6.7.5. -fno-trapping-math

From the GCC documentation:
“Compile code assuming that floating-point operations cannot generate user-visible traps. These traps include division by zero, overflow, underflow, inexact result and invalid operation. This option implies -fno-signaling-nans. Setting this option may allow faster code if one relies on “non-stop” IEEE arithmetic, for example.”

Programmers are recommended to experiment with this option to determine how it affects their code.
