2022-08-19Rollup merge of #100208 - RalfJung:dyn-upcast-nop, r=petrochenkovDylan DPC-0/+1
make NOP dyn casts not require anything about the vtable As suggested [on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/144729-t-types/topic/dyn-upcasting.20stabilization/near/292151439). This matches what the codegen backends already do, and what Miri did do until https://github.com/rust-lang/rust/pull/99420 when I made it super extra paranoid.

This avoids monomorphizing all linker code for each codegen backend and will allow passing in extra information to the archive builder from the codegen backend.

2022-07-26Auto merge of #98989 - dpaoliello:rawdylibbin, r=michaelwoeristerbors-5/+9
Enable raw-dylib for bin crates Fixes #93842 When `raw-dylib` is used in a `bin` crate, we need to collect all of the `raw-dylib` functions, generate the import library and add that to the linker command line. I also changed the tests so that 1) the C++ dlls are created after the Rust dlls, thus there is no chance of accidentally using them in the Rust linking process and 2) disabled generating import libraries when building with MSVC.

2022-07-17Auto merge of #99033 - 5225225:interpreter-validity-checks, r=oli-obkbors-13/+2
Use constant eval to do strict mem::uninit/zeroed validity checks I'm not sure about the code organisation here, I just dumped the check in rustc_const_eval at the root. Not hard to move it elsewhere, in any case. Also, this means cranelift codegen intrinsics lose the strict checks, since they don't seem to depend on rustc_const_eval, and I didn't see a point in keeping around two copies. I also left comments in the is_zero_valid methods about "uhhh help how do i do this", those apply to both methods equally. Also rustc_codegen_ssa now depends on rustc_const_eval... is this okay? Pinging `@RalfJung` since you were the one who mentioned this to me, so I'm assuming you're interested. Haven't had a chance to run full tests on this since it's really warm, and it's 1AM, I'll check out any failures/comments in the morning :)

Change enum->int casts to not go through MIR casts. follow-up to https://github.com/rust-lang/rust/pull/96814 this simplifies all backends and even gives LLVM more information about the return value of `Rvalue::Discriminant`, enabling optimizations in more cases.

Remove the source archive functionality of ArchiveWriter We now build archives through strictly additive means rather than taking an existing archive and potentially substracting parts. This is simpler and makes it easier to swap out the archive writer in https://github.com/rust-lang/rust/pull/97485.

Make `std::mem::needs_drop` accept `?Sized` This change attempts to make `needs_drop` work with types like `[u8]` and `str`. This enables code in types like `Arc<T>` that was not possible before, such as https://github.com/rust-lang/rust/pull/97676.

2022-06-14Rename the `ConstS::val` field as `kind`.Nicholas Nethercote-4/+4
And likewise for the `Const::val` method. Because its type is called `ConstKind`. Also `val` is a confusing name because `ConstKind` is an enum with seven variants, one of which is called `Value`. Also, this gives consistency with `TyS` and `PredicateS` which have `kind` fields. The commit also renames a few `Const` variables from `val` to `c`, to avoid confusion with the `ConstKind::Value` variant.
