<pre>I received this bug report by email,
<a href="https://godbolt.org/z/1KnfbE">https://godbolt.org/z/1KnfbE</a>
In this example, #pragma clang fp reassociate on line 1 is applied in a global
scope; however, you will notice that there's no "reassoc" notation in the fadd
operation for struct MyComplex.
Similarly, applying the pragma right above the struct declaration like
MyComplex3 will not work either.
The only working case is to add it in the add operation right above the return
statement, as you can see in MyComplex2.</pre>
