CC2642R: Whther TI SDK v5.10 can be used for building TI BLE application using armcl compiler with -fstack-protector compile option

I am using the TI SDK v5.10 building BLE stack. By default, the project uses armcl compiler (ti-cgt-arm_20.2.4.LTS) from the CCS v10.3. 

I was wondering if any of the example BLE project can be built with compile time options like "-fstack-protector" using armcl compiler? Whether TI recommands to use this option? I tired definign this option in the projectspec file and then while importing, I have got an error that this option is not recognized:

I was gogin through few materials from TI and have found that above compile time option is available in tiarmclang compiler but not in armcl compiler?

Also, TI mentioned that the armcl compiler will not longer be updated unless for bug fixes and instead, the developers should use a new tiarmclang compiler. Is my understanding correct?
