swift build ${BUILD_SYSTEM_FLAGS[@]+"${BUILD_SYSTEM_FLAGS[@]}"} --configuration release -Xswiftc -no-whole-module-optimization
# Whole-module optimization is left at the release default. It was disabled
# here in August 2025 to dodge a build hang on the toolchain of the day; that
# hang no longer reproduces, and the workaround now breaks the build outright:
# Xcode 27 makes SwiftPM's newer build system the default, and that system
# fails to emit the per-file dependencies output the flag implies
# ("unable to open dependencies file ... -primary.d"). Restoring the flag
# therefore also means forcing --build-system native, which is deprecated and
# slated for removal. If the hang ever returns, that pair is the fallback.
