This force-unwrap works fine on linux too, but I separated it out anyway in case there is concern it breaks other platforms.

I see this done elsewhere in this repo so should be fine, doing the force unwrap on all platforms now.

ArraySlice currently never passes a buffer with a nil baseAddress. It's arguably an implementation detail, but we rely on it in many places.

OK, I only modified this because the compiler complained and errored. Is there something you'd like me to change here?

No, I just wanted to further clarify why the force unwrap is correct here.

I didn't bother separating this out into a guard let since it's just for the tests, can do so if wanted.

Why not merge these two lines?

| guard let fp = fpo else { | |

Good point, will change.

What about stdinUnavailable? "not opening" is not particularly descriptive, and makes you question what happened.

Rebased and made the changes asked for, plus fixed an Android test. |

@kateinoigakukun, can I get a CI run here? |

@swift-ci Please test |

This is needed because Bionic recently added a bunch of these annotations. I made sure this pull doesn't break anything by testing it on linux x86_64 and with the previous NDK 25c also. I used this patch with others to build the Swift toolchain for my Android CI, finagolfin/swift-android-sdk#122, and the Termux app for Android, which now uses NDK 26b.
