2025-08-08Rollup merge of #144192 - RalfJung:atomicrmw-ptr, r=nikicTrevor Gross-1/+6
atomicrmw on pointers: move integer-pointer cast hacks into backend Conceptually, we want to have atomic operations on pointers of the form `fn atomic_add(ptr: *mut T, offset: usize, ...)`. However, LLVM does not directly support such operations (https://github.com/llvm/llvm-project/issues/120837), so we have to cast the `offset` to a pointer somewhere. This PR moves that hack into the LLVM backend, so that the standard library, intrinsic, and Miri all work with the conceptual operation we actually want. Hopefully, one day LLVM will gain a way to represent these operations without integer-pointer casts, and then the hack will disappear entirely. Cc ```@nikic``` -- this is the best we can do right now, right? Fixes https://github.com/rust-lang/rust/issues/134617

Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the prelude instead of importing or qualifying them. These functions were added to all preludes in Rust 1.80.

things which are already immediates That means it stops trying to truncate things that are already `i1`s.
2025-02-19Emit `trunc nuw` for unchecked shifts and `to_immediate_scalar`Scott McMurray-1/+1
- For shifts this shrinks the IR by no longer needing an `assume` while still providing the UB information - Having this on the `i8`→`i1` truncations will hopefully help with some places that have to load `i8`s or pass those in LLVM structs without range information
2025-02-13Set both `nuw` and `nsw` in slice size calculationScott McMurray-25/+1
There's an old note in the code to do this, and now that LLVM-C has an API for it, we might as well.

the behavior of the type system not only depends on the current assumptions, but also the currentnphase of the compiler. This is mostly necessary as we need to decide whether and how to reveal opaque types. We track this via the `TypingMode`.

llvm: replace some deprecated functions `LLVMMDStringInContext` and `LLVMMDNodeInContext` are deprecated, replace them with `LLVMMDStringInContext2` and `LLVMMDNodeInContext2`. Also replace `Value` with `Metadata` in some function signatures for better consistency.

2024-09-17Rename supertraits of `CodegenMethods`.Nicholas Nethercote-2/+2
Supertraits of `BuilderMethods` are all called `XyzBuilderMethods`. Supertraits of `CodegenMethods` are all called `XyzMethods`. This commit changes the latter to `XyzCodegenMethods`, for consistency.
2024-09-17Merge `HasCodegen` into `BuilderMethods`.Nicholas Nethercote-6/+4
It has `Backend` and `Deref` boudns, plus an associated type `CodegenCx`, and it has a single use. This commit "inlines" it into `BuilderMethods`, which makes the complicated backend trait situation a little simpler.
