function name by appending "__builtin_" to it. This behaviour may
be unexpected, so enabling this will produce a diagnostic when
such a function is resolved to a builtin.
+.It Fl W Ns Cm inexact-compares
+When comparing an inexact value such as `1.0/3.0' the result is
+pathologically wrong. Enabling this will trigger a compiler warning
+on such expressions.

The desired fps can be set via -state-fps=NUM, defaults to 10.
Specifying \-state-fps implicitly sets this flag. Defaults to off in all
standards.
+.It Fl f Ns Cm arithmetic-exceptions
+Turn on arithmetic exception tests in the compiler. In constant expressions
+which trigger exceptions like division by zero, overflow, underflow, etc,
+the following flag will produce diagnostics for what triggered that
+exception.
