std: add platform support for hexagon-unknown-qurt by androm3da · Pull Request #152084 · rust-lang/rust

androm3da · 2026-02-04T04:50:05Z

QuRT provides POSIX-like APIs for basic operations, so this implementation reuses the unix platform abstraction layer with QuRT-specific customizations.

Platform modules:

New os::qurt module with platform-specific extensions to ffi, fs, io, raw
QuRT-specific file handling for ino, dev, mode, nlink, etc.

Unsupported: Networking, fork/exec, pipe, chown/fchown/lchown/chroot/mkfifo

This PR depends on a newer version of the libc crate - maybe I'll let this PR hang here for a bit and check back in when it gets released and promoted?

You need libc at 0.2.179, right? You can update libc here – but please keep it in a separate commit.

You need libc at 0.2.179, right? You can update libc here – but please keep it in a separate commit.

The commit I need - rust-lang/libc@9934c04 is not yet tagged/released. Or rather there is a ctest-* tag but I suspect that doesn't apply/not intended use for that tag. Should I try to execute a tag/release of libc, or just wait for that to happen naturally?

The libc 0.2 signature uses *const *const c_char while libc 1.0 uses *const *mut c_char (which is more POSIX-accurate). This cast allows CI to pass until the libc crate is updated. Remove this commit once libc with QuRT support is published.
