`%swift-frontend` is not a Lit substitution; `%swift` is. Because it starts with `%swift`, Lit expanded that prefix and left a bare `-frontend` behind, which concatenated onto the last argument of the `%swift` expansion -- the final `-define-availability` value -- rather than becoming an argument of its own. These tests have therefore been running with a corrupted availability macro. Nothing failed while the `%swift` expansion ended without whitespace. Once it gained a trailing space in https://github.com/swiftlang/swift/pull/91891, `-frontend` became a separate argument, and `swift-frontend` honors it only in first position, so the tests began failing with: ``` <unknown>:0: error: unknown argument: '-frontend' ``` Likewise, spell `%swift-frontend-plain` as `%swift_frontend_plain`.
