- Adds option to rustc config to enable GCS - Passes `guarded-control-stack` flag to llvm if enabled
This test currently only runs on RISC-V and loongarch hosts, but assumes that the host target is the -gnu target. By using minicore, we can run this test on all host targets, regardless of architecture, as long as the LLVM components are built. This also fixes this test on musl hosts of these architectures.

and double-check that we match it in codegen
Since PeekMut implements Deref, it shouldn't have any methods of its own. See also: `std::collections::binary_heap::PeekMut::pop`
readdir_r has the same problems on FreeBSD as it does on other platforms: it assumes a fixed NAME_MAX. And readdir has the same thread-safety guarantee as it does on other platforms: it's safe as long as only one thread tries to read from the directory stream at a given time. Furthermore, readdir_r is likely to be removed for FreeBSD 16, so we should stop using it now.
Despite that the `fflags` register (representing floating point exception flags) is stated as a flag register in the reference, it's not in the default clobber list of the RISC-V inline assembly and it would be better to fix it.
GCS support was added to GCC in version 15, thus the rmake test for this patch requires GCC15
…ble-GCS, r=Urgau Extends AArch64 branch protection support to include GCS Extends existing support for AArch64 branch protection to include support for [Guarded Control Stacks](https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/arm-a-profile-architecture-2022#guarded-control-stack-gcs:~:text=Extraction%20or%20tracking.-,Guarded%20Control%20Stack%20(GCS),-With%20the%202022).
…est, r=Mark-Simulacrum tests/codegen-llvm: Make rust-abi-arch-specific-adjustment portable This test currently only runs on RISC-V and loongarch hosts, but assumes that the host target is the -gnu target. By using minicore, we can run this test on all host targets, regardless of architecture, as long as the LLVM components are built. This also fixes this test on musl hosts of these architectures (though I've only tested on loongarch64-unknown-linux-musl).
interpret: fix overlapping aggregate initialization This fixes the problem pointed out by ```@saethlin``` in rust-lang#146383 (comment). Also clarify when exactly current de-facto MIR semantics allow overlap of the LHS and RHS in an assignment.

…ber-float-flags, r=Amanieu rustc_codegen_llvm: Adjust RISC-V inline assembly's clobber list Despite that the `fflags` register (representing floating point exception flags) is stated as a flag register [in the reference](https://doc.rust-lang.org/reference/inline-assembly.html#r-asm.rules.preserved-registers), it's not in the default clobber list of the RISC-V inline assembly and it would be better to fix it.
…-errors Note some previous attempts to change the Default impl for `[T; 0]` Recently, rust-lang#145457 experimented with changing the Default impl for `[T; 0]`. Subsequently, rust-lang#146531 also aimed to perform a similar experiment. It seems like a good idea to add some links to the relevant source code, so that the historical context of this tricky topic is easier to find.
fix 404 MCP link I think this is what this should point to. The old link did a redirect, so one could also fix the redirect, but i wasn't able to find where the redirect target is defined.

Switch `std::vec::PeekMut::pop` from self to this parameter. Since PeekMut implements Deref, it shouldn't have any methods of its own. See also: `std::collections::binary_heap::PeekMut::pop` Pointed out: rust-lang#122742 (comment) Related: rust-lang#122742
…mulacrum On FreeBSD, use readdir instead of readdir_r readdir_r has the same problems on FreeBSD as it does on other platforms: it assumes a fixed NAME_MAX.

…mental, r=Kobzol bootstrap.py: disable incremental build for bootstrap in CI locally this seems to save a quarter of a second per build of bootstrap, presumably mainly because it avoids writing 280MB to disk. unsure if this is worth two extra lines of python, i'll let t-bootstrap decide.
