+    qyieldcpu: Fix compilation with macOS 26.4 SDK
+    
+    After updating to the macOS 26.4 SDK, qtbase fails to compile on
+    Apple Silicon with an implicit function declaration error for
+    __yield() in qyieldcpu.h. It appears that the SDK's Clang now
+    reports __has_builtin(__yield) as true, but __yield() requires
+    <arm_acle.h> for its declaration.
+    
+    The compiler's own __builtin_arm_yield intrinsic was already checked
+    further down in the cascade. Moving it above the __yield check resolves
+    the build failure, without unnecessarily pulling in the header.
+    
+    Fixes: QTBUG-145239
+    Change-Id: I94b4d8f72385a4944c272ed7a66d249537a82e7d
