This will let people make calls like random(1..=6), and allows for future expansion to non-uniform distributions, as well as floating-point. For now, this is only implemented for `RangeFull`, to get the interface in place. Subsequent commits will implement it for other range types.
Clarify and expand documentation for std::sys_common dependency structure This PR makes a minor improvement to the module-level documentation of std::sys_common: Replaces the lowercase “dag” with the more standard and explicit form “DAG (Directed Acyclic Graph)” for clarity.

This CI workflow will run the https://github.com/rust-lang/josh-sync tool on Mondays and Thursdays. It will try to do a pull (sync stdarch changes from rust-lang/rust into this repository). When it runs, three things can happen: - There are no rustc changes to be pulled, the bot does nothing. - There are some new changes to be pulled. In that case, the bot will either open or update an existing PR titled "Rustc pull update" on this repository with the changes. After the PR is merged, we should ideally do the opposite sync (push) manually. - The pull fails (usually because of a merge conflict), or the bot determines that a pull PR has been opened for more than a week without being merged. In that case, it will post a ping to https://rust-lang.zulipchat.com/#narrow/channel/219381-t-libs/topic/compiler-builtins.20subtree.20sync.20automation/with/528482375.
std: move NuttX to use arc4random for random number generation arc4random support in libc merged in rust-lang/libc#4464, so: * Move `target_os = "nuttx"` from unix_legacy to arc4random section * This aligns NuttX with other POSIX-compliant systems that support arc4random * Improves random number generation quality on NuttX by using the system's built-in arc4random implementation instead of legacy fallback methods NuttX supports arc4random_buf which provides better entropy and security compared to the legacy random number generation methods.
…ompiler-errors New tracking issues for const_ops and const_cmp Let's do a clean start with new tracking issues to avoid mixing things up with the previous constification. I assume the fact that the `PartialEq` *trait* and *impls* used different feature names was a mistake (the feature name on the impl is entirely irrelevant anyway). Part of rust-lang#143800, rust-lang#143802 r? ``@oli-obk``

Fix typo in `DropGuard` doc Follows-up rust-lang#144236 (I happened to see the typo yesterday but didn’t think it should delay the PR’s merge so I kept quiet, sorryyyyy).
Faster equality compare Add tests Add missing files for tests

Fix Ord, Eq and Hash implementation of panic::Location Fixes rust-lang#144486. Now properly compares/hashes the filename rather than the pointer to the string.

Implement `push_mut` Implementation of rust-lang#135974.
It adds feature detection of 1 extension (new in std_detect). New RISC-V Extension: 1. "Zabha"
…Amanieu Make `libtest::ERROR_EXIT_CODE` const public to not redefine it in rustdoc I think it's better to make this constant public so it can be used by crates using `libtest` as dependency. As a side-note, I will update rust-lang#143900 to make use of this constant once this is current PR is merged.
…manieu `std_detect`: Linux 6.16 support for RISC-V It adds feature detection of 1 extension (new in `std_detect`). New RISC-V Extension: 1. "Zabha"
