Enable segfault / bus error handlers on more UNIX platforms #25872

Open geofft opened 9 years ago

geofft commented 9 years ago

src/libstd/sys/unix/stack_overflow.rs is enabled on Linux, OS X, Bitrig, and OpenBSD targets only, because the implementation used to have its own signal-handling bindings that were only known to be correct on those targets. In #25784 I refactored the bindings and verified them for all current ports, I think we can turn this on on all current ports. This would enable handlers on Android, iOS, FreeBSD, and Dragonfly.

I don't have easy build infras for these myself, so I'm probably not going to do this immediately. But if someone wants to test one out and make sure that it works, I think it's just a matter of adding an OS to the #[cfg] and writing a program that segfaults.

Linux, macOS, Bitrig, Dragonfly, FreeBSD, Solaris, NetBSD (but not vendor = rumprun), and OpenBSD currently have the impl enabled. It seems that only Android and iOS are left to be enabled here, so removing the A- tags that are non-relevant any more.

Triage: no change

In https://github.com/rust-lang/rust/pull/125226, while I believe they could fairly easily be implemented on iOS, tvOS, watchOS and visionOS, instead of enabling them I've gone with documenting why we don't; they might lead to rejections from the App Store.
