2023-02-15Rollup merge of #107163 - mikebenfield:parameters-pr, r=TaKO8KiDylan DPC-46/+2
Remove some superfluous type parameters from layout.rs. Specifically remove V, which can always be VariantIdx, and F, which can always be Layout.
2023-01-22abi: add `AddressSpace` field to `Primitive::Pointer`Erik Desjardins-5/+5
...and remove it from `PointeeInfo`, which isn't meant for this. There are still various places (marked with FIXMEs) that assume all pointers have the same size and alignment. Fixing this requires parsing non-default address spaces in the data layout string, which will be done in a followup.
2023-01-22rustc_abi: remove Primitive::{is_float,is_int}Erik Desjardins-3/+3
there were fixmes for this already i am about to remove is_ptr (since callers need to properly distinguish between pointers in different address spaces), so might as well do this at the same time

2022-12-18A few small cleanups for `newtype_index`Nilstrieb-2/+1
Remove the `..` from the body, only a few invocations used it and it's inconsistent with rust syntax. Use `;` instead of `,` between consts. As the Rust syntax gods inteded.

2022-11-19Rollup merge of #104001 - Ayush1325:custom-entry, r=bjorn3Dylan DPC-0/+28
Improve generating Custom entry function This commit is aimed at making compiler-generated entry functions (Basically just C `main` right now) more generic so other targets can do similar things for custom entry. This was initially implemented as part of https://github.com/rust-lang/rust/pull/100316. Currently, this moves the entry function name and Call convention to the target spec.

2022-09-07Change name of "dataful" variant to "untagged"Michael Benfield-2/+2
This is in anticipation of a new enum layout, in which the niche optimization may be applied even when multiple variants have data.
2022-08-26Move `ArgAbi::pad_i32` into `PassMode::Cast`.Nicholas Nethercote-22/+15
Because it's only needed for that variant. This shrinks the types and clarifies the logic.
2022-08-26Turn `ArgAbi::pad` into a `bool`.Nicholas Nethercote-8/+8
Because it's only ever set to `None` or `Some(Reg::i32())`.
2022-08-26Change `FnAbi::args` to a boxed slice.Nicholas Nethercote-25/+25
2022-08-26Change `FnAbi::fixed_count` to a `u32`.Nicholas Nethercote-3/+3
2022-08-26Box `CastTarget` within `PassMode`.Nicholas Nethercote-5/+5
Because `PassMode::Cast` is by far the largest variant, but is relatively rare. This requires making `PassMode` not impl `Copy`, and `Clone` is no longer necessary. This causes lots of sigil adjusting, but nothing very notable.

2022-08-02Auto merge of #92268 - jswrenn:transmute, r=oli-obkbors-1/+2
Initial implementation of transmutability trait. *T'was the night before Christmas and all through the codebase, not a miri was stirring — no hint of `unsafe`!* This PR provides an initial, **incomplete** implementation of *[MCP 411: Lang Item for Transmutability](https://github.com/rust-lang/compiler-team/issues/411)*. The `core::mem::BikeshedIntrinsicFrom` trait provided by this PR is implemented on-the-fly by the compiler for types `Src` and `Dst` when the bits of all possible values of type `Src` are safely reinterpretable as a value of type `Dst`. What this PR provides is: - [x] [support for transmutations involving primitives](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/primitives) - [x] [support for transmutations involving arrays](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/arrays) - [x] [support for transmutations involving structs](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/structs) - [x] [support for transmutations involving enums](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/enums) - [x] [support for transmutations involving unions](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/unions) - [x] [support for weaker validity checks](https://github.com/jswrenn/rust/blob/transmute/src/test/ui/transmutability/unions/should_permit_intersecting_if_validity_is_assumed.rs) (i.e., `Assume::VALIDITY`) - [x] visibility checking What isn't yet implemented: - [ ] transmutability options passed using the `Assume` struct - [ ] [support for references](https://github.com/jswrenn/rust/blob/transmute/src/test/ui/transmutability/references.rs) - [ ] smarter error messages These features will be implemented in future PRs.
2022-08-01Auto merge of #99476 - dpaoliello:rawdylibvectorcall, r=michaelwoeristerbors-5/+7
Add tests for raw-dylib with vectorcall, and fix vectorcall code generation * Adds tests for using `raw-dylib` (#58713) with `vectorcall`. * Fixed code generation for `vectorcall` (parameters have to be marked with `InReg`, just like `fastcall`). * Enabled running the `raw-dylib` `fastcall` tests when using MSVC (since I had to add support in the test for running MSVC-only tests since GCC doesn't support `vectorcall`).
