Hi, We are using gcc-arm-9.2 toolchain and see that this is not supporting the "xpaci" instruction. Is there any compiler flag that has to be included to support this?
Reference code that uses "xpaci" when PAUTH is enabled - https://github.com/ARM-software/arm-trusted-firmware/blob/master/bl31/aarch6...
