…ror-pattern` Resolves Issue rust-lang#118752
in particular, this makes the `c` feature for compiler-builtins an explicit opt-in, rather than silently detected by whether `llvm-project` is checked out on disk. exposing this is necessary because the `cc` crate doesn't support cross-compiling to MSVC, and we want people to be able to run `x check --target foo` regardless of whether they have a c toolchain available. this also uses the new option in CI, where we *do* want to optimize compiler_builtins. the new option is off by default for the `dev` channel and on otherwise.
Promote `riscv32{im|imafc}` targets to tier 2
Pending the approval of [the MCP](rust-lang/compiler-team#701).
…, r=davidtwco Switch from using `//~ERROR` annotations with `--error-format` to `error-pattern` Fixes rust-lang#118752 As noticed by ``@jyn514`` while working on a patch, tests failed due to `//~ERROR` annotations used in combination with the older `--error-format` which is now `error-pattern`.
…rors custom mir: make it clear what the return block is Custom MIR recently got support for specifying the "unwind action", so now there's two things coming after the actual call part of `Call` terminators. That's not very self-explaining so I propose we change the syntax to imitate keyword arguments: ``` Call(popped = Vec::pop(v), ReturnTo(drop), UnwindContinue()) ``` Also fix some outdated docs and add some docs to `Call` and `Drop`.
Use Result::flatten in catch_with_exit_code
Support reg_addr register class in s390x inline assembly In s390x, `r0` cannot be used as an address register (it is evaluated as zero in an address context). Therefore, currently, in assemblies involving memory accesses, `r0` must be [marked as clobbered](https://github.com/taiki-e/atomic-maybe-uninit/blob/1a1155653a26667396c805954ab61c8cbb14de8c/src/arch/s390x.rs#L58) or [explicitly used to a non-address](https://github.com/taiki-e/atomic-maybe-uninit/blob/1a1155653a26667396c805954ab61c8cbb14de8c/src/arch/s390x.rs#L135) or explicitly use an address register to prevent `r0` from being allocated to a register for the address. This patch adds a register class for allocating general-purpose registers, except `r0`, to make it easier to use address registers. (powerpc already has a register class (reg_nonzero) for a similar purpose.) This is identical to the `a` constraint in LLVM and GCC: https://llvm.org/docs/LangRef.html#supported-constraint-code-list > a: A 32, 64, or 128-bit integer address register (excludes R0, which in an address context evaluates as zero). https://gcc.gnu.org/onlinedocs/gcc/Machine-Constraints.html > a > Address register (general purpose register except r0) cc `@uweigand` r? `@Amanieu`
…uviper Remove libtest's dylib libtest.so is only used by rustdoc, and tests seem to pass locally with this change. I suppose if this is broken, the only way to find out is to make a PR.
Make offset_of field parsing use metavariable which handles any spacing As discussed at and around comments rust-lang#106655 (comment) and rust-lang#106655 (comment), the current arguments to offset_of do not accept all the whitespace combinations: `0. 1.1.1` and `0.1.1. 1` are currently treated specially in `tests/ui/offset-of/offset-of-tuple-nested.rs`. They also do not allow [forwarding individual fields as in](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=444cdf0ec02b99e8fd5fd8d8ecb312ca) ```rust macro_rules! off { ($a:expr) => { offset_of!(m::S, 0. $a) } } ``` This PR replaces the macro arguments with `($Container:ty, $($fields:expr)+ $(,)?)` which does allow any arrangement of whitespace that I could come up with and the forwarding of fields example above. This also allows for array indexing in the future, which I think is the last future extension to the syntax suggested in the offset_of RFC. Tracking issue for offset_of: rust-lang#106655 `@rustbot` label F-offset_of `@est31`
stop feed vis when cant access for trait item Fixes rust-lang#119463 It's not necessary to feed visibility when use a private trait. r? `@petrochenkov`
…tins, r=onur-ozkan Reland optimized-compiler-builtins config Copy of rust-lang#102579 PR. From rust-lang#102579: > No concerns on my side. Currently, Jyn isn't actively working on the project. I will close this PR; open another one to cherry-pick the commits, resolve conflicts, and then r+ it. > Fixes rust-lang#102560. Fixes rust-lang#101172. Helps with rust-lang#105065 (although there's some weirdness there - it's still broken when optimized-compiler-builtins is set to true). Fixes rust-lang#102560. Fixes rust-lang#101172. Helps with rust-lang#105065 r? ghost
