<div>
<pre>clang issues the following error message upon encountering constraint "=f":
error: invalid output constraint '=f' in asm
Rather than simply saying the constraint is invalid, it would be better to
print a message that informs the user how the error can be corrected. For
example, gcc prints the following message:
error: output constraint 0 must specify a single register</pre>
