| simd_select_bitmask: the 'padding' bits in the mask are just ignored Fixes https://github.com/rust-lang/rust/issues/137942: we documented simd_select_bitmask to require the 'padding' bits in the mask (the mask can sometimes be longer than the vector; I am referring to these extra bits as 'padding' here) to be zero, mostly because nobody felt like doing the research for what should be done when they are non-zero. However, codegen is already perfectly happy just ignoring them, so in practice they can have any value. Some of the intrinsic wrappers in stdarch have trouble ensuring that they are zero. So let's just adjust the docs and Miri to permit non-zero 'padding' bits. Cc ````@Amanieu```` ````@workingjubilee```` | ||||

| simd intrinsics with mask: accept unsigned integer masks, and fix some of the errors It's not clear at all why the mask would have to be signed, it is anyway interpreted bitwise. The backend should just make sure that works no matter the surface-level type; our LLVM backend already does this correctly. The note of "the mask may be widened, which only has the correct behavior for signed integers" explains... nothing? Why can't the code do the widening correctly? If necessary, just cast to the signed type first... Also while we are at it, fix the errors. For simd_masked_load/store, the errors talked about the "third argument" but they meant the first argument (the mask is the first argument there). They also used the wrong type for `expected_element`. I have extremely low confidence in the GCC part of this PR.

| Fix inaccurate `std::intrinsics::simd` documentation This addresses two issues: - the docs on comparison operators (`simd_gt` etc.) said they only work for floating-point vectors, but they work for integer vectors too. - the docs on various functions that use a mask did not document that the mask must be a signed integer vector. Unsigned integer vectors would cause invalid behavior when the mask vector is widened (unsigned integers would use zero extension, producing incorrect results). r? ``@workingjubilee`` | ||||

| 2024-04-02 | Rollup merge of #122935 - RalfJung:with-exposed-provenance, r=Amanieu | Jacob Pratt | -0/+7 | |
| rename ptr::from_exposed_addr -> ptr::with_exposed_provenance As discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/To.20expose.20or.20not.20to.20expose/near/427757066). The old name, `from_exposed_addr`, makes little sense as it's not the address that is exposed, it's the provenance. (`ptr.expose_addr()` stays unchanged as we haven't found a better option yet. The intended interpretation is "expose the provenance and return the address".) The new name nicely matches `ptr::without_provenance`. | ||||
