2025-02-04cg_gcc: Directly use rustc_abi instead of reexportsJubilee Young-8/+8
2025-01-15Use a C-safe return type for `__rust_[ui]128_*` overflowing intrinsicsTrevor Gross-2/+4
Combined with [1], this will change the overflowing multiplication operations to return an `extern "C"`-safe type. Link: https://github.com/rust-lang/compiler-builtins/pull/735 [1]

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`.

2024-10-11intrinsics.fmuladdf{16,32,64,128}: expose llvm.fmuladd.* semanticsJed Brown-0/+3
Add intrinsics `fmuladd{f16,f32,f64,f128}`. This computes `(a * b) + c`, to be fused if the code generator determines that (i) the target instruction set has support for a fused operation, and (ii) that the fused operation is more efficient than the equivalent, separate pair of `mul` and `add` instructions. https://llvm.org/docs/LangRef.html#llvm-fmuladd-intrinsic MIRI support is included for f32 and f64. The codegen_cranelift uses the `fma` function from libc, which is a correct implementation, but without the desired performance semantic. I think this requires an update to cranelift to expose a suitable instruction in its IR. I have not tested with codegen_gcc, but it should behave the same way (using `fma` from libc).

2024-09-17Rename supertraits of `CodegenMethods`.Nicholas Nethercote-3/+3
Supertraits of `BuilderMethods` are all called `XyzBuilderMethods`. Supertraits of `CodegenMethods` are all called `XyzMethods`. This commit changes the latter to `XyzCodegenMethods`, for consistency.
2024-09-17Rename `{ArgAbi,IntrinsicCall}Methods`.Nicholas Nethercote-3/+3
They both are part of `BuilderMethods`, and so should have `Builder` in their name like all the other traits in `BuilderMethods`.

2024-04-24Auto merge of #122053 - erikdesjardins:alloca, r=nikicbors-3/+3
Stop using LLVM struct types for alloca The alloca type has no semantic meaning, only the size (and alignment, but we specify it explicitly) matter. Using `[N x i8]` is a more direct way to specify that we want `N` bytes, and avoids relying on LLVM's struct layout. It is likely that a future LLVM version will change to an untyped alloca representation. Split out from #121577. r? `@ghost`

2024-03-23CFI: Use Instance at callsitesMatthew Maurer-5/+6
We already use `Instance` at declaration sites when available to glean additional information about possible abstractions of the type in use. This does the same when possible at callsites as well. The primary purpose of this change is to allow CFI to alter how it generates type information for indirect calls through `Virtual` instances.
