2021-03-09rustc_target: add "unwind" payloads to `Abi`katelyn a. martin-1/+1
### Overview This commit begins the implementation work for RFC 2945. For more information, see the rendered RFC [1] and tracking issue [2]. A boolean `unwind` payload is added to the `C`, `System`, `Stdcall`, and `Thiscall` variants, marking whether unwinding across FFI boundaries is acceptable. The cases where each of these variants' `unwind` member is true correspond with the `C-unwind`, `system-unwind`, `stdcall-unwind`, and `thiscall-unwind` ABI strings introduced in RFC 2945 [3]. ### Feature Gate and Unstable Book This commit adds a `c_unwind` feature gate for the new ABI strings. Tests for this feature gate are included in `src/test/ui/c-unwind/`, which ensure that this feature gate works correctly for each of the new ABIs. A new language features entry in the unstable book is added as well. ### Further Work To Be Done This commit does not proceed to implement the new unwinding ABIs, and is intentionally scoped specifically to *defining* the ABIs and their feature flag. ### One Note on Test Churn This will lead to some test churn, in re-blessing hash tests, as the deleted comment in `src/librustc_target/spec/abi.rs` mentioned, because we can no longer guarantee the ordering of the `Abi` variants. While this is a downside, this decision was made bearing in mind that RFC 2945 states the following, in the "Other `unwind` Strings" section [3]: > More unwind variants of existing ABI strings may be introduced, > with the same semantics, without an additional RFC. Adding a new variant for each of these cases, rather than specifying a payload for a given ABI, would quickly become untenable, and make working with the `Abi` enum prone to mistakes. This approach encodes the unwinding information *into* a given ABI, to account for the future possibility of other `-unwind` ABI strings. ### Ignore Directives `ignore-*` directives are used in two of our `*-unwind` ABI test cases. Specifically, the `stdcall-unwind` and `thiscall-unwind` test cases ignore architectures that do not support `stdcall` and `thiscall`, respectively. These directives are cribbed from `src/test/ui/c-variadic/variadic-ffi-1.rs` for `stdcall`, and `src/test/ui/extern/extern-thiscall.rs` for `thiscall`. This would otherwise fail on some targets, see: https://github.com/rust-lang-ci/rust/commit/fcf697f90206e9c87b39d494f94ab35d976bfc60 ### Footnotes [1]: https://github.com/rust-lang/rfcs/blob/master/text/2945-c-unwind-abi.md [2]: https://github.com/rust-lang/rust/issues/74990 [3]: https://github.com/rust-lang/rfcs/blob/master/text/2945-c-unwind-abi.md#other-unwind-abi-strings

2021-01-30Rollup merge of #80959 - jhpratt:unsigned_abs-stabilization, r=m-ou-seYuki Okushi-1/+1
Stabilize `unsigned_abs` Resolves #74913. This PR stabilizes the `i*::unsigned_abs()` method, which returns the absolute value of an integer _as its unsigned equivalent_. This has the advantage that it does not overflow on `i*::MIN`. I have gone ahead and used this in a couple locations throughout the repository.

Move binder for dyn to each list item This essentially changes `ty::Binder<&'tcx List<ExistentialTraitRef>>` to `&'tcx List<ty::Binder<ExistentialTraitRef>>`. This is a first step in moving the `dyn Trait` representation closer to Chalk, which we've talked about in `@rust-lang/wg-traits.` r? `@nikomatsakis`

2020-12-14Improve warnings on incompatible options involving -Zinstrument-coverageRich Kadel-1/+5
Adds checks for: * `no_core` attribute * explicitly-enabled `legacy` symbol mangling * mir_opt_level > 1 (which enables inlining) I removed code from the `Inline` MIR pass that forcibly disabled inlining if `-Zinstrument-coverage` was set. The default `mir_opt_level` does not enable inlining anyway. But if the level is explicitly set and is greater than 1, I issue a warning. The new warnings show up in tests, which is much better for diagnosing potential option conflicts in these cases.

2020-10-15Replace target.target with target and target.ptr_width with target.pointer_widthest31-1/+1
Preparation for a subsequent change that replaces rustc_target::config::Config with its wrapped Target. On its own, this commit breaks the build. I don't like making build-breaking commits, but in this instance I believe that it makes review easier, as the "real" changes of this PR can be seen much more easily.
