Using armclang compiler v6.22 for an stm32f4 (Cortex-M4) processor. It appears that there's a compiler option -Wnan-infinity-disabled that's causing these functions to not work (substitutes with 'false'). I don't see this option in the Keil uVision settings to turn it off. Is there a way to disable this option? I've tried every optimization setting to no avail.
