Move ZST ABI handling to `rustc_target`
Currently, target specific handling of ZST function call ABI (specifically passing them indirectly instead of ignoring them) is handled in `rustc_ty_utils`, whereas all other target specific function call ABI handling is located in `rustc_target`. This PR moves the ZST handling to `rustc_target` so that all the target-specific function call ABI handling is in one place. In the process of doing so, this PR fixes#125850 by ensuring that ZST arguments are always correctly ignored in the x86-64 `"sysv64"` ABI; any code which would be affected by this fix would have ICEd before this PR. Tests are also added using `#[rustc_abi(debug)]` to ensure this behaviour does not regress.
Fixes#125850
Recent versions of wasm-tools are now Apache-2.0 or MIT or Apache-2.0
with the LLVM exception, rather than strictly Apache-2.0 with the LLVM
exception. The only component with the exception has moved to a new
dependency `wasi-preview1-component-adapter-provider`.
With the new resolver, a few dependencies get brought in twice with
different licenses. For example, all dependencies from `wasm-tools`
gained Apache-2.0 and MIT options, and with the v2 resolver we were
using one version from before and one version from after this change.
This made tidy's license check difficult.
Update some minimum versions to remove duplicate dependencies and smooth
out license checking.
Pinning the resolver to v1 was done in 5abff3753a ("Explicit set
workspace.resolver ...") in order to suppress warnings. Since there is
no specific reason not to use the new resolver and since it fixes
issues, change to `resolver = "2"` everywhere except library and
submodules.
Modifies `BikeshedIntrinsicFrom` to forbid lifetime extensions on
references. This static check can be opted out of with the
`Assume::lifetimes` flag.
Fixes#129097
Promote Mac Catalyst targets to Tier 2, and ship with rustup
Promote the Mac Catalyst targets `x86_64-apple-ios-macabi` and `aarch64-apple-ios-macabi` to Tier 2, as per [the MCP](https://github.com/rust-lang/compiler-team/issues/761) (see that for motivation and details).
These targets are now also distributed with rustup, although without the sanitizer runtime, as that currently has trouble building, see https://github.com/rust-lang/rust/issues/129069.
Add epollerr support
Fixes#3816
For socketpair, if the peer fd is closed while having data in its read buffer, ``EPOLLER`` will be thrown.
This is still WIP because I am currently finding a way to check if peer fd still has something in its ``readbuf`` when it is closed and add the ``EPOLLER`` flag In ``get_epoll_ready_events``.
Disable `dump-ice-to-disk` for i686-mingw (again)
To avoid blocking full CI or `i686-mingw` try jobs (failed in https://github.com/rust-lang/rust/pull/127679#issuecomment-2295184771).
At least we now have some context for why the assertion failed.
Anyone with r+ can approve this.
Remove `find_format_arg_expr` AST fallback
If the function fails where it shouldn't we can fix that directly, but the fallback path is untested as I'm not aware of a case where it would fail
changelog: none
