# Qt's qyieldcpu.h (through 6.9.x at least) calls the ACLE intrinsic
# __yield() under __has_builtin(__yield) without including
# <arm_acle.h>. Apple clang 21 reports the builtin as available but
# makes the resulting implicit declaration an error, so every
# translation unit that reaches <QtCore/qatomic.h> fails to compile.
# Force-including the ACLE header supplies the declaration.
