Expose `ucred::peer_cred` on QNX targets to enable dist builds After following https://doc.rust-lang.org/rustc/platform-support/nto-qnx.html I attempted to run the following `x.py` command: ```bash export build_env=' CC_aarch64-unknown-nto-qnx710=qcc CFLAGS_aarch64-unknown-nto-qnx710=-Vgcc_ntoaarch64le_cxx CXX_aarch64-unknown-nto-qnx710=qcc AR_aarch64_unknown_nto_qnx710=ntoaarch64-ar CC_x86_64-pc-nto-qnx710=qcc CFLAGS_x86_64-pc-nto-qnx710=-Vgcc_ntox86_64_cxx CXX_x86_64-pc-nto-qnx710=qcc AR_x86_64_pc_nto_qnx710=ntox86_64-ar' env $build_env ./x.py --stage 2 dist rust-std --target aarch64-unknown-nto-qnx710,x86_64-pc-nto-qnx710,x86_64-unknown-linux-gnu ``` The result was the following error: ``` Compiling object v0.32.2 Compiling std_detect v0.1.5 (/home/ana/git/rust-lang/rust/library/stdarch/crates/std_detect) Compiling addr2line v0.21.0 error: function `peer_cred` is never used --> library/std/src/os/unix/net/ucred.rs:89:12 | 89 | pub fn peer_cred(socket: &UnixStream) -> io::Result<UCred> { | ^^^^^^^^^ | = note: `-D dead-code` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(dead_code)]` error: could not compile `std` (lib) due to 1 previous error Build completed unsuccessfully in 0:06:25 ``` I contacted `@flba-eb` and `@gh-tr` over email and we confirmed that `peer_cred` here should be flagged on `nto` targets. This should enable the clean `x.py --stage 2 dist rust-std` command on these platforms. |
