Clang 21 enabled built-in support for "__yield" but requires including "arm_acle.h" to work. Qt's "qyieldcpu" header will emit code using the function without including the declaration and thus fail compilation A fix for Qt is pending, but AppleClang 21 is shipped since 2026-03-24 with Xcode 26.4 and thus the project cannot be compiled after a toolchain update otherwise.
