2023-07-07Rename `adjustment::PointerCast` and variants using it to `PointerCoercion`Nilstrieb-7/+11
It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related casts, when in reality their just used to share a some enum variants. Make it clear there these are only coercion to make it clear why only some pointer related "casts" are in the enum.

2023-05-03Restrict `From<S>` for `{D,Subd}iagnosticMessage`.Nicholas Nethercote-2/+2
Currently a `{D,Subd}iagnosticMessage` can be created from any type that impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static, str>`, which are reasonable. It also includes `&String`, which is pretty weird, and results in many places making unnecessary allocations for patterns like this: ``` self.fatal(&format!(...)) ``` This creates a string with `format!`, takes a reference, passes the reference to `fatal`, which does an `into()`, which clones the reference, doing a second allocation. Two allocations for a single string, bleh. This commit changes the `From` impls so that you can only create a `{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static, str>`. This requires changing all the places that currently create one from a `&String`. Most of these are of the `&format!(...)` form described above; each one removes an unnecessary static `&`, plus an allocation when executed. There are also a few places where the existing use of `&String` was more reasonable; these now just use `clone()` at the call site. As well as making the code nicer and more efficient, this is a step towards possibly using `Cow<'static, str>` in `{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing the `From<&'a str>` impls to `From<&'static str>`, which is doable, but I'm not yet sure if it's worthwhile.

2023-04-06Rename `Abort` terminator to `Terminate`Gary Guo-1/+1
Unify terminology used in unwind action and terminator, and reflect the fact that a nounwind panic is triggered instead of an immediate abort is triggered for this terminator.

2023-04-01Use `FieldIdx` in various things related to aggregatesScott McMurray-3/+4
Shrank `AggregateKind` by 8 bytes on x64, since the active field of a union is tracked as an `Option<FieldIdx>` instead of `Option<usize>`.
2023-03-31Auto merge of #98112 - saethlin:mir-alignment-checks, r=oli-obkbors-0/+12
Insert alignment checks for pointer dereferences when debug assertions are enabled Closes https://github.com/rust-lang/rust/issues/54915 - [x] Jake tells me this sounds like a place to use `MirPatch`, but I can't figure out how to insert a new basic block with a new terminator in the middle of an existing basic block, using `MirPatch`. (if nobody else backs up this point I'm checking this as "not actually a good idea" because the code looks pretty clean to me after rearranging it a bit) - [x] Using `CastKind::PointerExposeAddress` is definitely wrong, we don't want to expose. Calling a function to get the pointer address seems quite excessive. ~I'll see if I can add a new `CastKind`.~ `CastKind::Transmute` to the rescue! - [x] Implement a more helpful panic message like slice bounds checking. r? `@oli-obk`
2023-03-28Move `mir::Field` → `abi::FieldIdx`Scott McMurray-1/+1
The first PR for https://github.com/rust-lang/compiler-team/issues/606 This is just the move-and-rename, because it's plenty big-and-bitrotty already. Future PRs will start using `FieldIdx` more broadly, and concomitantly removing `FieldIdx::new`s.
2023-03-25Refactor: `VariantIdx::from_u32(0)` -> `FIRST_VARIANT`Scott McMurray-1/+1
Since structs are always `VariantIdx(0)`, there's a bunch of files where the only reason they had `VariantIdx` or `vec::Idx` imported at all was to get the first variant. So this uses a constant for that, and adds some doc-comments to `VariantIdx` while I'm there, since it doesn't have any today.

2023-03-22Add `CastKind::Transmute` to MIRScott McMurray-0/+4
Updates `interpret`, `codegen_ssa`, and `codegen_cranelift` to consume the new cast instead of the intrinsic. Includes `CastTransmute` for custom MIR building, to be able to test the extra UB.
