+    Disallows implicit floating-point code. This inhibits optimizations that
+    use floating-point code and floating-point/SIMD/vector registers for
+    operations that are not nominally floating-point. LLVM instructions that

 ``noinline``
     This attribute indicates that the inliner should never inline this
     function in any situation. This attribute may not be used together
