __rust_alloc attributes in other codegen tests.

do not mark interior mutable shared refs as dereferenceable

2022-07-22T18:25:41+00:00

Update some codegen tests for opaque pointers

2022-05-25T15:29:37+00:00

Apply noundef attribute to all scalar types which do not permit raw init

2022-02-26T21:42:33+00:00

Beyond `&`/`&mut`/`Box`, this covers `char`, discriminants, `NonZero*`, etc. All such types currently cause a Miri error if left uninitialized, and an `invalid_value` lint in cases like `mem::uninitialized::()` Note that this _does not_ change whether or not it is UB for `u64` (or other integer types with no invalid values) to be undef.

apply noundef explicitly in all cases instead of relying on dereferenceable implying it

2022-02-07T02:11:11+00:00

test that MaybeUninit is not noundef

2022-02-07T02:09:21+00:00

Apply noundef attribute to &T, &mut T, Box, bool

2022-02-05T06:09:52+00:00

This doesn't handle `char` because it's a bit awkward to distinguish it from u32 at this point in codegen. Note that for some types (like `&Struct` and `&mut Struct`), we already apply `dereferenceable`, which implies `noundef`, so the IR does not change.

Update the minimum external LLVM to 12

2021-10-22T17:50:07+00:00

Remove redundant `ignore-tidy-linelength` annotations

2021-04-03T20:30:20+00:00

This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed.

Don't compute optimized PointerKind for unoptimized builds

2021-03-21T19:54:42+00:00

This saves us both the Freeze/Unpin queries, and avoids placing noalias attributes, which have a compile-time impact on LLVM even in optnone builds (due to always_inline functions).
