Hi Øyvind

Yes, you are right, we don’t use wchar_t within TF-M and it does seem a trivial optimization without much benefit for TF-M other than introducing incompatibilities. Could you submit a patch to remove the same from GCC and ARMCLANG ?

Best Regards

Hi guys. I’m curious why -fshort-wchar is enabled for ARMCLANG and GNUARM (not IAR, interestingly). This should have little or no impact since wchar_t is so rarely used, and causes incompatibility when I try to link my Zephyr app with TF-M libs.
